  • Solid connection
Size: Cable Modem Router (Single Unit) Style: DOCSIS 3.1 - G54
The previous three modems we've owned have been made by Arris, and very solid and reliable. So my expectations for the G54 were very high, especially considering that the cost is one of the most expensive on the market for a combo modem wifi router. It is very easy to hook up, with a power cord, incoming comm cable, and then whatever you decide to add for direct connections. The automation within this hardware is the most advanced that we've experienced. This will auto reset, and do a number of different steps (many which are beyond my comprehension) to ensure the connection is solid and to maintain accessibility. In testing the other wifi signals in our area, there is no interference or competing signals at the WiFi 7 range. Even for the lower ranges, the G54 is excellent about placing our signal in low use channel. All that to say, I've enjoyed this device for the last several months, and now feel like it was worth the cost since we've had excellent coverage ever since the initial connection was established (and sorted out with our provider). ... show more

  • Not Worth The Spend
Size: Cable Modem Router (Single Unit) Style: DOCSIS 3.1 - G54
Poor signal quality in a 2,500 Sq. ft. home. Definitely a step down from my Motorola MG8702. The 8702 would still be in use if it hadn't started dropping devices and packets after 5 years of heavy usage. Anyway, back to the WIFI throughput. 1st - There is an XBOX One 25 feet, line of sight, from the gateway and throughput dropped from an average of 400Mbps to 60Mbps with the switch to the G54. 2nd - Devices, like my reef tank controller workstation (on the 1st floor) no longer connect when the WNIC previously had 4 bars of signal strength, 40-50ms ping response, and no packet loss issues. 3rd - The app does not sync device naming customization with the console interface. In fact, not much syncs between the console and the app which seriously impacts streamline configuration. Also, the app and the console have different configuration options from one-another making it a struggle to verify all settings. 4th - The logs do not work at all. I have tried using the app and 3 different browsers (Edge, Chrome, Brave) on 2 different workstations with no luck. Power cycle did not resolve the issue as noted in troubleshooting. 5th - (My own fault) No VLAN segmentation, or advanced security options available. My network consistently hosts 44 - 50 devices at any given time The guests range from computers to mobile to TV to IoT, and not having the ability to segment these systems to their own VLANS is insane for a solution that costs more than $500. Needless to say, I am less than impressed with the functionality of the ARRIS G54 Gateway and will be seeking another solution in the near future. Live an learn. Ohhh something positive... The wired LAN works great... For the single attached device. ... show more

  • Great Router/Modem combo, highly recommended.

  • Always connect 6 Ghz for fastest speed.
Size: Cable Modem Router (Single Unit) Style: DOCSIS 3.1 - G54
Was able to setup the modem without any issues. However for someone who is not tech savvy the setup may not be easy. Also the modem configuration has a option "Split Mode" which splits all the frequencies. This is super important feature as I was migrating from an older modem. So someone who is not tech savvy might have difficulties. The phone app is average and is not that useful. However once setup I am very happy with the speed, which is why I bought the modem. A important thing to notice when I selected the 6 Ghz frequency that is when I got the fastest download speed on speedtest. For 5 Ghz and 2.4 Ghz the speeds were slower. 5 Ghz speed was around 450 Mbps and for 2.4 Ghz it was around 300 Mbps. So to get the fastest speed device must be connected to 6 Ghz channel. I might need to add an booster as 6 Ghz signal is weak, but it gives the desired speed. ... show more

  • Cannot recommend
Size: Cable Modem Router (Single Unit) Style: DOCSIS 3.1 - G54
I can’t really recommend this to anyone. I’ve now had it for six months and I wish I’d bought differently Setup was relatively easy and the app and device interface are typical and average for the industry. Activation required a call to my Internet provider because of the modem and router being integrated. It also means that you can’t self update firmware, which is frustrating. It’s also proven stable for the most part (complete outages have all been on the network end). However! Two big problems. I’m in a heavily congested area (condo life) and the range is abysmal. Like 100 feet as the crow flies and signal quality drops precipitously. This could be worked around in some sense. But the real backbreaker for me is the firmware controlling the WLAN’s quad band routing. With 36 devices ranging from home control (lights, sensors, etc) to whole home audio streaming (Sonos and Roon) and computers ranging from 2018 to 2026 models the intranet routing is terrible. The problem is the quality of the WLAN and its inability to let devices on the same SSID see one another if they are on different bands. That is, an Apple TV connected via WiFi often fails to see a server connected via Ethernet to the router. An Apple Mac mini connected via Ethernet cannot see a Google Nest. I constantly get errors and disconnects referring to “make sure XX is in the same network”. They are. Same SSID. Full access to internet. Just cannot see one another. No reboots, resets, or changes to configuration seem to resolve this. The only difference is one device is connected via 5GHz and the others via say 2.4 or Ethernet. If you have a relatively simple and consistent WiFi needs (eg; all devices run on WiFi 5 or 6) you are likely fine. But in my mixed device world this thing just does not work. ... show more

  • My old device was better!
Size: Cable Modem Router (Single Unit) Style: DOCSIS 3.1 - G54
Terrible reach! Based on reviews and as much as we paid, I expected much better. No way this has up to 5000 sf coverage! Our device we had previously that was becoming obsolete and would no longer update had better reach and connectivity. Our outdoor cameras go offline now, and our TVs have sloooooow to no connectivity, except the one in the same room as this device. I do not recommend based on our experience I wish I had stayed with my old device. ... show more

  • Worth it!
Size: Cable Modem Router (Single Unit) Style: DOCSIS 3.1 - G54
Very easy to set up, and super fast speeds. Speeds seem to drop the further you get away (20 feet or more), but still seem decent enough for the products I'm running in my house. I haven't been tech savvy for more than 20 years due to family life , but I was tired if my old standard linksys router and Motorola modem set up constantly dropping service with Xfinity, and wanted to save space with a modern all-in-one router/modem combo. This i gambled on not knowing ANYTHING on Arris, but it has made me say "Linksys who? Motorola who?" I haven't had dropped service once since I switched to this gear. I think set up maybe took 15 minutes between the surfboard app, and my Xfinity app. I recommend this product for the average consumer like myself. ... show more
