I have an (unprecedented) 730kbps download connection... according to my router. For me this is "ludicrous speed". However...
It has taken my browser the better part of half an hour from opening Firefox to getting this page to load and I am also trying to download Firefox 4 which Firefox is telling me is progressing at the fantastic rate of 535 BYTES per second. Internet Explorer is giving me similar pathetic results.
DNS is resolving near-instantly so it's not that... I set up two (throttled) torrents to test pure IP connectivity and that's working fine as well. I've variously tried turning NAT on and off, the broadband firewall on and off, completely turned off my software firewall / antivirus... safe to say it's nothing at that end.
So what's going on?

This is literally unusable.
Oddly, some sites seem reasonably usable - the Google home page for Firefox (for example) loads up in a blisteringly fast twelve seconds.
If you don't get a reply from me over the weekend, please assume I've lost the will to live after accidentally hitting F5.

Also what does this say for current line speed https://portal.plus.net/my.html?action=data_transfer_speed
Also please post the current router stats - speeds, noise margin and attewnuation.
Normally I would suggest the BT speedtest but with those problems it would take for ever.

For interest, I posted the last message at 12:50 so it took the better part of an hour to post the message!
I hit the "reply" button to your message (after turning "download images" off in the browser) at 2pm and it's just loaded the page... at 14:07.
It's a wired connection to a Bipac router.

I tried a traceroute to cnn.com and it's just timing out after exiting the internal PN network.

Normally I would expect this tracert to go out to level3.net hosts in London and New York but it's timing out at that point.
So something outside my LAN is the issue, but whether or not it's something PN should be addressing or not, I can't say. Obviously, the way the internet is designed, it should be able to cope with this... and if it's an issue States-side, then why is it affecting my ability to use the PN site and community forums?
The clock on my PC has just bounced over to 14:19 so look at the date/time stamp of the message. It should be 14:19 or thereabouts.

This is completely screwed up.
By the way, I'm still waiting for the "https://portal.plus.net/m...ction=data_transfer_speed" page to finish loading. It's so far got to the point where Firefox has identified the page title as "Member Centre" and the certificate for the SSL connection, and is waiting for a reply from portal.plus.net.
In that browser tab the page has been blank for 20 minutes but it hasn't timed out so it has a connection, albeit one that's slower than 9600 baud dialup on a go-slow.
According to the network diags, the WAN interface is downloading about 50 bytes every 2 seconds.
Router diags say:
Quote >> Testing Ethernet LAN connection ... PASS
>> Testing ADSL Synchronization . PASS
>> Testing ATM OAM segment ping ... PASS
>> Testing ATM OAM end to end ping ... PASS
>> Ping Primary Domain Name Server . PASS
>> Ping www.yahoo.com ... PASS
Posting this message at... 14:42 by my clock.

Those suggest that there's a really bad delay between you and PN's edge router. The three areas of concern would be:
- Your ADSL link
- BT's exchange, backhaul, and core IP network
- Plusnet's "central" connection pipe.
There is little you can do about the second item.
The third one you can check - with this URL: http://usertools.plus.net/@gateway/.
You seem to be on "lo0-central2.pcl-ag02.plus.net", so I'm guessing pcl-ag02.
Packet loss can then be seen here: http://www.plus.net/support/service/network_performance/broadband_packets_drop.shtml
If there is a problem, you can try disconnecting, and getting re-allocated to a different pipe.
The first item seems more likely to me... but rather than disconnections, perhaps you are seeing a lot of errors on the line, which are causing delays in sending your packets.
Someone on here had a problem like this in the last few days, where they were getting 200,000 errors per hour - around 95% of their line capacity. They had great problems in getting web pages to finish loading too.
What error figures (CRC, FEC, ES, SES) is your modem reporting? And how are they changing over (say) a 5 minute period?
Using FTTC since 2011. Currently on 80/20 Unlimited Fibre Extra.

I cannot even get usertools.plus.net to load so cannot check ANY of those settings, the speed test won't load. It's taking 10 minutes for the google home page to load (and that's the one with just the search box and search options, NOT the portal page).
I'm literally having to turn images off just to get pages like this to load and even then it is taking in the order of 30 minutes to actually get to a point where it displays the content and I can respond.
The only error I am seeing on the router is "WANIPConnection->GetGenericPortMappingEntry failed" which is to do with port forwarding (which I don't have configured).
I still have no idea why, if I hit Submit on this page, the response is posted up in a matter of a minute or so but it takes 20 minutes for my browser to get round to showing the target page.
Anyone from PN around who's reading this thread.... HELP! I can raise a call from the office tomorrow, but there's no way I can do it from here. Heck, even Windows Live Messenger is unable to track my status because it's so sllllllllllllooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooww

52 seconds to trace the route from a broadband connection to the PN portal is ludicrous but I haven't seen better than this (from home) for over a week!
Now I have disconnected and reconnected the router well over ten times in the past 48 hours and been connecting to different gateways and the latency does appear to be on the PN network.
My router is still saying there's no collisions, no packet loss, no TCP timeouts and no name resolution issues, but does still occasionally fail the PING test to non-PN hosts.
BitTorrent, perversely, is the only thing running on my machine right now that doesn't seem affected in the slightest (although it's still very slow, ~14kB/s download at best with two high-seeded torrents on the go) and that's despite the fact I've set the antivirus/firewall up to treat BT traffic on a set port, to be checked - ports 80 and 443 are currently open and not subjected to the same level of inspection.
I very rarely use BT myself but every now and again it comes in handy for troubleshooting.

Perversely, I just had to log into Yahoo Mail (pinging at 1300ms, wow!) and dig that out from the email because that was more responsive than going to the portal. The PN My Questions page is still loading, while I've been able to read and delete through 4 days' worth of spam.
When I power the router off and on, for about 30 seconds after the DSL connection comes up, everything works okay. Then it just goes rubbish.

I've just done some investigating and your current IP profile is 135k, this has been caused by the number of disconnections as you can see from the graph below. I would firstly have a look at our support pages for dropping connection and if that doesn't help then either raise a fault or call our support center on 08451 400 200
