even if you set a higher tx-power than card supports it will not use that - it will automatically use the max supported power of the wireless cards.
At what times are you monitoring the signal?
When the signal drops - did you send more traffic?
What tool are you using for monitoring the signal?
I assume it as well that the card will default to the hardware Max. But the bad thing that Mikrotik still misleadingly reports what was set manually.
Anytime tried, morning or evening.
No clients are connected to this card while testing. All clients sit on default-5 ssid.
The tool is Homedale
Sporadic gain is one thing when you are constantly monitoring the signal, but what does happen if you monitor a active link to that device? Does it have weird signal dropping as well?
Btw: Have you managed to find any radio specification to that given card? What should these gains be according to the specification and what are the receiver sensitivity numbers?
Here are specifications from FCC test report for this wireless card(PPD-AR5BXB112):
datasheet from the similar card:
Both adapters run in the UNII-3 band in the non-overlapping 20Hz channels!!
I did a few more tests and here are some interesting results.
First I switched the card from 5ghz to 2ghz w/o changing SSID. Testing is done while being connected to default-5. No clients are connected to default-51. You may see this switch in the suden TX increase for default-51:
