Well, as @blkt and I discussed, or rather @blkt pointed something out to me when I mentioned a change since today's release, the 1900s are not the 3200, they have different wifi chips, firmware blobs, etc. but the driver is the driver. SO, trying to make two different chips act the same exact way may not work right. So, this is an issue with whatever BrainSlayer was trying to accomplish with whatever hidden change in the driver_repository repo that is not public. Next release may offer some improvement, or not, who knows until it hits the streets.

So I kept wmm disabled and changed to G only. Left all else unchanged.
Wifi for the past 2 days has been up and down on 2.4ghz again showing same errors as before.
I re enabled wmm applied and rebooted and disabled... rebooted just to be sure. Same problem.

Put router in NG mixed and it seems ok again.
Speed tests on 2.4 are about 25mb.
But I'm not sure how to see what band I'm connecting as... N or G.

5GHz seems solid. I have wmm enabled on that.

Confused as I though G was what was solving the issue.

Be sure to reboot after saving a change instead of the apply button.

Disabling WMM will drop you down to 54 Mbit data rates, 802.11g speeds.

Which wireless network mode worked for you initially with WMM disabled? Mixed? NG-Mixed should be fine too.

Did some further testing the past few days.
Replaced my remote 1900 with a EX7000 Extender. Seemed to work fairly well, but one cam V380 would not connect or if it did only for a short period. Also it seemed that the 2.4Ghz problems got moved to the AP with hundreds of entries, as below.
2020-03-01T12:52:06-06:00 205.200.23.81 kernel [ 784.194679] ieee80211 phy1: Mac80211 start BA 02:0f:b5:4d:bc:98
Never had this with the 1900 in Client mode. The AP was always clean.
Today returned the 1900 to it's place in the barn. Initially tried with wmm enabled and N/G Mixed. Router started random reboots after about an hour. Switched to Mixed and router now reasonably stable, just my V380 randomly resets but does re-connect. I never did like the V380 cam anyway so it is not an issue.
I will be watching for the 24hr check tomorrow as this was causing a reboot with wmm enabled. I did upgrade most routers to r42557 and removed all 2.4Ghz from my 3200's
Will also report on stability of the sytem as time passes.

Wmm disabled and NG mixed is the only setting that seems to keep 2.4ghz working for me.
Setting to wmm disabled and G only causes issues. Why would this not work but NG mixed appears fine?
