Model: SXK30B3 / AX1800(https://www.netgear.com/business/wifi/mesh/sxk30b3/)Hardware Version SXR30Firmware Version V4.0.1.100Wireless settings:Region North America2.4G Channel Auto ( 1 )2.4G Mode Up to 574Mb/s5G Channel 149+153+157(P)+1615G Mode When I'm anywhere in my house, including standing right in front of the base station, my 2.5Ghz signal strength is excellent and my 5Ghz signal strength is about 2/5 bars. Speed on 5Ghz suffers accordingly. Thoughts?

what speeds are you getting? What device are you testing on? Have you tried other devices? Or tried a wifi scanner? Have you checked the router vs satellites strength on a scanner?

This could indicate the mobile does not connect to the nearest 5 GHz radio (or has a problem with the 5 GHz radio), the router 5 GHz might be inactive why ever, the backhaul might operate on the 2.4 GHz band, ... Very difficult to guess.

To reiterate, I'm talking about the base station router, no satellites. The signal strength on 5GHz (ie number of bars) is about 50% on a Macbook, Android phone, iPhone and Roku, all of them within a few feet of the router. This is true for each device when no other devices are on the 5GHz band. Speed test on the Macbook for 2.4GHz is ~240Mbps download. Same test, same device is ~67Mbps on 5GHz. No other devices are on the 5GHz band during this test. I have not tried a scanner -- what would I be looking for there? cheers

huh, never even gotten close to 240mbps out of 2.4ghz. I've seen it done in lab conditions but never in real world conditions. Both my RAX200/RAXE500 peak around 120mbps in 2.4ghz. And that's peak. Usually its 50-100mbps on average. curious if maybe you don't have that reversed? what modem/gateway are you connected to? did you try a factory reset and testing with the default configuration? (not loading a backup or changing from default settings on the restore)

(not loading a backup or changing from default settings on the restore) Definitely not reversed. I used this speed test. I'm connected (hard wired) to a Spectrum-provided cable modem. It's a relatively old and barebones modem, but it's obviously the same modem on both WiFi bands. My previous WiFi router (Asus non mesh) didn't have this issue when connected to the same modem. I haven't tried a factory reset; I guess I was hoping for a theory or something that would make it worth the inconvenience. But, yeah, that makes sense to try next.
