Wi-Fi/router connection issue

[RuthB57]

Hi,

I am having issues with intermittent internet connection. Thursday through Monday none of my devices will connect to the router despite the router appearing to be working correctly (all lights on).  I have tried restarting devices and the router and sometimes get a connection but it only lasts 5 minutes before losing connection.  This is affecting all my devices including my sky tv box. 

Any advice would be greatly appreciated.
