Metal 2shpn problem

Thu Mar 06, 2014 8:18 pm

I just bought 6pcs brand new metals 2shpn all bundled with 6db omni antenna (known as latest release). All stocked with 5.26 lv 4 and firmware 3.10 (upgraded to 3.12). I tried to do bandwidth test:
Mikrotik Server (AMD Phenom II x4) > Mikrotik Metal 2shpn > Laptop (Atheros AR9287 mPCIe bgn 2x2 MIMO)
Settings: ap bridge, wds off, 802.11n only, 2412 HT40 above, 802.11, no security, distance 2km, noise immunity ap+client, tx power (tried each step from 16 to 32), mode bridge.
Signal looks good at laptop, 150mbps stable, ping stable, but bandwidth test using windows bandwidth test utility as follow:
Laptop connecting to Mikrotik Server, mode Receive, only got up to 21.7mbps, then drop below 10mbps for few seconds, then back to 20-21.7 then drop again. Metal CPU utilization only 13-17%.
Laptop connecting to Metal, mode Receive, only got up to 17.6mbps, stable, but Metal CPU utilization at 100%.
Laptop direct connection to Metal's LAN port, can get 82.3mbps, stable, and CPU utilization 100%.
I tried set Metal to 20MHz only, and bandwidth stable at 12mbps.
All my metals are not usable. Bought trashes for total USD 600! WTH!!
My question is: IS THIS A KIND OF JOKE? MY OLD CHEAP TP-LINK WA5110G can even get 24.5mbps stable at 802.11g 20MHz.
A Cheap Buggy Firmware TP-LINK WA7210N can even get 42mbps stable at 802.11n HT40.
And guess what? A toy from UBNT called PicoStation M2HP can get 73mbps STABLE at exactly the same location and situation.
I'm satisfied with Mikrotik OS, but I'm really disappointed with Mikrotik Hardware!
Just a suggestion: If you guys can't make a good hardware, then just focus to do software! Peoples who buy your hardwares mostly are provider/professional/enterprise, and we are expecting better performance and reability compare to cheap plastic newbie toys!

(sorry for my bad english)

WA5110G and PicoStation M2HP have little gain antenna, and WA7210N have directional antenna.

I sell those products, the picostation are so much fragile, I stoped sell the picostation because too much time the power transistor for tx is broken after some week or month.

WA7210N is a mess of fw version, each more o less incompatible with another, but it have the better (directional) antenna among those type of products.

The 6db antenna included in package are too much sensible than the other, also the hardware.
If any interference of any nature reach the antenna, the signal is poor than the other less sensible antennas.

Generally the adaptive noise immunity or hw protection modes must be turned off if you want to connect any devices without problem.

What do you want to do exactly? An hotspot or a connection only from the Metal and your laptop?

The Metal has only 10/100 port, do not use high HT data rates, they never reach more than 95Mbit/s bi-directional.

Use RouterOS 6.7, the 5.x is unsupported and from 6.x+ the 802.11 protocol has been improved.

If you want to use cryptograpy never use tkip or wpa on 802.11n or ac, only wpa2 and aes-ccm are supported

This is a script I use in my metal, used as hotspot inside a little city, on the port, on the marina and on the 30km of beach (10km, the small city, and another 20km)

/interface wireless
set [ find default-name=wlan1 ] band=2ghz-b/g bridge-mode=disabled country=italy default-forwarding=no disabled=no frequency=2462 l2mtu=2290 max-station-count=62 mode=ap-bridge radio-name="HS" ssid=HS tx-power=23 tx-power-mode=all-rates-fixed wireless-protocol=802.11

Each AP are distant 400 - 500 meters in city, on the beach are only on bathhouse, and the channels are interleaved (but the same 3 channels....) each point have two sxt 5hnd, one for receive and one to transmit to next point, instead on the beach are only one sxt connected on another unique stx as PtMP
Working all well with 10dB antenna and with other competitor active near the HotSpot, also on same overlapped channels...

Well my PicoStation came with 5db rubber duck antenna, and my WA5110 came with 5db rubber duck antenna too.
WA7210N tried using external antenna from WA5110. So all about the same situation.
The problem is, why toy wifi can do much better throughput compare to metal?
If metal worse than toy, then what metal is? Garbage?

I don't now what it is but a hear match things that metal groove not so good.

I have grooves running (not metal) and the working like a charm.

If mikrotik not responsible for metal issues, I won't use any mikrotik hardware anymore. Enough problems with RB450G, RB2011, RB1000, and now Metal!

I got PicoStation M2HP from my hardware archive
i was playing with it recently. i used its own AirOS & OpenWRT too, but it is struggling with throughput.
in AP Mode i got 9Mbps Down & 10Mbps up maximum.
can you please guide me is it hardware or software issue?
in datasheet they claim throughput of 100Mbps, it should do at least 50%

But what's the point of resurrecting a topic from 6 years ago?
However they are bulls–t, as I already wrote 6 years ago.
