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.


Now it's starting to sound like the overreaching antivirus suite. I can't fix that. You or the antivirus folk have to tell you.

Again, no mention of the mail server so I can't check if the telnet check should work. I have to leave you to know this.

The final error message on your reply could be correct on both machines (as in fail) if the email server is imap or the DNS didn't resolve the server to an IP address.

Did you ping the server to see if the name resolved? Does the ping work the same on both machines?


Sorry it just fails on pc with problem,

421 Cannot connect to SMTP server, connect error 10060

I figured avast was causing the issue, and found an article that suggests to clear ports from redirect settings of avast. But after doing telnet fails to connect to server with following message.

could not open connection to host on port 25.


So this fails on both?

Anyhow, since you didn't share the email server or host I can't doublecheck or supply how it should work or if there might be a DNS issue.

DNS? Did you try it with the DNS you use? Or the Google DNS of

Remember I might assume you know that telnet test is for SMTP and not IMAP servers. That was noted in the articles I read from my link.


So I have a little vague question and I don't know what to even google to get right answer.

I am trying to setup email client on friend's computer remotely. I tried outlook, native windows 10 client and thunderbird, they all fail to connect server in anyway with all settings. While when I try any client on my PC, just basic settings like mail server, id, password work fine and after that I am able to retrieve configuration data. So what could be causing this behavior? Any steps to fix this or troubleshoot? Any help will be great.

Thank you.


Hello! I just downloaded a program called FBCIM. That is: "Facebook Chat IM". It doesn't function. It says it's still under development. Now I would like to get in touch with the developers of the program. How can I achieve that? Please help.
