Raspberry Pi 3B Wifi Connection Issue From RetroPie

smkinney

I have read through the Forum and looked around elsewhere on the web to no avail. I am a new to Linux and Pi computers so please forgive me if I am stating things incorrectly or asking for help with something thats obvious.

I have the latest and greatest software available, everything installed as per the guides, but my wifi has difficulty connecting intermittently. I know its not my home wifi, or distance to the router etc...It took about 60 tries before it would let me connect at all the first time. Through command line, everything shows up when I scan my lan.but then I go back into retropie and I get the unable to connect to network error when I select my router. Any thoughts?

Thank you in advance!

what is the output of iwconfig ?

smkinney

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

lo no wireless extensions
ether no wireless extensions

please update your system with sudo apt-get update; sudo apt-get dist-upgrade which will then have power management off by default (which should solve the issue)

Or start from a recent RetroPie image.

Just to check what is the output of

uname -a and cat /etc/issue

linux retropie 4.4.11-v7+ #888 SMP Mon May 23 20:10:33 BST 2016 armv71 GNU/Linux

Rasbian GNU/Linux 9 \n \l

odd. power saving should be off by default (did you rewrite the /etc/issue manually - it should be Linux 8 not 9 unless you are not running Raspbian ?

Are you running from a RetroPie image ? We can manually disable power saving (sudo iwconfig wlan0 power off) but I thought the new firmware/kernel had it off by default - perhaps not.

You can do this - https://www.raspberrypi.org/forums/viewtopic.php?p=923081&sid=e0d73509948db593a9a446a2f8bbb2a6#p923081 to force it

I bought a CanaKit, and took the SD card that came with it, formatted everything off. Then I downloaded the latest retropie img from this site and baked it on. thats as far as it goes. I had ran a scan to see if my pi was seeing my network etc, but don't have much linux experience to be changing stuff without hand holding. I don't know if this answers your questions.

@BuZz Should I flash this and start over again? I don't know my linux would be 9. I tried to install Kodi, would that have done it?

Actually it may not be the issue I mentioned as the iwconfig status on power management is often wrong I believe.

What is the output of

dmesg | grep power

it should say

brcmfmac: power management disabled

I would try asking on the raspberrypi.org forums for further help - but there are some existing threads about poor performance with the built in wifi eg https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=138312 - maybe switching your route wifi channel will help also.

Well I appreciate all the help today! Looks as though wifi is holding for now. lol. I will check into those other forums to further my education into all things pi
