Currently i am using a HG533 router connected to a BT Openreach box, and recently the internet connection of any devices attempting to connect to the wifi have been frequently disconnecting after a short period of having a connection, with some devices unable to ever use the internet. I've read through a lot of solutions and have already tried twice to reset the router to its factory settings however to no avail, and there are no other devices near the router that could be interfering with it. I'm not sure whether my router may be the problem, as i undertsand it might be a slightly outdated version. This is becoming rather frustrating so any advice of how to fix this would be grately appreciated.
Thanks
