Authentication required

[Ljf1958]

Hi! When I try to access certain websites (many that require login), I get errors: "authentication required" with spot for username and password if on chrome.

On Firefox, error reads: "signupgenius.com [or whatever site trying to access] is requesting your username and password. The site says: "NETGEAR Orbi""

When I do enter any user Id password, I get a 401 error.

What can I do? It seems a security issue?

Thank you

PS appears to be happening on all devices flowing through Orbi internet including phone. I can't get on these sites via my phone either if in wifi mode. I can if on LTE

Do you have any other router hooked up to the orbi?

We are occasionally experiencing this issue as well on selected client machines.  Didn't find a pattern yet. 

Our Orbi is hooked up to a cable router (AVM FritzBox 6940).
