My 6-7 year old Netgear R6300 v2 started having issues with the 5 GHz band. Constantly dropping connections. 2.4 GHz still very solid.
Google Nest WiFi is a mesh wifi. Updated version of older Google Wifi
Black Friday deal on router & point covers up to 3,800 sq ft. Normal price almost $300 incl. Tax. BF Deal? I got mine for $150 incl. Tax & shipped.
Not much to it....(2) devices with AC plugs & a short ethernet cable. Point has a mic on it for using "Hey Google" more on that in a bit. Router has only 1 LAN port so no Link Aggregation (which you'll need if you have Gig connection)
Use Google Home to setup. Scan QR code on device - Found device fairly easy using my Android phone (no iPhone to test but I'm sure it will be fine.)
Had to reboot cable modem, connected to internet -- name your network, set a password & boom all is well. Fairly easy setup surprisingly.
The router handles 5 GHz traffic & 2.4 GHz traffic all by itself using the same SSID. I have devices that only work on 2.4 GHz (PS 4, Harmony Hub for universal remote & 4 Sonos One speakers & wireless 🖨️)
Performed a speed test.
I have Xfinity Extreme+ service 600 MB Down -- just 1 step below Gig.....and that speed test was on my new Pixel 5 phone. Jaw dropping for a phone.
Setup point -- ultra easy all wirelessly.
Last is voice imprint -- say 4 different phrases & now it knows your voice for personalized commands. Also a hardware switch on point to shut off mic for privacy if you like.
You can also setup apps & TV or other devices to launch using your voice. I personally skipped most & you can setup later if you like. I did setup SiriusXM so I can tell Google to play Wayne & Larry on game day. 
LMK if you have any questions.
