Problems connecting with D-Link DWL-122 USB wifi adapter


Specs
Wifi adapter: D-Link DWL-122 USB
Driver: prism2_usb (from wlan_ng package)
OS: Kubuntu Dapper


After fooling around with wlan_ng for an hour or so, I rebooted and launched wlassistant. I was pleasantly surprised to see that it was detecting my wireless network, signal strength was reported as full, and it displayed the correct channel, AP MAC address, etc. I confirmed that it was detecting it dynamically by turning the router on/off and making sure it recognized it.

I configured wlassistant to use the correct WEP mode and key when connecting to my network, but whenever I try I get a "Connection failed" error. I've tried temporarily disabling WEP and MAC address access control to see if those were causing problems, but it didn't help.

So, it appears that the wifi adapter and drivers are working, but I still cannot connect. What should I do?

Go into your terminal and type iwconfig... and maybe even iwspy. Copy+paste them onto here so we can hit the ground running.

Well, I switched from the DWL-122 to a PCMCIA Netgear MA401, which didn't require any wlan_ng fiddling. I've noticed the same connection behavior with this card as the DWL-122. Using the new card, here are the outputs you suggested:

iwconfig
eth2 IEEE 802.11b ESSID:"SandersB1" Nickname:"Prism I"
Mode:Managed Frequency:2.462 GHz Access Point: 00:09:5BA:676
Bit Rate:11 Mb/s Sensitivity:1/3
Retry min limit:8 RTS thrff Fragment thrff
Power Managementff
Link Quality:92 Signal level:0 Noise level:114
Rx invalid nwid:0 Rx invalid crypt:1 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

iwspy:
eth2 No statistics to collect

Hmmm, try doing this open up your internet browser and type: 192.168.2.1 ........... This should connect to your router as you may know. This will probably help a lot because your problem may be with your router and not with your wireless card. Also by googling I came across a fix for another guys problem he was wireless on eth2 and he had switched from eth1 somehow.....

Anyway to fix it in his terminal he typed:

dhcpcd -d eth2


........................ I'm gonna open up my Ubuntu real quick I'll post this and respond again in a sec I have no idea what dhcpcd does... seee for myself here

Looks like for dhcpcd you have to install it as a package... Try using package manager or googling dhcpcd and you should find something in either.... Considering I'm using Ubuntu and your on Kubuntu I dont expect either too be too much different its prob not on your comp either....

Thanks for the replies,

Connecting to the router, just as with remote hosts, does not work.

I previously tried using dhcpd after reading this post: http://www.linuxquestions.org/questi...d.php?t=348868

It didn't return any errors, but also did not seem to work. I've just tried it again and confirmed.

I'd really like to test the laptop with another wireless connection, I'm not sure what else to do at this point.
