Re: if any of them actually provided a decent service
When I moved from BT Infinity to AAISP my speed went from 27Mbps to 29Mbps.
Browsing wise I havn't noticed any difference, but Torrents hit a lot higher speeds now.
Although people slag off the BT Homehub, I'm convinced it had better wireless connection that the Thompson TG585 that AAISP give you. But it works good enough so haven't changed it.
