If anybody could give me a hand with this problem, it would be greatly appreciated! My setup is as follows: Cable internet coming into house and connecting to cable modem, cable modem hooking up to Ooma (VOIP for telephone service) device, Ooma device hooking into Airport (newer "N" Router) WAN port. I have an iMac hooked up to one of the LAN ports on the Airport. I have a PC laptop and AppleTV wirelessly networked in. The Airport "connection sharing" button is setup to be in "Bridge" mode, which is what it asked to do, under the Airport Utility settings. My problem is that my wireless internet signal drops out, then reconnects every few minutes, and I'm not sure why. I have had this setup for about a month now, and all worked fine up until about a week ago. My hard-wired iMac seems to work fine, and I can even stream movies to my AppleTV fine, but the problem seems to be accessing the Internet through my wireless network. Everything is choppy. My cable modem reset itself about a week ago, and I had to call Comcast to get them to fix the problem, which they did in a few minutes. They also stated that my modem was never registered with them the proper way, so they did that also. When I called Ooma, to see if that was the problem, they told me it was an Internet problem. When I called Comcast, they told me it was a router problem. Can anybody help me out? Is it really a bad airport that is screwing things up? If you have questions, let me know. Thansk a lot in advance.
