Maya not detecting wireless network on new laptop

[PiMinto]

At work I've put Mint 13 on a new Toshiba laptop (internet access restrictions make the latest version unfeasible). It doesn't pick up any wireless network although there is definitely one. The machine has Win 7 on as well, and wireless works fine in there. How should I begin troubleshooting?
If I look at System Information, under PCI it shows the ethernet controller as being a Realtek RTL8101E/RTL8102E, and although I don't understand any of the fields there it looks as if it's working.

Hello PiMinto,

could you go to a terminal and type the following commands one at a time and post the output here?

Code: Select all

lspci
rfkill list all

then we may beable to help further. I suspect that you have wireless card that uses proprietary drivers and they will need to be installed.

The output from lspci is:

your wireless card is the Realtek 8723 which has been know to be problematic on linux.
However here is a page that may be of help:

Sorry but there is not a good track record with your card.

[PiMinto]

Thanks, I'll have a look at that.

Hello eduardo108,

I'm unable to help you at the moment, but you should really post this equerry as a new thread. as it's not likely to be seen by those that may be able to help on this one.

Here's an easy way to get RTL8723AE ("Realtek Semiconductor Co., Ltd. Device 8723") working.

Please download this driver package: https://www.kernel.org/pub/linux/kernel ... 3-2.tar.xz
After extracting the XZ file, go to the folder where you extracted it, right-click > Open in Terminal, then run these commands to install it:

Code: Select all

./scripts/driver-select rtlwifi
make
sudo make install
