can you bridge your home internet with a wifi connection?

So the idea make sense, but the it doesn't work from a technical sense.

You want your entire session state to route through the same path. So let's say you set up a route jumper that changes your default route to go out wifi then you do the easy thing and say every 5 seconds, have it route through your cable modem.

So you log onto gmail... actually wait now that I think about it, the backend wouldn't care that you're routing though different devices. The burden of truth is on your local HD as session state. So as long as your browser passes the session ID; that can come from different MACs (ie different routes).

This is the idea behind firesheep a TCP session state capture tool. If you own the session ID and send it to the endpoint, you can make it believe you are the real owner of the session.


So, to the op's original need, he wants to probably run bittorent and have it choose both paths so he gets the combined upload and download BW of each path.

The easiest thing to do is set up two bittorent clients and have one route through one path to wifi and the other to route through your cable modem.

Something like this. You're looking for windows application based routing.

Next, you'll need to make sure you can run your hardwired connection and wifi at the same time. IE: you may want to statically assign each interface an ip address. They need to be on different subnets so they have different gateways (aka: routes). ( Hopefully they are on different subnets since you'll have colissions if you have the same subnets for each interface but the gateways are the same IP. You'll just end up screwing things up since you'll have GW MAC conflicts. So, its best that each one be on a different subnet to make things easier. Make it happen if it isn't. Even if you're leeching other wifi, just set the range to be on a different subnet.)



Then you'd follow a guide like that to make that application route through the appropriate gateway. Yay done! Simple stuff man. Just basic routing.

route add is your friend.

By the end of this I want you to be able to calculate subnet ranges in your head!



Edit: Router Side Trick!
Oh yeah, you can also use AutoAP on the router side if your router is flashed with dd-wrt. It just takes all the avaialble SSIDs that you give passwords for (see lifehacker article on reaver (hint hint)) connects to them, runs a health metic to see their speed, then jumps onto them.

Since you're behind the NAT, you'll never notice, but AutoAP will keep jumping you around to the fastest Access Point. Works best in Apartments with a good cantenna.

That's for those who have only WIFI they want to use
