[SOLVED]No network interfaces on Dell Inspiron 14R N4010

Hullo people.!

I am a past Arch user who is returning back to his favourite distro after a long hiatus. I am trying to get the internet to work on the LiveCD for netinstall but have been unsuccessful so far. My setup consists of a cable modem that connects to my Dlink wireless router. The problem is, the LiveCD does not recognise either the wired or the wireless network inteface on my laptop.

ff:02.3 Host bridge: Intel Corporation Core Processor Reserved (rev 05)

I have tried modprobing atl1c (for wired) and both bcm43xx and b43 (for wireless), but it still is a no-go. With b43 though the output of lsmod | grep b43 yields:

b43                   172775  0 
ssb                    44979  1 b43
mmc_core               52043  2 b43,ssb
pcmcia                 29658  2 b43,ssb
mac80211              171331  1 b43
cfg80211              126817  2 b43,mac80211
led_class               2609  1 b43

So I am guessing this must be the correct module to load for my wireless adapter. Howver, ifconfig -a still shows only loopback interface.
Any help on the matter.?

P.S.:
The validation question during registration is more trouble than its worth. Since I only have Win7 installed on my lappy at the moment, I had to copy the command and save it in a text file, rename it to *.sh, then boot into Arch LiveCD, mount the windows partition, run chmod +x filename.sh followed by ./filename.sh > output.txt, reboot into Windows open the output.txt file and copy over the contents on the registration page. It took me lesser time to type out this post......

You need firmware for b43 - see the Wireless Setup page in the wiki.

Also check dmesg output when b43 is loaded.

Re: [SOLVED]No network interfaces on Dell Inspiron 14R N4010

A bit more research into my problem reveals this (not that I am anywhere close to solving it yet...)

Wired
Support for my wired adapter has been added in kernel 2.6.34. But as luck is never on my side, the LiveCD has 2.6.33. Possible solution is to update the kernel in LiveCD image to 2.6.34 and then boot from it. Since, I am a kernel newbie, but have a sneaking suspicion that it can be done, can anyone point me in the right direction to do this.?

Wireless
Refering the wiki page tells me that my card is supported by the broadcom-wl package available in AUR. But no net access = no AUR.!

Really looking forward to get this issue sorted out and enjoy Arch on my lappy.! I'm pretty sure I can handle any other problems once I have net working on my setup..

The archboot alternative installer has a more recent kernel - details in the wiki.

Or you could boot any recent live cd/usb with kernel >=2.6.34 and use the "Install from Existing Linux" method, also in the wiki.

Re: [SOLVED]No network interfaces on Dell Inspiron 14R N4010

Using Archboot with kernel 2.6.35 did the trick for wired.
Now I need to test the broadcom-wl package frm AUR for my wireless...Thanks for the help.!

The broacom-wl drivers work for wireless rather well.Only thing to note: the wpa_supplicant package in Arch does not include drivers for broadcom and wext doesn't work.So you might want to enable WEP or just use Network Manager, like  I now do.

Re: [SOLVED]No network interfaces on Dell Inspiron 14R N4010

FYI wpa_supplicant will never support broadcom-wl, as it's a non-kernel driver provided by Broadcom. wpa_supplicant does support the kernel's b43 driver via wext, but that may not work with your card.

I suggest you try the new brcm80211 driver - it says there that your card is supported, and it is the future of linux broadcom support.

Hi bro!

I am trying to set up the wireless card of my notebook inspiron r14. I installed the broacom-wl drivers too. This is what I get after a iwconfig

#iwconfig
eth0    IEEE 802.11  Nickname:""
          Access Point: Not-Associated   
          Link Quality:5  Signal level:0  Noise level:0
          Rx invalid nwid:0  invalid crypt:0  invalid misc:0

However I can't to scan available networks

#iwlist eth0 scan
eth0   Failed to read scan data  :  invalid argument

thoughts? did you face the same problem?

Thanks

Try the scan as root user.
