Wireless Switch Disconnects After Vista Sleep

Hi. I'm really frustrated at this and feel I've tried everything. I've been
searching all over the internet for help but to no avail - nobody seems to
have this specific problem.

I have just bought a new Sony Vaio VGN-NR11Z/S (2 GHz Processor - Intel Core
2 Duo T2750; 2 GB RAM; Windows Vista Home Premium 32-bit Version). It has an
integrated wireless switch on it and is running windows Vista. These two
things don't seem to agree with each other.

I boot up the laptop and the wireless connection works fine, I connect to
the internet straight away. I then put it to sleep in the way I used to using
standby on XP (closing the lid basically). When Vista comes out of sleep mode
I find that I can't connect to the internet, and the little light on the
wireles switch is off.

I diagnose the problem and it tells me to turn on my wireless switch, which
is odd as it is already on. The only way to get the internet working again is
to restart the computer. "ipconfig/renew" in command prompt says the media is
disconnected. Device manager says the device is working properly and
disabling then enabling it doesn't help. I've just installed the latest
driver (11.5.0.32) and that hasn't helped either. Changing power settings to
maximum performance does nothing as well, neither does turning the switch off
then back on again.

My wireless device is "Intel(R) PRO/Wireless 3945ABG Network Connection".
It's basically when I come out of sleep the computer can't recognise the
wireless switch, or it turns itself off even when it's in the on position.

Does anybody have any idea how i can fix this? This is my first Vista laptop
and I'm really frustrated

Why didn't microsoft just keep Standby as an option?

Thanks in advance.
 
You may want to modify the power settings. This search result may help.

As I said, changing the power settings doesn't help. I've been on that
website before but to no avail.

It seems as if vista just turns off my wireless switch of its own accord.
It's so frustrating.

I appreciate your help.
 
1. Could you check the default gateway and ipconfig after wake up from the
sleep and make sure Vista doesn't lose the default gateway.
2. You may try to remove IPv6 completely for a test (not just disable)
3. We had some similar posts before. You may want to check them. Please post

Hi. I managed to fix it. If anyone else with a Vaio has this problem, it's
probably because "Vaio Smart Network" was disabled, which is what I had done.
As long as that is open, the connection works after sleep.
Thanks for your help.
