Guest Monky Posted July 6, 2004 Report Share Posted July 6, 2004 I have mandrake 10 (with kernel 2.6.3), centrino wlan 2100b card and try to use it with ndiswrapper v0.8. and wireless tools v0.6 (everything have compiled cleanly). I can successfully get an ip from my wireless router by dhcp. But I can't ping it. If i use the wired network interface, i can get an ip address (also via dhcp) and as well ping the router (and access the internet as well). Here is some sample output from various shell commands : iwconfig wlan0 wlan0 IEEE 802.11b ESSID:"Blitzz" Mode:Managed Frequency:2.457GHz Access Point: XX:XX:XX:XX:XX:XX Bit Rate:11Mb/s RTS thr:1600 B Fragment thr:2344 B Encryption key:off Power Management max timeout:0us mode:All packets received Link Quality:0/100 Signal level:-53 dBm Noise level:-256 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 (Is the Link Quality:0/100 normal with intel centrino under linux??) if i use the eth0 interface, i get: route Destination Gateway Genmask Indic Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 ifconfig eth0 eth0 Lien encap:Ethernet HWaddr 00:A0:D1:D8:41:2C inet adr:192.168.0.2 Bcast:192.168.0.255 Masque:255.255.255.0 adr inet6: fe80::2a0:d1ff:fed8:412c/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:9927 errors:0 dropped:0 overruns:0 frame:0 TX packets:8380 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:5598603 (5.3 Mb) TX bytes:1118563 (1.0 Mb) Interruption:11 Adresse de base:0x1000 with wlan0, this data is consistant as well: route Destination Gateway Genmask Indic Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 wlan0 default 192.168.0.1 0.0.0.0 UG 0 0 0 wlan0 wlan0 Lien encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX inet adr:192.168.0.3 Bcast:192.168.0.255 Masque:255.255.255.0 adr inet6: fe80::204:23ff:fe7a:fc5/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:730 errors:0 dropped:0 overruns:0 frame:0 TX packets:100 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 RX bytes:73932 (72.1 Kb) TX bytes:15796 (15.4 Kb) Interruption:11 Mémoire:d0001000-d0001fff Now when i ping the router is the part i dont understand: ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

Works under windows. Power is turned ON on the wireless card. When i boot, i get a message telling me that wlan0 interface could not be initialized successfully, looks like : "no link present. check cable?". My /etc/sysconfig/network-scripts/ifcfg-wlan0 has "TYPE=Wireless". Please also note that my mac addresses are not really XX:XX:XX:XX:XX:XX. Sorry if some output has french text in it. Any help would be appreciated, because i am clueless about that. Thanks Quote Link to comment Share on other sites More sharing options...
Gowator Posted July 6, 2004 Report Share Posted July 6, 2004 hi and welcome (Is the Link Quality:0/100 normal with intel centrino under linux??) Erm dunno, I use kwifi on my laptop ... this has a signal strength/quality... it shows IP etc. graphically so Its quite nice to have running and then fallback on ! what seems to be happening is the default route is somewhat confused between the wired NIC and the wlan... a quick fix might be to ifdown eth0 ifdown wlan0 ifup wlan0 then ifconfig -a and route (just to check) then later you might wanna play with the link-detect on the wired NIC to stop it coming up if no cable is plugged in ?

iphitus Posted July 6, 2004 Report Share Posted July 6, 2004 Gowator: At present the ndiswrapper drivers do not implement link quality and other niceties like that for the simple reason they are not part of the ndis spec and are not documented. Monky: what model laptop do you have? Brand AND model. Quote Link to comment Share on other sites More sharing options...
Guest drz Posted September 24, 2004 Report Share Posted September 24, 2004 Hi From 192.168.0.3 icmp_seq=1 Destination Host Unreachableping: sendmsg: Operation not permitted Assuming the firewall is turned on, try: service shorewall stop as root cheers drz Quote Link to comment Share on other sites More sharing options...
JonEberger Posted November 25, 2004 Report Share Posted November 25, 2004 if you're running shorewall (mandrake firewall), then go to /etc/shorewall and vi the interfaces file. you can change the setting on wlan0 from local to net and that has helped me out. also, i just went through the net detection gui in mcc. that never hurts and it perfectly detected my card.
