RouterOS 7.22
Hi there,
Some time ago, there arose a need to upgrade the wireless bridge built on UBNT NS 5 AC Loco to something more modern that could handle more than 400 Mbps over a distance of 110 meters. That’s when I came up with the idea to buy two MikroTik wAP AX units. On the transmitting side, I also planned to use the second radio to cover the area in front of the warehouse, which should at least partially solve the problem of poor mobile network coverage through Wi‑Fi Calling.
So basically, I wanted to achieve two functions with a single device, and it seemed that the wAP AX would be perfect for that. I bought the units, did some initial configuration, and started testing indoors first (the antennas have line of sight, about 5–6 meters apart). That’s when the first disappointment came. Although the devices report a 2.1 Gbps link rate, the actual speeds are... far from impressive. The best I could get was around 500 Mbps on iperf3, and in practice (for example, when copying files in Windows) it’s only around 350 Mbps real throughput.
I started digging into the configuration — even enabled Superchannel mode to try other frequencies — but the results were exactly the same. Then I thought maybe 160 MHz wasn’t stable, so I switched to 80 MHz, but the speeds remained unchanged. I even connected my laptop (which supports regular Wi‑Fi 6, 80 MHz bandwidth), and again, speeds were only in the 300–350 Mbps range.
I’m quite sure I messed something up in the configuration somewhere, because I’ve seen several videos showing people easily achieving 700–800 Mbps on this hardware.
Here’s the AP configuration below.
