Netmetal5 3x3 AC indoors

RouterOS Wireless Networking
1

Hi Guys,

I’m trying to set up Netmetal5 3x3 to substitute my current ASUS RT-N66 router indoors. It’s pretty simple setup there Netmetal will act as simple AP Bridge. No other 5Ghz networks in chosen frequency. But I still see no performance boost switching from ASUS (802.11n 3x3) to Mikrotik (802.11ac 3x3).

Clients in my network are 802.11ac iMACs/Macbooks, using the same 3x3 chipsets.
The distance is 5-10m to Mikrotik.
Antennas used are 3xOMNI 5db/5Ghz. http://www.eurodk.com/en/products/indoor/omni-antenna-5ghz-5dbi

I’m measuring speed between two wifi clients using iperf. It sometimes peaks at ~120Mbps. Also, the speed drops every 10-15s as you can see in the chart attached.

Any suggestions?

I doubt you’re going to see much improvement from station to station throughput using regular 802.11.

The only difference will we number of stations the AP is going to serve on a steady manner vs the RT-N66, and again using plain 802.11 (which you’re forced to when using “standard” stations like the macs) isn’t an optimal PTMP setup like it would be when using nv2, which may be the figures you have as a reference.

Make sure however you’re using the latest firmware/ROS on the netmetal.

Ok, I just tested against two identical stations (iMac 3x3 broadcom chipset), and ASUS is still show better results.
No drops and better speed. But still old ASUS superior to newest Mirkotik. See files below.

I also tested N-ONLY on Mikrotik, and it still has worse results then ASUS.

Any ideas how to boost Netmetal performance???

i think this is an indoor wlan wifi deployment

5

check on netmetal the registration table to see the tx and rx datarate and ccq of the station when doing the throughput test

test the lates ros and use the cm2 package, that suppose to improve performance

6

I don’t understand why cm2 package will improve performance. I have just one AP in ap/bridge mode and I do not need management software for it. Am I miss something?

You missed the changelog…

8

wireless-cm2 is not just capsman. it is a new wireless driver and much improved in all areas.

9

Is it possible to have a list of improvements? What if wireless-cm2 is used on AP and wireless-fp on clients? Is wireless-cm2 improved also in multi point?

10

yes, there are many improvements, hard to list all, because drivers are improved in general.

11

Does it improve performance also if wireless-fp is used on the clients and cm2 on the AP?

a waaaaaaaaaaaaaay better!!! that’s an answer!!!

3x3 ac client / 3x3 ac server:

Normis, any advanced settings for a new driver we should know about?

PS: I got better results (peak speed at 197Mbps) when turning bridge mode = off in wireless interface settings. Any ideas why?
