RPI 3 sees SSID - Doesn't connect

fnkngrv

So I did some searching on this subject, but if it was discussed I missed it. I am running version 3.8 on my Pi3. If I try to connect to my network I can see the SSID along with all the neighbors. When I enter my password (WPA2-Personal, AES) and then submit it sits for a few minutes and then goes back to the networking menu failing to connect. Any ideas?

I have seen a ton of folks say that they aren't seeing the SSID and have to resort to CLI hardcoding, but wanted to know if I would be stuck in the same boat if I am seeing SSIDs?

Did you try rebooting to see if you have internet after a reboot or drop to terminal after configuring to see if it connects? (The error can show even when connection is fine, as it waits a limited time). I increased the delay after 3.8.

I am unable to pull an IP address after entry so I am assuming that the authentication is failing. This is the only device out of dozens with a multitude of chips and adapters that has had this behavior. My router is an Asus RT-AC68R.

you could attempt to set it up manually (if it works, I would be interested in the difference between the configuration generated by retropie-setup - in /etc/wpa_supplicant/wpa_supplicant.conf vs your configuration)

you might get some information from dmesg and cat /var/log/syslog

@fnkngrv I used this site even before I got into RetroPie. https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md

[edit] also you can switch the country for the rpi3 wifi in raspi-config under menu 5 - try setting it to US perhaps (or the same as your router is set to - in case it's on a channel that needs this option changed)

Something i have seen with the pi zeros it could be a power issue. When you get into the wifi setup unplug everything except your keyboard and then try to set it up.

Hi @fnkngrv

It might be worth trying to set the date and time first using:

date --set 2016-07-15
date --set 10:03:00

I remember having something like this when I first got my Pi. My router refused to connect to the Pi the first time unless the clock was within 15 minutes of NTP time. No idea why though, but once it connected once, it was fine and has been working fine since.

I just went through this and for me, the issue was that I do not use a UK keyboard layout and the symbols in my WPA-2 password were not showing up with my usual key presses.

Because the password characters are not shown by default, you may not realize that this is happening, so if you use a different keyboard layout than UK, just make sure you are getting the characters you are intending.

Thank you all for the advice. I will read through the suggestions and do some testing this weekend. I was on travel for work unexpectedly.
