I just downloaded Ubuntu yesterday, so am kind of new at this, up until now I have been using Windows XP, but this seems much better. Anyways, my question is how can I install my D-Link DWA-542 On Ubuntu 7.10?

Hi RyanThePerson, Welcome to lq. Could you post the output from the following commands?

This should tell us what chip the card has and what modules are loaded.
Good luck ;-)

I have the same problem, I'm trying to make wireless work on my comp, I'm using ArchLinux so I'm guessing it will be a bit different, but this is what comes up for the wireless card:

03:00.0 Class 3a69: Atheros Communications, Inc. AR5416 802.11a/b/g/n Wireless PCI Adapter (rev 86) (prog-if 11)
Subsystem: D-Link System Inc Unknown device 3a69
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 11
Memory at dfbf0000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [40] #80 [0000]
Capabilities: [80] #00 [0000]

And I have the same card as him, D-Link DWA-542.

Hi SiegeMachine, Welcome to lq. You'll need the madwifi drivers for that atheros card. You can get them here. Be sure and follow the how to for first timers here.
Good luck. ;-)

Thanks for the help!

You're welcome, post back if you have any troubles.
Good luck. ;-)
