Archer C20i is regularly dropping the 5Ghz Band
Hi,
I'm using an Archer C20i as a Wireless AP (ISP router/modem has wireless disabled) I have separated by SSID's across both bands - so I can choose by device which band to connect to.
Recently updated my firmware and now the router has an annying habit of dropping the 5 Ghz band completely. All connected devices lose their connection, and I can verify the 5Ghz band is missing using wi-fi utility apps. 2.4Ghz activity seems to be stable during this time, and the system log is not showing anything unusual at all.
This issue seems to be occuring once every couple of days, and the reliable fix seems to be a reboot of the router.
I'm convinced this issue is related to the recent firmware upgrade I installed. Anyone had similar problems, any ideas?
