Why replace the Billion if its working ok?
I'm not sure it is working as well as it once did. Recently suffered a lot of disconnects and slow or jittery video calls, very frustrating as I'm a working from home.
Have you tried a hard reset and reconfiguring all settings from scratch?
Router has been turned on & off several times when its lost its internet connection , don't want to reconfig from scratch as I have a lot of personal settings that I do not want to lose. Is there any way of recording these so they can be re entered?
