After giving up with the slow speeds and constant disconnects I decided to get a new router and a modem to go with it. No more disconnects thankfully but I'm still getting terrible speeds on an evening. It's almost 11pm and I am getting around 8mbps when I should be getting 38. I have tried changing the channels, moving the modem and router to the closest telephone socket to the door. Nothing of that helps.
It's definately not a wireless issue as it was working pretty well earlier in the day but now on all my devices tested I am getting an average of 8 and also getting a lot of packet loss issues.
This is beyond a joke, I've only been a customer for 2 weeks and this has already begun.
