Mine was upgraded early hours of tuesday morning and goto say it was a pretty poor start, syncs upto 5024 is best i had but speeds were 360kbs at the best, lots and lots of cutoffs but thats whats meant to happen.
This morning things have seemed to settle down, router is at 4544 / 488 done a few speed tests, i noticed the inc.overheads is on 4054 so not sure if i going to get a tiny increase in speed as yet. For reference bt's tester says i should get between 5-8 meg.
