How Do I Enable the Wireless Adapter on My Acer Laptop?

I am new to Linux and just installed Mint 11, I ran "sudo lshw -C network" and got this: mike@mike-Aspire-3000 ~ $ sudo lshw -C network [sudo] password for mike: *-network:0 description: Ethernet interface product: SiS900 PCI Fast Ethernet vendor: Silicon Integrated Systems [SiS] physical id: 4 bus info: pci@0000:00:04.0 logical name: eth0 version: 91 serial: 00:c0:9f:ca:49:1e size: 100Mbit/s capacity: 100Mbit/s width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=sis900 driverversion=v1.08.10 Apr. 2 2006 duplex=full ip= latency=173 link=yes maxlatency=11 mingnt=52 multicast=yes port=MII speed=100Mbit/s resources: irq:19 ioport:1800(size=256) memory:e2005000-e2005fff memory:88000000-8801ffff *-network:1 description: Network controller product: BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller vendor: Broadcom Corporation physical id: b bus info: pci@0000:00:0b.0 version: 02 width: 32 bits clock: 33MHz capabilities: bus_master configuration: driver=b43-pci-bridge latency=64 resources: irq:17 memory:e2000000-e2001fff *-network DISABLED description: Wireless interface physical id: 1 logical name: wlan0 serial: 00:14:a4:35:bd:61 capabilities: ethernet physical wireless configuration: broadcast=yes driver=b43 driverversion=2.6.38-8-generic firmware=N/A link=no multicast=yes wireless=IEEE 802.11b

Hi Mike,...

Hi Mike,
Pity about the formatting- try putting the output into code brackets.

You've got wireless. If I read the output correctly, though, you seem to have two wireless network interfaces.
What does nm-tool say? And (at a guess) what's the output of sudo rfkill list
If you've got a block on the wireless, it could be a problem. There was a bit of noise a while back about some laptops where the wireless could be turned off in Windows in a way that meant that you couldn't turn it back on in Linux.

You don't need to do anything but click the "Network" icon in the panel and then "Enable Networking" and "Enable Wireless". You should then see a list of the wireless networks detected. If there is no "Enable Wireless" option when you click the "Network" icon, then look in the "Control Center" under "System" for "Wireless Netorking". There is no need to "type" stuff in a terminal with most Linux distros today.
