two months ago i bought a raspberry pi during the pi sale so it is not the most recent pi. It during a raspberian update (apt) died with a kernel failure on boot after a month.
So i set it up again with a newer image of the software- i now cannot access the wifi and the thing is not overclock-able anymore according to raspi-config.
I can open wlan0
wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether b8:27:eb:d6:38:28 txqueuelen 1000 (Ethernet)
Do i have a dud unit and how can I check
I do not use wifi (headless) but i would like to know if i will be setting it again sooner rather than later and if losing access to things on the pi is a sign of a defect.
