My setup is also stable for 3 days now.  I only use time scheduling under parental control.

For me, the instability on previous 388 fw started after a week.  So, too early to say anything.

You can also check under the logs section I think.  There is a tab for wireless.  Scroll down to 5GHz-2 and see if it stays something like 100/160 or 100/80.

Also check PHY rate.

Backhaul has connected at channel 100 on 80 MHz.

I will factory reset, then force 160 MHz.

Hope the Asus ‘fix’ wasn’t to default to 80 MHz backhaul when 160 MHz is enabled.

Apparently someone tested a beta firmware 9.0.0.4_388_22473 where their backhaul kept dropping to 2.4GHz and not recovering.

Hopefully the issues are related.

Weird thing happened on 388.22068, the last time I set it up.  I intially set it up after factory reset with 160MHz disabled.  All nodes connected to Ch 100/80 MHz.

I then manually changed ‘Wireless Mode’ to AX and re-enabled 160MHz.  The main node had PHY rate 1441 on transmit and receive (80MHz).  The other 2 nodes for some reason connected PHY rates at 160MHz 2882 transmit and receive.  The node in my room was actually giving the same speed on speedtest.net as I would get if the whole network was setup with 160MHz.  It stayed stable to 7+ days.

Always up for a challenge.

Hopefully the ‘Improved AiMesh backhaul stability’ fixes my issue with the setup I have with 3 nodes.

I have updated from 388.22068 to 388.22525 without factory reset yet.  Set wireless backhaul back to 160 MHz as well.

The flashing blue light on the node I believe means the node is not connecting back to the router, even if the app is suggesting all is well ? Give the node a reboot and see if that enables the white LED to return ? Hopefully @Dodgydrains will see this post and advise also ?

Usually the connection is re-established automatically for me.  But a reboot will probably help it along.

When it flashes blue for me, this is when the node had lost wireless backhaul connection and is trying re-establish the connection.

The transmit and receive PHY rate on all 3 nodes are around the full 1441.2Mbps on 80MHz.  Does fluctuate a bit.  On 160MHz it is around double that.  It could be that having the daisy chain multiple nodes reduces real world speed?

 

Via the GUI, max speed I have is 915 down 1,045 up.

My setup is – ISP Router – XT8 router – XT8 Node 1 – XT8 Node 2 – XT8 Node 3

Wireless speedtest from device connected to Node 1 is basically full speed 750Mbps+.  The one in my room is Node 2.  From there I get 490Mbps with 160MHz and 340Mbps with 80MHz.

I will give it a try with 80MHz, in the name of science .  Speedtest has gone down from 490Mbps to 340Mbps.  Lets see what happens.

I do not have the option for 20/40/80 MHz on 5GHz-2.  Mine is 20/40/80/160 MHz.  Am I missing something?  This is on 22068

 

edit.  Worked it out.  Disabled 160MHz now.

I am pretty sure that setting 80MHz on the wireless backhaul and WPA2 with fixed channels will ‘resolve’ most of the issues.  I am on 386.49873 for nearly 2 weeks with my normal settings and 160MHz backhaul, it has been virtually flawless throughout.  It is my go to FW when I encounter issues.

Thanks UK Sentinel, much appreciated.  I am pretty sure ASUS know people have been complaining about this.
