D-Link DWA-123 USB Wireless adapter strange issues

English Network/Internet
#1

Hi Guys,

I am running openSuSe 13.1 and I am having some strange issues with my D-Link DWA-123 USB Wireless adapter, which actually uses the Ralink rt2860 driver. The weird thing is that the device actually works with ifup, but NetworkManager shows it as hardware disabled. The stick has no button to actually disable it. I tried with Kernel 3.12.1 and am still running it, but the same behavior was with kernel 3.11. It worked pretty good under openSuSe 12.2 and NM discovered and used it correctly.

I did a fresh install from a DVD and my laptop is an old ThinkPad z60m. To avoid confusion the integrated Intel wireless got broken and is always hardware disabled. Please let me know if you need additional information or if anyone has a clue. I also tried downgrading the NetworkManager to the one from Gnome 3.6, but it appeared incompatible with SystemD, upgrading to the one from Factory, i.e. Gnome 3.10.2 did not make things any better. Basically I can live without NM, but I am not certain if ifup supports VPNs and how exactly am I supposed to create and connect to a VPN network.

Thanks a lot for your help.

Here are the outputs from rfkill and nm-tool.

As long as ANY wireless device is reporting a hard block, NO wireless device
can function. That is how rfkill should and does behave. I thought ifup worked
the same as NM in that case. If not, that is a bug in ifup.

If you have a dead device, you should never load the driver for it. You need to
blacklist the driver for that Intel device. Then rfkill will show no blocks and
NM will work.

Man, THANK YOU so much. I would have never guessed that the broken Intel card might be the culprit. You saved me so much hassle.

Thank you sooo much.

If it is possible for the forum admins to close this thread as solved. Thank you. :slight_smile:
