C6250 keeps disconnecting

I recently recieved the Netgear C6250 as a graduation gift for my new apartment. After a tedious set-up period with Xfinity, my internet was set up. Since then I've had multiple disconnecting issues while connected to the wifi. It just drops conncetion and all my devices stop loading and lose connection. A quick restart fixes it, but only for a few hours or so. When more devices get on the wifi it seems to disconnect faster. It's become extremly irriating as I've tried to troubleshoot by changing the 2G and 5G channels to ones by themselves, but that was only a temporary fix. Any solutions will be extremlly helpful as I can barely online game at the moment.
