Question

Recently it's repeated constantly !! Network is Disabled shown in the network icon, my OS ubuntu 10.10 .
While I'm surfing on the NET after a while (may be 2 hours or may be a day) it disconnect and then can't connect to WiFi anymore till rebooting the machine !!.
I've searched and tried a lot of solutions but no useful one seems to solve the probelm :(
here is one in this forum it's same problem explained there but can't solve as mentioned !,also every thread/question related to the problem found here I tried but no hope .
"Rfkill list all" command shows:

1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

even the Wireless button is switched on !
another command:

sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill

please help....any suggestion will be appreciated .

Solution

if rfkill list shows 1 is hardblocked: did you try running

rfkill unblock 1

that works for me (but in my case i have to run rfkill unblock 0 and rfkill unblock 2, the first is my wireless switch, the second is the wifi switch)

Can you add what kind of wireless card it is?

[wisdom]

can "lshw -class network" command be enough !?

[nilsonneto]

... ok - also to note (I'm sure you are aware of this already) - support for 10.10 ends in april. You might want to consider upgrading - this will also have a new kernel which might fix your problem.

@fossfreedom Thanks, I know that and am waiting the next release 12.04 while the two previous releases were uncomfortable for me ! they confused me a lot!

[wisdom]

nor of them was useful ! but still the first choice I didn't try yet....I'll feed you back.

[wisdom]

can't try now till it'll be disabled then I'll feed you back,Thanks.

[wisdom]

Sorry Mr.fossfreedom to be late, No one of above suggestions can solve the problem yet:( but the first not tried yet....here you can check the results of commands < uploadup.com/di-43PD.png > 4th suggestion disable the whole wireless card and can't reload it any more till reboot the machine :'(.

[wisdom]

Sorry, the 4th seems not to work :(, just the first choice is on ... will feed you back .

[wisdom]

I've tried your suggestion Mr.cfstras but it's still disabled !! :(

[wisdom]

Then with all these suggestions, what would be the problem ?? hardware compatibility ? or what ?

[nilsonneto]

the rt73usb is very flaky with the maverick kernel. My suggestion would be to investigate a later version of ubuntu to see if the later kernel fixes your issue. You mentioned you dont like unity - Look at my answer here for how to get your old desktop back again in 11.10. askubuntu.com/questions/58172/how-to-revert-to-gnome-classic

[cfstras]

what does rfkill list say before and after rfkill unblocking?
