My issue is that I have various devices on my network but I am unable to access them using username and password via a browser. for example I have a birdbox camera using 192.168.1.20, I am then asked for user name 'admin' password which is 'null' and on every device on network I am told that password or username are wrong. They are not? I am using a dreytek router and addresses are bound in and on a mac. But it is the same issue on windows and any browser. could it be a router setting? Thanks Frank
