Using laptop for streaming DirectvNow issue

My laptop is a few yrs old, but was overkill at the time so it still runs everything great EXCEPT DirectvNow. I have it hardwired into my wireless gateway. My speeds run about 105Mbps down. Seems like every minute or so it is like I hit a pause button....

Comparing two routers?

I have a chance to get a high end linksys and I have a high end Netgear. If you were me would you upgrade. Yes high end is subjective. But would it be a step forward? Most internet comparisons are sponsored and I don't trust them. Two routers are:
NETGEAR - Nighthawk X6 AC3200 Tri-Band Wi-Fi Router (old)

Linksys - WRT32X AC3200 Dual-Band Wi-Fi Gaming Router with Killer Prioritization Engine (Maybe new one)

Thanks

Need some Roku help please

I have a Roku 2 (about a year old..Sling promotion) ethernet connected, hit about 90Mbps down. DirectvNow wants to buffer a lot (I know they've had their issues) but it also resets a lot, I can push the home button, screen appears, but app sound continues, uninstalled app, Roku is up to date. Tried wirelessly and it's all about the same. Is my Roku 2 dying? Can't find much online help..(tried Google). Any thoughts? Thanks. Andy
