Internet not working on main comp but works on laptop.

[iq2da]

Hey.. I am having a problem. When I boot up my main computer which has my modem and wireless router connected to it my internet sometimes works on start for a few minutes but then stops working. (Still tells me my connection is fine). When it stops working on my main computer, my laptop can still connect to the wireless network and it works fine. (Which is how I am posting this thread right now).

Anyway, if I try repairing the connection it won't allow me. I've tried using a static ip. Doesn't work either. I saw another thread on here where someone was having something of the same problem. He thought it was his onboard LAN giving problems. I am just curious as to why it works sometimes right on start up and then just suddenly stops. Should I just buy a new network card or is this solvable? Anyone?

You have modem and router, both connected to the "main computer"?
You connect the router to the modem? And the computer to the router?
How do you connect your "main computer" to the modem or router? You use a network cable?
Through which equipment you are connected to internet?

Yes Viking. Modem to router. Router to main computer using an ethernet cord. I've even tried going directly from the modem to the computer. Still doesn't work. Another thing is now that my computer is freezing during shutdown. I'm not sure if there's some sort of issue going on with my onboard lan. I tried uninstalling then reinstalling the driver and it just says that it is working correctly like before. I've even tried disabling the device in the device manager and it freezes everytime. I have no idea what's going on.

I did that. It started working on the restart for about a minute. But then in stopped again. I don't know what the *censored* is going on. Could it be a virus of some sort?

Installed both of them. Still no luck. What do you suggest next?

I suspect, your network card is shot.

There could be many reasons for that kind of malfunctioning.
When you are connected by wire to the router, please create a file with the ip settings of your computers (the one with the problem connected through wire, the one with wireless connection - that still works - leave it connected through wireless).
On each computer: start->run->(write now) ipconfig (space) /all (space) >c:\ipcfg.txt
Paste here the contents of the ipcfg.txt files (c:\ipcfg.txt)

Thanks guys. I'm gonna go buy a network card today and see if it works. If it does, then I'm guessing it would be safe to assume that my onboard LAN is messed up right?

Hey guys. I went to buy a cheap network card today, installed it, and internet is working perfectly. No cut outs, nothing. So I guess you were right Broni. Thank you for all the help. It was much appreciated.

You're welcome
We try to fix things around here, as much, as possible, but sometimes, there is no other choice but to spend couple of bucks.

Ya, it was only $16 and change. Anyway, what could have caused it to suddenly stop working like that? Any idea?

[Broni]

Computer parts JUST do this. Like any part of any mechanism.

Wow. So this is weird. I backed up my entire system and decided to reformat my system drive and reinstall windows. Just because my system wasn't running as fast as it used to. It turns out, I re-enable my onboard LAN in the BIOS and plug the ethernet cable into the onboard, and voila! Internet is working perfectly! lololol. So now I am going to return the network card I bought. This is crazy. I'm assuming it must have been a virus maybe? I am going to purchase some software for that. What is the best or some of the best software out for that? The biggest names i've heard are symantec norton antivirus.. and mccafee any idea what i should get?
