    Wireless Intel Advanced-N 6502 does not find most of the SSID

    Hi,

    I just bought a Lenovo X220T (type: 4298-RD9), but the wireless card does not find most of the SSID. I said most of them, because it does find my android phone when I active the tethering mode. Another strange aspect is that I have the Lenovo T420 with the same wireless card and it works well with the same AP... I had a look at the forums this afternoon and found many issues with this card. I also tried the compat-wireless solution, to o avail. If someone could help me, it would be very appreciated.

    Some output (I also have a usb wireless card inserted (and working fine).

    Update: To complement the issue, please find hereunder the result of iwlist wlan1 scan from the Lenovo T420 (I moved down the ESSID # 2 to 9 in order to have first my home wifi, then my android phone, the only one found by the x220t computer):

    Re: Wireless Intel Advanced-N 6502 does not find most of the SSID

    Update: I thought I had detected a difference in the output of dmesg | grep iwl between my X220T and my T420 laptops ("iwlwifi 0000:03:00.0: Not sending command - RF KILL"), but after having uninstalled the compat-wireless, the 2 computer gives the same result... So I delete this message.

    This is the new output of this command on the X220T (without compat-wireless):

    Re: Wireless Intel Advanced-N 6502 does not find most of the SSID

    Hi,

    Eventually, the problem had nothing to do with Ubuntu. I restored Windows 7 and figures out it had the same issue. I then decided to open the laptop and realized that the antena cables were not plugged on the wireless card... Very strange for a new Lenovo laptop!

    Now everything is working fine!

    Best regards and thanks for your support!
