| Internet gets disconnected with two wireless connections
Hi
I have lenovo R60 laptop with inbuilt wireless capability. I am able to connect to wirelessrouterA with the inbuilt wireless and browse internet.
I am doing a testing project, whereby I need a connect a wireless USB adapter and connect to wirelessrouterB. This wirelessrouterB is not connect to internet.
Once I connect the wireless USB adapter, I am not able to go to internet. If I remove the usb adapter internet is working fine.
Any idea why is this happening and how to overcome this.
WirelessRouterA - 192.168.1.254
WirelessRouterB- 192.168.0.1
Cheers

| Well - you stated that wirelessrouterB has no internet - therefore connecting to it with the USB will mean you can't get to the internet.
Seems to be working as you expect it to and have it set up to do.

Windows typically uses the more recently connected router for its routing. And since B is not internet connect, that won't work. If you know how to use the "route" command to manipulate routes, you might be able to get it to work as you want. Or, if you connect first to B, and later to A, it might work.

Well, ok. When I read it I understood it to be something different that those that have responded so far, so I'll chip in my 2 cents.
I think he wants to have the Internet connect on routerA and then be able to, at the same time, hook up to network devices on routerB. Or he may even want to have devices on routerB be able to use his computer to get to routerA and the Internet.
Ok, therefore I suggest he try ICS, 'Internet Connection Sharing' with in Windows. And then he could use both network cards at the same time.
Anyway, that is my guess.

Re: Internet gets disconnected with two wireless connections
DHCP on WirelessRouterB is probably giving your PC a default gateway to itself (and probably also as nameserver), and your PC uses the first matching route it finds to connect to anything. So if the default gateway to 192.168.0.1 falls before default gateway to 192.168.1.254 in routing table, your default route to the internet hits a dead end at 192.168.0.1. You do NOT need a gateway to connect to local network (LAN) 192.168.0.1 (that uses arp).
So for your wireless connection to WirelessRouterB use a static IP and netmask for your PC within the 192.168.0.x network, but outside of its DHCP assigned range, with no gateway or DNS for that interface. That way your PC should still be able to use its WirelessRouterA default gateway and DNS.
And make sure that the wireless channels on the 2 routers are set at least 5 channels apart (1 & 11, 1 & 6, or 6 & 11), so both do not splash each other with spread spectrum frequencies.
Do NOT enable ICS on that PC. If you want the 192.168.0.x network to be able to reach the internet through this computer, you would need to give WirelessRouterB a different 192.168.0.x IP, disable WirelessRouterB's DHCP, and let ICS automatically assign the IP for the PC's USB wireless (which would end up as 192.160.0.1 and would do DHCP for that LAN). |
