Nikolai Asparuhov Posted February 28, 2017 Share Posted February 28, 2017 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 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 -------->>>>>> RX packets:22255 errors:0 dropped:20602 overruns:0 frame:0 TX packets:22 errors:0 dropped:2 overruns:0 carrier:0 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 Link to comment Share on other sites More sharing options...
tkaiser Posted February 28, 2017 Share Posted February 28, 2017 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. Link to comment Share on other sites More sharing options...

RagnerBG Posted February 28, 2017 Share Posted February 28, 2017 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 This site help me a lot - Realtek wireless chipset: install the right driver, but it could be outdated.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? Link to comment Share on other sites More sharing options...
