Hi,

My PC is connected to two networks, wireless and physical. When I'm connected to wireless only, I'm able to access internet. But when I'm connected to both networks, windows is trying to connect to internet using physical network connection. Is there a way to force windows to connect to internet using wireless when both networks are connected?

Thanks
Suneel

try this

open up a command prompt (start > run > type "cmd" without quotes and press enter)

at the prompt type "ipconfig /all" (no quotes and note the space between ipconfig and /all)

look for your wireless connection and take note of the number following "default gateway"

now in the command prompt type

"route add 0.0.0.0 mask 0.0.0.0 <ip of your default gateway>" and press enter (again...no quotes and where <ip of your default gateway> is put the address that was listed in the ipconfig step next to the default gateway section)

see if this makes a difference

Thanks for the fast reply. This is what I got:

C:\Users\suneel>route add 0.0.0.0 mask 0.0.0.0 172.16.200.1
The route addition failed: The object already exists.

That didn't help either. It also took away access to physical lan network. So added it back.

ok type "route delete 0.0.0.0 mask 0.0.0.0 172.16.42.254" and press enter

then type "route add 172.16.42.0 mask 255.255.255.0 172.16.42.254"

having two cards active and working is doable..it's just difficult as there's no real way to set a preference...what we're trying to do here is force routing to follow the path we want

0.0.0.0 with a netmask of 0.0.0.0 basically tells the computer to send any traffic that it doesn't know a specific destination for to go over the suggested route...so if we tell your computer to route all 0.0.0.0 traffic over the wireless card then anything destined for a network that it doesn't know about should go that way (such as the internet)...the problem is that when you connect an interface that has a default gateway on it it will automatically create the 0.0.0.0 route so that it doesn't have to add other such routes


what does the wired lan connection plug into? a router? do all the other devices that plug into that router have the same ip subnet? (172.16.42.x)

Tried that. Able to access internet over wifi. But lost access to physical network. So had to add 0.0.0.0 mask 0.0.0.0 172.16.42.254 again to gain access. Then I lost wifi.

what does the wired lan connection plug into? Not sure. It is connected to a corporate network. So don't know where the wire goes to. (Probably a router)
do all the other devices that plug into that router have the same ip subnet? (172.16.42.x) Don't know.

Thank you very much for your help. I thought this would be common problem and would have an easy solution.

ok...you said the magic C(orporate) word... you need to talk to your IS group about this

there are VERY few instances that i can think of (Being in corporate IS)where i would let someone attempt to do what you're doing unsupervised at work....
