This is probably router related, so I don't know if you can still help me.

My latency on mobile spikes to about 1800-2000 for about 1 second every 3-4 seconds, makes the game kind of unplayable for me on mobile.  This only happens at home though, on both my phone and tablet over wifi.  If I'm on another wifi network I don't have the problem, so I think it's my router.

I have a linksys 2015 model AC router, 75/50 fios internet, a Galaxy Note 2 phone and a Galaxy Tab S tablet.  On my desktop and laptop everything seems to run fine over wifi, it's only on the mobile devices that I get lag spikes.  However, this isn't isolated to RSCRev.  I also get the lag spikes on my mobile devices at home on Hearthstone.  So it makes me think there may be some router setting that needs to be enabled/disabled or something.  Any ideas?
