This is my personal opinion. You would be better off with a regular modem with a separate router.
Gateway units (modem/router combo) are problematic. Range of wifi signal may not be very good. If the unit goes bad it makes it more difficult to troubleshoot to see what the problem is.
You did not mention who your ISP is but most of them offer home phone service.
Do you have phone service through your ISP? If you do, you may or may not be able to purchase a telephony modem.
You do have options.
1) Get the gateway device and use it for your WiFi.
2) Get the gateway, put it in bridge mode (if your ISP allows this) and use your own router. Bridge mode turns off the wireless function of the gateway so you can hook up your router to it. Depending on who your ISP is, you may be able to disable bridge mode yourself. With my Comcast gateway it was easy to do from the modem configuration page.
3) Purchase a regular modem and use your router.
Whether to use pay for each month for the providers modem or get your own is a choice only you can make. You have to decide if buying one is better in the long run for you.
As for suggestions regarding which one you should buy, you will need to find out if your ISP has an approved modems list. If they do, it is likely that only a few of them are available for retail sale.
You don't want to buy a modem then find out your ISP does not support its use.
Here is why I use my Comcast modem in bridge mode and my router.
When I had to use my gateway for a few days in July due to my router going bad, I had a horrible experience with the gateway after I took it out of bridge mode. The plan was to use only the gateway for a couple of weeks, then buy a new router.
While the signal was good every where in the house, my speeds went down and were slower than a turtle.
A 30 second download took an hour.
Another one that should have taken less than a minute took all night and it still had not finished downloading by the next morning.
I got a new router a lot sooner than I had planned on getting it.
Each person has a different experience using the gateway unit. You will have to see what it does for you if you do not want to use your router.
