Still no go for me, then. The group is netdev, which the pi user is a part of.

As others have pointed out this is most likely a permissions issue.. If the above is not the issue then check which user/group can read/write to /etc/dhcpcd.config by executing the following command in a termal: ls -l /etc/dhcpcd.config The returned output will be in the following format: rwxr-xr-x...

I have also hit the same problem and have yet to find a solution: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=189889&p=1194238#p1194238 Good luck with your problem, if I find something I'll let you know, and if you find something out, I'd appreciate some information, too. Most of the rep...

Try adding a network block to the supplicant config file. Then reboot. BTW, don't hide your SSID on your access point, that doesn't do anything useful. I literally just said I did this in the post above: I added the `ssid` and `psk` to `wpa_supplicant.conf` and ran `sudo wpa_cli reconfigure`. I got...

Again, this is a new flash, and `uname` reports the ...

My file is the same as yours, without `network`, because my wifi interface is mysteriously disabled, which is why I didn't fill it out. Again as stated above, going through https://www.raspb...

I appreciate the replies here, but the responses are fairly basic. Yes, of course I checked the menu bar to see if I could configure my wifi there first. Here's what it shows: http://i.imgur.com/KUeqfxj.jpg It's as though the entire wifi adapter is disabled entirely and that makes no sense. Also, my...

How do I turn on or off the Wifi connectivity on the Pi? I literally just bought this and have flashed the newest OS.

I want this through Wifi, not Ethernet. And yes, that network is up and running.

I'm trying to follow the instructions at https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md. `sudo iwlist wlan0 scan` lists: wlan0 Interface doesn't support scanning : Network is down `ifconfig -a` does show my `wlan0` interface. `uname -a` is 4.9.35-v7+`. `/etc/wpa_sup...
