No WiFi with PiTFT 2.8 Touchscreen

Post by dlittle55 »

I have a Raspberry Pi 2 with Raspbian Wheezy. After downloading and installing the Adafruit TFT-Helper, I got the PiTFT 2.8 screen (#1983) to work OK. The Edimax WiFi was working prior (did the download while on WiFi), but after installing the PiTFT and rebooting, the Edimax blinks like it's trying to work, but never connects to the WiFi (when checking ifconfig, never gets an IP address). I tried the ifdown and ifup --force commands and it returns "Operation not permitted" and "Invalid argument"

Any suggestions or ideas would be greatly appreciated, thanks!

You need to use `sudo ifdown` and `sudo ifup`.

As a basic hardware check, what do you get from `lsusb`?
