Hi trailer8713, Both connected just fine before what? What router/AP do you have? Have you possibly enabled mac filtering? Are you certain the security schemes all match, i.e., Mint machine, Windows machine, Fedora machine, router/Ap?
Good luck. ;-)

More information would be good. And to give you some stuff to tell us...

First, what do you get with iwconfig? Does it show your wifi card?

Second, iwlist wlan0 scan
(replace wlan0 with whatever your wifi card is called. could also be eth1 or eth2 or something. Your wired network is probably eth0 so not that one.)

Lastly, what do you mean by correct IP address? Do you mean the IP your computer with the intel card is given by the router or something else?

I use that card and have no problems at all with it. Works out of the box with no configuration needed in Ubuntu 7 and 8.

I was out of town for two weeks on business. Before I left everything worked fine I got home wifes windows laptop will not connect, sons desktop using a usb wireless adaptor does not connect I upgraded sons mint to KDE 4.0 after install worked fine did updates 198 total after reboot will not connect gives me an IP of 169.254.???, should be 192.168.???, I have a buffalo air station wireless G router we lost power for a couple hours while I was gone. didn't work after that I was told. My other 2 kids computers on usb adapters connect and work fine. My laptop will only connect for 5-10 minutes and disconnects some times it will reconnect some times it will not. That one is Fedora 9 686 with 2200 intel while I was out of town connected to hotel routers and stayed connected until I turned it off.I am confused

The 169.x.x.x addresses essentially mean no dhcp lease was offered/recieved. Does the Windows laptop also get the 169.x.x.x address? If so, have a look at your router configuration. Considering the power loss, and multiple machines having problems, I'd start at the router and work back to each machine.

Which model and what firmware are you running on the Buffalo? Some things to look for, Have you tried simply rebooting the router or looking at the Auto channel setting?
Good luck. ;-)

Similar Problem with timeout or something - 64 digit password??

For about the last month I have a similar problem. My wireless, when it connects, stays connected for about 15-20 minutes and then disconnects. The password that then shows up in the network manager is a 64 digit password. I have no idea where it has come from. My password for the router/wlan is only 16 digits.
If I play around long enough I may, or used to be able to, get it to connect again, normally after a new boot. Then again the same problem after 15-20 minutes.
At this point I just look for a cable.

F9 had been my best wireless experience until this complication. Yes, sad to say but windows still connects without problems with the router/wlan.

I suspect a Fedora update has changed something for the worse but with my limited experience I do not know where to look. The notebook is an Fujitzu Siemens Amilio Xi 2550 running with Fedora 9. Here is my iwconfig:


[root@localhost ~]# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11abgn ESSID:""
Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated
Bit Rate:54 Mb/s Tx-Power=15 dBm
Retry min limit:7 RTS thrff Fragment thr=2352 B
Encryption keyff
Link Quality=100/100 Signal level:-45 dBm Noise level=-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

pan0 no wireless extensions.

The face symbol should be a colon????

Up until this last month this notebook had worked perfectly. Too many Hotspots, Airports, no idea.

I'd be very grateful for any tips.

Namaste,

Kevin Tough

Kevin, I was never able to find the problem with my system. I replaced the firmware on my router to Tomato. It is now the best computing experience I have ever had in my home. Good luck

Any ideas on the 64 digit password...

Hi Trailer8713,

do you or anyone reading this post know where the passwords are saved. I'd like to know what is going on with this password issue.

My windows machine from the company I am working with works fine so changing the router firmware (if I can correctly) will be one of the last options.

Namaste,

Kevin
