" I correct via router to my hosts computer." I am guessing you are connecting to the Internet via the wireless router not your hosts computer.
If I interpret correctly the wireless router is 20-25 meters away. Not an impossible distance to hardwire but you are the only one who can decide if practical.
As stated, reseting the router by unplugging is sometimes the only fix. If you can see the lights, there are normally 4 that are on or blinking if all is well.
Click the wireless icon in the bottom right of computer to check connection and strength.:jap:
