Getting started with wireless connection

[beacon]

I successfully set up a wireless connection on one computer. I recently got a second computer of the same type from the same source. Both have Linux Mint 17 with the cinnamon desktop. On the first, when I go to network settings I am given a choice between wired and wireless. On the second there is only wired, and even though I have tried to use 'add' to create a wireless connection and used the same settings as on the first, nothing changes, and the page still shows only 'wired' and no option for 'wireless'. I wonder if I have simply overlooked something quite simple and would be grateful for help.

Lets see if LM can find a wifi device

Code: Select all

lspci -nnk | grep -iA2 net

Should find any PCI(e) network device

Thank you for your help.

I have typed in the code you suggested and got the following.

For the computer that is already connected wirelessly:

02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 06)
Subsystem: Gigabyte Technology Co., Ltd Motherboard [1458:e000]
Kernel driver in use: r8169

For the computer I am attempting to connect:

03:00.0 Ethernet controller [0200]: Qualcomm Atheros QCA8171 Gigabit Ethernet [1969:10a1] (rev 10)
Subsystem: ASRock Incorporation Device [1849:10a1]
Kernel driver in use: alx

I confess I don't understand, but even I can see these are different. I'd be grateful if you can give further advice based on this information.

Thanks again.

You must be using USB wifi sticks

Code: Select all

lsusb

Code: Select all

rfkill list

That was quick. Thanks.

For the first code on the connected computer I get the following:

the rf kill list does nothing that I can see.

It seems that there is no wifi device on the second computer

Thank you JeremyB. It appears that there is nothing I can do, and I'll have to get in touch with the chaps who put it together.
