Really depends on your needs, if you feel your current house coverage and getting the speed you paid for.Wow everybody moved to AX already?
I am still using Asus AC2600, bought for $40 only.
Is this router good or bad? In terms of coverage?
If you are on a 500mbps plan, even on wireless speedtest on mobile you should be clocking near 500mbps (device near the router and has to be a recent mobile phone), if not then its time to get a new router as it bottleneck.
