When WiFi doesn't connect I have to shut down then turn computer on again 2-3 times

[slayr007]

Does Anyone have any Idea how to fix this problem.
It'd be much appreciated.

is it an atheros card?

If your card is identified and appropriate drivers laoded, then i assume its a problem with NetworkManager - the UI, whihc allows you to connect to a listed wireles..

Here's a old fashioned method.

$sudo pkill NetworkManager
$sudo dhclient -r eth1 #Or wlan0 depending on your card
$sudo iwlist scan
#This gives a list of wifi's available
$sudo iwfconfig eth1 essid <essid-name> key <key if any>
$sudo dhclient eth1

eth1 can be replaced from the device name listed with sudo iwlist scan

Hope this helps!

It is an Atheros Card

[slayr007]

are you sure that will work?:
$sudo pkill NetworkManager
$sudo dhclient -r eth1 #Or wlan0 depending on your card
$sudo iwlist scan
#This gives a list of wifi's available
$sudo iwfconfig eth1 essid <essid-name> key <key if any>
$sudo dhclient eth1

well, give it a try, u wont lose anything, restart will bring back NetworkManager anyways..

I have the same problem on an Acer 7520 with an Atheros card, instead of re boot, try : sudo rmmod ndiswrapper and sudo modprobe ndiswrapper.
It's not ideal, but it works for me, still am looking for a definite fix.

Good luck

It's problem NOT only in Network Manager, or only in Ndiswrapper drivers...

My issue is:

• turn off driver ( # sudo rmmod ndiswrapper )
• remove wireless network in [ RMButton menu at NM icon in tray > Edit Wireless Networks ]
• turn driver on ( # sudo modprobe ndiswrapper )

Sometimes I've just need to on/off driver.
It shakes me, I didn't like that, but this is Atheros...

Sorry for my poor Eng
