First let's narrow the scope of the issue - is this an installation
issue or point of failure issue.

Did it work in the past? If it didn't, its an installation issue. If
it did work, but failed...something "broke".

I could go on with things to check for both situations, but the would
be too lengthy.

>From what is sounds like, you are describing a system where you have
an access point that is back hauled to the NOC 5 KM away. Since the
customers (the ones using the access point have problems), you may
have either a back haul problem or access point problem.

Plug your laptop into the ethernet output port on your far-end back
haul radio and see if you get a good radio connection to your NOC 5 KM
away. Most radios have a signal quality indicator on the configuration
web page. If you have a good signal, you may have an access problem.

In Benin City, Nigeria?

At 5km, you should have at least 10 meters clearance for the Fresnel
Zone at midpoint:
<http://www.terabeam.com/support/calculations/fresnel-zone.php>
That means the antennas at both ends must be at least 10 meters above
ground level. Do you have the necessary clearances?

I assume you have the 24dBi antenna at the customers, and something
else at the NOC. It takes to radios to make a link. What antenna,
coax, and radio are at the WISP end? Numbers please.

If you have more than one customer with a problem, then it's more
likely that the problem is at the central access point end, and not at
the customers (CPE) end.

Are you sure it's lack of signal strength (weak?) that's the problem
and not interference? How weak? What does Dude return for signal
strength and noise level? Numbers please.

You might want to graph the signal level:
<http://wiki.mikrotik.com/wiki/Graphing_Client_Signal_Strength>
That will tell you if it's varying and how badly. If the noise level
varies substantially, you have an interference problem.
