SBG6580 - Unbale to access the GUI page, it shown as invalid password. I found a post from someone having the same exact problem. The answer didn't help. I had a power problem recently, and when fixed, my network was showing 'Motorola' as a network name. I tried connecting my tablets to it and they connected no pronlem. But then I noticed under security it said 'none'. I powered it still the same. Finially, did a hard reset. Got back original name. Got tablets, and phone online. Then tried to access the web manager. Logged in using admin & Motorola. Took me to 'change password' page I entered admin, and motorola, and new password 'Oops! Invalid current user/password'. I've tried motorola, the wifi key, with and without spaces. I've tried another hard reset. Power reset, and finally, ANOTHER hard reset. I manage to get to the change password page no problem. But no matter what I enter for user name and password, I get 'Oops! Invalid current user/password' Pulling my hair out here. I broke down and ordered a SBG8300 today. Since Xfinity upgraded my service
