Hello, I have a USB internet adapter but my PC is in my room PC upstairs can I put it in a USB extension cables (5 m) and throw it through my window so it will be closer to the wireless modem it gets stronger signal ???
...
Yes, you can do that.
You will want to make it weatherproof, though.
You can use a cola bottle, Glass or plastic, that will fit the parts you want to use.
Feed the dongle into the bottle, then use RTV, wax, or pine tar to seal the bottle around the cable.
Make sure it's shielded from direct sunlight, or it will overheat.
A piece of white paper taped across the outside will work.
It may overheat just being in a bottle, sealed up, from its own power.
If it quits in the day, and works at night, overheating is the problem.
Be sure to use a "Drip Loop" anywhere you go into a building; you loop the wire with a low spot, and then being it up to the window, so water won't run down it into your house.
I figured you deserved an answer to the question you asked.
