@Dcortez - Nope, wireless is not part of Cox service unless; you buy their router, had them set up your router (CTS), or "other". I use other because some areas have some crazy stuff that I probably don't know about. Wireless strength is completely independent from internet service. To prove a point, look how much wireless strength you have, then unplug the modem, and the signal strength shouldn't change at all.You won't get online of course, but your connection to the wireless device will stay constant. Now, with that said, I don't mind helping. I was just making it known that you won't get much of a official answer from Mods or anything. Also if you post in someone else thread, and then they mark it as answered, it becomes locked and we can't respond. :-) If you make a new thread I will copy/paste this there.
So first, your network is Modem > Wired router > Wireless Access Point?
1. Are just the router and modem in the closet? Or all 3? Or did I not interpret correctly?
2. Do you already have ethernet running to the difference rooms? Could you describe that? Is there a ethernet jack in the central most location?
3. You have different options; you could buy a wireless access point with stronger signal, you could buy a wireless router with stronger signal and combine the wired and wireless, you could by a wireless repeater, you could install another wireless access point somewhere you have a ethernet line running to, or you could buy a wireless adapter for the computer that is getting weak signal. Or you could do a mixture of those things. Kind of depends how much money you want to spend, how much effort, and how big of a house we are talking. Give me a little background and I will try to make a suggestion. Also, give me a ballpark on how much you want to spend? Like between X and Y dollars.
