I installled Ubuntu 10.4.1 on a brand new computer with a Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller on a Foxconn G41MXE motherboard. and I have been unable to connect to wireless network.

I have gone through the wireless trouble shooting guide to no avail. When i "check for device recognition" i get the following (note the is no CLAIMED UNCLAIMED ENABLED OR DISABLED)

I have read "how to post a wireless issue" ( as well as going dizzy searching forums and documents to find a solution myself) and the following info might assist you in helping me. Please tell me if i need provide any other information. Wireless Brand, Model and Wireless Chipset

Thankyou for your help

The Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller is your wired connection, not the wireless.

You might look at

lspci -nn

and see if anything looks like the wireless device, might say something like network or wireless or just post the output.


Also, if the problem is with your wired connection, you might look at the following

I guess i have exposed the level of my ignorance:)
lspci nn gave me the following. Which is my wireless adapter. Wired connection is no problem by the way

well I don't see it anywhere. Could it be a usb device? You might post the contents of

lsusb

also.

In your first post you said " Please tell me if i need provide any other information. Wireless Brand, Model and Wireless Chipset". Do you have any idea or the part number of your computer. You might also check the bios at powerup to make sure the wireless card is enabled.

Also you might look at

rfkill list

and see if it says yes to either "softblocked or hardblocked"

No it is not a usb device. The computer is a Novatech Isys PC1409

I went into BIOS but a bit unsure what to look for. I saw nothing which obviously related to wireless card . Under Onboard configuration I found Audio controller enabled , LAN controller enabled ,LAN boot ROM disabled.


Thanks very much for your help on this

I have googled, googlubuntu and gone to the website of Novatech and have come up empty. The Novatech forum has some wireless postings, but everyone had added card (all different too). Are you sure it has one? Sorry, just frustrated! Will still continue to look.

I will call Novatech Tech support tomorrow(closed today) and hopefully they will identify the wireless card. Could they really be selling a pc without wireless capabilities? I hope not.
Please advise me of any other action i might make.
Thanks again for your help

I just spoke to novatech who confirmed there is no wireless card. I'm am very sorry to have wasted your time. Thanks
