Hi

My wireless card
product: Wireless WiFi Link 5300
vendor: Intel Corporation
Died recently. It was working wonderfully. It later started disconnecting from networks and not it is not operable. I need a wireless card doctor to tell me what is wrong with it and how I can fix it.

When I right click on the wireless icon in the top panel in ubuntu I get

check Enable Networking
NO CHECK Enable Wireless (I cannot turn on)
check enable notifications

My ethernet is working

I tried

sudo ifconfig wlan0 up

I get the error

SIOCSIFFLAGS: Unknown Error 132

Here are some outputs

@ sudo lshw -C network

it look like your card is ok

and i would suggest you to boot up windows download WICD remove network manager install wicd and than try it again.

i had the same problem with network manager ones it worked other time was showing networking off and i couldnt switch it on so i installed wicd and didnt have even one problem since

Hi

I was searching around on the SIOCSIFFLAGS: Unknown error 132

I found some vague references to rfkill.

@ rfkill list
0: phy0: Wireless LAN
Soft Blocked: no
Hard Blocked:yes

It says my "hardware is blocked"

I presume you've right-clicked the Network Manager icon and verified Networking and Wireless are enabled.
A few links that might be helpful:

As I recall, /var/lib/NetworkManager/NetworkManager.state has a line about wireless... though I'm not sure these would qualify as "Hard Blocked" - that seems more like a switch...

I apoligize

This had nothing to do with ubuntu and everything to do with bad computer design

There is this little switch on the side of my computer that is not labled, that when I fliped it, my wireless card worked.

Thank you for your help. Sometimes it is that easy.
