Need Help...please

[lwpack]

Hello. I've been trying to get my WG111v2 wireless USB adapter (chipset rtl8187) to work for a while now, but no luck. I have a Vista/Ubuntu 6.10 dual boot. On the Vista side, it works no problem, but I can't get it working in Ubuntu. According to the Ubuntu website, this adapter should work "out of box" with a native driver, but it doesn't. I've also followed several tutorials using ndiswrapper, but that hasn't worked either. I don't know how to proceed. Below are the results of several commands that might help. I'd really really really appreciate any help. Thanks!

lwpack@lwpack-pc:~$ iwlist scan

Anyone have any ideas? I can post the results of any needed commands, just let me know.

Put in your ESSID and key (If needed) and ping your wireless router. Tell me what happens.

According to iwconfig, your wireless adapter is working, what happens after this

ifconfig wlan0 up
iwlist wlan0 scan

Oxygen, Juan Pablo,
Thanks for the replies. How do I ping my router? Just type ping then the IP address? I did that and it said, "Network is unreachable."

Here are the results of the commands suggested by Juan Pablo:

lwpack@lwpack-pc:~$ sudo ifconfig wlan0 up
lwpack@lwpack-pc:~$ iwlist wlan0 scan
wlan0 No scan results

ifconfig wlan0 up
iwlist wlan0 scan

So what do you make of it? Ubuntu seems to recognize my adapter, but can't detect any networks. It doesn't make much sense to me, the network is unsecured, and it's definitely broadcasting as I can connect to it in Vista (I have a dual boot) with the same adapter. Again, here are the results of the commands you suggested:

lwpack@lwpack-pc:~$ sudo ifconfig wlan0 up
lwpack@lwpack-pc:~$ iwlist wlan0 scan
wlan0 No scan results
