Pretty simple.
I was setting up my 7600 surfboard, and it never prompted the activation sequence. So, I called Spectrum, and they informed me that they cannot activate it because it is not on their list of approved modems, routers, or modem + router combos.
Please. If there are any website editors here for Arris. PLEASE REMOVE THE SPECTRUM COMPATIBILITY CLAIM FOR THE 7600 MODEL. It no longer works and I wasted nearly $200 on this piece of junk.
If any officials read this, please contact me, this straight up is NOT okay.
