Hello
I've an old laptop (Lenovo 3000N200) which was fitted with an Intel 5100 wifi card. It ran trouble free for years.
Lastly, the wifi card began to make huge transmitting errors and caught one packet on 1000.
As I was unable to get my hand on a mini PCI card that fit inside the laptop and runs well, I switched back to the original Intel PRO/Wireless 3945ABG it has when it left the factory.
Transmission problem are settled. Fine.
Now, as usual, the wifi link start on boot (it is set up in /etc/network/interfaces) and runs fine. But when I get back from sleep, the iwconfig shows :
Code:
lo no wireless extensions.
wlan0 IEEE 802.11abg ESSID:"Good ESSID OF the Wifi"

eth0 no wireless extensions.
The ifconfig shows :

but when I try to ping the default router :
Code:
root@biniou:~# ping 192.168.0.254

^C
--- 192.168.0.254 ping statistics ---
14 packets transmitted, 0 received, +7 errors, 100% packet loss, time 13071ms
I get this on syslog :
Code:
Jun 29 12:20:25 biniou dhclient: No DHCPOFFERS received.
Jun 29 12:20:25 biniou dhclient: No working leases in persistent database - sleeping.
which puzzle me because the ifconfig shows that the card has an IP address set up...
And the wifi LED on the laptop flashes like hell.
The only way I've to make it work is to do :
Code:
sudo ifdown wlan0
sudo ifup wlan0
Could you help me find what is wrong and how I can make it work again ?
Many thanks in advance for your help !
