Possible Wireless Network Faulty Radio, Need Help

[Prejudice]

Hello there, 

 

I live in South Africa in the middle of nowhere and rely off of wirless radio internet to get any form of outside world connection. I recently switched suppliers for a better line. And they're claiming I have a faulty dish

 

So I have a 30dBm dish, Connecting to a tower of theirs not too far, there was trees in the way but we cleared it up. The signal statistics are as follows
Tx/Rx Signal Strength -65/50 dBm (average)

Tx/Rx Signal Strength channel 0 -70/50 dBm

Tx/Rx Signal Strength channel 1 -60/50 dBm

 

Originally they stated that the signal was too strong, so they slightly detuned my radio so that signal wouldn't bounce back from the tower, slowly the connection has been made better, but im still getting latency spikes with no usage down the line. Or when 6mbps is being using out of 15mbps (max bandwidth) im getting latency spikes of nearly 300-500ms. And on idle there is the occasional spike of 300-500ms. 

I've been running latency tests and trace routes and all the spikes are within their network, they've tuned and realigned the dish and i've spent alot of money on parts and labor. Now the last they're pushing is saying my Radio is Faulty and may need to be replace. However, im only experiencing the latency spikes during peak times of around 5pm - 11pm, then some jitter from 6am - 5pm. 

During early morning hours 12am - 6am. There is near to no problems. But they're pushing that my dish/radio is faulty. Are they taking me for a ride? or are they being genuine that even though I have no problems in the morning but alot at night, it could still be my radio?

at midnite - early morning radio activities is close to none (most people are sleeping), so you dont get any interference.

All wifi, cellular and bluetooth usage in the area will interupt the signal especially at night where people use internet for leasure.

If you have the same pattern i don't think the radio is broken, not strong enough probably.

1. What frequency is the WISP using to communicate with your CPE?
2. What is the make/model of your CPE?
3. How high is your CPE mounted relative to ground level?
4. Visual LOS is not all that is needed for a good PtP link. You have to consider the Fresnel zone effects from other solid objects in the way. You might need to clear more vegetation and elevate the CPE even more.
5. It’s very difficult to escape latency on wireless connections. There can be interference from other wireless broadcasts within the path of the PtP link, precipitation and physical objects. Your observation that latency falls between 12am-6am when internet utilization would be low, suggests that there’s likely wireless interference from other networks in the area; not necessarily close to you where it’s rural, but somewhere along the path to the WISP antenna.
