I've noticed that after an upgrade to 6.24 I've got a pretty annying packet loss in the WiFi network. They reach up to 20% percent!
I'm testing in parallel from a Linux machine and from another Mikrotik router, connected to the Access Point (RB951G-2HnD).
In the log I see that both wireless clients are loosing packets at the very same time. It's like something is happening on the AP and it stops servicing traffic for a while, than it resumes.
Otherwise the router is reachable from the outside interface, the utilization is pretty low, so it does not seem to be an issue with a router too busy to service wireless requests.
How to troubleshoot this?
I have a server behind the Mikrotik router that I use regularly, and it's kind of annoying as my connecting getts stuck every now and then. And again, the lost packet ration is up to 20%! That's really high!
