Since you are in an open frequency you can't count on you getting data across the links every single time so the ping time increases as the retry occurs.
Nothing seems wrong here. Maybe there's an issue with the persons complaining and not knowing the technology and such but nothing in this post tells me it's broken.
so i got a wireless internet from a local isp , but sometimes my DNS ping time goes as high as 300 ! but when everything is normal its around 2-3 ms.
my ccq is above 90% , and signal Strength is around -60 and Signal To Noise 40 db
also the frequency that im using has a very low usage , and i changed to other low usage frequencies and the problem didn't solve( my bandwidth is empty when the ping time goes high and ping time to my access point and my radio is 1ms since im using a lan connection)
my isp says its because of the noise around the area that i live !!! but wouldn't that effect ccq or signal Strength ? and when the ping time goes from 3 to 300 my CCQ or my signal Strength does not change !
so are they lying to me ? is there a problem with their routers or something ? or can it be actually the noise from my area ?
also my radio is mikrotik sextant g 5hpnd
PSA , when the DNS ping time goes from 3ms to 300ms , the signal strength , CCQ or signal to noise , non of them changes ! so it just goes from 3ms to 300ms all of the sudden without any change to any parameters !
and distance is 14km
