Hello,
I have a laptop using wifi, but the router limits each connect banwidth to 1 Mb/s.
Can I using wifi and ethernet at the same time to get 2 Mb/s bandwidth?
If you have 2 internet connection you can manually send some ip to the one and the rest to the other. What you need to do is remove the default route from the connection you do not want to be your main connection. you can then use the route command to send certain IP to the other gateway address. It tends to be a pain but you can for example surf on one and play games on the other. You cannot though download a single file faster.
