[Bug 429070] Re: Upek Fingerprint Reader does not work

[Aryan Pourbaghery J.]

Well, glad to hear you are at least up and running with your fingerprint sensor. yet for the mentioned issue I'd just as soon ask whether you are sure if it is a wireless functionality loss/malfunction or rather merely a slight issue of display with the UI. Odds are most probably against the former and hopefully for the latter! however, since you do not have access to the network manager icon on the taskbar panel (and as for the worst case scenario I would assume you do not have access to the launcher provided in the main menu>Administration>NetworkTools and System>Preferences>Network Connections  either! Cause if you have, then it is a lot easier to track down the problem.), we should first carry out a couple of diagnostics. 
While you have the finger print login enable do the following:
$ ifconfig
The result is similar to 
eth0  Link encap:Ethernet ....

lo    Link encap:Local Loopback ....

wlan0 Link encap:Ethernet ....
or use
$ netstat -i
In the results for either commands, see if there is any one named wlan0 like the above or sth similarly named(in case you have more than one wireless adapters you should be looking for more than one "wlan"s quite certainly in order of wlan0,wlan1,...).
if so then you are blessed. There is probably nothing wrong with your wireless lan and it's just a UI bug.
if not then try the following:
$ sudo ifconfig wlan0 up
or 
$ sudo ifup wlan0 
then check up again if your wireless is up running via ifconfig or netstat as above.
if your wlan is up then check your connectivity via
ping www.google.com
if the result is similar ,in appearance, to 
64 bytes from hb-in-f104.1e100.net (74.125.87.104): icmp_seq=1 ttl=50 time=341 ms
then everything is fine! you are already connected. 
if not do the following and repeat the above steps.
$ sudo /etc/init.d/networking restart

No good news yet? then just check the results of the below commands and let us know about it all, so we can dig alittle bit more in:
$ sudo nano /etc/network/interfaces
or
$ sudo vi /etc/network/interfaces

and
$ sudo nano /etc/resolv.conf 
or
$ sudo vi /etc/resolv.conf
