In most cases if you have the older modems (100,120) getting the new 250 will improve tha speeds. The engineer tested the cable at mine and the signal or whatever was strong so it was clearly the older modem that was affecting the overall speed.
In quite a few cases the newer modem hasnt helped. I suppose it just helps you find out whether or not the modem is a factor. I get the feeling a lot of people havent rang for an engineer to come out and check the connection.
It is a ball ache to do. Thankfully for me it payed off. If your getting really bad speeds like i was and have the older modems then dont hesistate to get it sorted. The problem is those who have the older modems and are getting 6 or 7 meg. As its supposed to be an up to 10mb service, youd probably get fobbed off. I think mine was a worse case scenario. Also different areas arounfd the uk have different problems. The engineer that i had said they were having problems at the minute, i had to stop myself from saying,"No SH_T!
