The question is "could I" and not "will it work?" The answer is you could. And in fact given the wide variations of such schemes it may or may not work. No one will be able to tell you except the department that runs the network. But could you connect such a thing? Yes.


My dorm wifi is very bad, and it runs over a network that is supplies online through my Campus net where you put your MAC Addresses of your devices in order to connect, could I connect a MAC address of a WiFI router in order to establish a connection for it


Off topic but I have to ask:-

My wife's health is such that she would like to remove the presence of WiFi signals in the house if possible. This isn't as ludicrous as it sounds

You do realise that WHO (and countless other bodies) have found no link between WiFi signals and bad effects on health, unless the wifi switch you are using is not compliant with the local standards.


While you have a managed switch you don't seem to have an appliance to manage bandwidth per user.

I don't see what you think your options are but will give a nod to implementing a SQUID server for your users. It has many features that I won't get into here or later. But it does seem to be a great solution as not only the bandwidth control but caching to maximize your internet connection.

Need more information? Use the usual search engines and http://www.squid-cache.org/

Again, there are discussions about bandwidth control with this appliance.


Can somebody give me an advice of resolution.I have 1GBPS Bandwidth speed for my Internet Cafe. I have 31 Desktop PCs I have a managed network Switch that my 30 computers are connected on the Switch plus 1 Network Video Recorder for my CCTVs

My router has 2 LAN cables on the back 1 for the PC where the computer controls and monitors the activity of the 20 computers and has control to the CCTVs and 1 NVR
The Problem is Let us say one PC is downloading a huge File (e.g. Video or Software app) the other PC will have greater PING and will have lower speeds on the other PCs that only streams on the web.

Please help me.


FYI (if anyone was wondering) I found a solution and this is it:

I replace both routers with a single Asus running Merlin (enhanced Asus-wrt) that supports OpenVPN with routing rules. Now I just need that one router (so no LAN problems) and use outbound VPN rules so that only the TV devices use the VPN

That's the ticket. Fix this at the router level.

This area can upset folk. That is, if we break the VPN like this, it's not really a VPN but more of a proxy. That out of the way, some routers let you setup your LAN to VPN to where you wish. But breaking the VPN is well, another thing altogether.

To date I've kept the VPN true and don't accept such breakage to be acceptable and call it a VPN.

But as we see when reading priors at https://www.google.com/search?q=local+lan+access+when+using+VPN to break this (or some may calling fixing it) what you use for VPN matters as each system varies.


Hi Guys. I knw what I want to achieve but not how to achieve it! Any hints would be gratefuly received, or, if it's not possible, tell me so I can stop trying.

I have an internet connection -> router with NAT, DHCP etc -> LAN with all kinds of switches and WiFi access points all on the same subnet.
I have a couple of TV devices that need to access the LAN and also access the internet via a VPN for access to the right countries.
So I connected a VPN router to the LAN and the TV devices to that router. Now all the TV traffic goes via the VPN - so far so good. But the VPN router also VPN's access to the local LAN addresses, so they are inaccessible.
I've fudged it for the moment with a physical 2-1 ethernet switch so I can switch the TVs direct to LAN or via the VPN router, which works, but obviously isn't a good solution.
What I think I need is a router to hang off my my LAN that will simple pass all local traffic but route all other addresses via the VPN.
Is there such a thing? Or is the another way to do it?


@P, since you revealed nothing about your internet setup or location it is anyone's guess why your PC does this. Only the picture tells me this is some PC. Think of all the details required to work your issue.

Then we have countries and ISPs that block content. Also you could be at work or school that blocks YouTube. While I will not help folk get around work and school blocks do try Opera. Turn on the VPN in Opera and see what happens.


I have a question. Whenever I try to open youtube up, it shows up like this(except instead of facebook it's youtube and instead of "it took too long to respond, mine says www.youtube.com refused to connect). Pls tell me how to fix it.

If it's like mine, you did it right.

Internet -> Router w/WiFi -> Switch -> wired devices.

All the wired devices can talk among themselves with an exception being if an app uses the internet to talk to other things. But file copies, normal stuff just is traffic on the porst of the devices chatting and the ports on the switch. Nowhere else.

Can create headaches for those that want to monitor what a device talks about.


I have a router in one room of my house and wires running through the house into my bedroom where it's connected to a switch that further connected to several different computers in my room. What I am wanting to know is how the traffic flows from one computer to another. If computer A sends computer B a file does the data travel from A, to the switch, and then to B? Or does the traffic from A to B travel through the switch and all the way to the router and back before going to it's inteded destination computer B? Thanks.


Buy a new one.

It's passed on, this modem is no more, it has ceased to be. It's expired and gone to meet its maker. It's a stiff, bereft of life, it rests in peace. It's kicked the bucket, shuffled off this mortal coil, run down the curtain and joined the choir invisible! This is an ex-modem!

With apologies to Monty Python.

This question needs expansion. Supply some background since the topic is pretty specific to some system not all of us have used.

Me? Yes I worked in cellular design but mostly on the control section of base stations. Hardware design mostly and working with the team that did the actual coding.

I bet that some classroom text book is required to put your post into context. Be sure to add that book title or what class exercise this is from.


Use cdma to construct the aggregate frame for two denders s1 frame 0 , s2 frame 1, the code for s1 is (+1,-1,+1,+1,+1,-1,+1,+1), the code for s2 is (-1,+1,-1,-1,-1,+1,-1,-1)

I tried to solve it but I am not sure.
I multiplied s1 code by -1 and s2 code by +1

and then I added the two codes , and i got this answer : ( -2,+2,-2,-2,-2,+2,-2,-2)
Is this correct?


Not to make it sound bad on your part. "Typical" overreaching antivirus suites.

That is, raise shields, don't pop up and ask if it's OK for the mail app to connect to where with what protocol, IP, port number etc.

I think this is the dumbing down of apps today. Don't scare the users with technical terms. Be silent and just fail.
