Long-Wifi Problems
Model : WA7210N
Hardware Version : latest
Firmware Version : Latest
ISP : haztech
I have two long range wifi that connected at 2.35km MPtMP (multipoint-to-multipoint) N-LOS as following below:
1. TP-Link WA7210N + TL-2424B 24dbi antenna as receiver @ HazTech (look at figure)
Run over 27 dbm transmit power
[*]Avg Signal strength PtP at: 23-32dbi (maintained signal at 25dbi)
[*]No LOS, thats why 2.4GHz is preferred over 5Ghz (above the WA7210N is CPE510).
[*]Channel: 9
[*]Mode: 802.11bgn 150Mbps
[*]Installed at 20meters from earth-ground ontop the roof
2. Altai A2-Ei 14dbi antenna dual-band as Transmitter @ MKHTower (look at figure below)
Run over 31 dbm transmit power
[*]SSID: Mukah-Marhazli
[*]MAC Address(es): **-19-BE-30-96-84
[*]Avg Signal strength PtP at: 20-27dbi
[*]Channel: 9
[*]Mode: 802.11gn - 130Mbps (20MHz)
[*]Installed about 100m (2nd phase) from earth-ground @ 150m height 4-legged telecommunication tower.
So, the distance (via Google Earth is around 2.35km)
At first (after restarted the receiver), I had this reading while survey:
But after few times of "Refresh", I had this:
(During peakhours/daytime)
(during night-time)
Plus, the packets keep lossing everytime I (from receiver) ping'ing the Transmitter IP Address
So, I have no ideas why the ping's keep lossing AND the ping is high (normally 0-5ms, but I had 50-2000ms) however both Receiver & Transmitter are linked all the time (will not disconnected forever, links are stable). I'm not sure if the interference might cause the problem or anything else. It's been almost 3 months to find out the issues/causes but still. These are the alternatives that we had done during the issues.
Mode: bgn to n/bg (not works, keep losing packets)
[*]Channel 1-13 (not works, keep lossing packets)
[*]Re-Alignments (25dbi the highest so far where 25dbi is the exact PtP degrees)
[*]20/40Mhz to 20Mhz (not works, keep losing packets, but 20MHz is preferable due 3-times over-lapping (20Mhz) instead of 1-time over-lapping (40Mhz).
[*]Changed 2.4Ghz to 5Ghz (totally no reading due NLOS because of the obstacles; jungle)
