    A possible solution given that other Realtek WiFi chips and Linux 3.8.x won't work together:

    Before trying the proprietary driver right away, please try something with the native driver first.

                        Frequency:2.437 GHz (Channel 6)
                        ....
                        IE: WPA Version 1
                            Group Cipher : TKIP
    Please try changing the channel to 1 or 11, as well as encryption type to WPA2-PSK with AES (no TKIP !) in the router. After saving the settings, reboot the router to be sure that the settings take effect.

    With the above changes (or without them, if it's a problem), please try the following with the driver in Ubuntu -
    Code:
    sudo modprobe -rv rtl8723ae
    sudo modprobe -v rtl8723ae swenc=1 ips=0 fwlps=0
    See if this helps improving the connectivity. If not ONLY THEN try the proprietary driver with some patching as suggested in this post , and let us know the result.

    Got the same chipset and the same problem. This didn't help in my case.

    I'd suggest to post your case in a different thread with a detailed description of your problem, solutions you have tried so far, and the report generated by wireless_script (follow the link in my signature below).

    Feel free to post a link to it here so we can follow.
