Zoom Telephonics AC1900 Cable Modem/Router (5363)

I average 175Mbps down and 22Mbps up with this modem and my Comcast plan. I recently converted to Comcast. It has been a nightmare so far, but I can't get the same speeds with other providers in my area. I definitely was not going to be paying the $10/month modem lease fee and wanted a modem that had integrated WiFi, so this modem was an affordable choice. I am using this modem with Comcast's fastest residential plan, the Extreme 150 (150Mbps down/20Mpbs up), but this modem is listed as an approved modem for all of their residential plans.This modem gets similar speeds to Comcast's XB3 modem, but it is more consistent with this modem, especially the WiFi signal.Setup was relatively easy. It would not automatically activate on Comcast's activation site for me. I had to call them and provide them with the modem's MAC address and serial number. After a few automatic restarts, the modem was up and running in about 10 minutes.I am using an Obi VoIP device, connected via Ethernet to this modem, and it works fine. I have several phones, tablets, and laptops that are all connected via WiFi to the modem and they all have great connections throughout my three bedroom, two bathroom home. The 5 GHz band doesn't have as good of a range as the 2.4, but that is the nature of the beast and it is completely normal. Devices within decent range have much faster connections over the 5 GHz band than the 2.4.As of the time of my review, the product description does not mention Guest Networks. The router on this modem DOES have the ability to create guest networks... a ton of them actually. You can create several different guest networks on both the 2.4 and 5 GHz bands and have different passwords on each. By default, the guest networks do not have a password on them when you first enable them, so make sure you add a password to them so people don't leach off of your connection!There are MANY advanced options available in the firmware, like port forwarding, parental controls, firewall, MAC and IP filtering, bridging, VPN, etc. If you have a specific question about whether or not this modem has a feature, feel free to leave me a comment and I will get back to you. I am not a networking expert but I can look in the firmware for you if you need information about it. See the comments section for how you can block common ad serving sites using Parental Controls.The firmware interface IS clunky, as others have mentioned. It is a little awkward to navigate at first but anyone who is familiar with router firmware should be okay. Just remember to change the network band on the first page and then visit subsequent pages to edit the settings for that band. To edit the settings for the other band, go back to the first page and change the band there.I give this modem/router combo five stars, despite the firmware interface. It has so many advanced features and great wireless range. It's nice not to have to deal with a separate router, or pay Comcast $10/month anymore for their modem.

Had a Zoom 5352 which had been fine until recently when the speed started dropping off so I chose this, as much for compatibility with my existing network setup as anything else, plus it offers higher speed wifi than the 5352. Generally speaking it was a simple matter to login to my old modem and duplicate the network settings onto the new one (hooked up to a laptop via a cable). However I did encounter one problem and although I was able to work around it, others may not be able to. For historical reasons (back when I had multiple routers on my network) I had my network set to use 192.168.15 as the base IP address for all my machines (using DHCP on most of them) and I had a machine with a fixed ip address based on that (that did not collide with the DHCP assigned addresses). I used port forwarding in the old modem to connect to it from the internet (it's a web server). Although I could change the base IP address of the 5363 to 192.168.15, the port forwarding page would only show 192.168.0 as the IP prefix. That meant I was unable to port forward to my static machine which had a fixed ip address in the 192.168.15 range.However since I no longer had multiple routers I was able to switch to using 192.168.0 as the base Ip address range and I reconfigured my static machine to use the same range (although my linux is a bit rusty so it took a while).In the end it all worked fine. Zoom support confirmed that there is a bug in the software and that while a fix is in the works for the next firmware update, it may take "many months" (their words) for the fix to make it out into the real world and into my modem via my cable provider.Software version with bug is 5.510.3.4Other than that though, I am quite happy with it so far.

Just got this modem router combo last week. The current modem/router that TWC rents out for their service is still on 802.11n, and costs about $10 a month to rent. It's time to switch out.In the box you receive the power cable and an ethernet cable. Plug it into the coax into the wall and you're directed to a step by step setup. Didn't even need to break out the manual. The setup is simple enough that I was able to do it in about five minutes, and actually has a pretty good number of features for more advanced users.In the span of 13 months, this modem router will have paid for itself! Not only that, but it's also much more reliable and faster than the Arris modem being leased by TWC. On my old modem/router, connection would be inconsistent and randomly drop out. With this one, it's blazing fast, and we've had zero problems so far. Will update if anything changes!Some of the noteable features of this modem router:Beamforming Technology!At first, I had some suspicions that beamforming technology were just some marketing gimmick, or that the effect wouldn't actually be that apparent. However, I am now able to be on the first floor, outside of my apartment building (my apartment is on the fourth floor) and still be connected to the home wifi. Granted, it's not as speedy as if I were inside or closer, but I am connected and it's usable nonetheless which I find to be pretty amazing.Future ProofThe modem functions of the product are limited to 343mb/s down, which is pretty good for now, but even in the event that that number becomes too low, the unit is also an AC1900 802.11ac router. Most routers of this speed would cost you $150+ alone, but for $134.99, you get a modem that provides more speed than ISP's offer, and a router that'll be useable for a long while.QoSQoS is quality of service, and it allows the router to automatically allocate bandwidth as needed to different devices. If you're doing something heavy like gaming, QoS will allow you more bandwidth in order to ensure a smooth experience. If you're just surfing the net or browsing amazon, you will be allocated less bandwidth. Through this, everybody gets enough bandwidth for a speedy experience, with nobody's activities impeding another.Overall, great modem/router combo. Great price, great features, great specs.Save yourself the monthly $10 on rental fee's AND get better internet.
