as the title goes. what’s real wifi transfer speed of that router, hap ac? let’s assume ideal conditions (no background noise, client in close proximity, updated fw, ac-only setting, Ceee wide channel…) and one ideal ac 3x3 client, which is not another mt device (meaning no cheating by means of nstreme or nv2).
and what’s possible to get out of say 2x2 ac client, if someone knows.
i’m getting 260mbit between my killer 1535 wifi card and hap ac, cpu load on mt is about 30%, tx ccq about 50%. i think that’s too little but i don’t know really.
yes… any tips to improve it? on low speeds it’s 100% (surprise, surprise) and my client connects with 866mbps, so i have chances at least in theory. it’s my first mt device and i really like it, but to be honest, learning curve is a bitc* and documentation is really scattered.
mt at one end of the hall, attached on the brick wall at 2.2m height, which is 20cm under ceiling, upside down (wired interfaces facing up).
client was positioned in my hand from 1 to 8m away with no change in ccq, apart from when i was walking away or towards the router. signal should be about -50, -60db, correct?
i saw a post or a mum saying i could measure signal on each antenna to see if there is a large difference. is that possible within ros?
quoting myself here, but i just found the answer, it’s in the wireless->registration->client i want to check. so, signal per chain strength is -50, -53, -50
edit:
i’m new also to the real world. before my mt i did only internet research and i underestimated the meaning of “perfect conditions” . so, i re-did measurements. distance between mt and client was ideal according to another topic on this forum - signal strength ~ -50db, floor noise -100db.
results: spikes of 400mbps down, 500mbps up, average not much under it. (hehe i actually had to pick bigger file to transfer). not sure why uplink is faster, but that’s life.
now the big question: i don’t like standing in the middle of my hall, 3.4m away from mikrotik, to get good wifi. is there anything i can do to improve reception out of ideal conditions? i read increasing tx power sometimes works, but mostly only over-stresses the transciever chip… i also don’t want to move mt under my couch.
When using 5GHz band (and higher), LOS gets quite important. Brick wall penetration is almost zero, so is refraction on corners. So … it is important to have AP placed at strategic place, ideally close to point where clients mostly use it. Sometimes this means pulling ethernet cable through a wall or two.
To improve WAF (wife acceptance factor) I put AP inside some closet. Plywood absorption of WiFi signal is bearable.
yes i saw… moving client for 20cm so that it hides behind a corner of a brick wall halves the transfer speed instantly.
my urge to have 500mbps which i almost never use is not strong enough to drill holes
@eddieb, the 500mbps link you mentioned you achieved - what was the environment? I guess LOS, snr > 50db, -55db on all 3 chains, about 3-8m away from router?
When you have an urge to use WiFi around a corner it’s better to use 2.4GHz band (if you don’t use it already). That highly depends on interference from neighbours’ APs of course.
My RB951G, hidden inside a closet, behind a brick wall (or around two corners if that signal actually travels through the door), up the stairs … and still at -75dBm, enough to do some web browsing, youtube movie watching, etc. 5GHz is long gone by there (did a test with RBD52G, which is dual-band. 2.4GHz was similar to just described).
Real world result from a phone in a room across from the hAP AC (wall mounted high up). Almost clear LOS (has to go through a doorway). -57 dBm on the hAP AC, -54 dBm on the phone. Upload limited by ISP.
no. as it has been discovered, CPU gets capped at 500mbps and that’s the end of it. that speed is reachable even with using 2-chain client, such as on my dell xps.
now i only need to figure out why i can only reach that upload, while download stays below 400mbps. could it be my 2 little receiving chains?
We did reach nearly 700Mbit, but that was inside an anechoic chamber with no outside interference, and with specific iperf3 settings. With normal conditions you should expect 500-600Mbit on 3 chains.
mind sharing your settings? I’ll see if I can lower my CPU consumption. I did my tests by copying large file between NAT on wired IF and my wifi client.
ps. i’ve seen somewhere a “best 2018” test and the winner really was something, AC3xxx-something, 8-legged, 300€+ beast. First router to hit a 600mbps mark. Normis, don’t let them know.
. so, i re-did measurements. distance between mt and client was ideal according to another topic on this forum - signal strength ~ -50db, floor noise -100db.
