All my wifi device went to unavailable all in one go :(

hi I add two zigbee usb dongles to home assistant one for zigbee2mqtt and the other to zha

both was connected and working but I noticed a lot of my wifi devices going offline and unavailable what am im doing wrong?

ps ive now removed both zigbee dongles and now most of my wifi devices are working in home assistant

my setup is home assistant running on intel nuc 11 gen

a Synology router with a mesh router

Interference maybe, try to change the radio channels :wink:

And use USB extension cables for dongles.

Often posted here, once again

thanks I will try again I was hope zigbee would be easy
