I'm having problems where my wifi plummets for periods of time. I've been speedtesting all the devices while streaming Netflix and one Galaxy Tab (old, Tab 2 I think) causes the wifi to plumet. If I stream from new tablets or phones it hardly effects the speed.
Is there some meaning to this old device or purely coincidence?
Netgear N300, Xfinity (about 100 Mbps on Lan).
