wicd is normally what I recommend to use. =X That or the Gnome Wifi manager that Ubuntu uses... For some reason I've had the Gnome Wifi crap detect and connect better than anything yet. It makes me angry too, cause I spent 30min trying this laptop a while back. I tried the Gnome Wifi gui/setup and it connected instantly. I was happy and angry lol

First things first. How do you know your wifi can see your modem? Can you ping it and get a return time?

If that is the case there seems to be nothing wrong on your wifi end but rather some setting in the modem. So that begs the question are you sure you have a wireless modem and that your ISP allows such connections directly through wireless? That is pretty uncommon. Most ISPs like to discourage this to minimize bandwidth usage and charge for Internet Sharing (Knowledge = Power = Wealth)

If this is the case, as is most common, you just need a router so that you get a wired connection from device to modem and let the router handle sharing.

Note: if said connection works in Windows that could be a clue that some application added layer having to do with TCP/IP and sharing is being used. Personally, even though I have considerable skill setting up software firewalls, I would never connect a PC and especially a Windows PC, directly through the modem. I require the added layer of a hardware firewall upon which I can set the rules. ISPs frown on, severely frown on, any user settings in their modems.

Bottom Line - whatever else (and you could post the contents of "etc/resolv.conf") you need to discover if this is the case with your modem and ISP before anything else.

Hope this helps.

I have a ip and I have connected to my ssid
it takes my WEP key and connects but thats about it
If I go to the package manager or Firefox I get no Internet connection
the connection dose work in windows and Ubuntu

here is etc/resolv.conf

OK then apparently your modem has some router function built-in.. at the very least a DHCP daemon since you have an IP and did not mention setting it manually. Because you didn't list the modem brand/model I don't fully understand yet just how much router function your modem supports.

Wait! I think I see a problem.

It is not good (and maybe impossible for function) to have your Broadcast address = default Gateway = DNS

192.168.1.254 is a common Bcast but I have never seem it used as Gateway. It should be something like 192.168.1.0 on both your wifi nic and your modem/router. However it may be possible to get it to work simply by editing "/etc/resolv.conf" and adding these lines

Code:
  
nameserver 8.8.8.8
search  8.8.8.8
where 8.8.8.8 is Google's DNS service

If that doesn't work I'd either change Default Gateway as above or check with either of the operating systems that work to compare Gateway addy.

lol it's the WEP encryption I'm betting. There's some problematic settings with WEP and linux that tends to give you an IP but not internet access. I'm betting if you remove security and have an open network it'll work fine, going back to the WEP problem. I can't tell you the answer, because I don't remember it and I don't deal with wifi period (speeds are slower, always). I'm just sayin try it without security, if it connects you'll know where to start looking.

Broadcast should be 192.168.1.255. Your gateway is fine assuming it matches the IP of your router's interface.

The nameserver is not necessarily wrong depending on your network but 8.8.8.8 is a known working server so is a good idea to try that as above.

That Bcast addy is by no means cast in stone as a rule. The only rule for Broacast is that it be higher than any addy you want it to be able to broadcast to all inclusively. You could set BCast as 192.168.1.2 if you wanted but it would then only broadcast to two addresses, 0 and 1.

The gateway address can also be anything you want within the limits of how you've setup the network but SOP is that it should be the lowest, the exact opposite of Bcast.

I didn't mean to say that setting your router's Gateway as your DNS was wrong or wouldn't work, as it commonly does. The idea was to jump right to an external search rather than an internal one.

We still don't know exactly what OP is calling a modem.

can you ping your gateway?, if you can't are you sure you don't have MAC filtering on?
