Need help diagnosing connection problem

[CrowK]

Now, this seems pretty strange to me but it's like this

I have 2 PCs, 1 wired to the router, the other wireless
the router in turn is connected to the DSL modem

1 PC (wireless) can connect to the net, games etc at normal speed.

The other (wired, right next to the router and modem) has normal pings to sites, normal latency and no choke etc in games, and normal bandwidth when downloading (2MB), but is very slow when browsing.

For example I get 30ms when I ping a site in the UK, but in a browser it takes maybe 30seconds to open. Also once a page is open, other pages from the same domain, eg pages in this forum, open without delay.

I'm pretty sure it's not my ISP or hardware, as the other PC can browse at normal speed and I've swapped the CAT5e cables from router-PC to modem-router and nothing makes any difference.

Perplexed

What is it like if you plug the wired PC directly into the "modem" ?

Same.

This started up a week ago, nothing changed to make it happen as far as I can tell, no driver changes or programs install just then.

I can still use the net, but it's like there's 30 seconds of lag before a page will respond.

It's one of those niggly problems between trivial and must-fix-immediatly, that I'll probably end up tolerating, but going quietly insane over too.

i take it all the IP settings are set to auto on the wired PC. (was thinking possible DNS issues, maybe)

does your ISP have a secondary DNS server IP that you could try?

Thanks for the reply

The IP address is manually set, but it's been that way for years, the DHCP server functions are off, everything is set to static IP.

My ISP does quote a secondary DNS IP on their support page, how would I use this?

Is there an app I can run to see what services/programs are using which ports etc?

PCs should come with a big red MAKE-IT-WORK-DAMNIT button on the side...

did u manage to rule out the router and connection meathod??

Yes, swapped the wireless card in, disabled the wired connection. Same result.

They did, however, release it as an aftermarket add-on. It's called a "Linux live cd

Unfortunately I lent my "Universal Hardware Adjuster" to a mate

Okay, sorted it out now I think,
I followed the steps on this page and disabled IPv6 requests by firefox and things are back to normal.

Are there any downsides to disabling IPv6 this way? Have I just lost half the internet?

Anyway, I think I'll cancel the keyboard defenestration and have a cup of tea now
