Hi,
I recently recieved my new Talk Talk router, set it up a few days ago. but my speeds have dropped by roughly 10mbs, from 32mbs to 22mbs, its set up properly, i have reconnected the old hub and tested the speeds and it went back up, reconnected the new talk talk router again and the speed drops again. the speed currently fluctuates between 20mbs and 25mbs. 
Any help with this issue would be great, thanks.
