An internet provider installed us a microwave link:
The issue is that:
The ping from our side to the gateway is about 1-2 ms, which is great, but it remains like this for only 12 hours, then it start to give latency and time outs 100 - 800 ms.
The provider changes only the channel and the ping reduces to 1-2 ms, i asked them after they changed the frequency channel to go back to the old channel to check if it's a noise issue or not, apparently as expected thing remained 1-2 ms. We have been in this case for two days.
Any one has an idea of what could cause this issue ? or had this issue before.
