We have problem with wireless
Its Rb800 , 9 clinets connected , all signals in range -65 to -70 , ping all high up to 800 ms to client router
adaptive-noise-immunity=ap-and-client-mode , wireless card is XR5
on same bords is 3 cards CM9 where all working ok , so problem is only on XR5
Router OS is 4.9 , after few minutes upgradeed to 5.0beta2 (new , just downloaded ) and nothing happens.
Then back to OS 3.30 and problem solved , all client on wireless have ping 1-2ms , after downgrade adaptive-noise-immunity set to none ,
but we also set adaptive-noise-immunity to none on version 4.9 and 5.0beta2
Same issue on few locations.

MT Team , what is problem?

i have similar problem but with rb433ah.
4.10: poor CCQ, links unstable...
3.30: perfect!!!

Tried with brand new RB433AH + 3x R2n (ROSv4.10) and no change.

have you solved your problem?

same problem with 4.x and R52 cards. 3.30 solved.
Very terrible exprience! Now I must change version on approximately 30% of routers

Same here using v4.10/4.11 RB433AH + SR71A (2ghz@g-only, 2 chains active).

Same here as two other threads have noted.

PS - 3.30 for all wireless except 900mhz - use 3.28
