I bought PlayStation 3 some time ago. It was the reason why I started to set up a proper wireless networking stuff in my home. Since we have 2 floors, and the router is located in the lower floor and the PS3 in the upper floor, there’s some issues to ensure the signal is good.
First, I bought a better antenna to replace the basic router antenna. This was a pretty cheap upgrade (30 eur) and made the signal somewhat better, but I wanted more. I bought a wireless airstation which I connected to the adsl modem. This made the signal bit better again, but I was still not happy.
I knew that the store would have one more upgrade available, but then I got a better idea.
I went and bought 20 meter RJ-45 cable, some “make the cord stay nicely on the walls” nails and a hammer.
100 hammer hits later I got a cord coming from downstairs to upstairs. I threw away the airstation and just decided to use PS3 with a cord.
Cave man era style, but works bloody well.
