Ancient = 2011 for V4 based on V1 from  2009, perhaps even older.

In this case, it does not look like a problem on these legacy APs 8-)

However, I doubt there is much security available currently (WPA/WPA2 mixed mode), and not much performance on these N600 WNDR3700v4 WiFi.

Re: microchip8  and michaelkenward

What am I missing now or what will I gain by purchasing newer routers?
The Charter cable modem is free (no more monthly “rent”), so I don’t need a router with a built-in modem. All three WNDRs use WPA2-PSK [AES] with a good password to keep the neighbors out. I get a solid 95-100Mbps on all three routers, the expected download rate from Charter. If there’s a good reason, I’ll be glad to upgrade. I’ve had the v3 since 2012 and just got the two v4 for a good price on eBay.

The access points will drop the Internet randomly while I am working. I can see the exclamation mark appear on the WiFi symbol at the top of the phones or tablets telling me it has dropped. I’m sitting within 10 feet of the access point.

I should add that our 1950s house has expanded steel-mesh and plaster walls, so each room is effectively a Faraday cage, which is why I need the access points. From the primary router in my office I have a CAT-5 drop to two other rooms where the access points are located. From each of the three rooms I cannot see the SSID in the other two due to the shielding.

The primary router 192.168.1.1 (subnet mask 255.255.255.0) is the DHCP server for 192.168.1.2 - 192.168.1.199 for all the clients. I parked the two access points at 192.168.1.210 and .215, fixed IPs, so I can find them for configuring.

All three routers have the latest firmware from Netgear (v3 = V1.0.0.42_1.0.33, v4 = V1.0.2.102)

The Android phones, iPhones, PCs, printers, ROKU, home theater receiver, etc. are all served IPs from the primary router and usually keep the same address for weeks/months or longer due to the lease renewals. Their addresses are typically between 192.168.1.2 and .50, whatever they happen to be served.

Charter only gives me one IP for the WAN side of the primary router. The two access points are not visible outside my LAN, nor should they be.

Security: All three routers are set for WPA2-PSK [AES] with a good password. WPS is disabled as I don’t need it. The guest SSID, Remote management, UPnP, IPv6, are all disabled. I use Quad9 and Charter for DNS.

I’ll keep an eye on it and re-check all the configurations. Thanks for your time and attention.
