Intermittent, regular loss of internet connection

[Bob_Fox]

Installed a NETGEAR® AC750 WiFi DSL Modem Router, Model D6000 in July 2017.  I use Mac laptops and iPhones.  

It worked perfectly until January 2018 when the green internet light started blinking.  All other lights remained solid green. I spoke with my ISP, who said that they couldsee not problems with their provision.  Over a couple of hours, we tried a number of resets without success but a factory reset, using an opened paper clip in the reset hole, seemed to work.  

For a while.  

So I changed the filters.  

The current situation is that almost every day, between around 4.00 and 7.00pm, I lose the internet connection for between 20 minutes and an hour.  It reconnects spontaneously.  It does not appear to be temerature or weather effected on external cables.  

On my list of networks, this router is listed as Netgear16 and there is a second listed as Netgear16-5G.  Both are password protected.  

I am not aware of any Netgear updates.

Any thoughts please?

When you changed the filter did you also replace the cords? if not you may want to try that.

Thanks for the thought - I replaced the cords at the same time as the filters.  I wonder if a firmware update might help and have downloaded the latest (D6000-V1.0.0.68_1.0.1) to try.

Yes try the latest firmware you could even try a older firmware and see if anything changes as well.
