I am trying to set up rtl8723bs SDIO wi-Fi card on 3.17.2 kernel. I've compile and install driver like here.

grep -i cfg8 .config CONFIG_CFG80211=y # CONFIG_CFG80211_DEVELOPER_WARNINGS is not set # CONFIG_CFG80211_REG_DEBUG is not set # CONFIG_CFG80211_CERTIFICATION_ONUS is not set CONFIG_CFG80211_DEFAULT_PS=y CONFIG_CFG80211_DEBUGFS=y # CONFIG_CFG80211_INTERNAL_REGDB is not set CONFIG_CFG80211_WEXT=y

I am using fresh ubuntu kernel config from here. I've disable some unused options...

I see no errors in dmesg from inserted wi-fi driver. Also I see wlan0 interface in the system with ip link command. I can set up the interface but seems that it doesn't support Wi-Fi cause I can't see any phy device with iw list.

rfkill say nothing. It is a VOYO a1 mini tablet and seems that it has no harware Wi-Fi lock button.

I can't understand what I am doing wrong((

  • The easiest way I've found to install Ubuntu on devices with the RTL8723bs is by using Ian Morrison's shellscript after installation of 14.04 LTS. Info is here: plus.google.com/+IanMORRISON/posts/UNWdwRMqy3j – Tarjei S. T. Sep 4 '15 at 6:19
  • On that that time there are no way to run rtl8723bs Wi-Fi in i386 environment. I don't have any troubles with x86_64 kernel.... – user2986553 Sep 10 '15 at 7:41

Seems that main problem was in disabled hardware counters( Intel remove them from kernel). Without those system was unstable.
