No wireless or internet with hardy heron

**dr-spangle** · May 14th, 2008

A couple weeks ago I upgraded my dell inspiron 6400 laptop (bought with vista, formatted and gutsy gibbon installed) to Hardy Heron, I had tried the beta out on live disc a few times before and it seemed fine but when i upgraded to hardy heron i immediately noticed that the internet speed seemed at least 10 times slower.
I heard about ndiswrapper from a friend who uses ubuntu and thought it might fix it so i installed it and got some driers from dell and tried to use them... when i used them the internet slowed to a stop so i restarted and it wouldn't boot up, just flashing the caps lock and scroll lock LEDs once a second, as i had everything backed up to an external hard drive I formatted my hard drive and installed ubuntu again, but it won't connect to the internet now, with wireless or with a cable attached, it just asks for the wep key, loads and then asks again a couple minutes later...

my wireless card is an intel PRO/Wireless 3945abg Network connection and my ethernet controller is a Broadcom BCM4401-BO 100Base-TX.

I read somewhere to put "dmesg | grep iw" into terminal... here's the output:

Code:

Please and thank you.

You might try installing linux-backports-modules-hardy-generic. There are some things out there for your wireless card.

I tried internet with the cable again and it started working, but wireless doesn't work yet...

@balagosa: Dell, Inspiron 6400

@Ayuthia: ok... I've installed that via apt-get... I'll restart now to see if it works.

**dr-spangle** · May 15th, 2008

It didn't work, it just made the computer really laggy... so I uninstalled it again...

**dr-spangle** · May 16th, 2008

I tried it again today, same effect in that it didn't effect the wireless but made my keyboard and mouse jumpy...

sorry...

our only LAN cable is 150cm long and i have to unplug the desktop to get it...

if no one knows how to fix it i'll just go back to Ubuntu 7.10

Type "ifconfig", and "route -n". This will reveal why your computer is buggy when you plug in you UTP (unshielded twisted-pair).

If you want to use the UTP port instead of WiFi, try issuing "ifconfig wlan0 down" so your computer will know not to try to route packets through the air.

If that doesn't work, try "/etc/init.d/networking restart", then "ifconfig wlan0 down" again.

These steps will NOT fix your WiFi, but should enable you to work with a cable.

IHTH (I hope this helps).
