View Full Version : [ubuntu] Wireless card problems

August 18th, 2009, 06:16 PM
I am a refugee from MS Windows XP and the only thing stopping me making the break is the fact that my wifi on my laptop will not connect to my router, but the Ethernet works just fine.

Symptoms -

When I boot up it does not recognise the wireless router
If I create a wireless network in the network manager and then select it it after a while I am told that the network is disconnected

Things that I have tried or observed

Removing the fire wall makes no difference
I am not currently using security but I am using MAC
I have tried removing the MAC codes from the router but to no avail
It works just fine under Windows XP
When I return to Windows I have to force it to start looking for the Wireless Router
I have tried using the midwifi driver but no different
I have located the windows driver and down loaded it but have no idea at how to find the file with the extension .if

Hi rigg,

What a nice, organized post. Have you tried searching on google? I did a google search with the following as the query: "ASUS X50RL" ubuntu wireless

It came up with some useful links. See here for example: http://ubuntuforums.org/showthread.php?t=1074440

One of the links said that 8.04 worked fine. I would try a 8.04 live cd to see if that does the trick. Even if you don't want to use 8.04, just knowing that it works with it might help.

I wish I could give you better advice, but that's all I have. I really hope things work out! If you get a solution, be sure to post back.

Best of luck!

HI found the answer eventually I needed to chnage a setting as per another post on same topic viz
Re: No wifi in 8.10 on ASUS X50RL
I did the following:- gksudo gedit /etc/acpi/start.d/60-asus-wireless-led.sh

Then I switched the 1 and 0

The forums are really good if a bit daunting to search

great! I'm glad it worked out for you.

The thing that makes the search less daunting is when the poster with the problem posts back with what worked for him, like you just did!

yes, kudos for actually providing the solution that worked for you!

many times someone starts a thread and issues a trouble-call, only to receive many replies and various answers/solutions/tests/trials/etc and then there isn't any final disposition from the original poster

and a good, precise, descriptive title and specific specifications are always best!

again, thanks!
