Switch from o2 to BE?

lol o2 bought out be* and o2 use exactly same llu exchanges (basically 02 customers they limit the speed with there end using puters) in the bt exchanges if peoples speed are effected by distance from the exchange only differance is you will get a slightly faster top speed i used to have the be pro service and for me was top notch i got about 18meg from distance exchange but that would have dropped had i used 02

so to op sounds like you may have issues of distance on your line if you router keeps crashing out or you could or may have a faulty extension line within your house have you tried just plugging in your router directly into your master socket and leaving it there for 24hrs and seeing if crashes out some router stat info would help see how bad your line is with noise etc. and if is just distance not a faulty extension line moving from 02 to be will not help in any way but need to see info.
