S5 really slow on home wifi ONLY

[DFRI]

My Galaxy S5 is perfect on the network, and most other wifi's, EXCEPT mine at home. Tried all afternoon for a fix. Seems like a problem with some other S5's. Driving me crazy.

No other devices are slow on wifi.

I am still on Kit Kat, 4.4.4.

Can anyone help with why it is lagging so much. And should I let the phone update the latest Android version???

Thanks for ANY help.

Having the phone up to date can certainly help, but also resetting your router might help as well since it's only your home wifi.
