Channel 108 5ghz
Had upgrade to 1gb from 250mb. Channel optimisation is selecting 108 all the time for 5ghz. Everything seems to be working fine wirelessly but this is not a UK channel. I know I can turn it off and select a channel but then my upstairs pod goes off.
Channel 108 definitely is a UK channel. UK channels are 36 to 64, 100 to 140. There are all higher channels available for outdoor use with a license.
