No such issues here. Go onto MyBT login page n see if there are any reported issues.
Problem you have with getting another router is obtaining the info to put in the new router as the BT Home Hub 5 comes with your details preinstalled. I can remember my brother ringing his ISP up and they refused to give him the necessary details, dunno what it's like nowadays but just thought I'd mention that.
Or chat to someone at BT and explain your issues you are experiencing, they are pretty good (customer service) from my understanding. 🏼
