R7000 wifi disconnects (both channels) - 20.2 - freshtomato

Hi - as per the subject my clients on 2.4 and 5 all get random disconnects during the day. I look in the syslog and there is nothing to indicate any issues. Didnt do this on ddwrt so I know its not the clients. I did a full reset and entered settings manually to set this router up. How do I enable/view the wifi part of the logs more verbosely so I can debug whats causing this? Are there any settings to avoid on the r7000 which cause this?

Thanks
