Lost wireless connection when upgraded from 9.04  to 9.10


I was running Ubuntu 9.04 with no problems all, but when I  upgraded
to 9.10 I lost wireless connection (Ethernet works fine).

 When I run ifconfig
 I find just two interfaces
eth0      Link encap:Ethernet
 lo        Link encap:Local Loopback

when I run  iwconfig I get

lo        no wireless extensions.



eth0      no wireless extensions.



pan0      no wireless extensions.


BUT

I found all of the interfaces in 70-persistent-net.rules  file


 KERNEL=="eth*", NAME="eth0"



KERNEL=="wlan*", NAME="wlan0"



KERNEL=="eth*", NAME="eth1"
