Wireless and WPA2

jerik · 2009-03-14 15:03:29

Hi, I'm struggeling a bit here. I'm trying to set up my wireless network. I have NetworkManager and the plasmoid installed. But I't doesn't get listed. My neighbours show up, so it's clearly that it works. I think mine is encrypted with WPA2. Could that be the reason?

Does anyone have suggestions to whats wrong?

Is your router broadcasting the essid?

jerik · 2009-03-14 15:16:12

well, it has always been easy to find it on mac and windoez computers... and also on a laptop running linux mint, and I haven't made changes to the router... so I think so.

You know, the best advice I can give you is to scrap networkmanager and just use Wicd. It's just so simple and reliable.

jerik · 2009-03-14 17:16:18

same with wicd
qustion: since I was to manage wireless with wicd, I should add !wlan0 to interfaces in rc.conf? Right?

I also notice the neighbours using WPA2

Yes, wicd should manage everything.
No references of any interface in the interfaces (or put a ! before) and don't put network on your daemons array (or put a ! before).
And yes, wicd has proved to be much better than networkmanager.

Is it just not showing up in NetworkManager?

Have you tried running

iwlist scan

as root (or sudo)?

If it shows up there, then maybe it's being excluded because of the WPA2 for some reason. It seems that you need the wpa_supplicant package in order to use WPA/WPA2 encryption; is it installed?

It doesn't appear in iwlist either.... and yes, wpa_supplicant is installed, and wooh... well, I even tried to upgrade the routers firmware... didn't help. It's weird becuase, I have two comoputers, and none of them shows the router, but all the others on the house does. And mine runs Arch and Kubuntu...

Can I sit to close to the router? Can that be a problem, now there is maby 2 meters between the PC and the router.

Can you post the iwlist output?

Strange. I'm at a loss. (I think iwlist would still show networks with non-broadcasting essids.)

Since your card seems to be working (though I'm no expert, maybe there is something wrong), I would blame the router, but if other computers are seeing it, unless they're wired - in which case I'd make sure the router is broadcasting at all, then you have a very weird problem .

Could it be something as simple as using an older wireless card with a newer router? e.g. 802.11n only

jerik · 2009-03-15 21:33:55

yes... it's a strange problem. my card is abg, the router is all those pluss n, but it's set to broadcast on all. could it be maby that someone has a stronger routersignal than me and somhow annihilating my signal? Is there f.eks. some setting to change frequenzy?

Edit: I just rebooted my kubuntu pc in to the old and dusty winXP and thatone actually found the router now..., so it seemes that it's a linux fault

You could change the channel # in the router configuration, but yeah it looks like Linux had a problem.

R00KIE · 2009-03-16 13:12:14

That may be the problem, if you set the router to use a channel that shouldn't be used in your country (or if the router selected it for some reason). Make sure you have crda and that you have configured it to your country (as well as the router).
Also you could try to check which channel winxp detects, try with netstumbler http://www.netstumbler.com/downloads/

jerik · 2009-03-16 13:28:43

WOW, it worked! The channel seemed to be the problem Weehaa! Thanks guys
