And while I do understand the initial appeal to some, the general agreement from experts is that friends don't let friends purchase or use combo devices (you end up with one or more compromises).
The problem is, the large majority of consumers are not "experts", nor do all "experts" actually know what they're talking about ("male answer syndrome"), present company excluded
.
In this particular case, the OP is simply using a very old (by tech standards) product, which ought to have been replaced already. If a consumer is renting their cable gateway, they can simply call the cable company, tell them that it's broken, and ask for a replacement, which should be a current model device.
I'm not arguing that a combo device becomes problematic if only one of its functions breaks or becomes outdated, but that, in the real world, most people's brains start hearing "yada yada yada blah blah blah" when we techies start suggesting a complex (to them) solution of two or three different devices, each with its own configurations to understand, cabling that adds more points of failure, etc. I also acknowledge that cable ISP customers may save money by buying their own equipment, as long as they understand that it will become obsolete in a few years.
I don't know about other cable ISPs, but Comcast has been very good about maintaining a list of the various DOCSIS 3.0 products they permit on their network, and they are now leasing a mesh router solution. Their non-mesh xFi gateway is a fine product, with excellent WiFi performance, and it is required for their own VoIP service. I'm not a Comcast customer, but several of my neighbors are, and I was surprised at how well their gateways work in two-story houses, and they work just fine with OBi devices.
