    Is there any way to connect to a WiFi router with your Android phone, and then share that connection, by using the phone as a hotspot?

    Like.. I know you can wirelessly tether your 3G connection.... but can you tether your router's WiFi connection...?

    The purpose of this would be to increase the signal further.

    Does anyone know what I'm talking about, or do I need to explain clearer?

    Actually, I think it may be possible with root. There are root apps that spoof all WiFi traffic through the phone.

    Not exactly the same, but maybe it could be tweaked by a developer

    Not sure if its possible, but my bet is NO. Signal repeaters use 2 antennae, one to receive and one to transmit. Cellphones only have one WiFi antenna, and these things can't receive and transmit at the same time.

    Ah! That makes sense, the way you put it. Yeah.. it can only do one at a time. Fair enough. OK. I thanked you.

    You can tether a wifi connection to a blue tooth connection using FoxFi. I have done this on a desktop PC that didn't have wifi, but did have a blue tooth adapter.

    Wifi modules most often have to be put into a different mode in order to work in one or the other modes of operation. Similar to a master/slave designation for a BT module (not exactly the same tho really). Point is even if the hardware is technically capable, chances are that the pins are pulled high or low accordingly such that you can't. Again all depends on the Wifi IC on each particular phone so it wouldn't even be economical to create an app really because there are just so many implementations of Wifi ICs.

    On the other hand, I'm pretty sure on my phone SGS3 I can tether by connecting to wifi then tethering it out through USB to ur laptop.

    I know for a fact that using certain linux modules (also included in android) you can route internet connections via IP tables any which way. I used to do that for embedded development by connecting my laptop to the internet via wifi then using the ethernet device on my laptop to be the DHCP server for my embedded system (running android/linux).
