Network problem
in [Debian]
|
From: Lauri Lehtinen on 15 Feb 2005 10:50 Hi, I am having problems to get my network/internet connection to work as it should. I have D-link DWL-AG520 wireless card and I'm using it to connect to my Apple AirPort Express Base Station which is connected to my internet connection. I have iBook that is connected to the same AirPort and it success to connect to internet just fine. The problem is that I can't get my desktop with debian to connect to internet. All that I can think of is correct. I get following from ifconfig ath0: --- ath0 Link encap:Ethernet HWaddr 00:0D:88:55:D1:75 inet addr:130.234.193.60 Bcast:130.234.255.255 Mask:255.255.255.0 inet6 addr: fe80::20d:88ff:fe55:d175/64 Scope:Link UP BROADCAST ALLMULTI MULTICAST MTU:1500 Metric:1 RX packets:13709 errors:178 dropped:0 overruns:0 frame:178 TX packets:101 errors:1 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:199 RX bytes:1483252 (1.4 MiB) TX bytes:6144 (6.0 KiB) Interrupt:18 Memory:e89bf000-e89cf000 --- and the following from iwconfig ath0: --- ath0 IEEE 802.11g ESSID:"Apple Network 0ac786" Mode:Managed Frequency:2.412 GHz Access Point: 00:11:24:0A:C5:87 Bit Rate:36 Mb/s Tx-Power:50 dBm Sensitivity=0/3 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=47/94 Signal level=-48 dBm Noise level=-95 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:1 Invalid misc:1 Missed beacon:0 --- and those seems to me just correct. But with these when I try to ping -I ath0 130.234.193.58 (AirPort's IP) I get: --- ping: sendmsg: Operation not permitted --- I don't know what causes this. And so I can't connect to internet and/or ping the router. As you see I'm not using any encryption. The ESSID is correct and so is the Access Point. KWiFiManager is showing ULTIMATE signal strenght and all seems to be ok, but still I can't connect to internet. I have set the IPs and such manually to /etc/network/interfaces. When I set AirPort to give IPs to its clients and set dhcp on from the /etc/network/interfaces and trying to set ath0 up using ifup ath0 I get following errors: --- Internet Software Consortium DHCP Client 2.0pl5 Copyright 1995, 1996, 1997, 1998, 1999 The Internet Software Consortium.

No working leases in persistent database. Starting the Firestarter firewall: done. Exiting. Failed to bring up ath0. --- And again my iBook connects just fine. What should I check or do to fix my connection to work? What is wrong with my setup or what seems to be suspicious? What other info do you need? Any help is appreciated! I have madwifi drivers for the DWL-AG520 and they modprobe(modprobe ath_pci) without any errors and I can see the needed modules in lsmod. Needing help!
