Computer can't connect to internet

[Shinova]

Not mines, thank goodness, but another computer here lost its ability to connect to the internet after installing the trial version of AVG. It can connect to other computers within the network, but cannot connect to the router's config menu. Which is really weird.

Also it's not the Troj/Cimuz-CD virus, cause I haven't found the file it creates in the system32 directory.


The computer has win xp pro on it. So, any clues?

Did you try rebooting into safe mode?

PS, ahhhhhhhhhhhhhhhhhhhhhhh that never gets old, giving some useless advice back to the community. Ahhhhhhhhh.

Seriously, just turn off the XP firewall and do regular network diagnostics to isolate the connection problem. You know, remove everything till it works then put them back in until it doesn't? With Vista I've had some pretty fucked up network issues, and I've resolved them all largely the same way.

I'm assuming you haven't done this obvious step, because I'm a seething seethe of bitterness.

That's hot.

I haven't tried rebooting into safe mode, but I have tried turning off the xp firewall, and did repair on the local area connection thingy. Didn't do ipconfig /release and /renew cause I think that affects the router as well, I think.

I tried removing AVG as well. Didn't help. Again, it's weird that I can get it to connect to another computer on the network, but not to the router and everything beyond that.

Would you please tell me how the almighty fuck doing ipconfig /release and /renew on the computer is going to affect the router in the slightest? Because they happen to be separate network devices with separate IP addresses (or the router not having an IP, if it's bridged).

The next good question is whether your router is bridged. If it is, you need to configure the correct shit into your TCP/IP settings so you can rech it. If it's not bridged, then about the only thing you can do if ipconfig doesn't work is reset the TCP/IP stack.

The commands you need for that are
ipconfig /flushdns
netsh int ip delete arpcache
netsh int ip reset log.txt
reboot.

You can specify location and filename for log.txt if you enter it there, that version just tosses a log.txt someplace into some default location.

Or you can uninstall AVG and see if that does it.

The bolded command is for XP SP1, for SP2 it is: netsh winsock reset catalog

Hmm, that's useful to know, though the older command also works for SP2 from what I've seen. I've got to take that up with the guys who maintain documentation at work.
