I cant get more than 50 Mbps through a PtP Netmetal 5 link

Reflection occurs when your station receiving its AP signal from more than 1 line !!!

when your Fresnel zone is not really clear you AP signal reflects from near obstacles to your client , then your link could be very unstable , sometimes you get 100 Mbps(feeding from real signal) suddenly drop to 10 Mbps(station feeding from reflected signal).

** Fresnel zone is not Line of Sight , may be you have complete LOS but your Fresnel zone is not really clear.

here is a good explanation :

Reflections are generally a indoor issue rather than signal reception issue outdoors?
There is several easily identifiable items outdoor which can cause reflections such as a nearby metal building or perhaps the worst case is where a link is over the sea and tides cause havoc?

try adjusting tx power all rates fixed and using 5dbm tx power

Is it real test? Do you really achive on this link more than 1,4Gbps!?!? :open_mouth:

Hi, yes, it´s real… why I will false this test?

1434Mbps / 8 bits = About 180 MBytes, tomorrow will test with a Gigabit ethernet port computer and try to make a test with iperf… today make a iperf test but two sides PCs are connected through a wifi router and max speed are 3 Mbytes. The real test will be done tomorrow.

Regards!!

Hi, I tried with all rates fixed but bad results, and the results of the picture (about 1500 Mbps) is with card-rates config and lowest dbm (-30)… the signal still in -49db

Regards!!

Mikrotik reports maximum performace at 990Mbps, your results are almost 50% better: http://routerboard.com/RB922UAGS-5HPacT-NM
IMHO WiFi connection should be slower than ethernet one so 1,4Gbps on WiFi is quite strange. How do you want to “feed” WiFi with “so slow” 1Gb ethernet port :slight_smile: ?
Are you aware of “Lost packet count” ? Isn’t it too high ? If you loose e.g. 50% of packets then the connection speed seems to be acceptable as real one is at 700Mbps.

ok i think then mikrotik equipment is not adjusting the TX power at all


i think you have to report that to support

Oh my god !!

you need 300 or 500 MBps not Mbps ?!!
your current link is perfect man , i don’t think so there is a radio which carry 500 MBps !! it’s too much,what you are gonna do wit such a crazy speed ? even a link could support that speed , what device are you using to use that amount of Data ??
what is sender or receiver HDD could read/write 300 MBps ?!!!

even a Lan cable carry 1000 Mbps , network speed measuring standard is bps not Bps

Edit : for a real test use tcp not upd and use random data , if not satisfied on tcp use 2 independent link and setup an OSPF to achieving full duplex

Oh sorry a lot, I have edited my first post, I need 300 to 500 Megabits per second… I put wrong MegaByte instead Megabit…

If it’s Netmetal5

than it is a QCA9880 chip, so max speed is 1300Mb in wireless level (1.27 Gbit/s). How you could get more?

Hi!
I think our freind is measured the device “local address”, i can reproduce the same “througput”. :slight_smile:
