No Wifi Results after using Disconnect/Remove Wifi Config

[columboscoat]

@trigger_death something in here might help. http://unix.stackexchange.com/questions/90778/how-to-bring-up-a-wi-fi-interface-from-a-command-line

[trigger_death]

So sudo iwlist wlan0 scan results in showing the Wifi I intend to use as well as a printer. I'm still not sure how to connect to it but I'm also worried why it's not showing up in the Wifi Menu, does the Disconnect/Remove Wifi Config actually break Wifi through RetroPie?

[columboscoat]

@trigger_death It can do. Go to terminal. Type these commands one after each other following the conclusion. sudo apt-get update then sudo apt-get dist-upgrade. Try that first. If you still have problems please come back to me. Reboot after everything has finished btw!

[trigger_death]

Welp that fixed it! Thank you so much! ^_^

Now I'm wondering. What caused this to happen? If it was what I presumed then is there a proper way to disconnect from Wifi?

[columboscoat]

@trigger_death Stop asking questions and clock GoldenAxe! Some people...

[trigger_death]

Okay actually it's not fixed. I tried to connect to my Wifi network and it failed. When I went back to the Connect to Wifi network the list was empty again. -__-

[columboscoat]

@trigger_death So, you got connected? Briefly?

[trigger_death]

Well connected in the sense that it saw all the available Wifis for a brief moment.

@trigger_death Power down the Pi in the proper manner. Restart your home router while the Pi is off. Keep the router off for at least a minute. Reboot the router.Wait until it sorts its'self out. Re-connect the Pi to the electricity. What happens?

[trigger_death]

The list is still empty.

@trigger_death type iwconfig into the terninal. What is the output. And I mean the Pi terminal...

[trigger_death]

wlan0     IEEE 802.11bgn  ESSID:off/any
          Mode:Managed  Access Point: Not-Associated       Tx-Power=31 dBm
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

lo        no wireless extensions.

eth0      no wireless extensions.

[columboscoat]

@trigger_death your wifi is off. Do you have an ethernet cable and access to your router?

[trigger_death]

Yes and yes.

[columboscoat]

@trigger_death plug it all in and reboot.

[trigger_death]

If you mean connect my Pi to ethernet, it's been on ethernet this entire time.

[columboscoat]

@trigger_death then post iwconfig output again.

[columboscoat]

@trigger_death Ha! Sorry!

[trigger_death]

I didn't notice any differences. Like I said I've been on ethernet since the start. :P

wlan0     IEEE 802.11bgn  ESSID:off/any
          Mode:Managed  Access Point: Not-Associated   Tx-Power=31 dBm

@trigger_death DO YOU HAVE A CUSTOM SETUP? IF NOT PLEASE REFLASH THE IMAGE. IT WILL BE QUICKER THAN MANUALLY CONFIGURING THE CONNNECTIVITY.
