| [Fixed] Canopy - drops out every 1-3 min...help
My WISP just did a tower change and upgrade, after which I had to have them out to re-align my 900mhz antennae, which has worked fine for 3 years. When the service guy got here he couldn't believe that I was ever getting service in the first place, and moved the set up to a tripod/pole on the peak of my roof. Under the old set-up I was getting a power level of around -76dBm.The new location is better, ranging between -65 to -72 dBm, with the jitter jumping between 1-4 (sometimes up even higher). Problem is that the unit drops to -114 dBm every couple of minutes, rescans, re-registers, and all is good for another few minutes.
Example:
Subscriber Module Stats
Session Status : REGISTERED VC 35 Rate 1X/1X
Registered AP : 0a-00-3e-94-cf-a5
RSSI : 1744
Power Level : -65 dBm
Jitter : 2
Air Delay : 55 approximately 1.53 miles (8085 feet)
Subscriber Module Stats
Session Status : REGISTERING VC 0 Rate 1X/1X
Registered AP : n/a
RSSI : 7
Power Level : -114 dBm
Jitter : 0
Air Delay : 504 approximately 14.03 miles (74088 feet)
Subscriber Module Stats
Session Status : REGISTERED VC 35 Rate 1X/1X
Registered AP : 0a-00-3e-94-cf-a5
RSSI : 1739
Power Level : -65 dBm
Jitter : 4
Air Delay : 55 approximately 1.53 miles (8085 feet)
Is this a problem with the new tower location, aim of my antennae, new interference, or something they need to fix on their end? I don't know much about this technology, so any help/input would be appreciated. |

Beyond that there is nothing you can legally do on your end. Contact your WISP. |

I'm having the same problem, well sort of. Mine does what you're describing once in awhile, usually does it for an hour or two then it's fine. Just curious to what was causing your problem and how you resolved it. |

Most common cause is probably interference. The next would be a Fresnel Edge Refraction, usually called a 'bad bounce'.
Solution for #1 is to either eliminate sources of interference that are drowning out the tower signal or get a stronger signal so that the tower is stronger than the noise.
Solution for #2 usually requires raising the antenna to 'get out of the bounce'. You might need to go up a foot, or maybe 20 - the only way to tell is to try it - a good installer should be able to tell most of the time when a bounce is happening.
To the OP - my guess as to "why it ever worked" would be similar to number 2: you were getting a bounce that was sustained and in phase, but that is just a guess.
