F10 WPA-PSK TKIP Help?

3do · #1 14th February 2009, 07:06 PM

Wow, thats alot of acronyms, but in short, I cannot connect to my wireless network in Fedora 10 or Kubuntu 810 due to the fact that I can not switch from the current key setting, which I assume is AES, to what I need, which is TKIP. I could select which one I wanted to use in (K)ubuntu 8.04, but I wanted a more advanced Distro, so I have come to Fedora.

If you right-click the NetworkManager icon, you should be able to configure the connection settings... I forget exactly what's there, I've had too much trouble with WPA and Linux so I've been using WEP for a while now. Not great since you can crack it in under a minute but I figure the point isn't keeping hackers out, but keeping them away. If there's a wifi connection down the street that's unsecured, I doubt they'll be spending the time to crack mine.

When I go to 'Edit Connections' I put in that it's WPA/WPA2 Personal, and the passphrase, but ther is no selection for AES or TKIP, so when I try to connect it prompts me for a password, I enter, it prompts again, and so on. Each time it prompts me, it has the same random password entered: 38c799b85.....and it continues for an unusually long way. I assume it is hex, but I am not sure. I just need it to know I use TKIP.

Ah, yup that's exactly the problem I had! I never solved that one, I gave up after days of toying with the settings just switched to WEP.

Hehe. I'll do that. Thanks for helping.

By the way, what card and access point/router is this? What's really weird is that I only had this problem with a specific card and access point, and using another card (or router) with WPA TKIP would work fine... It was really bizarre.

Well Firewing tell us the one you were using. I'm in the market for a new AP and I want to avoid one that is going to be finicky.

I don't have the exact model (wasn't at my place) but it was one of the older Netgear wireless a/b/g routers and I also had the problem with D-Link DI-624. The card was a Broadcom Corporation BCM4328 802.11a/b/g/n.

Hello 3do,

Well, at least that part of this is normal. What you are seeing there is the hexadecimal key that is created from the ASCII passphrase and SSID that you entered into NetworkManager when you first were prompted for it. It's derived from a complex hash calculation performed on the passphrase and SSID. Anyway, I see that in NetworkManager, too.

I don't think you need to worry about that. I guess NetworkManager doesn't ask for that because it can figure it out. BTW, I use WPA TKIP, too. No problems with NetworkManager.

I can't promise anything for that, but I can say that I went around and around with that when I first tried to use NetworkManager. I have no problem with it any more though. Here are just some ideas to try or at least think about...

Open your router's setup utility and confirm the encryption method and passphrase. I know you think you know it already. But I would just check. Two separate times I sat there pecking in the wrong passphrase over and over. And it's happened to other people here before, too.
Connect to the Internet by wire (if possible) and update at least the kernel and NetworkManager. If you have the time and bandwidth, I would update the entire system.
Right-click on the NetworkManager panel tray icon, "Edit connections...", Wireless tab, delete any duplicate connections in there. Restart NetworkManager (service NetworkManager restart).
Do that again, but delete all of the connections in the Wireless tab. Restart NetworkManager. Look for your network in the the list of available networks. Try to connect. Enter the SSID and passphrase carefully.
If you have created a wireless connection the Network Configuration utility (system-config-network), go in there and delete it. You can also delete its config files (/etc/sysconfig/network-scripts/ifcfg-wlan0, /etc/sysconfig/networking/devices/ifcfg-wlan0). If you're nervous about that, then just move them somewhere. I don't have those any more. The same goes for /etc/wpa_supplicant/wpa_supplicant.conf and /etc/sysconfig/wpa_supplicant. None of that stuff is needed anymore if you use NetworkManager. And I have at least two examples of those things impeding NetworkManager...

I hope you get this working. The thing works great for me. No promises though. Maybe it's like Firewing1 said and related to specific hardware. Who knows.
