cannot connect to the internet after standby - have to re-boot

Hi

My friend is running WinXP and using a linksys wireless router.

When his PC comes out of standby mode it cannot connect to the internet. I
suspect because it loses the wireless connection to the router. He told me
the only way to re-establish internet access it is to reboot the pc.

Any suggestions on how this can be fixed?

Thanks for any info.

Interesting. Just thought I'd note a friend of mine (always a "friend",
no? :-) ) has a similar problem. I don't know if standby comes into
it, nor why with adsl he disconnects in the first place, but if he
disconnects from the net, he has to reboot before he can reconnect.
Don't know what hardware. It's on my list of Things to Do.

A simply .bat file:

ipconfig /release_all
ipconfig /renew_all

should do it.

I have no friends so I never see such problems. Any particular
wireless router? Any particular wireless client radio? Any
particular brand of computer? Any particular Windoze mutation (Pro,
Home, Media Edition, SP2?)

Are you sure it's standby and not hibernate?

There are 4 layers of "standby" on the typical PC. I'll assume the
mystery PC is a laptop so I don't miss any. Your job is to give your
soon to be former friend the bad news that he will need to disable
each layer, one at a time, until the culprit can be identified.

1. Power save on the wireless adapter. This is in the properties for
the unspecified wireless device.

2. System hibernate and/or standby. They're quite different and are
buried in the Control Panel under "Power Options"

3. Screen blanker. It may seem odd but I've found one laptop
(Toshiba A45-S515) that would kill the wireless connection when the
screen blanker kicked in. Don't ask me why. I don't know.

4. BIOS based power save. You'll have to dive into the CMOS to
twiddle with these. If running ACPI, they can be set by the Power
Options in the Control Panel, but it's a good idea to check them
anyway. In desktops, it's sometimes called the "Green PC" settings.

If your soon to be former friend doesn't want to go through that
exercise, you scan try this trick and see if it works:
Start -> Run -> CMD <enter>
IPCONFIG /RELEASE
wait about 10 seconds
IPCONFIG /RENEW
This sorta kick starts the wireless card and try's to convince it that
it should wake up and renew the DHCP lease. Another similar trick is
to find the wireless icon in the system tray, right click, and select
<disable> followed by <enable>. Don't do the "repair connection" as
it takes way too long to complete.

>Any suggestions on how this can be fixed?

Yes. Reduce the number of friends you know with computers and they
won't bother you with such questions.

In the future, it's a good idea to supply:
1. What you're trying to accomplish. (You did that).
2. What you have to work with. (You did that very badly).
3. What you've done so far. (You didn't supply that).

I find that annoying, because my icon disappears when I disable, so I have
to wander off to Network Neighborhood to enable it.
I put a couple of icons on the desktop for disable and enable, because I do
want to disable/enable my WiFi occasionally.

That doesn't take so long for me...

>>Any suggestions on how this can be fixed?

Get a different computer. My Dell would return to proper use very quickly
from either standby or hibernate. My Fujitsu recovers okay from standby,
but takes so long to come back from hibernate that it is faster to reboot.
This seems to have something to do with network connectivity, not
particularly WiFi.

Same problem here.
Motorola Cable Modem connected to Linksys Router WRT54GX wired (NOT
wireless) to two PC's running XP-SP2. One PC has Linksys Ethernet PCI
card. Other PC has built in port on ASUS A8N-E nvidia nforce4 ultra
motherboard. Firmware and drivers all up to date. Powersaving turned
off except for monitors. After an extended amount of idle time (not
sure how short, but two hours brings on symptoms) computers no longer
see internet. Repairing link doesn't work. ipconfig /release ipconfig
/renew doesn't work. Rebooting does work, but I'd hate to have to
reboot everytime I want to check email after a few hours away from the
machine. Any ideas? Thanks in advance.
