RE220 in High Speed Mode
I’m having problems using a RE220 (AC750 Dual Band) as High Speed mode. It is not working reliably. If I start from a factory reset, it works fine with both the 2.4GHz & 5GHz bands being extended. But I want to operate it in High Speed mode where it connects to my router on 2.4GHz and re-transmits on 5GHz. This does not work.
As soon as I enable high speed mode the 2.4GHZ signal seems to be dropping. When I look on my router (Virgin Media Super Hub 3) I see that the 2.4GHz speed has dropped from 54 Mbps to 4.5 Mbps. On the RE220 are Internet Status changtes to Unknown, and when I attempt to check for a Firmware Upgrade I receive a message "Unable to check for upgrade.
There are no MAC address filter in place. Changing from the default mode to high speed does not change the MAC address seen by the Virgin Media Hub.
I have tried this several times, starting from an hard reset (pressing the RESET button for 1 second). Each time I get the same symptoms when I enable High Speed Mode. The RE220 loses the connection to the internet, and cannot be used as a WiFi extender. I am managing it using a Web Browser (IE or Firefox).
