I think we have the same underlying issue

What model NG gateway product do you have? 

What Firmware version is currently loaded?

Which ISP are you connected with?

What brand and model Wifi device are you using?

Does this happen with ethernet connected devices? 

What channel configurations are currently set on the router?

Please post a copy and paste of the modems connection status and event log page.

I think we have the same underlying issue. I tried messing with netgear support last year. All they ever do is "go to settings and check/uncheck this box" then wait and see if it's fixed. Did that about 5x and to no avail. It's very annoying. I got the router replaced because our older motorola router had better success with uploading and connection overall but lower speed. Still would have the occasional issue. Just frustrating spending $400 on a router/modem and there's issues. 

 

Good to know I'm not the only one with connection/uploading issues.
