It broke my ct8 as nodes. Hahaha. Had to revert back to previous firmware

Already using the latest firmware, no such issue at all. A stable and good update after so long!

Finally got Tri-band Wireless option with 1 single wireless SSID (2.4, 5-1 and 5-2GHz) when enable Ethernet backhaul option. It have the option to enable DNS over TLS.

After login to the router via web portal, what I do is not using the check for update button, I download the firmware from Asus website then update my Node 2 by manual uploading the firmware, once finish then I off and on the power and let it re-establish the connection with my main node.

After node 2 is up, i manually update my main mode to latest firmware, then once it updated and detect my node 2, I off and on the power to main node let it auto re-connect back to my node 2.

lastly, I power off and on ONT (fibre box) that connected to my main node, and everything is good and do a Speedtest. That all.

I got a pair of CT8 off eBay recently to replace my eero pro units. I installed latest firmware, reset the units twice to be sure I was working from a clean slate. I got them setup and working with wifi backhaul. The web gui seemed a little “glitchy” but thought it was just the nature of the CT8 platform.

Over the past week, I never got the wifi performance I was expecting. Even though the backhaul showed a great connection in the wireless log, I could never get more than about 50m when running speedtest from my two computers plugged into the node unit.

I tried several adjustments and eventually did another reset, left everything default except ssid/password pn the 2.4 and 5-1 bands. The system still seemed flaky and sluggish when navigating the web gui.

Today, I did another reset, installed 3.0.0.4.386.23003, set my ssid/passwords and just let ut run. Wow! Now my setup performs as expected. I can now get 98m of my 100/10 speed on both computers and the web interface is quick and smooth. For now, I am staying with this firmware.

I will be converting them to AP mode later this week and place them behind an Untangle unit I am building so not too worried about security updates.

Hi All, I am still on 23003 due to the many comments here, it looks like a new build of 46122 is out, did anyone try that over 45934?

I am running 46122 on one of my ct8 units. My issue is my second ct8 unit is still on the 23003 firmware and it will not join as a mesh node. It does connect on the 5-2 wifi band but cannot be added as a mesh node. So far, I am unable to access it in order to update it to the latest firmware. For now, I am using one of my ac86u as an ethernet mesh node which works great. I just wish I could utilize my 2nd ct8.

I finally solved this. I backed the firmware on my main ct8 unit down to 23003. Then the node joined the mesh. I then updated to 46122 on the node, then updated back to 46122 on the main unit. I then removed the ac86u from the mesh. Now it looks like everything is working as expected and I can now maintain an ethernet backhaul to the node. In the past it would always fall back to the 5-2 wifi connection. It looks like this latest CT8 firmware is pretty good.

Thanks for the update, let me know how you make out. I am always nervous about ASUS firmware updates, they are hit or miss.

(Also didn't know you can add non CT8s to the mesh, that is cool!)

UPDATE: I was finally able to select the option of Dedicated Ethernet Backhaul and it actually works now!

At this time I am running in that mode with Tri Band Smart Connect and it all actually works as it should.

Kudos to Asus! I think they finally made the CT8 a real operational mesh system. Also, the wifi range on these units are excellent, probably the best I have used so far. But then, they are Qualcomm based and I think work better than the Broadcom based units from the same time period.

Updated to 46122 and did a Reset (hold WPS button while turning on the power) and uploaded my config. So far so good, we'll see what happens.

One node (I have 4 units total, 2 sets) did not want to join the mesh, but I hardwired it and added it that way and it's been fine wirelessly since then.

You negated the reset by Importing your backup config file.
