6 devices in the house, only 4 ports on the router
I have 2 PC's, a bluray/Netflix box, a 360, a PS3, and a Roku box. My router only has 4 ethernet out ports. The Roku and PS3 will work with wireless, which is how I'm getting by now, but I prefer everything to be wired.
The Roku has been acting up when on wireless, saying there's a "network problem", but it only happens when using Netflix on it. The other services work fine. When I plug a wire in, the Netflix problem goes away.
I have an old 4 port ethernet hub. Can I take one wire from the router into the hub then split that to 2 devices? (each which need a unique network address, I'm assuming). If not, how can get more wired connections? Is the only way to buy a new router with more ports?
