Looks great! So it’s the FragAttacks fixes plus the other bugfixes mentioned in 28.1, without being on a beta.

Anyone applied this yet? Looks to fix some pretty serious vulnerabilities!

Interesting: I'm completely unable to find anything newer than 28.1

I've been applying 28.1, but WiFi5 wave1 APs only update to 26.8.1 for that version, even thought both 28.1 and 27.7 include the security updates...

I've got it applied on my MR33 home setup with no problems experienced but that's a very small sample size!

 

Got a bunch of MR45 & 46's I'll be throwing this out to in a few weeks time

  • Wi-Fi 6 MRs might exhibit unexpected reboots (Wi-Fi 6 MRs)
FYI there is a 27.7.1 now, fixing the above issue. I hit this pretty badly on my MR46 and MR56, where once or twice a day, both would reboot at the exact same time.

Ye I went to push this to some MR46s this time last week, luckily decided to do a once over of the release notes and saw the emergency notice about the reboots so bailed out!

 

Glad a fix got pushed out relatively quickly but a bit disappointed something like that wouldn't be caught in QA to be honest given it's the release candidate not beta
