When I first joined o2 I was getting between 14 and 15meg download, I live within two miles of the exchange and just recently my speed has dropped to between 5 and 8 meg download speed.
Went online chat with an o2 advisor who said my router was continually disconnecting, he also said he could find no other problems so a new router would be sent out to me and will arrive in 48hrs, now that service.
Will update this review if the router solves my speed problems.
EDIT: New router arrived, still low speeds.
