I am totally demented. So I set up a new smart hub 2 on Wednesday (Last one gave up) I switched from the plusnet hub as its just rubbish, phone's wouldn't work well in the bedroom, etc. However after spending ages setting up the bt one to all the smart devices the other day, having great wifi in the rooms, when I returned from work last night the tv was buffering, my son's games were lagging. So today I ran speedtests and have 5mbps-12mbps. I did a factory reset and the first speedtest was back up at 65. Now its back to 5mbps? When I plug in the plusnet router its fine and back up to 65. When I look at the router page it said it had a firmware update yesterday, could this be the problem? I really don't want to have to change back to the plusnet. Im just so frustrated.
