R8000 nighthawk router. I have all 3 channels up. One 2.4 and two 5Ghz . I have had this router for a few years. Recently moved and this is where the problem started. Every few days, one of the 5Ghz channels drop from 200 mbps to 2-3. The channel that drops can be different. Sometimes it’s 5Ghz-1 , other times it’s 5Ghz-2. Our speed cap is 200mbps, so usually it’s running great. Then it will drop. We have nothing near the router either, other than the modem. The only thing that has changed since the move is our modem. We used a 3.0 docsis surfboard, but here in Cali, they run a 3.1. I have went into router settings and changed the channel bands, thinking it was interference from a neighbor, but nothing has changed and I still have problems. Firmware is updated to current release. Any help is appreciated. Thank you

What Firmware version is currently loaded?What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? What is the size of your home? Sq Ft? What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 and 149 to 161 channel on 5Ghz.Any Wifi Neighbors near by? If so, how many? Do you have Armor, SPC or Traffic Meter enabled. How do you have Advanced Wireless Settings configured?

Is is a modem only box or a modem/router that also does wifi and has Ethernet ports on the back? When you moved house, did you reset the R8000? You need to get it to forget any settings that it acquired to work on your old service.

What channels are you using now? What channels are your nieghbours using? Has a factory reset and setup from scratch been performed? iamlemarksman wrote:Firmware is V1.0.4.84Currently has a spectrum modem. ES2251 DOCSIS 3.1.

Whatever they were set at, other than me setting up passwords and naming the channels.To add also, I completely removed one of the 5ghz channels to only have 1 and not 2. This had no effect on the problem, the channel dropped within a few days.Also, restarting the router fixes this whenever it happens. And everything runs beautifully for a few days.Thanks for the help.

It is just a stand alone modem. I will try to get a different number possibly off of it? I never liked the modem/router combos, and I hated renting equipment, which is why I just bought one. Never had problems until now.I never thought about resetting the router. Is that just doing a factory reset and then re-setting it up? I will give that a try.Thanks
