mANTBox 19s and SXT Lite5 very poor Tx/RX CCQ

stefki · September 19, 2016, 8:42pm

Hello, few days I go I purchased these two nice devices and I spend almost 3 days without sleeping to make best settings for 4 Km link. Unfortunately I got very poor transfer and CCQ.
These are configs from my mANTBox and SXT Lite5. If someone experienced user can give me some help and hints, thank you all the best.

I have tried also with SXT HG5 ac on AC band I can’t get even 50 Mbps transfer.
I don’t know why CCQ is low.

InoX · September 19, 2016, 10:59pm

Try:

nstreme
5200-5600Mhz
Your signal is to low, the link is obstructed or missaligned. It should be around -60. Lower channel might resolve that.

stefki · September 20, 2016, 7:40am

@InoX: thank you I change to Nstreme and 5600 Mhz and I get much more improvements on my CCQ. almost 90%. Great!!

But my second SXT lite 5 which is on another area in the city don’t want to connect to the same MantBox19s. It’s reconnecting all the time.

I got this log

be sure of wireless settings of your sxt .

stefki · September 20, 2016, 2:42pm

The settings on my second SXT lite 5 are the same as first one. I found strange bug here, If I disable security profile on mANTBox19s my second SXT Lite5 is connected. But If I enable profile1 then don’t want to connect.

InoX · September 20, 2016, 8:18pm

Maybe passwords don’t match.

stefki · September 20, 2016, 8:46pm

I found the problem , the mANTBox was in Bridge Mode, I switched to AP Bridge and both clients are connected now.

laithmikrotik · September 21, 2016, 9:44am

kristaps · September 21, 2016, 11:19am

And what speed, and CCQ you can achieve now ?

stefki · September 21, 2016, 3:08pm

I am pretty newbie in radio technology, are the results are ok ?
These are my results:

I don’t know why SXT HG5 AC gives only 140Mbit transfer on Bandwidth Test , how I can get 400 Mbit transfer on AC mode ?

Thank you all.

InoX · September 21, 2016, 6:05pm

You can’t. Not at 4km. Maybe 1km.
Also in btest, limiting tx and rx speed to 70+70mbps will give you exactly 140mbps.

stefki · September 21, 2016, 8:40pm

what do you think about my results ? Are they are ok ? Could be better ?

antonsb · September 22, 2016, 12:24pm

Please don’t run bandwidth on any of those boards. You have to run bandwidth through the created link.

stefki · September 22, 2016, 4:17pm

@antonsb you mean on this kind of bandwidth test ?

Between the ends of the link two PC’s ?

10.10.14.10 is mANTBox 19s distance 4 km

antonsb · September 22, 2016, 5:08pm

You are now running mANTBox cpu at 100%.
Generating traffic takes a lot of resources. Put a more powerful RB at the end of link (3011,1100.CCR series) or run traffic between two PCs on both ends.

stefki · September 22, 2016, 7:13pm

How many clients can handle this mANTBox 19s ?

leonix · September 23, 2016, 8:11am

You should use a QRT5ac instead of the Sxt for the 4km distance. However, my experiences with AC-Technology on noisy enviroments (many other 5GHz links at the same tower) is bad. In case your environment is noisy you should exchange the AC-Router with older N-Routers (eg. QRT5 instead of a QRT5ac) at least at the noisy site. N-Devices perform much better.

InoX · September 23, 2016, 9:41pm

Why not LHG’s?

stefki · September 29, 2016, 7:28am

One technical question to Mikrotik advanced users, how many clients (SXT’s) I can connect to nstreme protocol ?

kristaps · October 4, 2016, 1:16pm

there is no software limit for SXT in AP-bridge mode but for best possible performance up to 25-35 client is suggested.
