Whatever you prefer, as with 160MHz you will always use all channels in this band (36-64 or 100-128).
Interesting what will happen if radar is found.

February 27, 2023 at 2:18 pm #22889As an option, you can ‘Auto select channel including DFS channels’ and untick this box, then hopefully no DFS / Radar issues

February 28, 2023 at 1:34 pm #22892I tried 3.0.0.4.388_22525 for a week or so (clean install) plus several reboots but have now gone back to 3.0.0.4.386_49873. I was getting a number of devices on 2.4Ghz (both Wemo switches and Raspberry Pis) that were periodically inaccessible (a restart of the individual device fixed the issues) plus substantial variation in ping times and (some) packet loss which was not there before to devices with good RF signal. This is using the same 2.4Ghz channel (11) on both releases. I also saw on two occasions that after a software reboot of the router node the connection to the cable modem did not go in service (LED stayed red). A power-cycle of the router node fixed the issue, but another restart got me back to the same point (red LED, needing a power-cycle).
Reverting back to 3.0.0.4.386_49873 resolves all of these issues. I typically manually restart this configuration about once a month (just because) however it has been entirely stable for me. (Note: I use Ethernet backhaul, external DHCP/DNS Servers and do not use any of the Parental Control, AIProtection (or similar) features.
I have a router + 2 mesh node system with approx 120 total devices with about 80 of those wireless.

March 11, 2023 at 9:30 pm #229903.0.0.4.388_22525 has been the most stable firmware (for me) since I bought my XT8 about 13 months ago.
Now at about 22 days uptime. Memory usage has been stable. My 60ish connections are all happy. Have manually chosen channels and locked the wireless back haul to 160mhz.
Speedtest from the router at a consistent 580+/23+ (I have 500/20 Spectrum).
For me at least….. FINALLY. Saving this firmware as a future fallback if issues.

I’ve pretty much just ‘set and forget’ in recent months, but this week I’ve had three occasions where the mesh mode has dropped to 2.4GHz and stayed there. A reboot quickly fixes.
I am unsure why it is happening now, but perhaps it’s a radar issue (the logs are huge so I haven’t checked) and maybe just going back to 80MHz is the solution.
Besides that, the XT8 has generally been rock solid for ages and I feel it is now very reliable and dependable. No RAM issues, no USB issues or anything else.

March 11, 2023 at 11:48 pm #22994For me it has now been 25 days on 160MHz with no major issues with the latest 22525 FW, other than having to set 160MHz manually.

March 12, 2023 at 8:54 pm #23010Any ideas if and when UNII-4 will be passed and deployed in the UK for Wi-Fi band?
UK seems to always be too slow when it comes to tech innovation.

March 12, 2023 at 9:18 pm #23011I had this type of chat with ASUS back in Sept 2022.
ASUS will lump UK and EU together with this regulatory requirement and at the time, only US has approved the use of UNII-4 channels.
Alas still no idea when UNII-4 will be approved UK/EU but can touch base with ASUS to see if they have any more upto date news ?
————
5.9G UNII4 is currently only available for US regulations.
XT8, XT9, XT12 and GT6 will also support this.

I think it could solve a lot of the 160MHz backhaul issues if/when implemented.

Radar problems at 160MHz should be eased which will be good for wifi backhaul users, but there will be other concerns around the highest channel in UNII-3 (165) and UNII-4 band channels interference.
Wireless range of UNII-4 is another concern, but generally, UNII-4 should be a positive introduction if UK/EU approve regulation.

March 19, 2023 at 9:25 am #23053Hi guys! Been having trouble with my ATX8 wireless backhaul reverting to 2.4ghz (weak signal). After backreading alot here, may i know if the consensus here to avoid backhaul slowdown is to set 5ghz2 settings to:
hide ssid: yes
wireless mode: ax only
wifi6: enabled
Channel bandwidth: 20/40/80mhz
Control channel: Auto
clicked selected: auto channel including DFS
Is this correct? Yes?
I updated to 22525 a couple weeks back but after a few days, node beacame useless as it reverted to 2.4ghz even if I specifically set backhaul as 5ghz2 on the app. Hope the setup above will cure the common and annying weak signal due to recerting the backhaul from 5ghz2 to 2.4ghz.
thanks in advance!

March 19, 2023 at 9:43 am #23054Welcome, do you mean ASUS ZenWiFi AX – XT8 model ?
Some owners are having issues with their XT8 on wireless backhaul, they have fixed 5ghz 2 – Channel bandwidth: 80 mhz and avoid 160 .
‘clicked selected: auto channel including DFS‘ = not advisable until main issue is resolved.
Hope this helps ?

March 19, 2023 at 11:09 am #23055So sorry for the mix up. Yes, it’s Asus zenwifi AX XT8.
Oh ok, so instead of selecting 20,40,80mhz. I just choose 80mhz only? Also unclick auto channel dfs?thanks a lot! Will try these! More power to you! Great help!
