i am running kernel 2.6.32-5-amd64

is it possible the wireless switch is off even though it still scans with wicd?

not sure what's necessary information so please tell me what you need to know to help if i have not provided..

dabir · 08-31-2011, 08:32 PM

Though I don't want to admit it, the reason the wireless isn't working could perhaps be that I need a newer kernel for my wireless card.. or just that a newer kernel would fix the problem.

Would it be okay to patch my distro to the latest stable version? (3.0.4.)
and if possible, can someone please walk me through how I would do this?

Also, if upgrading is what it comes down to, do I have to uninstall my realtek wireless drivers that are for 2.6.34 and before before installing the drivers for 2.6.35 and later? (i don't know how to do this, either)

http://www.realtek.com.tw/downloads/...true#RTL8188CE

dabir · 08-31-2011, 11:06 PM

I feel as if I'm really close to establishing a wireless connection.. I've been at this for weeks.

PLEASE HELP

dabir · 08-31-2011, 11:21 PM

A google search lead me to this link:

http://www.mrmollman.com/blog/?p=43

And after doing that, that should be all there is to be able to connect.. what am I missing something??

hi2arun · 08-31-2011, 11:25 PM

Hi -

Did you try setting correct ESSID and wpa-supplicant conf?

What happens if you scanned with 'iwlist'? Do you see your SSID in broadcast?

yes, in wicd network manager the settings are correct and I use wext as the wpa-supplicant

scanning works, but it doesn't seem to get an internet connection after that (secured or unsecured)...
doesn't seem to establish any kind of connection

I installed wpa_gui and this is what it shows: (and scanning does not show anything, either)

But here is my WICD.. successful in scanning

does this mean anything??

I got the realtek drivers from that link above.. is there more drivers that I am missing?

Hardware checker says that chip in your wireless is working .

Wicd snapshot shows that Wicd is showing wireless Networks to connect to so your driver is loaded and working. All that is left is putting in your wep or wpa key to connect.

dabir · 09-01-2011, 04:39 PM

it still doesn't connect?

with the password on, it says "validating authentication..." for about a minute then says "failed: bad password"

with the password off, it says "obtaining ip address..." for about a minute, then says "failed: unable to get IP address"

I'm connected through the same wireless with another computer, so I know it's not that router itself.

Removed44 · 09-01-2011, 06:29 PM

I haven't been on these forums in so long, but I noticed you found one of my first blog posts (yay!). I'll see if I can help you.

Do you know which encryption method your wireless router is using? I don't know if you've tried this already, but try clicking on "Properties" for the wireless network, then make sure "Use Encryption" is checked. Then choose your wireless encryption method for your router from the drop-down, then enter your password and hit OK. Then try to connect again.

I chose WPA 1/2 (Passphrase) from the drop-down, entered my password, and my netbook connects just fine. I don't know if you've tried that method already, but it's worth a shot. Tell me how that goes.

That was your blog? Awesome

I've done that-- with correct settings. (and gone in to the router settings just to be sure)

But even when I remove the password, it STILL does not connect.. so I don't think it's a authentication error, it just says that.

No connection seems to establish in the first place.... :/

Removed44 · 09-02-2011, 05:03 PM

Hmm, this is very odd. Well your wireless chipset is obviously working because it can detect wireless networks, so we've made it that far. Can you possibly try connecting to a friend's router to see if it can connect that way?

Sometimes I notice it takes a while to connect to our home router, but I don't know if that's just our router, or my wireless chipset, or what. It could be a number of things.
