View Full Version : [ubuntu] D-Link 642 and my Lenovo T60 -- doesn't work

I apologize if this has been answered before - -but I couldn't find a clear answer.

My Lenovo T60 has 802.11a/b/g built in (and I can connect wirelessly just fine). However, I'd like to benefit from my D-Link 625's "N" support. I have plugged in my D-Link DWA-642 Rangebooster N Notebook Adapter -- but it doesn't seem to be recognized by Ubuntu (8.04 LTS). Neither the Link nor Activity LEDs blink.

I am not sure if the card is being recognized at all... (It's a PCMCIA card.)

Any help would be greatly appreciated.

Thanks!

It appears that my card is being "noticed". I executed "lspci", and this is what I see:

16:00.0 Ethernet controller: Atheros Communications Inc. AR5416 802.11abgn Wireless PCI Adapter (rev 01)

If the card is being recognized and it's an Atheros card, you need to enable two drivers in restricted drivers manager for it to work.

Thanks for responding, AVT.

Both drivers are already enabled (assuming you mean the "Atheros HAL" driver and the "Atheros 802.11 wireless LAN cards" driver). The T60's built-in wireless chipset is also Atheros -- and I have been using the internal chipset for some time.

Maybe the issue is that there is no eth1 or ath1 interface associated with the PCMCIA wireless card?

Post the output of:

ifconfig

And the contents of:

/etc/network/interfaces

Also, are you using network manager?

I am using Network Manager. Here's the other info you requested...

In network-manager, go to manual configuration. Do you see the wireless card? If so, then everything should already be working.

What happens when you try to connect using network-manager?

Hmmm. I've got roaming enabled, so everything is grayed out in the Manual Configuration mode. I do not see any way to me to determine if my card is there or not...

Is there something in /proc I can look at?

Wait a minute, I just realized your laptop has onboard wifi.

Can you try disabling it in BIOS? If so, does iwconfig show any wireless cards?

Also, the thing that concerns me most is that there is no LED activity on the card -- ACT and LINK are solid off.

I missed your most recent post.

I can try to disable it -- but, not right now :-)

I'll give it a try and see what happens. I'll post back later.

Thanks for your help...

Well, when I disable the internal wireless device (via the BIOS), the PCMCIA wireless card still doesn't do anything (and I am left with no wireless support at all).

I have Device Manager installed. For the internal wireless card (after I re-enable it in the BIOS), Device Manager shows the following "tree"

PCI Bridge
Ethernet Controller
WLAN Interface
Networking Wireless Control Interface

For the PCMCIA wireless card, this is what I see:

PCI Bridge
Ethernet Controller

Any ideas?

Thanks...
