Playing ps3 online using wifi from laptop
i have wifi signal that is great on my laptop 100% but when i scan my ps3 for the same network it say 20% or lower so when i try to connect it logged me rite off is there a way to play online without a modem and router
If the distance between the wireless router and the PS3 is greater than your laptop than the problem exists with your PS3's placement itself. Try moving it to a closer distance. If not:
You can plug your PS3 directly into the router using a ethernet cable but that all depends on how far the distance is as well as if you're willing to to have a long wire running to both devices.
If you're willing to spend a little more cash, you can purchase a WiFi booster to get a better signal strength or if you have a cheap-o router you can trash it for a decent quality router.
