metal 5shpn PTP channel width 20/40 above or belwo ?

hi i need the best setting for my link . i need 40 mbit peer second at least

21 miles ptp link with two 31dbi dish + metal 5shpn on both side vertical

1-what the best 20/40 above or below can someone clear thing to me ?
2- what is the best setting on both side



thanx

no replay i thought that !!!

Did you even bother to set up the link?
Did you even bother to search for a tutorial?
Of course not.
Work first, ask questions later.

ok thank u for your awesome answer !!! i’ve been work to setup my link for 2 week now and i done .

i needed help my station side reseive 40 m but my station tx is bad ccq for tx 3 to 10%


So we must to guess that…
Btw why do you use 6040Mhz?
Most antennas don’t work very well in that frequency.

ok her is another change i turned multicast helper to full

on both side tx ccq become better know 60%

and this is a pic of my setting

see if there is any wrong with my setting

set the same freq and choose same above ore below on them both.

Why do you use that freq? do the antennas support that ?

I think your setting is wrong. If you select Frequency 6040MHz you need to add this frequency on other side to Scan List. -79/-75dB is not a good signal level. We like to see -50 to -55dB as perfect link and to -61dB as acceptable link. Everything over 70dB is wrong for us.

ok thanks guys . because i can’t get better signal for that distant 35 k i removed my link to near tower 24 k .
and thanks for correcting my wrong setting i will fix that .



peace

after remove my link the distant 24 kmeter
signal 43/45 ccq 100/100 perfect link

43/45 is actually too strong. You should turn down your power a bit on both sides.

i have metal 5shpn set on the default value (ithink its 31 dbm ) how much i should set it ?

Turn it down a couple db at a time until you are in the mid 50s. Are you using NV2?

use nv2 for wireless protocol.

I agree. You will get a good bit more throughput.

ok i turned on nv2 but after that i couldn’t connect with pppoe everything ok but pppoe . i turned back to nstrem every thing back to normal is there any setting with nv2 that i sould apply ?

Please send to support@mikrotik.com the support output files from AP and Client which are using Nv2 and where the PPPoE doesn’t work.

my ap and my station just ptp link with no pppoe server or pppoe client . iam trying to log in with pppoe via windows and it dosnt work with nv2 as a protocal but it work fine when i use nstrem

and her image to explain the case

Try Bridge Mode: Enabled to AP and Station Bridge to Client.
