wireless not working


hello,

I had a wireless connection and everything was working properly until I tried to insert an ethernet cable to have wired connection. I think it's what caused this, but I'm not 100% sure, it could be something else.

In any case, I now have the following problems:

- I don't have access to internet anymore: it keeps trying to log into the wireless network, but nothing happens. All pings to google's ip address return a icmp error.
- I get an error when ubuntu boots : open /dev/null failed: no such file or directory
- If I don't remove the lines I had added in /etc/network/interfaces (which are:
auto wlan0
iface wlan0 inet static
address 192.168.0.10
netmask 255.255.255.0
gateway 192.168.0.254
), I don't have the wireless icon in the notification area
- When these lines are present and I don't have the wireless icon, it reappears after I type sudo killall NetworkManager & sudo /etc/init.d/networking/restart & sudo NetworkManager, but when it reappears, it says that the wireless device is not handled.

The wireless works otherwise (for all the other computers, which are not linux).

Please help me, I'm lost.

Thanks

First, look at the Gnome menu. There may be a category named System. Look in that category for any thing relating to system settings, networking, etc. Try to manually discover the ethernet connection and get it set up.

Second, try the Ubuntu wiki or Ubuntu documentation, looking for networking setup.

I already did the settings manually, the network is actually hidden (essid not displayed). I think I know how to set it up, I did it various times already, but apparently there is some bug in Linux (maybe the error is related to the one I get at boot time: open /dev/null failed: no such file or directory) that makes it not work. The wireless network I'm trying to connect to is working and is accessed by other computers in the same area, and the computer (ubuntu) I'm trying to configure to access this network can successfully join other wireless networks in the vicinity. But when I put together the network and the ubuntu computer, that work well independently, the computer can't reach the network. It just keeps trying and nothing happens.
It's not due to a password problem, I double checked that it's the same as the one in other computers that access the problematic network, and it's not due to a configuration problem, otherwise it wouldn't connect to any other wireless network.

I'd also like to re-mention that it worked well until I connected a wired connection to the laptop.

I'm really lost, I don't understand what's wrong.
Any help would be greatly appreciated.
Thanks.

Just add "wl" to text file /etc/modules,I think it will solve problem ,Best of luck.Remember you should have root permission and for that use sudo,after that save it and restart the machine.
