problems with internet access

[jon1234444]

I'm running the latest version of gbridge on windows vista home premium 32bit. I connect to the internet on my main computer through a wireless connection.

everything works fine, unless something disrupts my wireless connection. say I turn on the computer, everything works great, and then I lose connection to the wireless network. after windows reconnects, I am unable to access the internet. it says I'm connected to the wireless network, I just can't do anything. I've found the only way to fix it is to either restart the computer or disable the gbridge vpn and then re-enable it.

it seems windows gets confused about how to access the internet after briefly losing the wireless connection. any ideas how to prevent this?

thanks!

How long have you waited after wireless restore the connection?

Can you pm me the output of follwoing commands when you experience the problem?

1. under command window, type "ipconfig /all"
2. in command window, type "route print"

Thanks!

I have had the same issue, and I think I know what the issue is. When the wireless connection drops, the routing table changes the default gateway to the VPN network address. Therefore, gateway traffic is routed to the VPN. As a workaround, I disable and re-enable the wireless connection, which usually works. Once in a while, the wireless cannot reconnect, so here is what I do when that problem happens:

1. Exit gbridge.
2. Open "network connections" right mouse click on the gbridge adapter and disable it
3. Wait a few seconds as the default gateway resets to the wireless connection. Test your connection
4. enable gbridge adapter
5. Restart gbridge

Although this is laborious, it does avoid a reboot. Perhaps there is a way to fix this in the next software update; to avoid the default gateway going to the VPN network.

Here's my route print when things are working good:

Good analyse!

I don't understand why Windows doesn't use
0.0.0.0 0.0.0.0 192.168.101.1 192.168.101.229 25
as default gateway in the problematic case you present. Note that Gbridge's metric (5000) is purposely set to much higher than the other interfaces (25 in this case).

Thanks for debuging this!

BTW, are you running vista sp1? there is a MS support kb article may be related to this:

Do you mind id I piggy-back ? Outpout from route print on my system (Windows 2000 Pro) has Metric=1 on all lines (including GBridge). I've sometimes suspected, and can someone confirm if rightly so or otherwise, it to be a bug in the version of the 'route' command in Windows 2000...

I think I remember there is another command (probably 'net' something...) that also gives 'route' details. Can someone again refresh this old crank's memory ?

Thank you

Which release you are running on your windows 2000 pro?

[Czerno]

Which release you are running on your windows 2000 pro?

It's Windows SP4 fully patched at Windows update.
Or are you asking which release of GBridge ? It says 1.0.0.1180.

thank you !
