Recent firmware for R8500 results in permanent auto channel on 2.4 GHz
After updating to the last couple of firmware updates, e.g 1.0.2.64, 2.4 GHz band doesn't accept the channel selection like 1, 6, or 11. Instead, a wifi scan will show it transmitting something rando...
Discovered a work around recently I wanted to mention. Turning off 20/40 MHz coexistence in the advanced wireless settings while running the 2.4 GHz band in 433 mbps mode will allow the router to broadcast the appropriate selected channel.

Instead, a wifi scan will show it transmitting something random like 4 or 7 as though it was in auto-channel mode, in contradiction to the channel it is set at in the settings. A reset to default settings, and manually inputting the new values, doesn't seem to clear this problem.
As a work around, I've been going back to the beta firmware released around Christmas 2015, which has served well.
Any thoughts? Anyone else with the same issue?
My R8500 is running V1.0.2.64_1.0.62 and I have my 2.4Ghz set to Channel=11 and Mode=Up to 1000 Mbps. inSSIDer 3 (latest free version) shows my R8500 transmitting on channel 11 as expected.
You said you reset to default settings -- Was that a full reset (paper clip in reset hole)? If not, maybe try that. Others have said you really need to do this to prevent prior firmware context from sticking around. I've been lazy and at least restoring from a previous backup after full reset (vs. remembering and re-entering all my settings).
for what it is worth, I dial the 2.4 GHz radio back to 433 mbps setting to avoid the 40 MHz bandwith
Sorry, then I don't know what might be causing your 2.4Ghz channel issues. I didn't do exactly what you described (30-30-30) because I restored from my previous backup after the 2nd reset. In case it helps, I have these defaults changed for wireless settings:
- Wireless 1 = 2.4Ghz = channel 11, Up to 1000Mbps, WPA2-PSK [AES]
- Wireless 2 = 5Ghz-1 = channel 44, Up to 2165 Mbps, WPA2-PSK [AES]
- Wireless 3 = 5Ghz-2 = channel 153, Up to 2165 Mbps, WPA2-PSK [AES]
- Guest Network = unchecked Enable Guest Network for all 3 wireless radios (don't use my R8500 for guest network)
- Advanced Wireless Settings
- checked Enable 20/40Mhz Coexistence for 2.4Ghz
- unchecked Enable Wireless Router Radio for Wireless 5Ghz-1 (don't use this 5Ghz wireless radio)
- Implicit Beamforming is checked
- Airtime Fairness is checked
Thanks for the input. Later tonight I'll try the reset before and after upgrading the firmware to see if it helps.
Believe I narrowed it down to what triggers the phenomena.
After doing two resets before and after a firmware update I changed each setting for 2.4 GHz one at a time.
Changed the channel to 6. No problem. Radio reports channel 6.
Changed the SSID and password. No problem.
Change mode from 1000 mbps to 433 mbps. Problem. Radio reports channels such as 4 or 7 instead of 6 in the settings.
Change mode from 433 mbps to 1000 mbps. No problem. Channel 6 reported correctly.

Good find!
