YIKES!!! 5GHz Wireless speed has dropped 90%!

Was this happening before you changed to the new LAN switches?

I won't bore you all with the discovery and investigation details, but I am seeing WiFi speed on the 5GHz channel, right next to the the RBS960s AND RBR960, of about 15Mbps-50Mbps on a 2GB/200MB Comcast service! This started all of a sudden last night, with nothing being done to the network prior.

 

- No settings have changed in at least 2-3 days, probably more;

- This happens to multiple devices, iPads, iPhones, Macs

- 6GHz works fine. I can take my iPhone, put it next to any RBR/RBS, and run a speedtest at 6GHz - I get 1400 Mbps. I turn off WiFi 6 on the device, pushing it to 5GHz, and I get 15-50Mbps;

- Direct Wired Ethernet devices (to the 2.5GHz multi-gig switch) are still working fine with proper speeds.

- After trying many troubleshooting ideas without success, I ultimately powered down the entire network in sequence, including the modem - I powered up just the modem and router, and the same thing happens at 5Ghz!

 

There's no way 5GHz could have been turned off or greatly minimized any way, is there? the 5GHz AX setting is still enabled.

 

My configuration:

-NG CM3000 modem -> NG Orbi RBR960 router -> NG XS508M multi-gig switch -> two RBS960 satellites (ie Ethernet backhaul)

- There is also a NG GS348 Gigabit switch connected to the router, which has lower speed devices and unused room outlets on it.

 

Help! What can I try?
