Blackberry Key2 LE vs. FRITZ!WLAN Repeater 310 with FritzOS 7.01

Alexander Bochmann Friday 25 of January, 2019
Last night, my 2.4GHz FRITZ!WLAN Repeater 310 upgraded to the new FritzOS release 7.01. The repeater is configured as FRITZ Mesh device (connected to a FRITZ!Box 7490 as mesh master). I'm currently tinkering with a Blackberry Key2 LE that I bought to replace the aging S4 mini that I used up to now (more on that later, maybe). After upgrading the repeater, the Key2 LE couldn't connect to the wifi network anymore. In an area only covered by the repeater, it didn't even see the SSID anymore. It was still possible to connect directly to the base station though, when moving into range. All the other devices I had available had no problems connecting through the repeater either.

As AVM doesn't currently provide downgrade images for the Repeater 310, I tried a factory reset and re-establishing the mesh connection, to no avail.

I then started playing with wifi network settings, and as it turns out, there's a simple fix: Don't use channel 13 on the repeater.

After excluding channels 12 and 13 from the wifi channel selection on the FRITZ!Box, the system switched down to channel 11, and suddenly the network appeard back in view on the Blackberry device. Also tried manually setting channel 6, which worked too.

Not sure what to make of that. Channel 13 was fine with this device before the FritzOS upgrade (yes, I know using it is not recommended, but this is the first time that created a problem for me).
