router: netgear nighthawk X6 r8000
former modem: cm700
new (problem) modem: netgear cm1000
So I did a test on DLSR reports that revealed to me that I had issues with my connection due to the infamous puma chip. I didn't notice much of an issue but I wanted to get a new modem anyways, so I decided to splurge for a nice modem. Upon calling my ISP to activate my modem nothing has been the same. I get random issues with ping spikes in games, people in my house complain all the time due to buffering and connectivity issues. I tried factory resetting the router and updating the firmware and also resetting the modem. No dice. Confused on what to do or what settings I should try to tweak.
Things I've tried:
-replacing ethernet and lan cables
-firmware update on router
-turning off all wireless interference
-checking for wireless neighbor bandwidth leeches on connected devices tab
-calling ISP checking for possible maintenance or outages
Any help would be really appreciated as I am very sad having had a super reliable connection up until now.
