Default gateway changing after resuming from Sleep/Hibernate
I have had a problem with internet connection being lost on a wireless
connected netbook after resuming from sleep/hibernate.
I have traced the issue down to the default gateway being changed after
resuming.
Doing a network repair or NIC disable/enable doesnt help - only a
restart will correct the problem.
The wireless NIC is setup for DHCP, the wired NIC is setup with a fixed
IP , subnet mask and default gateway for a different network.
With wireless networking after resuming from sleep , "ipconfig -all"
shows the correct IP address & DHCP server but the default gateway had
been changed to the value for the wired NIC.
Changing the wired NIC setup to DHCP gives a workaround for the problem.
Anyone assist in why this error is occurring and a proper solution ?

Did you try "ipconfig /release" and "ipconfig /renew" ?

Correction to my OP:
"ipconfig /all" shows the correct default gateway
"route print" shows the incorrect gateway
I can correct the default gateway by doing a route -f, ipconfig /release
, ipconfig /renew
But I still have incorrect active routes in the routing table.
I dont seem to be able to use "route delete" to remove these.
ie route delete 192.168.0.0
I have worked around the problem by removing the fixed IP address in the
wired NIC.
But I assume it shouldnt work like this !

Why do you want two default gateways? Which one do you expect to be used?

The one specified for the Ethernet connection when he's connected by
Ethernet, and the one specified for the Wi-Fi connection when he's
connected by Wi-Fi. Presumably.

The way I read the OP was that the wired connection was not an alternative
to the wireless one for general network/Internet access but a separate
connection to a LAN - he says it is for a "different network".
If they are indeed alternatives which are not supposed to be used together
then they should both be DHCP so only the active one has IP settings at
any given time and, as per his later post, he has correctly fixed it.
If my reading is correct and the connections have different purposes the
wired one should not have a default gateway specified.
Having two default gateways at once doesn't really make sense. Many OSs
will not even permit it.

The 2 networks are not used at the same time, wireless at home, wired at
work where the network isnt DHCP.
Shouldnt the settings for the 2 NICs be completely separate and work
independantly ?
Why does it all work as expected until after a hibernate ?

Some drivers are buggy and don't reinitialise their hardware properly
after they've been suspended or hibernated.

Okay I'll go with that, always hope of a new driver !
I've learnt something anyway, interestingly ipconfig gives different
values from route for the default gateway after suspend.

Which ones would they be and on which operating systems?
Never trust what you read on Google or what you see people
posting about other unrelated problems! Your problem is that
when you are asked to explain anything you post, you don't
seem able to - not just in this newsgroup.
Release and renew will not fix the problem mentioned and if
you knew anything about computers it would help. Most that
do have already tried various commands.

Mine doesn't. So you do have a fault or incorrect setting.

If the OP did not have a connection to his router/AP how did he get his
route print to show the gateway?
I don't have an XP machine available at the moment but my Vista machine
has the same type of setup as the OP and if my wireless card is unable
to connect to my router no Gateway is shown in the Active Routes however
the ethernet nic Gateway is always shown in the Persistent Routes. If my
wireless card does connect to my router then I have a Gateway shown in
the Active Routes and a different Gateway shown in the Persistent
Routes. If I return my ethernet nic settings to DHCP then no Gateway is
shown in the Persistent Routes.
So is the OP confusing the Active and Persistent Gateways?

I'm just reporting what the route print command gives me in a command
window.
There is not a separate output from the route print command for each NIC.
OS is Windows XP Home .
Will cut and paste actual output later ( newsgroups done from a separate
machine !) in case it is of interest.
Not an expert in this area, just enough knowledge to guess that the
problem might be in the routing/DNS area and found a value which changed
after recovery from sleep.

This is what I get albeit Vista. I have deleted the Metrics column to
get it to fit.
