Finding clients that will take full advantage of 802.11ac speeds is very hard to find. Most are 2x2 that can never hit highest speeds. I see there will be a AC88AX, which at least would have more function than the routers running 802.11ad.
For weeks been looking for new router as my old one is just 1x1 802.11n dual band, 300 max speed and about 8 or 9 years old. Looked at some Netgear, Linksys and Asus routers and will probably buy the RT-AC88U. The GT-AC5300 seems to have problems, issues I am hoping to avoid in the 88U.
Something I did like in the Netgear router was the Nighthawk X10, R9000. It has the triple band, but one band is the 802.11ad which is and will be useless. However, the router ran Plex Server with upgraded CPU and memory.
If and when Asus comes out with the 802.11ax or some other new router, it would be nice to see Plex Server, if marketable and stable. In the least, the consumer would have something to use while waiting for client wifi to reach higher bandwidths in 4x4 or in the least as close as marketable. Netgear seem to sell a lot of the X10s, given that the 802.11ad band is useless.
I guess I'll have to wait until 2019 to see specs on the AC88AX.
