I want to a setup where my Raspberry Pi acts as a WiFi repeater, connecting to a WiFi network if available and rebroadcasting it's own network.
In this way, my mobile hotspot could come and go, but the home computers would always be connected to their intranet. That way, the Pi would connect when the phone was in range and the home computers would have internet access without switch networks.
I've got the configuration worked out. In fact, I've already used this setup with my laptop's wireless card (the Atheros QCWB335). Now I'm looking for a usb transceiver that is supported by the Pi and is capable of simultaneous client/AP modes.
The output of
iw list can be used to check for support (look for
managed together under valid interface combinations).
Can the "official" Pi wireless dongle do this? Can anyone verify another adapter with this capability?
