RAXE500 wifi speeds dropped
I've had a RAXE500 for about a year and in the past two weeks the wifi speeds have dropped off. I did not make any changes to the router in the months prior to the speeds dropping off. firmware: ...
Turns out a neighbor has a new device on channel 48 (160MHz wide) that is flooding nearby channels. I moved to channel 112 and speeds returned to normal. I don't really want to use a DFS channel but nobody else is in the higher bandwidth so I'll stick with that for now. Side note: I was also able to get better performance by selecting a channel further away (36) and lowering the throughput (channel width) to 1200Mbps, but it still wasn't as good as just moving to a much higher channel.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Try disabling the following and see:
Armor, Smart Parental Controls or Circle, Traffic Meter.
Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.
Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

Does the router feel hot or extra warm on top?
I pulled the power from the ONT and router and left it off for 15 minutes
-restarted the ONT, connected ethernet directly to it, and measured throughput (530/530Mbps)
-restarted and connected the router to the ONT, measured the router's 1Gbp ethernet throughput (380/530Mbps)
-connected a windows machine (35Mbps/4.5Mbps), mac (20Mbps/3Mbps), and Android phone (20M/4Mbps) to the 5GHz wifi connection.
The router was upgraded to the latest firmware (see OP) then a factory reset performed prior to all of this - I did not restore any router settings.
