upgrading from V3.30 to V5.14 Disconnect issue

RouterOS Wireless Networking
1

Hey everyone, I’ve been experiencing some issues when upgrading some Rb433/433AH from V3.30 to V5.14. The 2.4Ghz links become unstable . 2.4Ghz-10 Mk-Mk links disconnect cyclically, with a reset rate directly associated with the troughpout demand, and the 2Ghz-B PtmP links don’t last 10 seconds for the worst cases. all cards are r52/r52h. the 5Ghz links remain unaffected ( XR5/R52h). the 5.14 version also looks incompatible with a CM10 card running at 2.4G. we got to downgrade the whole network to v3.30 again, and things got back to normal. What could be happening here?

Thanks for all
best regards from Brazil (y)

I have similar issues. 5.11 seems to be the better of the v5, 4.17 for v4. 5GHz links seem completely unaffected, 2.4GHz running smaller G or N only channels (or downconverted to 900MHz) work fine. Any time B mode has a shot in the link, I have various, random issues. It seems to work fine until I turn off my laptop and decide to relax, then the phone calls start coming in.
