Tell me about it! o2 has the highest syn'c rate of any of the providers I have tried if that's any help .. but yeah, i struggle to get 2.7mb sync .. used to be 3.5mb 3 years ago .. (should update my sig really)
I swear the place is cursed for Broadband. When I first moved to Daventry (Lang Farm) 10 years ago, I had to have ISDN as the lines were all TPON or something? When they did finally get ADSL going it was slow, around 1.3 Mbps and even then it couldn't hold onto the connection well.
Then I moved to Middlemore and although faster at 3Mbps , Lang Farm now has FTTC enabled and ready to order...lol, a cruel twist of fate!
