No wireless after install Debian Linux Wheezy


Title pretty much describes my problem.

I installed Debian Wheezy yesterday, and began with ethernet connection. This morning, I unplugged the ethernet and lost wifi. I couldn't figure out what to do, so I searched google. Some results indicated I needed to enable wlan0. However, there is no wlan0 interfact at iwconfig.

This is the result of iwconfig:
Code:
lo        no wireless extensions.

eth1      no wireless extensions.

eth0      no wireless extensions.
And the result of ifconfig

Code:
eth0      Link encap:Ethernet  HWaddr f0:92:1c:4e:a2:e6  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

Thanks for any help in advance!

You may need the non free firmware.

Enable the non-free repositories, update and install the relevant firmware. Sorry, I've not a system I can look it up on.

I enabled the non-free respiratories, but what firmware do I need?

I'm not at the console but I think it's something like firmware-linux-nonfree.

sudo iwconfig has the same problem.

What wireless card do you have? We need to know that to know which firmware you need.

I have installed Debian Wheezy on a few systems requiring proprietary drivers. Here's how I would approach it:

At the command line, execute lspci and look for anything to do with wireless. Here's what I get, and I've highlighted the relevant line:
Code:
$ lspci
00:00.0 Host bridge: Intel Corporation 82855PM Processor to I/O Controller (rev 03)
00:01.0 PCI bridge: Intel Corporation 82855PM Processor to AGP Controller (rev 03)
00:1d.0 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 01)
00:1d.1 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 01)
00:1d.2 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 01)
00:1d.7 USB controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01)
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 81)
00:1f.0 ISA bridge: Intel Corporation 82801DBM (ICH4-M) LPC Interface Bridge (rev 01)
00:1f.1 IDE interface: Intel Corporation 82801DBM (ICH4-M) IDE Controller (rev 01)
00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)
00:1f.6 Modem: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Modem Controller (rev 01)
01:00.0 VGA compatible controller: NVIDIA Corporation NV34M [GeForce FX Go5200 64M] (rev a1)
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5705M Gigabit Ethernet (rev 01)
02:01.0 CardBus bridge: Texas Instruments PCI7510 PC card Cardbus Controller (rev 01)
02:01.1 CardBus bridge: Texas Instruments PCI7510,7610 PC card Cardbus Controller (rev 01)
02:01.2 FireWire (IEEE 1394): Texas Instruments PCI7410,7510,7610 OHCI-Lynx Controller
02:01.3 System peripheral: Texas Instruments PCI7410,7510,7610 PCI Firmware Loading Function
02:03.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)
$
Then I would suggest you Google the name of the wireless controller together with the word "debian" and see where that leads. In my case, the first Google result is a winner. It is a page at wiki.debian.org that gives step-by-step directions for installing this wireless network driver. It is in the section titled "Installation on Established Systems." I did it by the command-line interface, but there may be ways to do it by Debian GUI tools.

For graphics drivers on other systems, my Google search led to the hardware vendor's web site where similar instructions were posted.

Good luck and let us know how it goes.

Google that (edit: I mean fragments of that) and I get:
https://packages.debian.org/wheezy/firmware-realtek
Package: firmware-realtek (0.36+wheezy.1) [non-free]
Binary firmware for Realtek wired and wireless network adapters
There is a download link near the bottom of the page.

The download page strongly recommends using a Debian package manager rather than installing it manually, so perhaps you should first try the software install/upgrade tools and search for "firmware-realtek" or perhaps more specifically "firmware-realtek_0.36+wheezy.1_all.deb"

I uninstalled linux nonfree firmware, installed realtek, restarted, installed linux nonfree firmware again, this time with no errors. However, I still cannot connect to wireless, and still no wlan0 in iwconfig.

I'm using realtek semiconductor wireless manager, device 8179.

This might have worked, but I've already fixed it.

For anyone with the same problem, the wifi-card realtek conductor 8179 is *not* supported in Debian Wheezy, as it runs on the 3.20 kernel.

By updating to Jessie, which uses 3.16, support is added -- updating to Jessie (testing) fixed my problem.

Thank you for everyone who tried to help me!
