Everything is fine except the wireless connectivity. So, please give guidance.. if I give the command sudo lshw in the terminal, this is the response I get: *-network DISABLED description: Wireless interface product: Dell Wireless 1390 WLAN Mini-PCI Card vendor: Broadcom Corporation physical id: 0 bus info: pci@06:00.0 logical name: eth1 version: 01 serial: 00:1a:73:4e:b6:10 width: 32 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=bcm43xx driverversion=2.6.20-16-generic latency=0 link=no multicast=yes wireless=IEEE 802.11b/g resources: iomemory:20000000-20003fff irq:17 But when I enter System-Administration-Network, Wireless connection is displayed. In the properties I have enabled roaming mode and have given the specific DNS no. I gave this configuration as another laptop with same version of Ubunto automatically took those setting and is working. Please help me sort out this problem. Earlier I was using windows XP. when I had got my XP installed it was displaying that the wireless is disabled. At that time, there was problem in the drivers for video controller. Once that was set right, the wireless also started working. Now, guide me what I have to do.. </blockquote><div> Google is your friend .At least mine ...
