I cannot see wireless networks now that I have converted my Windows machine to Ubuntu.
I recently did a complete install of Ubuntu over my (formerly) Windows machine. At first, the driver that controlled my wireless card (internal) was not part of the package, but Ubuntu quickly found a list of updates that on the internet (via ethernet line - no problems) that fixed at least part of that problem. Now, my wireless card will turn on, but I still don't seem to be able to see any wireless networks, even though a second (Windows) machine sees several wireless networks. I have tried:
1. Connecting using Network Manager - there is no list of wireless networks to choose from
2. Manually connecting - my network name does not show up in the Network name (ESSID) drop down box (even though my Router does broadcast its name), so I enter the name manually. My router does not require a password, so I leave the Network password box blank. My router assigns IP addresses, so I set Configuration to DHCP and press OK - still no wireless network available to select in Network Manager.
2b. Manually connecting using a password - same as above, but I enter the administrative passord of my router (not necessary for my Windows machines to connect) NOTE:in both cases the Password type is set to WPA Personal. I don't know what this means, but it seem to be the default setting. - Still no wireles network available to select in Network manager
2c. Manually connecting using static IP and no password - SAME RESULT
2d. Manually connecting using static IP and password - SAME RESULT
3. Verified that hardware is recognized - I cannot find Device Manager on my system - NO LISTING FOR HARDWARE INFORMATION under System > Preferences. By going through System > Administration > Hardware Testing, my machine reported finding my Wireless card (Broadcom BCM4306 802.11b/g Wireless).
4. Verified that driver is present in System > Administration > Hardware Drivers (Broadcom B43 wireless driver - Enabled and In Use)
4b. Verified that diver is present using >sudo lshw -C network. Reports as follows (after my ethernet connection and network controller):
*-network
description: Wireless interface
physical id: 2
logical name: wlan0
serial: 00:0b:7d:17:79:60
capabilities: ethernet physical wireless
configura
NOTE: This ip address here is the one I attempted to use in steps 2c-d
5. Checked for a connection to the router using >iwconfig. Reports as follows:
lo no wireless extensions.
eth0 no wireless extensions.
wmaster0 no wireless extensions.
wlan0 IEEE 802.11g ESSID:""
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
So.. looks like NO CONNECTION TO ROUTER.
6. Attempted to Connect to Other Wireless Network in the Network manager. Now, wireless network with the Network Name I entered will show up in Network manager with 0 signal strength. After doing this, the Network manager icon disappears from the Taskbar, and a reboot is required to restore it and my wired ethernet connection.
7. tried >sudo apt-get install wpasupplicant. Result: wpasupplicant is already the newest version.
SO... now what? Is my wireless card not supported? I assume it fis airly common - it is in an off-the-shelf Dell Inspiron 6000 laptop.
