Help! Really strange WiFi problem.

(1/4) > >>

Deozaan:
Hi everyone,

I just started having an issue yesterday that I can't figure out.

Basically, I can use the internet just fine for about 10 seconds. A page will load, I can ping any servers and get a reply, etc. But then after I load a page or two I can no longer load any websites and I cannot ping any servers. But the strange thing is that my IM programs still connect and my download manager will still download. So I know I have a connection to the internet, but somehow all traffic to my browser (and ping, etc) is being blocked.

The other strange thing about it is that all the other computers on the network work fine and have no issues.

If I go to the command prompt and type "ipconfig /release" followed by "ipconfig /renew" then the process starts over. I can ping and visit a website or two but then suddenly all pings timeout and no websites can be loaded.

HALP! :'(

mouser:
it sounds to my novice ears like your problem is with the nameservers you are connecting to.

if you find that you can ping websites by their ip address but not by their domain name.. then that would pretty much confirm it.

steeladept:
If mouser's suggestions don't work out, maybe your ISP is having issues on port 80?  Issues on a single port are very rare, but do happen - almost exclusively due to a misconfiguration somewhere. Try something simple.  If you know of an https site you can hit, see if that works.  They run on a different port and that may stay on constant.  Another option would be to try an FTP.  That runs on port 21 if I remember correctly.  BTW:  DON'T LOGIN to anything you test in case it is something else!

How would I find out the IP address?

Deozaan:
I pinged it on my computer that isn't having problems and then pinged the same IP on the PC with the problems. It all timed out.

Also, https didn't load, and ftp doesn't work either. But my download manager is still chugging along (though sometimes even that stops as well).

EDIT: Here's an interesting thing, though:

The netbook which can succesfully ping resolves www.yahoo.com as www.yahoo.com [67.195.145.138] but my PC with problems resolves www.yahoo.com as any-fp.wa1.b.yahoo.com [67.195.145.138]

So it's the same IP address but the domain name is wrong. Is it a virus/trojan?

EDIT: I tried a few other domains (like donationcoder.com) and they all have the same name on both PCs.
