Can't connect to internet thro wifi

After adding that second or third computer to your home network are you constantly fighting over who's using the internet connection? When your high schooler logs into his facebook chat, are you getting dropped off of your internet connection?
Or have you added a wifi router and is your whole network not staying connected like it did before you added your wifi?
These are common issues and we answer these questions often at FixYa.
Here is s a tip that will get you past the internet connection being dropped by someone else on your network attempting to log into the internet or help you get that wifi up and working with out all the cut outs and drop offs.

Follow this simple procedure and you'll be amazed!
1. Turn off everything. Turn off computers, routers, modem, printers... everything that's on your LAN (local area network) or home ethernet.
2. Turn on your wireless router next. With the ethernet cable connected to your wifi router to your modem and let it cycle up to running. If you aren't running wifi, do this with your main router. Make sure your modem and everything else is still off.
3. Turn on your modem (enet cable attached to wifi router or main router) and let the modem cycle up to running.

What you've done is allowed your wifi router to be established as the "MAC" Address for your modem. Modems look for a single MAC address. Once the router has this address, the router will maintain the connection with the modem and the internet, AND will assign MAC addresses to your computers, network printers, network routers etc, while still maintaining your connection to the internet.

4. Turn on all other peripherals, computers and network printers. At this point the order of power up isn't important, because your router will be assigning separate addresses to all the computers, etc on your network.

That's it! The secret's out! Just keep this handy... remember if you have power outage, you'll need to reboot in this order again... Happy Home Networking
