I happen to be a RT-AC56U owner too. Some of its 2.4GHz signal gets bounced off the ceiling, out the window and down to the ground (no line of sight) where an area of a marry-go-round ..within I get strong signal and can surf the web. The router is on 18th floor!
You have good suggestions from various people. Hard to tell which will perform well enough without trying. Perhaps time for you to action and let us know what works out best
True. Bought a Nanostation Loco m5 and going to configure it as a
wifi access spot tomorrow. Will post back (hopefully with info re how it worked, but beware: possibly more questions! Thanks for all of your patience). Still not entirely sure on whether the 5ghz or 2.4ghz, but I posted in various spots and since all of my devices (except my printer, but that's not a dealbreaker) are 5ghz compatible and I'm in a congested neighborhood, all but one said 5ghz best to try first.
BTW: Ubiquiti's customer service can REALLY suck! I've chatted with four and two of them were great, two were absolutely horrible. The guy today wouldn't give any suggestions, just responded to my questions regarding various products, and as I'm sure you know they have a ton. Just "yep, might work;" "nope, won't work;" no explanations. Not very helpful if you have to go through 20 devices that can be configured in a dozen+ different ways, and you know next to nothing about networking.
So after two hours I was like "look: just tell me what you think a good configuration would be given my constraints!" he was all sullen, and I asked for his supervisor, who answered my questions in fifteen minutes.
Plus they're all trained to stick to the party line that "you MUST have a total LOS, no obstructions." I've read almost everywhere that while it isn't optimal not to have a CLOS, it still works better than range extenders, etc. I know they need to CYA, but I'm buying it from a 3rd party (Amazon) and said I'm assuming the risk and won't hold it against them if it doesn't work. The good techs (including the supervisor) were able to respond appropriately, not just parroting "LOS... LOS... LOS" like zombies.
Maybe they're good for ppl who know what they're doing, but if they're expanding into the consumer market, they gotta up their game.
Will repost! Thanks to you and everyone who had patience with this noob; learned a lot!
