9.2.0 RPi4 Wi-Fi 5GHz Drops Connection

Zewkin · February 12, 2020 at 9:57 PM

Clean install, no addons. RPi4 4Gb, original power supply, connects to a network, works for 1min, then connection drops and RP4 is not able to reconnect anymore.

The log

Router (ZyXEL Keenetic Ultra II, no 2.4Ghz enabled, only 5GHz) log:

Are you using the RPi internal wifi or an external wifi?

If internal, can you try another wifi - say a USB wifi adapter.

Also can you try ethernet and see if you still get issues.

As a test can you try Raspbian and see if that is stable.

He came from this thread where he said it's OK on Raspbian Buster. I think it's about internal WiFi, because he didn't mentioned an adapter.

Code

echo "options cfg80211 ieee80211_regdom=DE” > /storage/.config/modprobe.d/cfg80211.conf

^ swap "DE" for UK, FR, RU, etc. as required, and see if that makes a difference.

After changing country code to US or DE, RPi still drops connecting every one minute, but then it's able to reconnect and obtain an IP, so there is some progress here, thanks

It's all about onboard WiFi. I also have a Tenda U12 dongle (rtl8812au chipset, 2604:0012) which I use with my PRi2 running Raspbian. I would even prefer to use it instead of the onboard wlan, but unfortunately I did not succeed in making it work with LibreElec, despite it detects the adapter:

Code

[  239.208563] usb 1-1.3: new high-speed USB device number 5 using xhci_hcd
[  239.299361] usb 1-1.3: New USB device found, idVendor=2604, idProduct=0012, bcdDevice= 0.00
[  239.299383] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  239.299399] usb 1-1.3: Product: 802.11n NIC
[  239.299414] usb 1-1.3: Manufacturer: Realtek
[  239.299429] usb 1-1.3: SerialNumber: 123456

...and no wlan1, only onboard wlan0

Tried

Code

LibreELEC:/sys/bus/usb/drivers/rtsx_usb # echo 2604 0012 >new_id

with no results

Try This

first install -> Libreelec Addons/Program Addons/Network Tools

reboot

logon via ssh and test -> iwconfig

wlan0 shows up like -> Power Management:on

then -> nano /storage/.config/autostart.sh

add -> iw wlan0 set power_save off

-> save and exit

-> reboot

logon via ssh and test -> iwconfig

wlan0 shows up like -> Power Management:off

Code

Power Management:off

but nothing has changed, still drops connection every 60 sec

Is your router configured for US or DE, or another country? .. the country setting should be matched to the router.

Zewkin · February 23, 2020 at 2:15 PM

My router's country code was UA, and RPi WiFi completely died after I set UA as PRi country code. It saw no networks, nothing.

Then I got wired and set PL as country code for both router and RPi, and it finally worked! 11n, 40MHz only, 1x1, but it works! Thanks a lot!

Anyway the fact LibreELEC does not support WiFi in Ukraine is weird
