I ordered this one awhile back and since the update to the main Linux, I am able to use it with no issues.

I think most of the dongles with a Realtek RTL8821CU chipset should work with the latest update.

Seconding this recommendation. Works like a dream.

It works for both Wi-Fi and BT. However, the Wi-Fi transfer is always slow, maxing out at around 4MB/s but usually running slower. Have been wondering if anyone ever sees faster Wi-Fi file xfer speeds with MiSTer?

EDIT: Never mind, I'm dumb. Need to rename "_wpa_supplicant.conf" to "wpa_supplicant.conf" and make sure SSID and password in quotes and not apostrophes (from a previous attempt to get it running). Looks like I'm rolling now.

This one works: https://aliexpress.com/item/1005003037645459.html

I just bought this and the wifi part of this doesn't work on Mister (okay on Win10 PC), it's using a Realtek 8821CU according to the hardware ID. Can anyone confirm the Realtek chip in their 2 in 1? thanks

Same thing is happening to me -> viewtopic.php?t=4776

Did you ever solve it?

I seem to be running into an issue getting WiFi working on mine as well. I ordered the "Ovker" Bluetooth+WiFi one on Amazon, and Windows identifies it as a RTL8821CU as others have gotten working here. Using a USB 2.1 hub (just installed) but only the stock power supply. However, I've only got the dongle hooked up right now, and Bluetooth seems to work with a Wii U Pro Controller. The wifi.sh script fails on "Failed to bring up wlan0". I think I've edited the configuration file correctly with my SSID and password (and changed the country code to US). Is there anything else I'm missing?

EDIT: Never mind, I'm dumb. Need to rename "_wpa_supplicant.conf" to "wpa_supplicant.conf" and make sure SSID and password in quotes and not apostrophes (from a previous attempt to get it running). Looks like I'm rolling now.

EDIT 2: So can a Series X controller pair properly with this dongle? It seems to pair up according to the script, but the controller doesn't respond, continuing to flash it's light instead as if it hadn't paired.

Hmm did the wifi script ever work after you changed wpa_supplicant.conf? I also am getting the "Failed to bring up wlan0" message I changed the wpa_supplicant.conf correctly but no luck.

Most cheap dongles based on realtek suffer by driver quality I fixed problem with mine by replacing realtek driver in mister.

https://github.com/MiSTer-devel/Linux-K ... /issues/39 <- see instructions i posted compiled module for mister.

In case this helps anyone, I am using this USB WiFi/BT module without a single functional issue:

https://www.amazon.com/dp/B07YDFZWT8

It affords both radios in a small form factor and only uses a single USB port.

With regard to speed, it's hard to say what throughput is possible and there are many variables between everyones RF environment and their WiFi network/gear.

Having WiFi is just a bonus that allows me to utilize basic network access without wiring up to my ethernet network when that is not convenient.

When doing large data transfers or when feeling the 'need for speed', I just hook up ethernet.

One option for those who want the absolute fastest speeds over wireless would be to opt for an ethernet to WiFi bridge with the best radio support for your network infrastructure.

What dongle where you using and can I get this fix by using the update scrips?

my wifi dongle no longer works after changing the router password. it just says unable to connect every time. so frustrating. used the script above, deleted wifi from scripts and used update all and it reinstalls but still no luck.

1) what kind of dongle you have?
lsusb output please
2)
you can manually edit /media/fat/linux/wpa_supplicant.conf to make sure your wifi password is right , or invoke
wpa_passphrase YOURSSID yourwifipass > /media/fat/linux/wpa_supplicant.conf
then
execute sync
then reboot

also after that operation please double check /media/fat/linux/wpa_supplicant.conf contents.
it should looks like that:
network={
ssid="ssid"
#psk="password"
psk=44116ea881531996d8a23af58b376d70f196057429c258f529577a26e727ec1b
}
where ssid is your wifi name #psk is password yopu supplied ,psk is yoourpassword encoded

Thanks NineX !
Took the sd card from mister, loaded onto my pc, then i edited wpa_supplicant.conf with notepad. included the router name and password where you mentioned. Saved. put the micro sd card back in the mister. Went to scripts and selected wifi, but still asking for password which doesn't work.

1) picture of dongle not help, connect your mister to ethernet ssh to it , and run lsusb ,then copy output please, multiple wireless chips may exist in same package
2) after if you editing wpa_supplicant.conf by hand , then you should not need to run wifi script it should autoconnect
however as you are doing it on windows/mac
then
network={
ssid="yourssid"
psk="yourpass"
}

for more investigation , or keep your mister hook trough ethernet , or connect to it via usb then find which com port it got assigned and use putty terminal to attach to port then login as root and execute:

lsusb
iwconfig
ifconfig

Hi NineX really appreciate your help

this is my config file
ctrl_interface=/run/wpa_supplicant
update_config=1
country=UK

network={
ssid="router"
psk="password"
}

and i ran lsub and iwconfig - please see screenshot

really appreciate your help

ok , so 2 things.
1) lsmod - need to know which driver is attached to your dongle , because it seems its not one i updated , so maybe i need extend list to update that one too
EDIT it looks like it uses 8188EU driver which is outdated.

2)
please execute:
cat /tmp/messages | grep wpa

EDIT: i'll try to backport driver.
if you already installed patch i provided , please uninstall it for now.
i will provide new bundle of drivers when those will be ready.

Bad news , your dongle will probably not work ,as 8188 driver are woring with max 5.10 kernel...
and i didn't found one that may compile with 5.15 kernel

Thanks Ninex - excuse me for being a bit dumb, but is that because the dongle is obsolete now, what does 5.10 kernel mean? Maybe i should buy a new one any recommendations

i am using TP-link archer t2u nano

kernel is core of the operating system, its being actively developed, so it has versions. mister actually uses kernel version 5.15.
challenge here is that realtek have long tradition of creating drivers for they devices then dump it to community.
as linux kernel evolves , its structure/functions may change ,so old driver without propper maintainer may become obsolete.
last driver i found on github , was abandoned, developer point it will work with max 5.10 version of kernel.

drivers that i updated recently in mister ,have strong userbase ,so someone actively keeps them compatible even with 6.0 kernel...
in post above i pointed one of dongles that actually is in the ist of known to work dongles, and actually utilize drivers i updated.

got this to work finally, i bought a new dongle in the end but the old one i thought had stopped working now works. In the linux folder I had _wpa_supplicant.conf AND wpa_supplicant.conf (one without underscore). I deleted the file with the underscore at the start. And in it changed country code to GB and input the router name and password. Not sure which one or if both did the trick but voila!

ctrl_interface=/run/wpa_supplicant
update_config=1
country=GB

network={
ssid="router"
psk="password"
}

thanks for your help NineX

Hmm did the wifi script ever work after you changed wpa_supplicant.conf? I also am getting the "Failed to bring up wlan0" message I changed the wpa_supplicant.conf correctly but no luck.

Sorry I missed your post, yes, I managed to get it all working correctly.
