I've also noticed that my upstream sync has become stuck on 440kbps. Usualy it fluctuated around 800+
Are there any other problems plusnet are having which haven't been reported which sound like mine?

Think ill stick it out because on the status pages it says there is a problem and they are looking to the vendors of the routers for a fix

Assuming it goes at some point tonight, try measuring the ping results with different size packets (specifically, try 8 bytes, 16 bytes, 64 bytes, 128 bytes, 256 bytes and 512 bytes). I'll do the same.

Quote from: badwolf Out of interest what routers/modems are you using for thse with problems?
Mine's a beat-up old BT Voyager 2100. Convinced it's not the problem, though.
Interestingly my connection stayed fine all last night...
