@sad_muso said in Pi 4 Retropie issues: Hi, I've just upgraded to a Pi 4 and performed a fresh install of the latest Pi 4 install file (md5: 9154d998cba5219ddf23de46d8845f6c). I know this is still a beta, but I've experienced a couple of quite big issues. Is it the build or something I'm doing? WiFi search initially found about 8 of my SSID name (for some reason). I couldn't connect to any, but now it can't find any SSIDs at all Retropie has crashed on a few occasions (with 'Retropie has crashed' message) Can't change resolution from 4k to 1080p because I can't get into the resolution menu - it just stays at the same menu level Have I somehow got the wrong image or copied it to the SD card incorrectly? I had similar issues WiFi - I created the file pre setup so didn't have this, however did notice a lot of repeats in Bluetooth when setting up my sixaxis for PS3. Didn't get crashing Raspi-config resolution... I couldn't get into this either although I did get a workaround which helped.

@BuZz I write the solution for my case. Maybe it could help someone Pi4 model b access point: TP-LINK RE450 Retropie, any version for some strange reason does not connect to the access point. SOLUTION: I had to install an OPEN-WRT custom firmware on the access point. Once rebooted and configured, everything works. The strange thing, that the first time, with the firmware stock was connected perfectly, then you can not.

@mitu The Bluetooth is down. I could not get my controllers to connect. They would with the usb cable, but not Bluetooth. I think the module might be done.

@Clyde @mitu thank you for the help i really appreciate the feedback and found a solution that seems to be working. For my computer i use a small booster and so i tried putting it on the 2gb_EXT as a test last night, i just woke up and started using and having my phone as a wifi monitor and so far no disconnects.

@MortenHB the 3B model supports only 2.4Ghz Wifi networks, make sure you don't share a 5Ghz SSID on the router. Also, if the Wifi networks aren't separated/isolated through a firewall. Your problem seems purely related to the routersettings/restrictions.

@FlashFlood2864 That's good news. Your welcome. If you get any problems with your wifi connection in the near future, you can try changing the wifi channel in your Router's administration. Being on a wifi channel chosen by your Router is not always feasible and could decrease the wifi's signal if there are too many wifi network's using the same wifi channel. The Router might have a built-in wifi channel tester. :-)

@Otter22 The Wifi is not setup from Emulationstation, but via the RetroPie-Setup. You should have a WiFi menu entry in the RetroPie system in Emulationstation - just like it's described in the Docs.

Hi, did you get my email reply?

something seems off aobut Williamsmith007's reply, should it be flagged as spam?

My problem is fixed, just had to connect to wifi, get things fixed and i'm done! Thanks for da help!

Hi Try setting the clock first. I've had this before where the clock being out by more than about 15 minutes stops the wifi from connecting. Once it has connected once, it is fine on future reboots (even though the clock is reset to default at power on).
