200 square meters is absolutely massive for Taiwan lol
Well, for one, it's "out in the sticks" and they also count outdoors space here, so that includes a tiny "garden" as well as a small balcony, a small area for the washing machine, as well as some percentage of the general community areas. I'm guessing the house is about 40 square meters per floor or so. Ground floor and top floor is over 3m in ceiling height though, with the middle floor being about 2.4m. So a very tall building, but with only 2-3 rooms per floor. It makes it quite complicated to get good Wi-Fi coverage. At least now, I have Ethernet between the floors which makes it a lot better. The range extender at the top floor used to drop the connection to the second floor all the time, despite one being right above the other...
I feel for the neighbours behind us, as they have four story homes...
I have a similar situation with my town home, my office is directly underneath my router (on the main floor) and gets excellent throughput but my master bedroom needs an AP as the signal barely penetrated it (regardless of main router) even though it was one floor up and about 30ft away through wood & sheet rock.
I currently have my old Netgear Nighthawk 6700v3 set up in the new house as I'm doing renovations (painting, new wood floor, etc.,) and the 5ghz is solid but fails to reach the furthest bedroom on a regular basis while the 2.4ghz throughput is 1/4 of my max ISP Mbps once you are more than one room away from the router. Once we are ready to move in I will bring over my current main Asus router that offers betetr 2.4ghz throughput but similar 5ghz performance as the netgear.
I've checked it out and posted on their forum now and then (as have you). I'm just glad Tim is back running the site, for a while it looked like it may join jonnyguru.com
Being on one level clearly helps, but it comes down to what's inside your walls as you know. Pipes/wiring in the wrong place can mess up the Wi-Fi signal quite easily.
I've seen people that are mounting a high-power AP in the loft to cover their home, as the idea is that there are less things in the ceiling in most homes, as normally you only have insulation and some electrical wiring for ceiling lights there, so fewer things that can interfere with the signal, plus, it's out of sight.
I presume you're using Merlin's firmware then?
Yeah, Tim is good at what he does, but maybe not quite adventurous when it comes to tearing down the hardware sometimes. We bought the same Octoboxes he had when I was working at Securifi, very nice pieces of kit, but not cheap. Was impossible to do proper testing in the office without them, as there was always a bunch of RF interference going on, for obvious reasons. Tim never really left, he was working full-time for Octobox, but I guess they decided to let him run the site on their dime, which I think in some ways serves them quite well too. They have a somewhat limited customer base and what Tim does is the best way possible to promote their products. Just need to get him to write up the reviews of all the new toys he's tested already.
