My TP-Link AC1200 lasted about three years. Back in October 2020, I had frequent internet failures which I initially thought it's the line issue. After frequently called 100 and getting assistance from Unifi team, it's been confirmed that my AC1200 had finally stopped working. It showed connected but no internet. It's been a great pleasure & experience for me using the AC1200 which rarely gave me problems.
Now I try a new router from Asus. Just about time for me to upgrade to Wifi 6. I got a special price on Shopee 11.11 sale, RM462 for TUF AX3000, which I thought a very good price. I hope it'll last longer than AC1200.
