Re: Low throughput question

Thanks leonix, I hadn't understood the notation.

Re: Low throughput question

Hi Leo, Why do you say that more than HT40-7 is not possible? My understanding is that MCS-8 uses the same modulation scheme as MCS-0, but with two spatial streams. I tried playing with the MCS settings as you suggest. I'm not sure how to modify it as per your image: - the web interface won't let me...

Re: Low throughput question

I also looked at the "Rate/LastMeasured" part of the registration tab -- it only lists up to HT40-7. Is it always like this? Am I never getting MCS8+?

Re: Low throughput question

Thanks JanezFord. My Tx/Rx signal strength for the laptop (as per the registration page) is -66dBm. I tried turning down the tx power (by setting the antenna gain to 13dBi [when I actually have stubby omni antennas (5dBi?)]), no change. Also I'm using the correct encryption. I double-checked the CCQ...

Re: Low throughput question

leonix,

Do you think that reducing MCS rates will increase throughput over my 5m link?
(Also: my CCQ is near 100%).

I'm running v6.10.

Re: Low throughput question

leonix: I'm not using nv2, just straight 802.11n -- so I don't think any of the TDMA stuff applies to my situation. n21roadie: my access-point and laptop are separated by maybe 5m with line of site -- so I don't think there are any fresnel zone issues (and if there were, they would apply equally to ...

Re: Low throughput question

(I should also mention that the problem isn't CPU-limited, CPUs are all lightly-loaded)

Re: Low throughput question

I did some more digging on this. Quick summary: - by setting distance to 'indoors' I can improve throughput a bit but still not excellent - throughput is heavily asymmetric (downlink faster than uplink) Detail: I notice that I'm not the only one, there are similar reports: http://forum.mikrotik.com/...

Throughput question

Hi, I'm evaluating the following setup: - RB912 carrying a Ubiquiti SR71e card in the miniPCIe slot - (the RB912's on-board radio is disabled) - 2 low-gain omni antennas for the SR71e - a laptop a few metres away - a desktop computer directly-connected to the RB912's ethernet port I'm measuring thro...

Low throughput question

Hi, I'm testing a setup with an RB912 with a Ubiquiti SR71e Mini-PCI card. (I'm using the SR71e in my tests, the RB912's on-board radio is disabled). I have 2 low-gain omni antennas, and a laptop several metres away. I don't seem to be able to get TCP throughput (measured by scp-ing a big file) grea...

Re: Wireless disconnected, group key exchange timeout

Hi Sergey,

Can you post what support wrote? I'm seeing deauth due to inactivity (not as frequent as you), I'm curious to know the reply.
