hello i have got an Acer Aspire 5536 running Peppermint 5 and over the last week when i login sometimes i get no internet connection,other times it just drops out on me,my Apple pc upstairs has no problem,i thought it was because i did the sky shield settings to over 18 and i have now stopped the shield running,i phoned sky and they tested the line and said all ok it might be my laptop,any ideas please?
thank you.

Funny you should mention that...

I'm in a government building, today -- probably halfway around the world from you -- and I have the same prob.

In my case, it turned out to be the WiFi channel they were using, e.g. channel 1.  Switching to a WAP that was using channel 6 took care of the bad/sporadic/sometimes non-existent connection.

I've had the same prob at my abode.  Channel 11 works best there.

Without knowing more about your situation, that would be my suggestion -- try changing channels.

I'm back with the feds again, today.  The WiFi connected right away (channel 6).  Yay! 

I was *thinking* about something else, that may or may not apply.

I'm a WiCD fanboi, so I don't run the NM UI.

Most of the time, in WiCD, I use the 'IOCTL' backend -- seems to be working fine, on this WAP.

Other times, when I'm on the trot, I need to switch the backend to the 'External app' (original), so called.

AFAIK, by default, Ubu's NM WiFi scheme uses the external 'ifconfig' & 'iwconfig' to query network information.  This makes NM a bit slower and more CPU intensive than the 'IOCTL' backend, but it doesn't require any third-party libraries.  Supposedly, this makes NM more stable for some setups.

Personally, on the equipment I run on my LAN -- and most places where I'm a guest -- 'IOCTL' works best.

Anyway, I'm not suggesting that you try WiCD.  It's NOT OFFICIALLY SUPPORTED.  I'm just throwing the idea out there, that it's possible that your setup doesn't like 'ifconfig' & 'iwconfig'.  My home setup certainly doesn't.  It's constantly connecting/disconnecting, even on a hardwire connection.

That said, I don't even know if you can add the 'IOCTL' backend to NM -- It's been so long since I've used it.

Maybe you can set it in the prefs.

Don't mean to confuse the situation... just burning off some nervous energy here.   ;)

OK, try this...

Open a terminal and run:
Code: [Select]
sudo gedit /etc/modprobe.d/ath9k.conf
when a BLANK file opens, add a single new line that reads
Code: [Select]
options ath9k nohwcrypt=1
SAVE the file.

REBOOT to test.

if you still have problems .. post the output from:
Code: [Select]
lsmod | grep wmi

So does that mean it's still dropping the connection ?
