Hi there people o have a 5ghz link which is about 2km long. Site A has a 27dbi 5 GHz grid, r5h mini pci card and an rb433.

Site B has a 24dbi 5 GHz grid, r52h mini pci card and an rb433.

Site A is located near a river, so it is much lower than site B

My problem is that the people from site A say that their voip quality is sometimes very low. What I tried was is to set both sides to use 12mbit data rates. And the ccq is 100/100 when no traffic is moving. But when there is traffic then the ccq will jump between 89 and 100.

The signal strength is between -62 and -80, TX signal strength is between -69 and -82.

Signal to noise is between 22dbi and 36dbi

The client does not reconnect or loss connection. Traffic usage is very low on the connection.

I don’t know what else I can do. The mounting poles are already at maximum height and secured with stay wires.

Oh yes I also use l2tp tunnelling to allow remote site to run on same ip range.


PS: there might be some trees in the way, I am not sure.

try to lock datarates at up to 36MBit both sides

then signal fluctuating ist not as much - hoppfully it will be better.

Hi sonny i have added QOS using mangle and queues to all my rb's The voip is much better.

Hi,

what mangle rules do you have added?
can you share?

My pbx uses port 6000 udp so i edited the mangle rules and made port 6000 connections priority1(time critical). So far it is working gr8.
