@Awdeaton , came into to community this morning to ask the same question.  Current firmware isn't as good as the prior version with reliability.

  @dhamiter I noticed exact issue with same firmware upgrade.  I just applied the latest firmware (1.1.3 build 20241115 rel17800) and STILL seeing it.  Frustrating.

  @JBubs that's no fun. Support was able provide an older firmware that was able to work for me. I did update to the newest firmware and I haven't had the issue since. Maybe because I went back to the other one??? However before they provided me the old firmware a temp fix that worked for me (that shouldn't have worked) was changing the security to wpa2. Obviously this wouldn't work for mlo or 6ghz.  One other thing I did that I think helped the most was to log into the modem through a browser and changed the lease time. It seems like it was defaulting to 1 hour, which could be a problem if you have a lot of devices like I have. Since I don't have many new devices frequently I changed the lease time to a week. The industry standard is usually 24 hours. 

  @Awdeaton , all I want to know is when TP-Link will release a newer firmware without the glitched seen in the 1.1.3 release.  I ran the 1.1.4 beta firmware to supply logs back to TP-Link, but I got tired of that release crashing as well.  I dropped back to 1.1.1, and ultmately 1.1.2, and it's been relativly stable for me, and that keeps the peace in my household.

  @408-6G , just wanted to chime in, the newly released 1.1.6 firmware appears to have the issues resolved.  It's not showing on the support website, but it is available for update in the Tether app.

I am having the same issues, Just 2wks in. I thought this was the cadillac of routers, My current firmware is 1.1.6 and still having problems.

I about ready to pack it up and send it back.QUESTION: should all devices be pritorized to one channel? and should MLO be enabled?

Please advise

  @KRAP5 Install the 1.1.7 beta firmware that was just released, I think you'll be pleased.

  @dhamiter Thank you. I'll give it a shot, when I get home.

Is that in the Tether app? Should all cleints be on seperate prioritized channels?

  @KRAP5 , you'll need download the firmware on your computer, extract the the firmware image, the use your web browser to access the GUI interface (either https://192.168.0.1 or https://192.168.1.1).  Once in, click advanced on the top row, then select system in the left column, and then you'll pick firmware update.
