EX6200 Extender keeps kicking computers off with 'IP configuation' errors

My Equpment:

  • Modem: Franklin Wireless R850 4g LTE Mifi Device with Sprint service (no ethernet or USB ports)
  • Extender: Netgear EX6200 (firmware version V1.0.3.74_1.1.109)
  • Connected Devices: 1 desktop, 1 home theater PC, 2 laptops, , 1 home server, 1 blu-ray drive, 1 printer, 1 receiver

My Desired Setup:

The only thing fed directly from the modem (via Wifi) should be the extender.  The extender serves everything else in the house.  Most items can connect via wifi with the exception of the desktop and the server.  These are connected to the extender via ethernet (the home theater pc, blu-ray, printer, receiver, and one of the laptops is actually connected via ethernet as well to make faster in-house connections).

 

The Issue:

This is likely stemming from my complete ignorance when it comes to networking, but the wifi and the ethernet-connected devices are randomly getting kicked of the internet with "IP configuration" errors.  I have reset the modem (quite a few times) and the extender (also quite a few times).  Often this fixes the issue, but this happens at least five times each day - an annoyance I am not willing to deal with.  I have done a factory reset, been on the phone with tech support, etc.  I am currently just back to using the modem without the extender and have not had any issues.

 

I tried everything for about three weeks with the factory defaults on the modem and the extender (except for username and passwords).  The issue persisted.  I then tried giving the extender a static IP address.  I thought this fixed it, but the issue popped its ugly head up after six hours.  I have turned off DHCP on the modem... no luck (it's now back on).  I'm stumped... anyone?

 

Thanks ahead of time,

Roy

    It sounds like you have devices getting assigned conflicting IP addresses.

     

    You are going to need to give more details of how things are configured.  Did you have both the router and extender set up as DHCP servers?  If so, I hope you made sure their ranges were in the same subnet but did not overlap.  When you gave the extender a fixed address, was it within the extender or by reserving an address in the router?  If you do it in the extender, you have to make sure the router doesn't also assign that address to another device, so reserving an address in the router is the better way to go.  Are both using the same network name(s)?  I have a different Netgear extender, and ran into problems until I gave the extender and main router different network names.  Bonus is I now know to which any device is connected.

     

    You say only the extender is connecting to the router.  How do you control that?  If your router has provisions for MAC whitelisting, try enabling that and only whitelist the extender.
