Airport Extreme dropping connection

Issue with client's Airport Extreme (one month old) needing to be rebooted 4-5 times daily. Clients lose internet connectivity - both wired and wireless - green light on router. Static IP assigned to router and manually entered. Installed in small office - less than 10 users - all Macintosh. Port forwarding on three ports for Daylite CRM. Firmware at 7.5.1, No guest network enabled.
Troubleshooting included:
Switched ISP from ADSL to Cable (completely different technology and modems)
Switched router out and replaced with identical router - reconfigured manually
Turned on interference robustness
Changed both wireless channels
Changed out power supply and put both modem and router on UPS

Here's how to do the reset, though I doubt this will help your wi-fi drop.

RESET NVRAM

Verify the sound is turned on and set to mid volume or higher.
Shut down the Mac. click  > Shut Down... Be sure the Mac has been shut down properly with no errors.
Locate the following four keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these
four keys down simultaneously in step 5.
Turn on the Mac.
Press and hold the Command(⌘)-Option-P-R keys immediately after you hear the startup sound.
Hold these keys until the computer restarts and you hear the startup sound for a second time.
Release the keys.
***NOTE*** After resetting NVRAM, verify Find My Mac configuration

information about SMC Controller: http://support.apple.com/en-us/HT201295RESET SMC Laptops with a battery you should NOT remove on your own (MacBook Air, MacBook/Pro)

Shut down the Mac. Be sure the Mac has been shut down properly with no errors.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the Power button at the same time.
Release all keys and the power button at the same time.
Press the power button to turn on the Mac.

RESET SMC Older Laptops with removable battery & all Desktops

(Intel based MacBook/Pro or iMac, mini, Mac Pro, or Xserve)

1. Shut down the Mac. Be sure the Mac has been shut down properly with no errors. 2. Disconnect the MagSafe/power cord from the Mac, if it's connected.
3. Remove the battery. (older laptops only)
4. Wait 15 seconds. Press and hold the power button for 5 seconds.

5. Release the power button.
6. Reconnect the battery (older laptops only) and MagSafe/power cord/adapter. 7. Wait 5 seconds, then press the power button to turn on the Mac.

That seemed to help me too! Apple Extreme and Cox Cisco DPQ3212

Thanks for the note. I followed what you suggested of changing the mode from routing to bridging and the problem went away instantly.

Mar 24, 2016 6:38 PM in response to AAPLc

I have had issues for a while with Cox here in Las Vegas. I just did what YNP Photog did and I hope it works. I will update in a few days.

I wanted to update with my experience to help anyone who might stumble in here with the same issue, like I did.

COX Cable Modem, Docsis 3.0, Airport Extreme (Tower), El Capitan

I was losing internet connectivity randomly for the past three days. Not WiFi, just internet. I ripped my system apart, never could figure it out. Finally saw some posts in here about IPV6, and sure enough, disabling it in the Airport Extreme appears to have immediately resolved the issue.

For further proof, I submit this little gem taken off the Cox website (http://www.cox.com/residential/support/internet/article.cox?articleId=0bced860-9 666-11df-6baf-000000000000:

Whatever you do, Cox, DO NOT send out a communication when you flip the switch. And DO NOT inform your chat techs. They suggested I look at my cables. LOL. Captive audience, I suppose. I have no alternatives. Good luck!

May 6, 2016 6:48 PM in response to pyromichael

Thanks! I have been struggling with this problem for few months. Talked with Cox level 2 support several times and they are not be able to help.

Now everything seems fine except that no IPv6.

Anyone have an update for this problem yet? I still have IPV6 disabled but eventually Cox will run out of IPV4 space and then it will be a problem again. Cox Phoenix, Airport Extreme Router, Motorola Modem, Windows 7.

IDentical problem with a newer model, and pulling the plug is a pain in the butt. About to change to another make. We shall see.

I had this problem recently also. when I talked to my ISP (MediaCom), they told me that the signal coming in to my modem was very weak. They improved the signal and that seems to have solved the problem.
