Zoom told me that TWC should be using the .6 software and they(Zoom) had no control over that, they (TWC) told me the updates are automatic and they have no control over when they are done. My problem mostly is that the internet speeds are eratic, more so than they were with my old SB4100, which is a very old modem. I was hoping for a better bump in speed and consistency. Mostly, the reaction of the Zoom rep when I told her that the firmware was 22.214.171.124, was more like uh, oh...that's old software TWC is using! And a lot of what I read elsewhere, said the Zoom 5350 was having a lot of problems with this software and the .6 software addressed this, any thoughts? So far it seems like "upgrading" my equipment was a waste of time and money!
