I had no problems updating all three to new firmware, linking them to the cloud, and getting online. I did put my old SSID and password.
One thing to note that nobody mentions, is it does come with an app that has certain features but if you want more of the home shield protection you do have to pay $54 a year. But it gives you real-time IOT protection, malware protection, and DDOS protection. I got it because the price isn’t that bad for a year. I think it’s worth it because I’ve had problems with malware in the past.
Also of note we’re finally getting our 300MBps download speeds that we had paid for years and never got with my old router.
I’ve had it for only a day so I really can’t say on the quality, but I’ve had TP link router’s before and I’ve been very happy with them, so I don’t see why this one should be any problems. I love the fact that it’s brand new with the newest protocols and the malware protection is definitely a plus. I’m happy!
I will update as I always do, if I find any problems along the line.
