I had very similar issues using the OmniTIK PG-5HacD and several SXT G-5HPacD r2 as bridged clients. The SXT radios would connect with very high CCQ. Then slowly the CCQ would degrade and then they would all disconnect and reconnect. I tried changing channels and reducing TX power but it actually made things worse. After many hours over many days I was able to resolve the issue.
Not only did it resolve the issues but the performance is excellent.
OmniTIK PG-5HacD Recommendations:
1- Update to the latest ROS.
2- Increase antenna gain instead of reducing TX power. In my scenario I went from default of 7.5dBi to 9dBi.
3- Be selective with advertised data rates. Example: ht-supported-mcs=mcs-12,mcs-13,mcs-14,mcs-15
4- Use narrower channel widths. Example: channel-width=20/40mhz-Ce
5- Use fewer 802.11 specs. Example: band=5ghz-a/n instead of 5ghz-a/n/ac
6- Use hardware protection mode. Example: hw-protection-mode=rts-cts
7- Use adaptive noise immunity. Example: adaptive-noise-immunity=ap-and-client-mode
SXT G-5HPacD r2 (station-bridge mode)
1- Update to the latest ROS.
2- Increase antenna gain instead of reducing TX power. In my scenario I have 10 SXT radios and I adjusted each one to a different setting. Anywhere from the default of 16dBi to 24dBi.
3- Use narrower channel widths. Match to the AP settings.
4- Use hardware protection mode. Example: hw-protection-mode=rts-cts
5- Use adaptive noise immunity. Example: adaptive-noise-immunity=client-mode
