I discovered an odd glitch when trying to access LinkSys Router Admin interface via Firefox. I was using the correct user name and password, but I was being told my login was wrong. I was able to get in via Chrome or IE, but not Firefox. I was looking around the LinkSys forums for something else when I came across a couple of posts from other people who could not get in via Firefox. Turns out if you have the Do Not Track (Tools > Options > Privacy > Tracking [Tell websites I do not want to be tracked]) enabled, the router admin will not work in Firefox. Turning this feature off and restarting Firefox I was able to access the router admin via Firefox with no issues.
