can DNS errors be a hardware fault

My airport extreme base station keeeps dropping off line due to lost DNS Servers. everytime I make a new call for resolution by changing a web site, the Airport goes offline and has to be redone .. I plugged my laptop directly into the Comcast router and there isn't an apparent problem. The Airport Extreme is tunning the current version of the firmware and my Airport utiility is current on the iMac and MacBook. When I hook everything into a verison wireless hotspot (bypassing the Airport) all connnecitons are fine..

So, is this a Software problem or a Hardware problem?

Thanks for any insight.

If you change the DNS servers on the Extreme to 8.8.8.8 and 8.8.4.4 what happens?

I set the DNS to 8.8.8.8 and 8.8.4.4 and therer is an initial resolustion, but then it goes south and the airport Utilityy says "disconected" from the Internet.

the basestation alternatively says stuff like No DNS servers, Double NAT..

The status light on the Extreme is Green but the airpotty utility says "disconnected"

Put the Extreme in bridge mode and see if this solves the problem. As you already have a router the Extreme just needs to be an AP.

Well, it took a bit of investigation and some $$$$, the problem was an antique cable modem that was introduicing all kinds of porblems in the data stream. I teplace cable modem with a new one and all is (so fat) doing well. At least the5r is no timeout on tyhe Google home page. 🙂)
