Before an upgrade: Remember to make backup/export files before an upgrade and save them on another storage device; Make sure the device will not lose power during upgrade process; Device has enough free storage space for all RouterOS packages to be downloaded. What's new in 7.22.1 (2026-Mar-23 16…

I have the exact same problem with SMLight SLZB-06 + 5009 poe. I rolled back to 7.20.8 and it works fine now. I also had all my WAP AC access points fail on my CRS328-24P-4S+RM switches when I was using 7.22.1. Rolling back to 7.20.8 solved the problem.

I agree about the open ended remark, but as this is pure an experience issue I want to check other users, if they experience the same Thing with DNS : it resolves correct, but if the performance is low it seems as if you have a saturated internet connection I cannot give details about performance …

I understand your point. However, describing the issue as "less performant then before" is quite subjective and difficult to act on. The cause could be anything - for example, a slow upstream DNS service - and it might simply be a coincidence that it was noticed after the upgrade. It could just as w…

All I have installed is routeros, and wifi-qcom-ac. On the v7.20.8 there is 228KiB free space, but on the 7.22.1 barely 20KiB. So I am going to disagree with your comment, and say this is package sizes for a normal setup that isn’t fitting in the allocated space anymore. I could not alter any confi…

@phille05 Do you have Queue setup on WAN interface (Simple or Tree)? Due to issues reported here and here I had to revert to 7.21.3 because packets was not queued and it was causing high latency which was also affecting DNS resolving.

Go to https://speed.cloudflare.com/ and check latency. In my case it was very high +500ms (poor LTE strength) for upload which was affecting requests, DNS especially. With working Queue Tree on WAN interface I have <100ms. When you don’t have custom Queue setup on interface, default queue is applied…

in IP/DNS settings I disabled the forwarder and added a google dns server IP in the “servers” list a dns lookup is faster now, also if I visit an unvisisted site it starts loading immediate, with forwarder active it seems to pause a ultra small time

Hey Guys, I have a strange issue where I can’t add new containers in this release. The Shm Size field is pre-filled with “64 MiB”, however when I go to add a new container, this field is red and won’t let you apply new changes. This is running on a CHR cloud version. Not sure what to change the S…

This issue should be resolved in Winbox 4.

V7.22.1 [stable] is released!
