Linksys Hydra Pro 6 Mesh WiFi 6 Router

I purchased the Linksys LN3121-AMZ WiFi 6 Mesh Router, as a replacement for an older Linksys router. The older router still worked good, but it is WiFi 5 and 3 years old, so I thought it was time to replace it. I installed the new Linksys LN3121-AMZ router as soon as I got it, and was ready to set it up. But when I plugged in the power cord, it wouldn’t come on. I tried the power switch on the back thinking maybe it was in the off position, but that didn’t work either. I even disconnected everything and tried plugging it into a different socket, but it still didn’t come on. At that point I knew there was something wrong with the router itself, so I got on Amazon, and set up a return. I decided to go with a replacement, and give it another chance. Amazon sent the replacement out right away, at no charge. And as soon as I got it I plugged it in first, to make sure it came on. It did so I installed it, then used the Linksys app on my iPhone to set it up. It worked fine at first, but then it started loosing the internet connection. I also had problems with some websites loading, and one of them was my own site. So I used the web interface, and proceeded to go through each and every setup page, comparing them to the screenshots I have, of my old router settings. I eventually came across a couple that were different, so I changed them to match the old router. And as soon as I did, all the website stated loading again. The setting I think was causing the problems, was the MTU size setting, under the Connectivity > Internet Settings tab. But whatever the cause I got it, and it’s been working fine ever since, without any issues at all. Even though I had a problem with the first one I received, (which can happen with anything you buy) this is really a good router. It's much faster than my previous router, and the WiFi coverage is incredible. It hasn't lost a connection once since I made the setting changes, and I'm glad I gave it another chance.
