Wifi Unable to Connect

Mayday10

I have just opened up the awesome world and possibilities of this system. I love the support and tutorials. Everyone who has contributed to this project deserve Nobel Prizes. I have run into a problem. I have searched these forums and also the "wiki" for a solution and have not had any luck.

I have a Raspberry Pi Model (Rpi3) Model B
Retropie Version 4.1
Built from SDcard image from the website
I have a keyboard and an NES 30 8Bitdo Bluetooth NES Classic controller

I attempt to connect to wifi.
Using the menu on the Emulation Station, I "Connect to Wifi Network", my network is listed. I select the network, put in the password, I wait while it says "connecting....", then after a minute, I get an error that reads "unable to connect to network". The password is completely alphanumeric, 12 characters.

I have also tried the "Method 2" in this guide https://github.com/retropie/retropie-setup/wiki/Wifi for WEP... and also tried the WPA/WPA2 script. Neither has successfully connected me to the network after a reboot. These are under "sudo nano /etc/network/interfaces"

I did connect the Pi up to the ethernet directly and I had connectivity. However, the unit will be used in a separate room than that.

I do not believe the router is too far away. It is actually fairly close, on the same floor 2 rooms away. I also attempted to connect in the same room, within 5 feet and it still failed.

It is a medialink Wireless-N Broadband Router, Model Number MWN-WAPR150N

Thank you, and I hope I respected Forum protocol. I will check this often if more information is required.

From a terminal, please type sudo cat /etc/wpa_supplicant/wpa_supplicant.conf and make sure the password is correct.

Did you try rebooting after it said it failed to connect? - the wifi package wait a set length of time and it's possible it will connect but it will take longer.

Check the output of ifconfig after a reboot and waiting 5 mins.

Please can you post the output of cat /var/log/syslog after rebooting and making sure the wifi configuration is correct above, and after waiting 5 mins. Please post it on a external pastebin site as it may be a large log.

@BuZz
please forgive my noobishness. This type of platform and these commands are new to me. I am pretty incapable at this point of looking at the code and analyzing what is off.

I typed that first string in, and the password is correct

I have tried to connect, then reboot and it still does not connect. Also, like I said, I have tried that "Method 2"

I tried iconfig too

I tried to show ip address
alt text

I ran the cat /var/log/syslog and yes, the output was quite enormous. I am not sure how to copy the text though from the raspberry 3 for display

Thank you1

Did you manually set it to WEP? Please reconfigure via the gui and repeat the commands. To get logs check the ssh page on the wiki.

If you changed the interfaces file please put that back also.

I would black out the password BTW - unless you already changed it for getting this to work.

I attempted with the interfaces and it did not work. I restored to the original.

I am sorry, i dont understand: What does "Please reconfigure via the gui and repeat the commands. " entail?
Thank you again for attempting to help.

You said you followed the manual instructions so I wanted to see the output of the commands I wrote above after configuring via the wifi config tool as it shouldn't have detected your network as WEP, and you said you had put that in manually.

These commands - after reconfiguring wifi via retropie-setup:

From a terminal, please type sudo cat /etc/wpa_supplicant/wpa_supplicant.conf and make sure the password is correct.

Did you try rebooting after it said it failed to connect? - the wifi package wait a set length of time and it's possible it will connect but it will take longer.

Woo hoo.

I fixed the problem

I went into my router and changed the password. Made it 8 lower case characters, and put it in the WPA/WPA2 row. Connected through the easy retropie method 1.

Hi Mayday10 I haver the same issue , was unable to connect to my box using WIFi , my security key is 18 characters, I don't know if this is supported by the Rretopie V4.1 also !!

I will try this soon an get you inform if your solution fixed my problem.

Thanks for your help

Tip: Do NOT have "@" in the password.

Even if it makes a zombie thread alive now :)
Hash your password! Then you can use any character
Use the guide I wrote in the posting
