@mitu i'm on 4.7.14 retropie image now. everything is working. if the drivers dont work again when a new upgrade is released, i'll just have to install an older driver again. not a big deal. just glad its working.

@jamrom2 So, I'm not sure how to wipe static IPs from the system. It keeps saying the IP is unknown, as it can't connect.

answer to the f4 command prompts -
iw get reg
global
country 00: DFS-UNSET

You haven't set the WiFi country, as indicated in one of the first replies to your post. Please do so before configuring WiFi - https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md.

After some tries clearing my head i erased the interfaces file (auto lo iface etc...), rebooted and i got connected though ethernet.

Then i installed all the latest versions of everything.

I tried to connect to my WIFI and it dint, BUT it connected to my 5G WIFI!

Now i have internet through WIFI. Its working im not touching anything else!

Thank you!

@mitu Thanks, the backup method worked. Strangely, my psx games were missing in the .img file, but otherwise it worked and it is easy to dump those with RetroArch anyway.

@hairdyeguy said in Is it possible to save multiple wifi networks on retropie?:

Just to be clear, when you said boot partition, you meant the extra "drive" that appears on windows and can be accessed on windows, not the folder inside retropie, right?

Yes, that one.

@mitu thank you for the response, wanted to double check there wasn't anything that could be done retropie side first. I'll reach out to utility board manufacturer.

@soren , that's great that it works! Your post made me think of another post where someone said that they have spent more time installing the Raspberry pi than actually playing on it. It was quite the hassle to make it work but well I guess that's life, what is good usually takes some effort. Again, I am glad it now works for you =)

@hairdyeguy said in Speeding up boot time and the necessary commands:

Tried it along side to disabeling bluetooth and rainbow splash screen + inserting the quiet flag to kernel. Booting time is now 28 seconds!
Are there more things you'd recommend?

The EmulationStation settings I mentioned in my first post - they should speed up dramatically the front-end startup.

Other services that are not strictly needed - raspi-config(?), hciuart (which you don't need if you disabled Bluetooth), rpi-eeprom-update (the Pi zero doesn't have an EEPROM).
You can also disable the swap service (dphys-swapfile) and test, but the Pi 0 has limited memory and swap may be useful if you want to install from source or run other things.

I'm not sure why the dev-mmcblk0p2.device takes so long, maybe the sdcard is not so fast (?).

There may be other - more radical - options

@konrad_ziom Make sure you set-up your Wi-Fi country first before attempting to connect to your AP. Do you see your Wi-Fi in the list of when you try connecting ?

@jet how are you configuring your wifi? are you using wpa_supplicant.conf? if so please show the contents (censoring password etc)

again, please also fill out https://retropie.org.uk/forum/topic/3/read-this-first

@gigo said in Wifi & Samba Share:

I have WebDAV enabled on my NAS, so I assuming it would be a case of just pointing it at the synology.me address I have setup?

Webdav is not the same as CIFS, so the answer would be no. I'd advise against opening your local ROM folder to the internet. If you want to take your Pi on the go, then copy some ROMs locally and use that.

Thanks for the heads up, really appreciate the help. Now for some retro gaming :D

@entozoon please don't. You can edit your first post and make it clear it's a Raspbian issue preferably leaving original text in place for reference) (please don't blank your post as it will mess the thread up). You can't delete the entire topic anyway.

@xxalphawolf420xx From the 2nd screenshot, I see that the WLAN Country hasn't been set. It shows as DFS-UNSET, while on a working system it should show:

root@pie4:/home/pi# iw reg get global country UK: DFS-ETSI (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW (5490 - 5710 @ 160), (N/A, 27), (0 ms), DFS (57000 - 66000 @ 2160), (N/A, 40), (N/A)

The other command screenshot looks like the command's been miss-typed (wlan instead of wlan0).
Check again your wpa_supplicant.conf and make sure it's correct - no extraneous characters, proper newlines, no funny quotes, un-balanced parantheses {/}. Post it here to take a look.

I had issues with Pi4 wifi too. In my case I was noticing it when sending files over Samba from W10 or using FTP, and also scraping problems. I'd get constant disconnects and transfer speeds of around 200kb/s even when it would stay working.

I found mentions online of known issues where noise from the HDMI output can disrupt the wifi signal. Every instance I saw talked about said it was only over a certain resolution (1440 I think), but I decided to try disconnecting my 5" screen anyway, which runs 800x480, and as soon as I did that the speeds went up to around 3-5MB/s and the connection stays stable.

Am I going to have to build the project first?

There are installation instructions (using dkms) on the project page - there's no need for a 'release'.
