My exchange is LLU ,I'M 1.57 km away ukonline says i can get up to 8MB .
had a chat on their adsl forum they reckon i can get up to about 5MB with the little test we've done,currently on +net up to 2MB Premier but can only get 1MB with a restricted service ie downloading not unlimited!!. 21 .99/mth ,UK Online unlimited so they say!, for 29.99 /mth yearly contract.
Ask for MAC ?
do a bit more research I have a friend that moved to Ukonline and was close to an exchange. he CAN get 5Mbit/sec but due to the quality (or lack thereof) from the end of this road to his house he only gets 2.5Mb-3.3Mb/sec MAX and that changes and regrades all the time. basically if you are going for a faster line make DAMN SURE that you line quality is good enough. From my friends experiance plus net was far more stable.
