Just thought i'd add my experience to the list of people with this problem i.e. can access Google but not BBC etc.I noticed the problem about 20th April. I'm in Bury, Greater Manchester.I was using a PC still with windows 98 and speedtouch modem. I have now bought a laptop running vista and a Belkin wireless modem router. I have the identical problem on both systems. I've been in contact with Orange Broaadband support many times about this, and they're clueless even though the problems well documented on this website. I found this website yesterday, and thanks to the posts, I've configured the Belkon router to use PPPoE with MTU of 1492 and everything now seems to be working OK. Only problem so far is that I have to reboot the router several times to connect as the username/password authentifiction frequently fails.

That's a worry.
Are you signing on with an @fs id or an @bb?.freeserve.co.uk one. For me if I use the latter method I can only use number 4 - the others don't work (or are probably not meant to work)
I wasn't going to quote these figures assuming the OP had read all the guidelines, for me the 1470 / 37500 gave me a 33% speed increase too - if you read the thread I started yesterday
Having said that my figures today are appalling, but at the time I think it was realistic because I was doing tests one after the other
In my view 1492 is too high, having said that others say that it does work.
When I first tried setting to PPPoE, I thought I'd fixed the problem because i could now get the bbc and Natwest sites that I previously couldn't. However subsequently I found that other sites were still not working. I noticed that the MTU I was using is 1432 - changed it to 1492 and now everything works fine. Speeds good enough for me, so I don't propose to tinker with MTU at the moment. I'm not a networking expert, so I don't fully understand the cause of this problem, or why this fix works. From other posts, seems to be when the IP address ranges change probably as a result of the local exchange going to LLU, and the PPP server MTU changing from 1500 to 1492, causing fragmentation problems which results in dropped packets and TCP waiting forever. If anybody can explain I'd be really grateful
