Internet connection slow only on webpages

[vhx]

A friend of mine is having problems with the internet connection, and I went over there to try it myself. Basically what happens is pages are SLOW to load. And by slow I mean it will take 10+ seconds to load a page where it will stay as connecting. Now the first things that come to mind:
- ISP issue.
- Packet Loss
- The website itself.
- Cache is full.

Well for the ISP being slow, that doesn't seem to be the case. Speedtest.net shows a good 9mbps and 500 kbps upload to several locations. Ping is also really low. This seems to rule out any problem where the speeds are being slowed down. Even his download speeds are really high when they actually get there.

I thought, maybe packet loss because I have had similar symptoms with packetloss. I pinged several sites and have even used SmokePing (24 hour line test) that showed 0% packetloss. Ok..

Tried various websites, even places like Google have this problem, so its not site specific.

Cleared cache, use Firefox so tried Internet Explorer and still has the same issue.

I reinstalled his drivers, updated them and still nothing. He has tried direct connecting it to his computer, and also tried using a hub, same issue.

The weird thing is, he doesn't have an issue like this with his parents connection (crappy DSL line). It was slow (like 25k-30k) and that didn't even have the 10+ second delay before even loading google. Also have tried release/renewing the IP, manually setting everything, changing gateway, switching the primary DNS server, etc...

I am truly stumped. I also called the ISP and they said there hasn't been any packetloss to the modem in the past week and that when they ping right now, there is no packetloss and ping isn't high either. At this point I am thinking A) The modem, B) The network card, C) Cables [least likely] or D) The ISP blowing smoke up our...

Any suggestions are highly appreciated.

so you tried directly connected to the modem and are still experiencing this issue? does another computer hooked up to his isp experience it as well?

have you tried booting into safe mode w/ networking to see if the problem persists? try repairing the tcp ip stack using netsh int ip reset reset.log. what is the mtu set at?

Yes tried directly connecting, same issue. We could try another computer sometime i guess.

Haven't tried safe mode yet and will try the repair you suggested. BTW the MTU is at 1500.

Clean is the word.

Run AntiVirus, Anti Spyware, cCleaner, etc.

Then follow this procedure, http://www.ezlan.net/clean#refreshnet

I had this problem once.. my downloads/uploads/ping were perfect, but my web-browsing sucked. It turned out that my primary DNS server IP address was entered incorrectly, so I was using my secondary DNS server to browse the web. It would take awhile for my network to realize that the primary DNS server address wasn't working, hence the delay. Once I entered the correct IP address for the primary, my web browsing was back to what it should be. I'm not saying this will fix your issue, but.. it's one of those things where you might think "oh.. why didn't I think of that?"

*Edit - Heh.. I should have read your post more. You already swapped your primary and secondary DNS =D Maybe they're both incorrect?? Yeah, probably not.
