Awesome, thanks for the details.
I bought my SB6141 from NewEgg over Black Friday so there's no return for me.
Maybe I could flip it on craigslist but it looks like I'll just have to hold my breath for now.
My 18 month old Zoom 5341J is an 8 x 4 with a full band receiver and working IPv6 support. It cost me even less than I had paid 3 months earlier for a SB6141 that had lots of issues. Both TWC and now Spectrum have approved it for 100 Mbps service; the Motorola/Arris SB6141 is only good for 60.
