Fedora13 wireless network connection failure-Linux general technology-Linux technology and application information, the following is a detailed description. I came across a very strange thing. I'm a DEll instance on the iPhone 1545, and the wireless Nic is broadcom BCM4312 802.11b/g LP-PHY (rev 01). I installed the driver according to the instructions on the Internet, the ifconfig wlan0 up command correctly loads the wireless network card. The output obtained by using the ifconfig command is as follows:
Link encap: Ethernet HWaddr 70: 1A: 04: 68: 96: A2
Inet6 addr: fe80: 721a: 4ff: fe68: 96a2/64 Scope: Link
Up broadcast multicast mtu: 1500 Metric: 1
RX packets: 217 errors: 0 dropped: 0 overruns: 0 frame: 0

Collisions: 0 FIG: 1000
RX bytes: 20675 (20.1 KiB) TX bytes: 6408 (6.2 KiB)
The command Output Using iwconfig is as follows:
Lo no wireless extensions.
Eth0 no wireless extensions.
Wlan0 IEEE 802.11bg Mode: Ad-Hoc Frequency: 2.412 GHz
Cell: Not-Associated Tx-Power = 20 dBm

Power Management: off
Vboxnet0 no wireless extensions.
Virbr0 no wireless extensions.
From the above, the NIC driver should be okay. You can find a lot of unencrypted and encrypted wireless networks. You cannot connect to an unencrypted wireless network on the GNOME graphic interface, or connect to an encrypted wireless network (I also have a password ), the worst thing is that when I connect to an encrypted wireless network, I lose my password, and then I don't even connect to it. I also call it a password. If I press the cancel button, the Network icon is a cross, I didn't even have a prompt for a wrong password. I thought I had filtered out my MAC address. When I went to KFC this afternoon, KFC had a strong signal, why is the link unavailable! I tried Aircrack-ng to crack WEP. I broke the encrypted WEP and can carry out injection attacks, but the link is depressing. Please let me know, thank you !!!!
