Cudy WR3000E radio1 disabled on reboot

Installing and Using OpenWrt

Hi All,

I just got a Cudy WR3000E and it was seamless setting up as a dumb AP on 24.10.4. The howtos are great. Thanks for all the help so far.

What's troubling is that radio1 (5g radio) comes up disabled every time I either reboot or do a service network restart. I thought it might be dead or misconfigured (still possible!) but what I've found works is clicking the "scan" button in Luci will wake it up, allow it to report local stations, and when exiting the scan it shows active in Luci and might be working (hard to tell). It never does show up in the "Associated Stations" tab, nothing 5g is showing up there, only 2.4g stuff shows up there on the AP (both 2.4g and 5g on the main router).

I have the same SSID for 5g across both router and AP, currently different than 2.4g for testing although I'll put them back to the same once I'm sure all 4 radios work in the devices. I can join the 5g network with my laptop and it seems to work, but I'm not clear which device I'm talking to. My laptop doesn't show up in the main router "Associated Stations" tab (plenty of other 2.4g and 5g stuff there)and as stated nothing 5g is showing up on the AP so I'm assuming it's talking to the AP and just not showing?

I'm sure there is some CLI troubleshooting to be done but I don't even know where to start and any help would be appreciated.

Thanks for the pointer. I did read this and decided to see if that's what was going on. Restarted and gave it a good hour, 5gz radio stayed disabled.

Learned about the "logread" command and found my problem:

Mon Nov  3 10:56:17 2025 daemon.warn hostapd: phy1-ap0: IEEE 802.11 Configured channel (56) or frequency (5280) (secondary_channel=-1) not found from the channel list of the current mode (2) IEEE 802.11a
Mon Nov  3 10:56:17 2025 daemon.warn hostapd: phy1-ap0: IEEE 802.11 Hardware does not support configured channel

I've been unable to get it to work on anything about 52 but on 52 it seems fine. I won't touch it for now, there seems to be no overlap between router and AP.

You have to set country code for 160MHz operation. Default non-country permits only Channel 36(40 44 48 52 56) 80MHz. You can see what is allowed with iw phy

And wait 1-10min for radar detection routines to complete.
