I recently bought the newest Airport Extreme to replace an older one. I have Comcast Internet with a modem from about a year ago. The last few months Ive experienced issues with the router and/or the modem, primarily my ability to maintain an internet connect. Id say things work great about 80% of the time, but the other 20% Ill have internet intermittently every few minutes and then itll cut out. Im up to date on my Airport Extreme firmware. Im not using any security aside from network access being restricted to MAC addresses for my devices that I enter manually. Basically, at random times Ill be connected to my router but will then not have internet access. Sometimes I get the yield sign on the Extreme in Airport utility, other times the Extreme will be green but the Internet connection will be orange. Ill restart the Extreme and/or the modem, and things will work for a minute and then Ill again lose the internet connection. Eventually things will go back to normal and work fine for hours or days, until the problem occurs randomly again at some other time. This had been happening on my 5 year old Extreme, and so I thought buying a brand new, current Extreme would solve the issue. It seems it hasnt. Im starting to think it must be the modem. Does this issue sound similar to anything anyone else has experienced? I would rule out the Extreme entirely, except sometimes I get that yield symbol on the Extreme and it makes me think that its a network issue and not a modem/Internet connection issue. This issue affects my 2012 Air, my PC, my iPhone, my girlfriends PC so its not a device issue.
