Hi all,
Recently my wife's laptop has been experiencing some wireless issues -
slow performance, drop-outs and the like. We have numerous
wireless-enabled devices in the house and although we have the
occasional blip, none of the other devices seem to be affected to the
same extent, so I figured it was probably related to the laptop itself
and set about trying to figure out what the problem might be.
The laptop is a Toshiba Satellite L450-188 running Ubuntu 12.04 with
the LTS backport kernel from Raring. The original wireless card in it
is a Realtek RTL8191SE. I tried replacing it with the Atheros-based
card from my son's EeePC, but although the card was apparently
recognised, and the ath5k module loaded, the card was disabled:
jtait@mothership:~$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
rfkill unblock has no effect - no error, but the card remains hard
blocked. The wireless key (Fn-F8) simply toggles the soft block, and
the laptop has no hardware switch that I can see. There's a setting
in the BIOS that doesn't seem to have any effect. So I picked up an
Intel IWL4965AGN card on eBay for a couple of quid and tried that, but
the result was the same:
jtait@mothership:~$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
I've tried countless "solutions" on ubuntuforums and so on. Is it
possible that Toshiba have decided to lock the laptop down to a
specific kind of wireless card?

Hi,
My Acer laptop (intel Wifi card) suffered wifi probs on 12.04, never did
get to the bottom of it, but upgrading to 13.04 solved it! I know this
is not necessarily a solution but if you can pin down what has changed
between the versions it might help (I have to admit once it 'fixed
itself' I stopped looking!) if it helps ill post the output of some
helpful commands below, and if you want any other info I would be happy
to provide it.
