brand new R7000 issues

Here's a few tips that will hopefully keep you liking your R7000..

- (From experience - I have two of them)  When you upgrade this router  always do a factory reset after a firmware upgrade. There can be artifacts between the old fw or config that will cause grief on the router. Either way, it's best to start off with a clean slate.Never load an old version config on a new version of firmware.

-Ensure WMM is enabled on the router, always. 

- QoS I would stay away from form as it impedes the Broadcom Cut Through Forwarding feature, especially if you have a 100+mb connection.

- Pick Wireless  band channels, don't leave in auto mode. Try different channels. especially for 5ghz. (1,6,11 for 2.ghz). When you try different channels, reboot the router.

- 5ghz has better throughput, but shorter distance, as you have discovered. WIFI is based on environment, so not everything works the same for everyone.

- Not all routers are the same. Try getting the router up as high as possible and, in a well ventilated area, ideally, central to your environment. 

- Antennae orientation should be like a "W"  \ | /
