I've had weeks of disconnects from ESO and i'm guessing its got something to do with the firmware update the Superhub recieved. What once was a reliable connection for 4 years has become terrible, as I post this my 100mb connection is running at 1mb, woohoo!
Welcome to the forum. I'm sorry to hear of the problems that you are experiencing with disconnections on ESO.
We are currently investigating issues with the Superhub 2 and online gaming that appear to be linked to a recent firmware update. We hope to have some information soon that we can share with the community.
When checking your hub I can't see any problems that would cause you to be getting slow speeds. Are you testing through wired or wireless connection?
