Solution
NOTE: There is NO external hard drive via USB connected. Just a printer via USB 2.0. Or offline and disconnected. The WLAN problem still persists also with disconnected USB devices. The only solution was to re-route the antenna cables within the router, at least in this case.
(a) Re-route WLAN antenna wire within your FritzBox 7490
Before (with WLAN problem):
After (fixed WLAN problem):
- Move antenna calbes away from USB ports problem zones.
(b) Maybe also use just USB 2.0 instead of USB 3.0 within your router settings
(c) Put your router device on a top location within your room
Place your router NOT to the ground floor. Maybe locate it, hand it on a wall etc. Make sure the device get good air flow for cooling.
