[solved] rtl8723 wifi connectivity

Hi there,

Has anyone gottent this wifi adapter to function using Arch? It works flawlessly out of the box on Ubuntu, so I know it's possible.

I have followed the instructions on the wiki. My firmware is there. The device is recognized and up, however all attempts at scanning/connecting for available networks are failing. I'm not sure what configuration item I might be missing? 'iw list' does return a slew of infor about the card. I did cursory scan of the ubuntu live cd logs, and everything looks the same (except for the device names), so I must not know what to look for.

Any insight would be appreciated. - Thanks, Greg

From dmesg:

[root@tumble Desktop]# dmesg | grep rtl
[    3.430901] rtl8723ae: Using firmware rtlwifi/rtl8723fw_B.bin
[    3.438130] ieee80211 phy0: Selected rate control algorithm 'rtl_rc'
[    3.441381] rtlwifi: wireless switch is on

From iwconfig:

[root@tumble Desktop]# iwconfig

A cold boot resolved the issue.
