Wireless LAN problem

[Guest Monky]

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

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

with wlan0, this data is consistant as well:

 

route

Now when i ping the router is the part i dont understand:

 

ping 192.168.0.1

ping: sendmsg: Operation not permitted

 

--- 192.168.0.1 ping statistics ---

4 packets transmitted, 0 received, +9 errors, 100% packet loss, time 3078ms

 

Some things to consider : wep encryption is disabled on the router side. 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

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 ?

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.

Hi

 

From 192.168.0.3 icmp_seq=1 Destination Host Unreachable

ping: sendmsg: Operation not permitted

Assuming the firewall is turned on, try:

 

service shorewall stop

 

as root

 

cheers

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.

This thread is aaaaggesssss old, the guy obviously nevr returned - hence his post count of 1.

 

besides, now i woulda told him to get ipw2100.sf.net, the proper driver....

[JonEberger]

good call. i never even thought to look at the date or the post count.
