Odd Wi-fi problem?

Post by ScottishGirl »

Hi guys I love Linux and Mint especially. :D

My problem is this, I can connect to the Internet with my Linksys 54G router but ONLY using the ethernet cable. Right clicking on the network manager shows that 'enable wireless' is greyed out. I have an USB adapter Edimax EW-7318usg which Mint or my computer completely fails to recognise. My BF runs Vista an he has no problems at all accessing the Internet without the ethernet cable. :oops:

Have you tried using ndiswrapper and the Windows driver for your wireless card? That will most certainly get things going. Cheers! :lol:

Hi ScottishGirl

Welcome to Linux Mint Forums. :)

I use that same exact USB adapter on my desktop system and it works excellent. It is known to work very well with Linux, which has the drivers for it already installed.

Looking at your output it appears that you have a PCI wifi card already installed too: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)

Also it appears that the system radio may be turned off as well: eth1 radio off ESSID:off/any and Bit Rate:0 kb/s Tx-Power=off.

From what I see "eth1" looks like its your onboard wifi card.

And "wlan0" is your adapter:

wlan0 IEEE 802.11bg ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=8 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:

Also notice wlan0 IEEE 802.11bg ESSID:"" does not have an ESSID inside of the "".

*Make sure that your radio switch (button) is turned on. This may be a physical switch located somewhere on the outside of your PC, or may have to be done in your BIOS. (not sure if this switch has control for all adapters though usually just onboard devices) Sometimes physical switches do not play well with Linux due to proprietary drivers that manufacturers keep to themselves, but there are a few workarounds, maybe!

*Unplug your Ethernet and the wifi USB adapter.

*Try the right click on network-manager again to see if you can see your network. If not hover the curser on options and see if "enable wireless" and "disable wireless" are both grayed out. Click "enable" if its not.

*Right click again on network-manager and click on "manual configuration". Enter your password when asked. If your wlan shows disabled there, click on configure, click on "dhcp" then ok. Click apply and ok any popup's that may appear.

*Now try the right click again on network-manager.




With the adapter you should be able to do the same steps as above.

**Sometimes if the adapter is not seen or keeps showing that it is disabled, you can simply unplug it for awhile then plug it back in and the system should detect it. If that doesnt work, you can also try unplugging the adapter, then restarting your system, then plugging the adapter back in ONCE the system has fully booted and stabilized.

Try this and repost if you need more help ok.

Hi all. :)

I still cannot enable the wireless radio button. My laptop is over three years old and I think the problem may lie with my computer simply not being able to recognise the adapter.
I downloaded a driver from Edimax but it has to be compiled and I don't know even how to begin doing that. As for ndiswrapper I have that installed but I don't know how to work that either. :oops:

Thanks for your suggestions I think that I will just have to get used to accessing the Internet through the Ethernet cable.

Ndiswrapper is not for this adapter. The Linux adapter should be installed in your system modules. If your bf plugged this adapter into his M$ box he would find that it will not work. He would have to get the windows driver off of the included cd that comes with the adapter. In Linux it is already in the system but there is also some Linux drivers on the cd as well. I will check and see what is listed there for ya.

Run

Code: Select all

cat /proc/modules
Also

Code: Select all

lspci -vv
On some computers this command does not always list the drivers next to the device output for some reason.

Please see this post also http://forums.linuxmint.com/viewtopic.php?f=53&t=24459
Here we were able to get his adapter working by blacklisting the driver for his PCI card.

Wifi can be crazy sometimes! :lol:
