Multiple laptops can't see wireless router

Hello,

I have a Windows 7 tablet and Macbook that have been connected wirelessly to a Netgear Wireless Cable Modem Gateway (CG814GCMR) for several months now with no issues. All of a sudden, they now cannot connect. My network does not show up as an option on either device. I can see all my neighbors network but not ours. The modem is working fine as I have a Dell laptop connected via wired connection as well as one Vonage phone line. It's just the wireless devices - iPhones and iPad also don't connect - that won't connect. Any help would be appreciated? Thank you.

Good point, it always makes sense to unplug the netgear gateway for a couple minutes then retry connecting, before doing something drastic like using the reset button which will set everything to manufacturers defaults and cause you to lose your settings. I just assumed that was already part of your initial troubleshooting.

I apologize for the omission of what I tried. I did try rebooting the router and laptops to no avail. Our cable guy setup the router when I wasn't here. He wrote down the ip address of the router but I haven't been able to find it. Thus, I had to reset it to factory settings this morning but that still did not resolve the problem. Neither laptop can see the network. My next step will be to call my cable that supplied the router to replace it or fix it. I will post the results after contacting my cable company.

One other question: Through the wired laptop, I displayed the Network Connection Details - Windows XP - to the Physical Address which I assumed would match the MAC address on the router. It does not match. Is this a wrong assumption? Thank you for your assistance.
when you run the ipconfig/all command it should show you what the default gateway is. This is the ip address of your netgear gateway. You type in this ip address into a internet explorer window and the firmware for your router should popup on the screen. This is where you can make changes.

On a computer that is hard wired to the netgear gateway... obtain the ip adress of the router by doing the following:
Click your start button click on run.... then type in cmd... press enter. Then you should get a dos screen type in ipconfig/all then press enter... it should list what the ip address of your computer is as well as the subnet mask, and the default gateway....

Using the computer that is hardwired to the computer open up an Internet Explorer (IE) window. In the IE window instead of typing a web page address, type in the ip adress you found when you ran the ipconfig/all command. A screen should popup showing the firmware of your router. Or you may have a login window, if a user and password has been setup.

Your internet service provider (ISP) should be able to walk you through changing the setting to your netgear gateway appliance. They can even test the router to see if it is working from their end. They may even be able to log into your system to make the proper changes.

sounds like the router may be the problem, I would replace it. It sounds like there is intermittent problems which is the reason it is losing the default settings, preventing you from connecting wirelessly. I would replace the netgear device. It could have been a power surge that is causing it to run intermittently, and preventing you from conncting wirelessly. The netgear gateway should not reset itself unless there is something wrong with it.
