I have a ring presenter from Genius, but the usb receiver was lost. The support said they dont have the receiver as a spare part. Is there a way to use another receiver or sync the device?
You can buy same frequency as your wifi receiver was operating. 2.4GHz was the frequency so try to find the receiver with same spec and sync it. But not sure whether it can able to match as the original one. But need to quite careful while selecting new one need to match all the specs as per your lost receiver.
If the suggest idea in the post 2 doesn't worked out means purchase a pair of Wifi transmitter and receiver with the same make and specifications. Replace with the old ones this will solve your problem.
I tried the a wifi receiver at the same frequency, but it does not detect the presenter. I guess there is some unique code. I'll try to find a pair of wifi transmitter and receiver.
