Ok, here the annoyance (which at this point has gone BEYOND)

I'll be surfing my merry way and either i stumble on to a site, receive a url from a friend or just type in one I visit often (like anandtech.com) and BAM i get the "oh no, i cant' find www.anandtech.com" or whatever. So I site there entering the url and hitting enter again and again and again until it finally goes. This happens both on IE and Firefox.

Can some please enlighten with a solution? Like I said, it started as an annoyance, but now, it's go time!
 
dang it. got carried away with my rant.

DSL connection (4Mbps down, 1Mbps up) and a MS wireless g router (don't ask). The computer is wired though.

I'd have to double check, but I believe I don't have this problem with the laptop.
 
I have no idea *why* (since it should have just not functioned at all from what I can tell), but changing the MTU to 1492 (in the router - down from default 1500) seemed to fix this problem for me.

Or else it was coincidence and I have nooo business being in the tech forum.

Personally I suspect the latter, but wth, you can give it a shot and see if it does anything 😛

Edit: FYI the router was dropping connection with the ISP - although in my case it was unable to reconnect without a router reboot - it worked fine for months at 1500, so I assume that my ISP changed something on their end, but changing the MTU seems to have fixed it (fingers crossed for 1 week now)
 
Might be a bad proxy server on the ISP side of things. Cox.net tried using proxies locally like that in the late 90's and they got overloaded and froze numerous times.
 
try taking the router out of the equation and just connect your computer straight to the net
or is the wireless G one of these combined modem/router thingys?
 
Yeah, it sounds like DNS from the error you described. That could be a sign that 1) your DSL connection is flaky, leading to interrupted DNS lookups, or 2) the ISP's DNS is crappy and sometimes rejects connections. Try a speedtest to make sure your connection is performing as you expect. If that looks OK, I'd say the problem lies with the ISP's DNS - not that their going to do anything about if you complain. I've seen several complaints from people about certain ISP's DNS servers being regularly crappy.

I'll have to try that. Though why would it affect my connection through ethernet and not through wifi ?

I've restarted the router (since I know I haven't for a while) to see if that fixes the issue.

The exact error : "www.anandtech.com could not be found. Please check the name and try again." That was in firefox.

Thanks for the help!
 
I use Sympatico too... same problem... lol 🙂 I just added some different DNS servers to my machine (under properties for the network connection) and it worked fine. I just used the IP of my dedicated server...
 
HA! I found the "problem". When I disabled MAC filtering, not only is everything faster, but I don't get that error.

Is this a trade off with using mac filtering or is my router crap?
