2.4Ghz stops working in Tp-Link Archer C6U
I am experiencing connection drops on 2.4Ghz, it's not even showing in the devices. Previously also I faced the same issue and I connected to a service center engineer over a call, he recommended some settings which I did, after it starts working but after 2 days again the same issue I started facing. The firmware is also up to date, channel number is 11 and channel width is 40MHz. Please help me to resolve this issue ASAP.
