Wireless problem ubuntu 10.04 (Solved)
Posted by Birodh on September 20, 2010
This works properly!
I got tired using Ubuntu9.04 because I could not use wireless in my Dell vostro 1320.
I upgraded that version to Ubuntu 10.1. But still the same problem. ….went through lots of forum got some idea and tried it but could not work.
Then I used following command to view my network card:
$ lshw -C network
then it showed following information about wireless network card along with other network card.
description: Wireless interface
product: BCM4312 802.11b/g
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:0e:00.0
logical name: eth1
so knew that the product vendor is Broadcom and product is BCM4312 802.11b/g
I noted that the series is 4321
then, I ran to broadcom drivers website for linux , following the link below.
there were lists of driver for different architecture of linux.
I checked my linux architecture using following commad
the output was:
Linux XXX-laptop 2.6.32-24-generic #41-Ubuntu SMP Thu Aug 19 01:38:40 UTC 2010 x86_64 GNU/Linux
see x86_64 in the above line. so it was 64 bit.
So, I downloaded the driver package for 64 bit. This package:
Unzip the package in a folder in desktop.
Then run following command in terminal. but make sure that your working directory is what you have unpackaged the downloaded driver.
When the build completes, it will produce a wl.ko file in the top level directory.
Ok then you can use following command to install the driver.
$ modprobe ieee80211_crypt_tkip
wl.ko is now operational.It may take several seconds for the Network
Manager to notice a new network driver has been installed and show the
surrounding wireless networks. But in my case it didn’t take even a second.
If above procedure didn’t work then try the following thins then repeat the stps above.
I used following command to check pre-installed drivers
$lsmod | grep “b43\|ssb\|wl”
It may show
b43 or ssb or wl , but in my case there was only wl.
I used following command to remove it.
$ rmmod wl
but you can try these too, if you have any of these installed.
“this is optional”
To blacklist these drivers and prevent them from loading in the future:
# echo “blacklist ssb” >> /etc/modprobe.d/blacklist.conf
# echo “blacklist b43” >> /etc/modprobe.d/blacklist.conf
Please let me know the result after you try.
