Since I installed this firmware I have lots of bugs. ( 0.4.0 0.9.1 v0074.0 Build 200701 Beta.71362n)

1- My WiFi speed on 5Ghz dropped from 866 Mbps to 433 Mbps.

2- Parental control sometimes isn't effective . Messenger and whatspp keeps working.

3- Qos on DDwrt device affect my router speed . This ddwrt acess is connected to my router through lan.

4- Blocking devices from online service sometimes is not effective.

5- Blocking youtube mobile isn't working when I add it to blacklist.

- I noticed that you sent this link  ( https://static.tp-link.com/beta/2021/202104/20210414/Archer_VR600V2_210409.zip ) to one of the members. and it is still beta . So should I  replace my firmware with it . Or there are still bugs in it as he stated.

- When will we have stable firmware that support bandwidth control instead of Qos?

- Will we have full range of 5ghz channels instead of being limited to ( 36-40-44-48 )?
