using old router(Tenda N300) for increasing range of wifi without wire(wireless)

Hello guys today's video is about using your old wifi for increasing the range of new or current wifi . this video is more usefull for those whose phone and other devices have less strength to capture the signal of another wifi which is abot 10 m far away from their home .so they use their old wifi to capture the signal from far wifi and transmit to other devices which cannot do so.
