Can we use an Android phone as a Wi-Fi repeater?

Imagine situation when you can access a weak Wi-Fi signal from a free hotspot (coffee shop) signal near window, but want to work in the middle of the room. Then we can put the phone on the windowsill to spread the signal over the entire home.

Is it feasible?

The answer is yes, there is an open-source project available that does exactly that.

To quote:

It is a software designed to help you by-pass Great Firewall of China (GFW). Different from similar softwares, it is designed to run as router instead of running as a client installed on some device. Being router means, you can have one thing (Android mobile phone, for example) running fqrotuer, then other devices can just connect the wireless network created by fqrouter.

From the linked page: "Wifi repeater is a unique feature, however it requires hardware/driver support", so the answer is, "It depends on your device." Also, that feature requires Android 4. –  Dan Hulme Aug 7 '13 at 19:25

Yes. The Alcatel One Touch Glory 2s has this function. You can choose to tether wifi via wifi or mobile data. You can create the SSID and password too. I used this phone as repeater to my home wifi router.

You should try Open Garden Wifi Tethering. It supports bluetooth, so You can easily share the connection this way. Of course, it would be slower, but still wireless. If You don't have bluetooth adapter, You can buy one on ebay for less than $2.

No. To do this would broadly speaking require multiple Wifi interfaces (or specialized software) which is not readily available (or easily installable) on Android.

In general this is done on Linux using something like hostapd in master mode: I don't believe that is easily setup on any Android phone.

Just found one solution that I can end up with: forum.xda-developers.com/showthread.php?t=1065652 but it assumes usb cable connecction between the lapton and the phone. –  Max Aug 19 '11 at 16:15
