Laptop #1 is connected to the router via WiFi. Laptop #2 is too far away from router to be able to connect to them. I can create a access point or Ad-hoc if I am connected to the router via wired network. But Laptop #1 is not connected to router via cable, but via WiFi. Is it somehow possible to create acces point or Ad-hoc on computer, which is connected to router via Wireless? Any help is appreciated.
Generally, it is not possible to do this unless you have two wireless cards. For example, you could get a USB receiver for your wifi and then use the built-in WiFi card to create an ad hoc network.
I am not aware of any wireless cards that allow you to create an ad hoc network while connected to another network.
Another option would be to go with a wireless repeater (I've seen them as low as $60 USD) and they work quit well. Just place it towards the end of your network's range and they will rebroadcast the signal.
