I have done my own research and was leaning toward the TP-Link AC2300 but also have heard good things on some ASUS, Netgear and Linksys. What model WIFI router for a large home that needs range for under $150? I have researched this in depth online but want to hear from the experts on here if you don't mind. Thanks!
W/r/t a wifi source on each floor without Ethernet cabling, and having a single router cover your whole house,
this describes a workaround that was tested on a TP-Link C3150 which is pretty similar to the AC2300. As far as the R8000 goes, one downside to triband routers is that you generally don't know which radio chain is sending out which 5 Ghz frequency, and the lower 5 GHz band has
much weaker transmit power than the upper band. Also, the R8000's FCC test report shows the little antennas have puny gain (1.47 to 1.76 dBi on 2.4 GHz and 2.08 to 2.2 dBi at the upper end of 5 GHz).
The DIR-880L is probably the lowest cost 802.11b/g/n/ac wifi router with close to 1,000 mW of transmit power, if you want to shave around $90 off your cost.
For TP-Link, the C2600 is comparable to the C3150, having 32 MB of flash storage and 512 MB of RAM, and the C3150 has 128 MB of flash stroage and 256 MB of RAM, both having a 1.4 GHz CPU (but one being Qualcomm and the other being Broadcom). SmallNetBuilder hasn't reviewed the C3150 or C2300 AFAIK but did
review the C2600 and found it to hit up to 583 Mbps at 5 GHz, and anything close to 600 Mbps is the best in real world throughput you can hope for over-the-air with 802.11ac. (802.11ax will be better, but you'll need to wait for that.)
