Hello: I am running FC-4, and I have been trying to configure my wireless connection. Apparently Everything is all right: # Ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3128 errors:0 dropped:0 overruns:0 frame:0 TX packets:3128 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3770918 (3.5 MiB) TX bytes:3770918 (3.5 MiB) ppp0 Link encap:Point-to-Point Protocol inet addr:148.221.119.60 P-t-P:148.235.20.172 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:281 errors:0 dropped:0 overruns:0 frame:0 TX packets:314 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:189816 (185.3 KiB) TX bytes:43672 (42.6 KiB) wlan0 Link encap:Ethernet HWaddr 00:06:25:48:3C:17 inet6 addr: fe80::206:25ff:fe48:3c17/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:2089 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 ------- But when I try to connect, I get: [root@pauli gcovar]# ifup wlan0 Error for wireless request "Set Bit Rate" (8B20) : SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0... failed. ---------------------- Does anyone know what this error is and how to correct it? Any feedback will be appreciated. Teilhard.
