What brand/model of equipment? Besides the companies website reviews, I can’t find any real users. Hate to put all the money out for epic failure.
that's the state I was in a couple years ago. I'm cheap so I started with some lower power access points that were a waste of $ for my situation.
I'm using wavlink dual antenna 2.4 ghz access points. The antennas are removable, so I get yagi style antennas on ebay.
I've not tried 5ghz because higher frequencies have an inherantly shorter range. So I'm only attempting 2.4ghz.
I saw a review where someone was using them for internet access at an RV park, and complained they only last 2 years. The reviewer was suspecting the rubber seals on the antenna connection ports fail, letting water inside the unit. I don't know if that's correct or not, but the yagi antennas I get have about a 3 foot cord on them. So I can put the access point inside my building with the antenna mounted outside. I'm approaching the 2 year mark, so I can't tell you yet if mounting them inside is helpful or not. But after reading that review, getting the unit itself inside and the antenna outside seemed like a very good thing to do.
Some reviewers compain about wavlink customer support. I'm satisfied with it. On any cheap overseas electronics, if they'll respond within 24 hours and eventually get me a resolution, I consider that good enough. Twice I've contacted their customer support. Once was because I tried using another vendor's POE power supply and fried the wavlink. After answering their questions, they sent me a new unit for free. The other time I contacted their customer support was because I couldn't get it working in a specific mode. In my blind I wanted the wavlink to connect to the garage's wifi AND extend the network under another ssid, with no router/nat/dhcp running on the wavlink at the blind. I suspect that's the least common mode for people to configure it in, but the manual said it would do it, so I tried. It wouldn't work following the instructions in the manual. They sent me a special build of the firmware and it worked.
So my experience with wavlink has been favorable. I'm a little surprised to see so many bad reviews on them. Maybe its because people buy this type of equipment to solve hard networking problems, and nothing on the market will make those hard problems trivial.
