SXTsq G5acD max real throughput?

RouterOS Wireless Networking
1

ptp link is like 200m. The max throughput I’m able to get is 160mb of 400mb bandwidth available. Has anyone achieved higher?
link status
Strength -53/-53 dBm
ccq 93/88 %
signal to noise 55 dB
protocol nstreme

this is my configuration

switch wireless protocol to 802.11

3

in 802.11 i only get about 20mbs… what could be wrong?

4

i have sxt SA5AC connected to SXTsq 5AC creating a PTP connection with a distance of 300m, getting only 20mbps when using nstreme, then i switched to 802.11. To my surprise i get 300mbps RX, 400mbps TX. not sure why i don’t get the same rate both direction. I’m pretty happy with the 802.11 result. so i ditched the nstreme set up. nv2 even worse, kept getting drop-out.

5

I mean the real throughtput… not what the registration say.

Mine say 650mb both ways…

But a speed test wont go over 160mb in nstreme and 20-30 in 802.11. I have 400mb bandwidth.

6

How do you test the bandwidth? What equipment? What processor in the test equipment does the down / upload?

7

i test the bandwidth in www.speedtest.net. I test it in my pc AMD FX 6300 3.5ghz (six core cpu).

with Ethernet cable from router/modem connected to PC i get 340-380 mbs.

in my other house with the ptp bridge i get around 160mbs tops.

8

yes, this is the real throughput using bandwidth test, but I haven’t actually transfered big file thru this link yet. The real real speed may be not as show with btest. I’ll report back when I have result. In my case as stated before nstreme protocol even worse. My registration status from station bridge side says 866mbps which is max iirc.

9

My tests from yesterday (80MHz, room test, iperf3 tcp, 6.42rc30)

  1. nstreme - stable 180Mbps - it seems it’s max for nstreme regardless of device
  2. nv2 - unstable, max that I seen was about 300Mbps
  3. any - unstable too, max that I seen was about 550Mbps
    It looks that MT is on a good road, but still there is a lot of work.
10

Can anyone make an outdoor P2P test with 20Mhz channel? Thanks

11

what’s the distance between devices?

12

Less than 2m.

13

changing manual tx power to 13 to get a signal of -52-53 was the problem…

exact same configuration swithing tx power to default (-38-38 signal) give me max throughput… Now i get extactly the same speed from the ptp than if i do the speedtest by ethernet cable from modem.

how do i keep the speed, but fix the signal to a normal lvl?
