Howdy,
I just installed the nighthawk xr1000v2 to replace my xfinity router/modem, and combined it with a gigabit+ modem. I am getting 'terrible' speeds wirelessly now, compared to what i was. When I do speed tests, I pull up to about 300 or 350 mbps, and I was pulling, with xfinity, up to about 700mbps. Not sure why, if my settings are screwy, or what's going on. I've turned off qos, which helped, bumped it from like 60mbps to 300mbps, but besides that, haven't been able to get it to increase beyond that on any of my devices. Right now I'm the only one using any devices, so it's not like other people are reducing my bandwidth.
Note: I pay for 1.2 gbps
-Thanks!
