After months of having dial up speeds in the evening, and their 'tech' support being useless as ever I decided to pack it in. I rang up the cancellation line a few days ago and spoke to some girl (sounded Irish). Told her what was happening and she told me she'd go check with HER tech guys ...
She came back and told me it's a known problem with AOL on the BT network or something and the only fix in place would be to be migrated or moved over to an LLU network or go to their line rental or cancel. There was no date for LLU and no line rental either, if they were I'd still be going anyway. She said she could book a callback from the senior support team there to see if they could resolve the problem. But after months of this problem I couldn't be bothered. I wasn't in any contract so asked for my mac which I should get in the next few days and then I'm off to BT. I googled this problem which brought me here so thought you might want to know.
Good Riddance, AOL.
