[SOLVED][Feature Request]Wifi Key import via /boot/wifikeyfile.txt

RetroProgramming

I know this one is marked as [SOLVED] but I have an issue with this function.

I tried it with image 4.1.
I created the wifikeyfile.txt with the standard Windows Notepad.
Windows seperates lines by 0x0D 0x0A. This causes a problem.

After importing the file the 0x0D is still attached to the ssid + psk and the connection fails.

I guess there are a lot auf Windows-Users and perhaps it is possible to remove the 0x0D to solve this issue.

@RetroProgramming use notepad++ with Unix line endings

I know what to do, but do you really want to tell every avarage Windows-User to install an extra tool to edit this tiny file?

I will sort it.

Should handle CRLF files now.

Thanks for adding this great feature so we can configure wifi networks without a keyboard! At the moment you can only connect to one wifi network with the script, would it possible to reprogram it to define a number of wifi networks to choose from? I would like this feature as sometimes I want to take my retropie to a friend's house or use the wifi hotspot on my phone and this would save bringing a keyboard along.

Thanks again,
DP

@DP That is beyond the scope of what I think would be useful for most people vs effort to implement. If you want to preconfigure your system for multiple wifi networks you can do so manually by editing /etc/wpa_supplicant/wpa_supplicant.conf and add some additional network blocks.

DP

@BuZz That's fair enough. Thanks for the suggestion, I was able to pre-configure my wifi networks manually although I had to set update_config=0 otherwise the file would get overwritten. It seems like a bit of an oversight that when switching networks it always asks for a psk even if it already provided within wpa_supplicant.conf but it works for my purposes now so I'm happy!

Thanks for your help!

@DP Sorry for being late .... you can modify the bash file I've created in first posting.
This will append wifi settings to wpa_supplicant. The PW will also be hashed btw...

The solution @BuZz created is a fine (to be true finest) way to connect to network. After network is established you can do anything you want.... for example create a bash file by yourself to add more networks and just put it in ES config menu :)

Thanks, looks good now.

For info:
you can use this side to create hashed keys
https://www.wireshark.org/tools/wpa-psk.html

Just enter SSID and PW and it will generate hashed key.
Knowledge is power!

Guys. There is no obvious explanation as to how or where to put this file. I see the scripts an that is it. I am not able to use the pi finder utility. I am trying to manually add the wifikeyfile.txt. How?

herb_fargus

@jseibert81 sure there is. Right in the docs:

jseibert81

@herb_fargus Thank you! I guess mine is not WPA, I will have to get a keyboard. Awesome forum.

herb_fargus

@jseibert81 if you are using wep i would strongly recommend you switch to WPA if you have control over your router . Wep can be cracked in a heartbeat.

I tried to connect my Retropie to my Wi-Fi copying a wifikeyfile.txt in the boot folder using:

ssid="My Wifi"
psk="My Psw"

but it does not work. Any suggestion?

@MEPoss
We'll need more information to help.
Make sure you're using WPA (not WEP) and that your network is not use a Hidden SSID (I'm not sure if that's supported) and make sure that your quotes are exactly " and not “ or ”.
Also I would suggest that you power cycle your wireless router (especially if it has been up for months/years). Which means to unplug the power, count to 10 (wait 10 seconds), then plug it back in and wait for it to boot then try to connect to it again.

Sorry for bringing this up again, but I might have found another issue regarding special characters. My WPA2 passphrase contains a "|" which is (according to the standard) an allowed character. Importing the file gave me an error. I checked wpa_supplicant.conf and noticed that the SSID was imported correctly but the passphrase not. The passphrase was only imported up to the character before the "|". I entered it manually with a keyboard and then it worked.

I would also recommend to implement an automatically deletion of the wifikeyfile.txt after a successful import.

cyperghost

Instead oft using standard Charakters you can try to hash the key. So the key will be transformed to a HEX string that contains only Charakters from 0 to 9 and A to F

Im still on vacation ;D
