Does the SOLO Slingbox support Remotecontrol functions for CanalDigital KAON PVR-N550
I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/thread/3300?tstart=0
Come back if it that doesn't help either.
Is it possible to use a WIFI USB dongle for connecting to a wireless router ???
No, Unfortunately the USB connector on the back of the Solo is not connected to anything useful. It's only for testing purposes
