so i bought this recently but this is my second router,First one had a power issue but ran perfectly fine with speed,I have charter spectrum and was getting 110+mbps on the 5ghz and around 85-95mbps on the 2.4ghz band. But once i got this the speeds declined horribly,I can't run past 25mbps on the 2.4 band and wont hit past 40mbps on the 5ghz band! Hard wired i'm only getting 50mbps but directly to my modem i'm getting 130mbps. I'm on firmware version 378.9529,I've tried going to merlin but that didn't work,Tried different channels to no avail. Any reason this could be happening? Btw i'm running a laptop,2 galaxy s6 active's,xbox one and a nexus player.
