Hello, there are some details we need to confirm to do further analysis. 

1. What is the led status of the Archer C6 when it lost wifi connection? Do both wired connections and wireless connections have the same issue?

2. When you lost wireless connection, is it still connected to the wifi but no internet access or it disconnects from wifi totally? 

3. Have you ever tried to change the wireless settings? Including wireless channel and channel width?

Thanks a lot.
