I am trying to make a wifi repeater. My router's signals don't come to my study and instead of buying a proper wifi repeater I prefer making one.

I want to learn how to make a simple wifi repeater that:

  • repeats/boosts my existing home wifi network by connecting to it.
  • Has some kind of a GUI or something that allows me to connect to it first (from some smartphone or PC) to configure it to my home network. It should find and show wifi networks around and then connect to the one I want it to upon my command.

I am new to electronics. Arduino is my preferred platform. If there are other easy to do alternatives that shall work too.

Any kind of help will be appreciated...tutorials, blogs, etc.

"Arduino is my preferred platform." Not for a wifi repeater it isn't. – Ignacio Vazquez-Abrams Mar 9 '15 at 6:11

Get a router that support OpenWRT. That way you can still "hack" the unit. – Gerben Mar 9 '15 at 11:25

An arduino wifi repeater would in theory be very slow. Since you need to record the bit stream to the internal memory, then switch the spi to the transmitter, and send the bit stream, im unsure about what would happen if you miss a few bits in the process.

Arduino Wifi Shield - the price of a wifi shield 85 usd

Wifi repeater ebay the price of a wifi repeater 22 usd.

This makes me question why one would go through the troubble of making a wifi repeater of an arduino.

Even investing in a raspberry pi and a wifi dongle would be less expensive.

Indeed - lots of people have bought cheap wifi access points to hack as wifi interfaces for their arduinos, because at points in recent history you have been able to get an entire wifi router for less than the cost of a wifi shield. – Chris Stratton Mar 9 '15 at 14:19

the network parts are "owned"by the yun side of the board. the yun acts like a mini linux pc, who can seperatly connect trough a bridge library to the arduino. so.. i think you could do it or make it a router that would probaply be easier, but this all wouldnt depend on arduino code, more depend on if there are WRT packages who can do this.. i thinks they should exist as this linux variant is in other routers too.

(better route then repeat btw, repeats puts delays on your entire lan)
