b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 6, Type 5, Revision 1) -> Wireless Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) not working on Dell Inspiron 1420 in Ubuntu 9.10

first find out which wifi adaptor you are using by typing 'lspci' at terminal (without quotes). If you have broadcom wifi adaptor then use the method as listed on this pagel
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

you can also install a program called "ndiswrapper" (google it or find in the ubuntu software center) and use your windows wireless driver in ubuntu.

If it does not solves your problem then reply me with the output of "lspci" (without quotes) at the terminal.

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread

Regards,

Mark

dear mr. mark,

"i've already try your suggestion and the result shows as above and its still dosn't solve my problem. for your information i am using Dell Inspiron 1420 notebook."
