I'm using an Edimax EW-7811Un 802.11b/g/n WiFi adaptor on my RPi model B. It works well.
I am doing some coexistence testing that requires me to run the WiFi in the 802.11b/g 2.4GHz band rather than in the 802.11n 5Ghz band.
- How do I discover what channel the Edimax is running on?
- How can I force it to run in 11b/g mode (2.4GHz) rather than 11n (5GHz)?
Note: I don't have admin access to my WiFi router, so queries and configuration must be performed on the RPi, not the router.
