Wireless problem. Fedora 7


Hi.

I recently installed Fedora 7 with KDE on my dell insp 500m

Now i can't make the Wireless card work.

The firmware is installed (ipw2200 3.0.9)

When i open KNetworkManager it shows no wireless networks but wireless is enabled.. I know there's about 5-10 networks in this area and my desktop computer shows all of them (trendnet usb wlan adapter)


Anyone know what might be the problem?

Thanks in advance

Hi,

If you could specify the exact model of the card, it would be easier to help you.

try using the console ("ifconfig -a" ; "iwconfig" and "iwlist scan") If you find no network adapter, my guess is that you'll have to find an appropriate driver for it.

there are an a number of things that can cause problems like this, but I need more info to know what it might be

does the card show in the hardware tab of the network config tool 'system-config-network'?
is the driver loading at startup?
what do you get when you run ifconfig and iwconfig?

I assume that this means it's an Intel Pro Wireless 2200 v3.0.9
that was one of the options when this was sold as a new system

but I guess you never know

The Network card

The card is actually a Intel PRO/Wireless LAN 2100 3B, but i checked and i have firmware for that as well (ipw2100 firmware 1.3.8).

When i type iwconfig i get:
lo No wireless extensions

eth0 No wireless extensions


eth1 unassociated ESSIDff/any Nickname:"localhost.localdomain"
Mode:Managed Channel=0 Access Point: Not-Associated
Bit Rate=0 kb/s Tx-Powerff
Retry limit:7 RTS thrff Fragment thrff
Encryption keyff
Power Managementff
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

When i type iwlist scan it says:

lo interface doesn't support scanning
eth0 interface doesn't support scanning
eth1 "no scan results"

When i type ifconfig -a i get:

eth0 Link encap:Ethernet HWaddr 00:0D:56:77:21:AE
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

RX bytes:32522384 (31.0 MiB) TX bytes:32522384 (31.0 MiB)



It shows up in system-config-network as eth1 but it's deactivated, when i press activate, it says that i couldn't set up the ip.

Hope it helps.

That's too bad, the ipw2100b is slow, (I hate hacking into a b wireless network, easier to get caught). Anyways, you need to install the ipw2100 firmware as the ipw2200bg is not the same. When you unpack the ipw2100 source, there should be more than one file. My ipw2200 firmware version 3 was a .gz file. So I gunzipped it and it would not work, there was only one file, eventually I figured maybe I should run a tar command on it even though the word .tar never appeared anywhere, so I ran "tar xf ipw2200" or whatever, and the damn thing split into four files, I copied them to /lib/firmware in my Debian testing.
I like my Debian lean and mean so I only installed "network-manager" not "network-manager-kde", so I went to setting/network_&_internet/network_settings and highlighted my wireless interface and clicked on "configure_interface", a pop up showed up and I put in the relevant information and made sure it was on auto/dhcp and clicked OK, then at the bottom of the network configuration window I clicked "apply", a few seconds later an IP address showed up in the interface's line and I was surfin'.

Yeah the 2100 is slow and it doesn't support packet injektion, but the laptop was free and i use my 2nd laptop for hacking WLAN etc.

I am pretty sure that i have the 2100 firmware installed, at least there's files named ipw2100 in /lib/firmware/

As long as they end with .fw extension. But that is pretty much all I had to do was unpack the firmware and copy 3 of the 4 files (license not necessary) into /lib/firmware and reboot before tying to configure it. I originally set it up at work where there was non-encrypted networks, so all I did was highlight eth2 which is my wireless interface and select "configure interface", then just hit the manual radio button to have it think I was making changes, then just hit the auto/dhcp radio button to bring it back to auto for the "apply" button on the main window appear.
When logging into an encrypted networks, I was forgetting to change the key type from ASCII or whatever to HEX before I got it properly configured as most keys are HEX.

Well.. The firmware is installed..i believe i configured the device properl,buti still can't see any network.. when i get to a place with a net cable i think i'm gonna download kismet or WLAN Radar and see if i get anything through those..

Anyway, take a look at this:

When i boot the eth0 and eth1 fails, obviously because i have no active network connection. it display this msg for eth1 (wireless):

"error for wireless request "set frequency" (8B04): SET failed on device eth1: Operation not supported.

Anyone know what that might mean?

Apparently, Fedora has their own version of the firmware, I showed this place to someone else earlier today who had the ipw3945 or something and could not get it happenin' in F7, that person turned around and asked me where I wanted the six pack of beer delivered.

Oh!
And that error has something to do with not being able to access or configure for the channel your router's on. Might want to turn off all security features on the router and see if it will connect with "key off" after removing and reinstalling the module/driver like so:
#rmmod ipw2100
#modprobe ipw2100
#ifconfig eth1 up
#iwlist eth1 scan <---to see if it picks up area wireless networks

An IPV6 issue?

Check your "ifcfg-eth1" file in /etc/sysconfig/network-scripts, networking/devices and /profiles to make sure there is no comment like "IPV6=yes" In fact, I'd add the comment "IPV6=no". Also, check your "dmesg|less" output for comments that may reveal what is going on - especially comments related to "IPV6" routers". Even when you get your nic working, you may encounter a problem using Firefox. There is a line in the configuration regarding "IPV6" that is sometimes enabled. In most cases not good. To fix this problem enter "about:config" the into the address bar in Firefox. Then, if you enter "IPV6" into the search bar within and at the top of the config window the offending line will be displayed. Highlight the line and hit enter. It should toggle to disabled.

Otherwise, I'd ensure you are using the appropriate driver for your card.

Good luck.

How?

Fastest way is to rely on other folks experience. There is a wealth of information to be found using google. Just enter your card information and the word driver for starters.

Good luck.
