Are you afraid that if another machine connects to your router, that the port forwarding needed for your private server will point to it rather than the intended machine? This is possible, but you can prevent it from happening. You will want to make sure that only the machine that you use as a private server can be assigned the IP address that the port is being forwarded to. This feature is called "Address Reservation" on your router. You will need to put in the IP address you want to use for that machine, the MAC address of the machine (you can find this in the Attached Devices menu), and click apply. After you set that up, reboot your private server machine just to make sure that everything works properly.
You need to get a broadband router in order to avoid this problem. I could go into gory details if you'd like, but the basics is as follows. Your ISP is only handing out one IP with your internet connection. This IP is being flipflopped between the two devices. If you get a router, this problem will go away since the router will use the ISP's IP and will hand out private LAN IPs for the different devices that are attached to it.
Ahh... Tricky question. When I first read the question, I thought, "nope, that's the way you make a bus topology network", but I was wrong. Technically, a series of computers all connected to a hub using CAT5 cable is using bus topology. The reason for this is simple. In a bus-based network design, all the systems on that network are connected to a shared communication "line". When a device sends data on this shard communication line, all the other devices receive that data, but only the machine that the data is intended for will pay attention to the data sent. This is exactly what a hub does. In essence, the hub is doing the same thing as that single cable that all the machines connected to with t-connectors. A hub is nothing more than a repeater; data comes in on one port and the hub repeats this data to all the other ports. So, technically, a network consisting of nothing more than hubs is a bus topology network.
In order to truely have the functioning behavior of a star topology network, you would have to use a switch, which only sends data to the intended recipient rather than repeating it to every device.
As for whether or not it is possible to attach a network using coax to a network using CAT5, you can. You will need to get an intermediary of sorts. This intermediary will have the ability to connect to both the coax-based network and the …
Your question is very poorly worded. Even inferring what you are wanting doesn't give enough information to give a satisfactory answer. I could write a book just to try to answer your original question and would still only scratch the surface of the topic.
Try asking some questions that can be answered simply. Questions like these are better suited for a forum:
What equipment is needed to wire up a network that will connect thirty lab computers, 3 network printers, and a file server? This setup will be no frills, so just basic equipment will fit the job.
Can anyone provide me with information or links to information about how to install networking cable in a room without having to open up the walls? This will be for a classroom setting, so safety is a concern.
At what point does a network need enterprise-grade equipment and cabling? In other words, how many systems can standard home/small-business-grade equipment handle?
Is it reasonable to set up a computer lab using only wireless connections, or would it be better to find a way to run cables throughout the room? The room is older, so there aren't any conduits that can be used to run the cables through and there will be desks set up along the walls as well as occupying the center of the room.
Notice that I gave some additional information along with the question. There are many, many variables to consider when planning a network design: …
w1r3sp33d, Turning off the SSID broadcast is a bad idea. If I turn off the SSID broadcast, none of the clients will connect to the router anymore because Microsoft in its infinite wisdom handicapped the WZC. Here's the gist of the problem. If you turn off the SSID broadcast, configure the client to connect the SSID by setting a connection to the SSID, and then try to connect while there aren't any unsecured APs in the area, it will connect just fine. But... throw in an unsecured AP (many of which exist around our apartment), and the client will connect to the unsecured AP rather than the AP that you configured it to connect to. Think I'm kidding? Read this. Pay special attention to the "This behavior is by design" line. They also indicate the reason that they added this "design feature". It's because Microsoft feels that it is a poor security measure, so it should not be used. This made me very mad at Microsoft since it adds a security hole. If you connect to an access point with the SSID broadcast turned off while on a machine running Windows XP and you are away from other APs, someone can hijack your connection by just running an unsecured AP near your machine. This would allow them to inspect your traffic if they set it up that way. It would also give them access to your network neighborhood and any unsecured files that you have. Sounds like …
Hey guys. I need some serious help with a problem that is seriously driving me nuts. If you don't care about my setup, skip down to the problem to see what I want help with.
The Setup Here are the basics. I live in a two-story townhome apartment. There are three rooms: one large room downstairs with two people in it and two smaller rooms upstairs with one person each. I live in one of the upstairs rooms. I have multiple machines in my room that must be connected together with a switch of some sort since the amount of traffic between my machines is so high that the wireless speeds would unsatisfactory and the wireless network would get bogged down by the traffic.
We currently have a D-Link DI-612 as the focal point of our network. I have three machines in my machines that are connected with wires. The other upstairs room has one machine connected wirelessly with a D-Link DWL-G510. The downstairs room has two machines that run a D-Link DWL-G132 and a Zonet ZEW2501.
The router is currently set to use Channel 1 as almost all of my neighbors with routers use Channel 6 and a couple use Channel 11. We have a total of three cordless phones that operate in the 2.4GHz range.
The Problem These are the symptoms that I experience:
Whenever a cordless phone is used near (within a …
Not a clue. I'm not certain if you gave the exact message given. You have typos in the first line, so I have reason to believe that you are paraphrasing the message rather than giving the exact wording of the message. Without the exact letter-for-letter message, it's hard (or in this case impossible) to search for information about it.
I really respect the guys that run that site, but this article is just laughable. I'll openly admit that I am an avid Firefox user, but my issues with the article have nothing to do with my affinity for Firefox.
My beef with the article is that the writer correctly and validly points out the fallacies of the myths but does not specify where the myth came from by providing a balanced interpretation. Since I am somewhat bored, I guess I will make my own list.
"Firefox has lower System Requirements than Internet Explorer" I don't know who claims this since its very easy to see that Firefox can be a very big memory hog and is just as bad as IE when it comes to completely locking up all the CPU cycles from time to time without reason.
"Firefox is faster than Internet Explorer" It is true that people claim this, but it is an example of taking a concept out of context. While it is true that IE cold starts faster than Firefox (especially if you have Firefox tricked out with a bunch of extensions), I don't know who cares about cold start times. The speed people are referring to is the perceived speed with which Firefox browses and renders when compared to IE. The actual speed of the page loads and renders are varied and can be shown to favor either IE or Firefox, but that doesn't refute the fact that many users …
The most likely cause of your slowdown and connectivity issues is a lack of maintenance. Do you ever run antivirus and antispyware scans? Do you clean out your old files to make sure you have some spare room on your harddrive? Do you run programs to clean out your Registry and optimize system settings? Assuming that you run Windows XP, follow the steps in this guide to start cleaning up your machine. This will help you get back to that "new machine" feel.
Keep in mind that a system is only capable of running so much without getting sluggish. If your machine feels slow, you could be demading a lot more out of it than you used to. The type of programs you decide to run in the background can take up a lot of processor time and memory. What programs do you run to play your music and do your downloads?
Since you multitask, having sufficient RAM is crucial. The bare minimum amount of RAM most people should have now is 512MB and at least 1GB is recommended. So, if you are looking for a starting point to tweak your system, start with your RAM.
You have a 40GB harddrive and say that you are low on space? What does low mean to you? 5GB free? 1GB free? 100MB free? 0MB free? You say that you wouldn't buy a new harddrive unless you bought a new machine. Why is that? You can get harddrives …
Knowing which processor you currently have doesn't give us enough information to determine which processor is the fastest one that your board can support.
This is some advice for you. Please don't take it as an insult. If you don't know enough about your system to know how to determine what processors are compatible with it, you shouldn't be trying to upgrade it. Laptops are very delicate machines that are not at all forgiving. If you don't have experience working with machines, you can damage your laptop while trying to perform the upgrade.
You're the only one that can determine whether the cost and trouble of upgrading is worth it. If you really don't want a newer machine because your current machine is almost doing everything you want, then by all means, save yourself a lot of money and upgrade the RAM.
As for the harddrive, I can never see buying additional storage as a bad thing. If you buy an additional harddrive and then end up getting a new system later on, that harddrive isn't wasted since you can just throw it in the new machine. This can't be said about RAM since adding older memory to a newer system will slow most likely slow the machine down.
Are you looking to upgrade the processor? If so, we need additional information. The ZE4500 doesn't have a specific set of hardware components since it is a customizable setup (I've even seen ZE4500s with Intel chips rather than AMD). Run Everest and give us all the details relating to your motherboard. This will help us answer your question.
On a side note, why are you looking to upgrade? What are you wanting your machine to do that it doesn't currently? Or are you just looking to get a bit more speed out of it?
Sounds like you have Scroll Lock turned on. Excel is one of the few programs I can think of that has ever made any use of that useless keyboard function. Turn Scroll Lock off, and your arrow key functions should return to normal.
Yes, a CAT5 cable can also be referred to as an ethernet cable or a wider phone plug. Saying CAT5 is just one of those technically-accurate ways of saying the specific type of cable.
Just plug in the cable from one of the LAN ports on the back of the router to one of your machines, reboot the machine, and then do the configuration.
BILL S, you've talked about a very similar subject in two different places, making it hard to respond to your concerns.
You say that you have a 9250 and are disappointed by its performance. You also say that you looked around and it had the highest "numbers", so it should have been the best. This is a good lesson time. Higher numbers does not mean faster performance. Higher model numbers when comparing products from different manufacturers will never give you a good comparison. More and more, comparing model numbers between cards made by the same manufacuturer doesn't give you a means to compare performance.
The 9250 is an older card and was developed to be a low-end graphics solution. In essence, it was developed to be used as a graphics solution for offices and productivity software users that don't work with demanding multimedia applications.
The fact that a card has a DVI output doesn't mean that it is created for performing advanced rendering; it simply means that the card can output a true DVI signal for use on better LCD monitors and other displays that support DVI inputs.
If you truely want to find out what a card is made to do and what you can expect out of it, find sites that benchmark cards and see what they say about the card you want to get. In other words, do your homework. It's sad that you can't just look at a model number and know …
So now you have a wireless router that is connected to your new modem and you have two wireless systems trying to connect to it?
If you read the details in the manual on setting up your router, you will notice that you need to have a machine directly connected to the router with a CAT5 cable in order to configure the router. You will need to connect one of your machines to the router with a cable, reboot that machine, and then follow the instructions for setting up the router.
I don't think that you will find an easy solution to this issue without aid from the librarians. There is only so much that you can do to fix a problem on a public machine without violating the terms of use. This is a good example of when Social Engineering is more valuable than technical know-how.
Tell the librarians that your security is at risk and so is their network since the version of Firefox is severely outdated (the current version is 1.5). Furthermore, tell them that it is very easy to update Firefox. All they have to do is log into the computer as a user that has priviledges to update the software (since I assume that they have the systems locked down), load Firefox, click Help, and select "Check for Updates". This will download and install the updates. All that they have to do is click a few buttons, and Firefox will update itself.
Just keep track of the error descriptions. Make sure that you record the whole description and not just parts of it. The data would take a long time to record and wouldn't mean a whole lot to most people.
Create a folder for qBasic somewhere (such as C:\qbasic) and place the downloaded file there
Open a command prompt, navigate to the folder that you placed the file in, and run the program. After the program runs, you will have qBasic installed on your machine.
170 degrees Farenheit is approximately 77 degrees Celcius. Your system is running very hot. Ideally, your system should run less than 60 degrees.
You don't set the temperature. The temperature is a readout of what is happening with the system, not a setting that you can modify by playing around in your BIOS settings.
You keep talking about your power supply, but I don't believe that it is the issue. You mentioned that your computer kept restarting before you replaced the power supply and that it still does, which means that the restarting issue is not likely to have anything to do with your power supply. Before you replaced your power supply, did you check the temperatures? I'm sure that the temperature is the main issue with your system shutting off, and I'm sure that the temperature was the issue before you replaced your power supply.
You mention that you have done many upgrades to your system. Have you ever replaced the CPU or the heatsink for it? Think about if your shutting off issue started shortly after you removed and reinstalled the heatsink. If you didn't properly install the heatsink on the processor or have installed a poorly designed heatsink, your chip will overheat.
All drives wear down over time. Sometimes it just happens faster than normal. There are a slew of potential causes, but it seems to usually happen because of a manufacturing defect of some kind.
Sounds like your drive has the "click of death" syndrome, which means that drive is most likely going out. Call Dell tech support and see if they can offer you any warrenty service. If they can't, you will want to buy a new harddrive and replace it.
You need something to initiate a SMTP connection in order to send mail. The only versions of Windows that have this ability built-in are Professional or Server versions.
There's some good news though. There are many places to get programs that can send SMTP mail. I recommend using Blat. It's free, easy to configure, and easy to use.
See if you can browse the other machines shared files by refering to its IP address in explorer. Use the following format "\\ipAddress", such as "\\192.168.1.101". If it works, you should see the shares available on that system.
Flash drives don't "open". Can you describe the windows that are popping up? Usually when you first attach a drive, it quickly scans all the files on the drive to see what type of files are contained on it in order to provide different opens like play movies or play audio. When this scan occurs, a small window with a progress bar quickly pops up and shows the progress of scanning the files.
After the drive is attached, can you see the drive listed in Explorer as an available drive?
There are a number of different solutions for your problem.
The easiest solution is to replace the RT31P2 with a switch and connect the cable modem to the WRT54G. This would create one LAN rather than the two LANs that you currently have. This isn't a very good solution though since you would have to replace a component.
Your computers may be able to share files across the different LANs currently, but they just don't see eachother in Network Neighborhood. To test this, use one of the computers to try to access the shares on a computer that is connected to the other router. Rather than going through Network Neighborhood, type in the location of the other computer in the form of "\\ipAddress" such as "\\192.168.1.101". See if you can see across to the other router's systems this way. If this set up works for you, you could actually make links on each machine to point to the systems on the other router. It's not the most elegant solution, but I have seen it work.
Now for a solution that is both elegant and inexpensive (free) but is also more technically involved. This is the best solution I can come up with in your situation. Basically, we will turn your wireless router into nothing more than a switch with a wireless access point. In effect, this will bypass all the router functions -- NAT, firewall, DHCP server, etc -- on the wireless router. …
Actually, the package format that Ubuntu uses is the same as Debian. The Ubuntu team does develop some of their own packages however. You can find more information about the relationship between Debian and Ubuntu here.
The relationship between a distro and that distro's code base are always different. To find out the similarities and differences between different distros, go to that distros website and look around.
You say that the temperatures are nowhere near overheating, but what were the temperatures?
Many newer motherboards allow you to set a temperature that will cause the system to shut down instantly if the chip gets that hot. Check your BIOS and ensure that this isn't what's occuring.
I can't think of a single distro that has not been built starting with a code base from some other distro. A very popular Linux distro is Slackware, and there are dozens of distros that are based off of this code. The reason for this is simple: why start from scratch when you can start from a tested and proven code base that has most of the features that you like? Ubuntu isn't Debian, only Debian is Debian, but Ubuntu started with a base of Debian code because the creators of Ubuntu liked the core concepts of Debian and wanted to implement those in their distro.
A good analogy for this is Firefox. Firefox wasn't written from scratch; rather, it was started from the code base of Mozilla. Firefox isn't the only software that is based off of Mozilla code; Netscape, Camino, Flock, and other browsers have all been built from a base of Mozilla.
You may think all this sounds odd, but it happens all the time in open-source software development.
You mentioned that it's not letting you press enter. How far along can you get? What is the last thing you can get to and are you shown any errors when you get there?
I use Hotkeycontrol XP. This program lets you assign all sorts of hotkeys to do stuff that isn't typically exposed in the Windows interface. I have hotkeyed Win+Z to sticky/unsticky windows. This makes forcing a window to stay on top fast and easy. Give it a try.
Can you provide a list of programs that you are trying to install?
From the bit of searching that I've done, it seems that you are probably trying to install software that was designed from Windows 95 or 98. If this is the case, you will probably need to contact the software vendor to see if there are any updates/patches that you can use to install the software on XP.
anything about the color scheme or display resolution?
The driver is what allows the system to produce higher resolution images with higher bit depths. In other words, update your driver first, then reboot your system, and let us know if it helped.
Your motherboard seems to be running at a good temperature, so I don't think that case ventilation is your issue; rather, there has to be a problem with the way your processor is having heat removed from it. There are many things that can cause this.
Did you install the heatsink on the processor yourself? Is your heatsink stock (in other words, is it the heatsink that came with the processor)? Has the heatsink ever been removed and reinstalled? Does the heatsink need to be cleaned?
Define eratically. For example, is the cursor jumping around in different directions than where you are trying to move it, is the speed of the cursor changing randomly, does it just stop fuctioning?
Justin01, he mentioned that he has System Restore disabled.
jaishankar, try running BootVis. Follow the instructions on that page to get the most out of it. Let us know if this addresses any of those issues you are having.
