Saw your other thread on the A6 V3, and wondered how you knew it was a bug (and filed a bug report 3 hours after posting) with no configs posted for troubleshooting.
Hey, I just got a TP Link A6 V3 today and I have been having problems with the wifi on this.
I create 5 SSIDs each on 2.4 and 5ghz bands and put these in separate VLANs.
After saving the configuration, SSIDs of 1 random band do not come online. Sometimes, They may come up automatically after a few minutes and sometimes they just never work.
I read some posts here that suggested power cycling it but even after power cycling the AP, They may work once after that but the problem comes back again…
