Internet speeed had dropped on my M5, rebooted and seems to be better. However in trying to solve the problem I found by connecting M5 to BT Openreach modem I couldn't get and internet conection.
Original set-up - M5 connect to ASUS router with wifi turned off - works fine until recent speed issue.
Connected to openreach modem - no internet.
How do I solve this if I want to ditch the ASUS router?
Thanks in advance
