ARRIS (G18) - Cable Modem Router Combo - Fast DOCSIS 3.1 Multi-Gigabit WiFi 6...

This is great replacement for my older motorola surfboard modem/router combo that I got back in 2011 to use with spectrum. It was older docsis 3.0 and needed to be replaced. Also easy to call cable company and have them enable it. The gateway menu options are similar and easy to navigate and wireless network setup is easy. The firewall now allows for other devices on my network that require other (different) ports. Before I had to keep setting on low (all ports opened) but now I can keep on medium for more safer network. Works great with 1gb network ports with cat 6 and wifi 1gb (current ISP is about 400gb). No issues with it so far. Love it!

We dropped out of expensive renting with x finity to this modem and I’ve seen no difference in reception. Set up required a brief phone call to x finity. It’s important that It contains a router or it won’t connect to your wifi. Don’t ask me how I know!

I hesitated to write a bad review, but thought this might keep someone else from the same mistake. I have Arris products before with no problems. This time when My old cable modem was dmaged by a freak power failure, I saw this one listed as "used" like new. So I orderd. That was almost two months ago. Frome the beginning I had intermittent problems, but they would go away before I could troubleshoot. My sreaming would suddenly buffer, websites took forever to load, my wireless devices would lose Internet connection. Moral to the story...buy the NEW device! It will cost you way less in the long run.

Have been using for 4 months and works well. Get nice signal throughout house. Speed works well for remote work. Only giving 4 stars because originally thought it arrived defective but turns out it just needed to be factory reset like 6x before it worked correctly. Haven’t had issues since. Small and no noise.

it works as well as a basic modem router combo should, if you are looking to do multiplayer gaming, i'd recommend doing the G20 version at least for the increased upload speed. But if your doing general internet use and singleplayer experiences, this will work. You will be required to make use of a phone app, SURFboard. And the app is a bit weird at first, and really i would give this product 4 stars if the app was specific to this modem cause there's a setting allowing you to combine blah blah and blah blah and until you switch this on you will feel like your just making passwords for nothing. Your ISP, for me was Spectrum, may also offer a free cell phone and cell phone service as part of the internet service.

Our cable/WIFI circumstances change and we needed an upgrade; Arris cable modern router has filled the gap.

Very weak! Always buffering and losing connection!

Our old unit was about 8 years old and this unit seems to be quite a bit better. Seems a little faster, we don't get bumped off anymore, and might be a little bit clearer. Overall, very happy with it. And it does work with Optim Have had this unit for quite a while now (9~10 mos.} and it has performed better than I could have hoped for! No problems, only a smooth, steady connection to the internet. The only problems have been with my provider, but other than that just an awesome experience!!!
