@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.
