How do I get a new gateway device?
After having DSL dropped and AT&T Fiber installed in my home, the technician didn't replace my AT&T gateway (an outdated Arris NVG589.). Last week I ordered two Air 4921 wi-fi extenders, and was surprised to find out they don't work with my old gateway.
How do I get my Arris NVG589 exchanged for something that does work with these Air 4921 wi-fi extenders?!
