Everything was working just fine until I followed the instructions here .Now the driver seems to be there but for some unknown reason the wireless card cannot connect to any network.

lspci | grep Network

Network controller: Realtek Semiconductor Co., Ltd. RTL8723AE PCIe Wireless Network Adapter

here is the results of running iwconfig


wlan0 IEEE 802.11bgn ESSID:"SSID-E5172-DC7B"
Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated
Tx-Power=20 dBm
Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off

I was thinking ,when I first installed ubuntu 13.04 , ubuntu automatically installed the right network drivers.So,can I make it do that without having to reinstall it again??


i have had the same problem and you can use the terminal and type:

   rfkill list
   lsmod wlan0
   nmap -v -iR 10000 -pN www.google.com

it sould work fine.


Aircrack disables your WiFi card for normal usage. To reenable it, have a look at this question asked on ubuntuforums.org
