These other devices are probably not surrounded by water either.

Most of the time the dosers are placed inside stands and surrounded by the display tank above and sump beside or below it. The doser itself connects only to a 2.4ghz band. Although 2.4ghz does much better than 5ghz in terms of range, it can have a difficult time maintaining adequate signal strength if it is tucked away inside a stand and surrounded by water. Here is where the router comes in...

If the router signal strength is not enough to communicate with the doser, you will see longer load times.

One way to rule this out is to temporarily switch the SA Doser to LAN mode and connect an Ethernet cable to the doser and your router. If the speed improves, then that confirms the issue being signal strength related.


When you connect, have you tried comparing the speeds between connecting through your network vs. myGHL?
What were the results?
