Wireless Networking - Obtain IP vs Use the following IP

Default Obtain IP vs Use the following IP


In my Windows XP, WPA-PSK protected home wireless LAN (via router > cable
LAN) one laptop was having problems regaining internet access after
hibernating. I solved the problem by switching it's wireless TCP/IP setting
from
"Obtain an IP address automatically"
to
"Use the following IP address"
and
"Use the following DNS server address"

Question:
While the internet connection is now working fine, I suspect the laptop will
not see hotel access points? If so, is there a way to have both setups
simultaneously on this laptop? I mean have the laptop "Obtain IP address
automatically" and if unable to "find any network"?

Thanks.

Jeff

All your assumptions are right. You need to fix whatever problem you have
with obtaining a dynamic address at home.

Hi Jeff,

Switch your laptop back to "obtain an IP address" and check the status of
your IP address by typing ipconfig at a command prompt. To see more
details, type ipconfig /all.

Now allow the laptop to hibernate and demonstrate the problem. Check the IP
address again using ipconfig. If you lost the IP address during
hibernation, it will be 0.0.0.0. You can prevent this by using the
"alternate configuration" tab. Enter the static IP address and DNS settings
you used before in the alternate configuration tab. When the computer loses
it's dynamic address (the one it obtains automatically), it will fail-over
to this alternate address. You should still be able to access hotel access
points, because it won't use the alternate configuration unless it can't
find one automatically.

I hope this helps!

I just thought of another option that might help you.

Check the detailed properties of your wireless adapter by using the
configure button. On the advanced tab, there should be a list of
properties, one of which is power save mode. Disable this and it may
prevent your network card from losing the IP address. Hibernation sometimes
shuts down the power to network cards, and when that happens they often
don't maintain a dynamic IP address.

Default Re: Obtain IP vs Use the following IP

Dear Greg

You are very kind. Thanks for taking the time to help me.

On the advanced tab for the wireless adapter there is indeed a "Power Save
Mode" and it currently is set to "CAM" The other options to select from for
the Power save mode are: "Fast_PSP" and "Max_PSP" . Not sure which to
choose. (see below under BUT).

Interesting, on this screen there are also options to set
1. Network type - (set to infrastructure, which I hope means access point or
router)
2. Network address whcih I notice is blank!! ("Not present" selected).
Should that be so?

The other settings are of course Channel (1) and SSID (which is not the
default one).

BUT, looking at the other tabs there is a tab called "Power management" and
it gives the option to "Allow the computer to turn off this device to save
power" and it was selected! Sp I unselected it. That may well be it.

One more question if I may. On the TCP/IP "alternate configuration tab", I
entered the data as you suggested, including the DNS. It however also asked
for WINS which I left blank. Where do I get the numbers for WINS?

Ipconfig /all shows me that:

for Windows IP configuration:
- Primary DNS suffix is empty
- Node type is unknown
- IP routing Enabled is set to No
- WINS proxy enabled is set to No

for the wireless adapter
- DHCP is enabled
no mention of WINS

Are these correct?

Thanks.

Jeff,

You found the correct place to disable power management of the adapter.
Some adapters have this on a power management tab, while others list it as a
property. Good work - I hope this prevents your problem entirely.

Your alternate configuration is correct. The output of ipconfig that you
have below indicates that you aren't using WINS, so you don't need to
configure anything there. Good luck!
