BAD LINE QUALITY ON LANDLINE
First we have to make sure if we have WIMAX or FIBER
If you have Wimax (First Box) then we have to proceed to step 2.
If you have a FIBER (Second box) Reboot the router and if still not working then please go to step 3.
First of all we have to locate and go to our VoIP Adapter, Now that we have it in front then we have to make sure that there are lights on it and that its turned on.
If the lights are on and the cables are connected then we proceed to Reboot the VoIP Adapter by unplugging the power cable and then plugging back in again.
Now we wait for 10 minutes and then try again, if you still have the same problem then proceed to step 3.
Now we want to check our internet connection.
We start by trying to do a Speedtest, we recomend using this one Speedtest
If the speed is not good enough this is probably the reason for the Quality of the line is bad, you can read more about slow internet on the following guides. Im not getting my full fiber speed or Im having a slow wimax connection.
