I have 3 wifi access points in my house and I have to make sure that I am connected to the one in the train room or throttles are very erattic.?

My JMRI train room Mac is connected wired to the ethernet network. If I had it connected wireless then it to had to be on the train room ?wifi access point. .

None of my wifi access points serve IP addresses. They are all wired ethernet back to my VPN, firewall, router.

I have noticed on my ipads just surfing the net that they will sometime connect to a wifi accesss pint that is not closest. When that happens they usually work but really slowly.?

I can leave one area of the house with a connect to the closest accesss point and go to the other end of the house and still have a full signal strength showing on wi fi but I cannot even open a web page. If I force the device to pick a closer wifi access point everything starts working again.?
