A few weeks ago we started experiencing an issue where some users couldn't get internet access in the office on the WiFi but others can with no problem. The devices could be from an iPhone, android tablet and even Windows 10 laptops - the weird thing is they will all connect to the WiFi but get the message No Internet, secured. I have even tried a different router and the same thing happens.
DHCP addresses and DNS are from an SBS 2011 server so I am wondering that maybe an update has done something on there but am at a loss where to look because as I say its only certain devices that wont connect.
Any thoughts would be greatly appreciated.
