caannot connet to wireless network in ubuntu 10.04


I have ubuntu 10.04 netbook edition running on dell mini 10 and i cannot connect to my wireless network. I entered in everything on the editing wireless network section of ubuntu. However when I try to enter in the mac address as soon as I start typing the apply button becomes unactive. I have entered it before and I did connect to my wireless net with my netbook. However I tried top connect this morning and I wouldn't let me! I did not connect automatically to my wireless net work as it had before. I am typing this message on my desktop using the same internet connection so, I know that the net is active. Any help would be greatly appreciated!

please post the output to:
Code:
lspci # will tell us the pci devices you have in your system.
lsusb # will tell us the usb devices you have in your system.
ifconfig # will tell us what network interface cards that are turned on you have on your system.
ifconfig -a # will list all network interface cards you have on your 
iwconfig # will tell us which of your network interface cards has wireless capability 
lsmod # will list the modules that are loaded on your system.
once we know the above information; these commands usually get people conected to their wireless routers:
Code:
sudo iwlist <network-card> scan # this will use the <network-card> interface (that from the iwconfig command above) and scan for wireless routers that are accessible.
sudo iwconfig <network-card> essid <your-router-name> # assuming no security (the access point names will be provided by the previous iwlist command).
sudo dhclient # will attempt to get ip-address, subnet mask, dns server information automatically from your router assuming dhcp is turned on on your router.

when I try to enter in the mac address... reply to yooy

Yes It always asks me for my mac address, ssid, bssid, mode(adhoc or, infrastructure) & mtu which is set to automatic. I entered all this before but now I cannot again! I did it once so, I know that i must have done something right.

what happens when you do sudo iwlist eth1 scan

whats weird is i dont seee any broadcom driver in your lsmod but i dont think that matters since iwconfig is listing your wireless card.

what happens when I do a scan for: sudo iwlist eth1: It tells me unknown command 'eth1' (check 'iwlist --help') What do I need to type? B/C I obviously mistyped something. Thanks for all your help!

If wireless suddenly stops working on your laptop / netbook, the first thing to check is: Is the wirelesss switch turned on?

However when I type in: "sudo iwlist accesspoints" it gives me this:
lo Interface doesn't have a list of peers/access-points
eth0 Interface doesn't have a list of peers/access-points
eth1 Interface doesn't have a list of peers/access-points
