This morning my internet slowed down to a trickle and is now practically unusable on all of my devices. I spent hours on the phone with my ISP (Comcast) and they did several restarts, diagnostics checks, etc. and ultimately said it was an issue with my router (I plugged my old router in and it seems to be working fine). I didn't totally understand the explanation they gave me but they said to call Netgear and they can tell me how to fix it. I've called the Netgear support line several times and haven't been able to get through (it also seems like I might have to purchase a support plan for them to help me). Any trouble shooting suggestions?

do you have a screen snip of the cable connections page and the modem logs? attach them here. Is it wired devices, wireless devices, or both having issues? Any cable splitters, amplifiers, or attenuators in line? if so, remove them.

Not exactly sure how to find the logs. Hopefully what I attached is right. It’s slow with both WiFi and wired connection. No splitters, etc attached. If I do a reset it will work fine for about 20 mins, then it will slow down again (and the light with the little global starts blinking). If I plug my old modem router in it works fine so I don’t think it’s an ISP issue.

you got one of the right sections but you need more info. it should have the rest of the channels plus the upstream. That's key just as much as the downstream. here's how to get logshttps://kb.netgear.com/30008/How-do-I-obtain-the-event-logs-from-a-NETGEAR-cable-modem-modem-router

Rest of the channels and upstream bonded channels
