From what i have read other people say about BT. They talk about how they get a slow speed after using P2P networks the reason for this is because they are really heavy uses and BT restricts there bandwidth so that it doesn't other BT uses. 

My own experience is that they have been great from the start years ago before wireless routes we got a free router with a USB and Ethernet which was unusally at that time

Then when wireless started becoming the norm they sent us another free  router with wireless.Then most recently they have sent us a free hub and a free hub phone.i will say that that getting the free routes tied us into another 12 month contract but as we have stayed with them so long not been a problem. 

Only have 2 problem in the years we have had. the first was fixed that day the second was the next day.

some mention the price but you do get alot more than some others off like 500 free wifi mintues at hotspots and with the bt home hub free calls over the internet and really cheap call to over seas
