Hello,

 

I'm using armbian 5.25 on OPI Lite and wifi dongle 8192cu, after instaling these drivers:

https://github.com/pvaret/rtl8192cu-fixes

 

I saw that the interface drop half of the packages.... Can someone provide better drivers or tell me how to fix that?

 

wlan1     Link encap:Ethernet  HWaddr 00:13:ef:6b:24:e2
          inet addr:192.168.100.7  Bcast:192.168.100.255  Mask:255.255.255.0
          inet6 addr: fe80::213:efff:fe6b:24e2/64 Scope:Link

          collisions:0 txqueuelen:1000
          RX bytes:3853233 (3.6 MiB)  TX bytes:2734 (2.6 KiB)
 

And not everytime it takes IP ?!?!

Also whatever dongle i use it won't go up automatically and it's necessary to do ifconfig wlan1 down and after that ifconfig wlan1 up

Don't you think providing as much information as possible would be a great idea for others to be able to diagnose your problem? What about 'wlan0'? If it's connected also to 192.168.100.0/24 maybe you already got the culprit.

Sorry my bad.

Driver is installed with dkms and with 2 other types of chips it work fine (mt7601 and rtl8188 and they have 0 droped packages)

 

We have like 20 of these 8192cu dongles and with every single one of them the result is fail.....

 

I remember i had problems with Realtek wifi module before, but it was RTL8192EU. This site help me a lot - Realtek wireless chipset: install the right driver, but it could be outdated. Isn't 8192cu used in Lamobo R1? If so, there have to be working driver in build system.

Where are you from @Nikolai Asparuhov, i am just curious?
