View Full Version : Re: Satellite L755-13Q : WLAN N (802.11n) not visible, how to activate ?

I have a Satellite L755-13Q which is sold with a WLAN compatible with 802.11n wireless network but the n-WLAN are not detected by my computer.
The N-WLAN is detected on an other computer.

I have updates the Realtek RTL8188CE driver from the Toshiba download web site.
Driver option for network type is well set on 802.11b/g/n. Other B-WLAN are detected by my computer.

Have you ever seen this issue?
What could be done to activate N-WLAN detection?

Thanks and Best Regards

Are you sure that the WLan card is set to Draft N (802.11 N)?
In device manager -> WLan card -> Properties -> Advanced tab you can check if the Draft N is enabled and set.

If it’s set and the notebook would not recognize the wireless N network then you should update the WLan driver. I recommend choosing the one from Realtek page.
Of course you can also test the driver from here:

It could be also a compatibility issue between the card and the router.
Some WLan cards supports the 802.11 N standard only at 2.4Ghz band… so if you router supports 802.11 N only at 5Ghz then the notebooks Wlan card would no receive this network.

If the Realtek cannot see the router connection at all, then change the frequency to 2.4GHz on the router.

5GHz is generally a corporate frequency and not included in many Wifi cards.
