I don't have a website and no plans to - if that is what you mean, Rich. I will need to log in remotely, however. As will IT support, for maintenance.
That may be part of the reason for specifying that particular router. They may just be more familiar with it. If they have to set up something like updating the Internet connection, reserving a LAN IP, setting up QOS, setting up port forwarding, or whatever else they may need to do on the router, they know exactly where to look for it.
In fact, I got a hold of Motorola and the tech, without hesitation or caveat, said it was designed to do what I want (allow occasional, low volume workstation connection to the internet through the server)
Lucky you! According to
this article, the device is not supported by Motorola. That doesn't mean that they won't talk to you if you happen to get the right tech on the line. It just means that there are no promises that they will. These sort of devices are custom-manufactured and marketed to ISPs, not consumer; and part of the deal is that the ISPs will provide the support. You happened to get lucky.
I personally would
not use a combination modem / router owned by an ISP for your purposes. I ran into that situation with Frontier. Even though Frontier's support was U.S.-based and much better than average, it just got annoying to have to call them every time I needed some simple setting changed on the router.
They did give me the router password, but there were two passwords on that particular router, and the one they gave me didn't give me quite the access that I needed. That password would also have given me access to some technical, troubleshooting, and provisioning-level stuff to which Frontier didn't want me to have access, because as in your case, the modem / router had been custom-designed and manufactured for Frontier, not for direct sale to consumers.
I wound up buying my own router simply so I would have full admin access to it. That's also what I would strongly recommend you do, if you were my client.
That's not to say that you need the exact router that your consultant is specifying. It sounds to me like you just need a standard commercial-grade router that complies with the bazillion different safety and security standards for same.
In fact, I just took a [very] quick look at the HP MSR1002-4 AC, and I'm not quite sure why they're recommending it, either. It doesn't look like it would be my first choice for a client with needs like you describe. I suspect it has something to do with the company's levels of familiarity with and confidence in that particular device.
By the way, despite the "AC" in the name, that router doesn't look to me to have wireless capability. You would need an access point or possibly an expansion card. That's also something I usually recommended because the failure rate for wireless stuff is higher. It makes no sense to toss (and have to reconfigure) a business-class router because the radio fried during an electrical storm. I preferred either a separate AP or a replaceable wireless module.
Unfortunately, I'm not current enough to tell you which router
would be my first choice for you. The posted specs don't tell the whole story. Some routers with great specs have horrid performance (and occasionally vice-versa), so recent experience also comes into play when making these decisions. Someone else will need to chime in with current recommendations for commercial-grade routers appropriate for small-business use.
One thing I wouldn't use would be the modem / router owned by the ISP, that only they could administer and that wasn't designed for business use. It would present multiple access, configuration, performance, reliability, security, and potentially legal problems. I'd put it in bridge mode and put a business-class router behind it.
