Title: Xfinity mid band capable on return patch for fast upload speeds... i.e. 300 Mbps.
Review: I had an S33 Arris cable modem and upgraded to the 2 Gbps download speed tier with 300 Mbps upload speeds at Xfinity from Comcast. However, my modem would only upload at 40Mbps. I had a truck roll to my house and was told that even though my modem claims it supports 2.5 Gbps up and download speeds, that the modem did not support mid band connection on the return path. So, I purchased the S34 Arris cable modem and activated it and ran a speed test and immediately had the 355 Mbps upload speed and 2300 Mbps download speed which I was previously unable to obtain the fast upload speeds that I was paying for. The Connection Status channels report page inside the modem showed a new 5th channel on the return path that uses the transmit method of OFDMA which my S33 modem didn't have. Apparently that channel allows the higher speed uploads of 355 Mbps. Both modems have 34 download bonded channels and 4 upstream bonded channels, but only the S34 Arris modem has the 5th bonded upstream channel of type OFDMA. So, if you're in a bind of not getting more than 40 Mbps upload speeds on the 2 Gbps speed tier, I highly recommend that you upgrade your owned modem to the S34 model!

Title: Arris SBG8300 - Excellent Gateway, No Problems after 1 Week.
Review: I purchased this ARRIS SBG8300 gateway new from Amazon for $177 in May 2024 to switch from AT&T DSL2+ (copper landline) to Sparklight cable internet service (100 MBps down/ 10 MBps up). I decided to purchase and own it myself, rather than pay rental fees- it should pay for itself in about one year. I wanted an established DOCSIS 3.1 design (3.1 is required by Sparklight) that could handle possible future cable bandwidth upgrades, and this gateway seemed good for that. It has 32 x 8 channels for DOCSIS 3.0 and 2 x 2 channels for DOCSIS 3.1, and can theoretically handle up to 4 Gbps download speeds, so this is probably way more gateway than I need now.The Sparklight installation tech told me that this was the first time he had encountered a new customer who provided their own gateway in my rural MS town. This turned out to be a minor problem, as he had always been given the gateways pre-configured. Initially, he was unable to get it up and running, and he had to run off to perform other installations (Uh-oh!). But the Sparklight phone support people were very good, and saw that the gateway was simply waiting for a firmware update. Apparently, firmware updates are something that only the cable company can do. Sparklight was able to push the update remotely, and I was off and running.Configuration was pretty straightforward. I should warn potential buyers that the gateway's firewall is set to WEAK by default. I decided to switch the firewall to MEDIUM, and discovered that I could no longer access the gateway configuration page directly using the http:// browser connection. After going to MEDIUM, it only allowed https:// browser connections. So, you have to go through a few extra clicks (accepting the risk, etc.) in the browser to reconnect to the gateway's configuration page. With all of the warnings, etc., it is easy to believe that your new gateway may have been hacked, so be prepared for that. Make sure that you turn off UPnP for added security unless you need that. It is also a good idea to do a port scan to make sure there are no unnecessary open ports that could present good targets for hackers.Performance has been excellent, delivering over the purchased speeds (usually, I get 110 Mbps download and 20 MBps upload via speedtest.net). I have not had a single problem after about 1 week of service, have never needed to do a reset, and the gateway seems to be running cool, just above room temperature.I think that most problems that people experience with cable modems/gateways in general are due to 1) poor line signal quality and 2) WiFi crowding/interference issues. The SBG8300 provides line quality information in the homepage, so you can troubleshoot signal issues yourself and perhaps avoid extra service fees if the problem is inside your home. I did not try the gateway configuration app for wireless devices- all of my tweaking was through a hard Ethernet connection and web browser. FYI the gateway homepage did complain about my Firefox version 126 (some warning about needing at least v 63) , but it worked OK.I guess that the only features that I wanted, but couldn't have using this gateway, are:1) WiFi 6 - this gateway has the older WiFi 5 (802.11ac) standard . But our current wireless devices can't use WiFi 6 anyway, so no biggie.2) No USB port on the gateway. This is very handy if you want to do network printing via USB, or set up a large USB stick as a network drive (NAS).Overall, I really like the performance of this gateway. Time will tell if the hardware is as reliable as it appears to be.-----------------------------------------------------------------------------------------------------------------------7/24 Update- No problems after ~ 60 days, very pleased. After doing a little more research, it turns out that there are some interesting reasons some cable modems fail. It all goes back to the original cable concept as a distribution system for ONE-WAY analog TV signals. Cable modems must both receive and send digital signals. If the DOWNLOAD line signal quality is poor, you will get disconnect/reconnect issues- everyone knows that. But the more serious issue is with the UPSTREAM signal. The cable modems will try to overcome poor line quality conditions by BOOSTING the UPLOAD signal. This leads to greater continuous heat generation inside the modem, and sometimes failure due to overheating. So, the reason some folks need to replace their cable modems regularly is due to the poor line signal quality, not necessarily the modem itself. You can fix this with a special amplifier called an active return cable modem amplifier (Amazon sells these), but the permanent fix is to get the cable company to change out the cabling and components to get a good baseline signal.

Title: Some home Wifi products will not work with Arris
Review: I loved that it was plug and play but I have had a lot of issues with internet and Cox says it is the router but most things work it just drops connections and my thermostat will not work with it. I have called Bryant to the house twice and they have replaced the thermostat and now say it is the modem. After reading more on the Bryant it looks like they recommend linksys for connecting. When the Bryant guy was here he connected over his cell and also saw dropped connections. Again I have called Cox and they say they see no issues so I am stuck and feel I need to buy different routers. I have the same issue at both homes. Right now one is not working at all and after being on the phone with cox for over 30 minutes trying to trouble shoot I hung up again just thinking I need to go back with linksys or even netgear.

Title: Works well with Xfinity
Review: After a number of problems with the Moto MB8611 and a lack of support from Xfinity, I ended up replacing that unit with the Arris S34.The good news: installation and setup were extremely easy, it's been rock solid.The less good news: there's a paucity of LED indicators (only one, multi-mode). Arris strongly recommends using their app to manage the device; I haven't done so because I don't wish to install apps from a vendor as a "one time" use. Their web UI is okay, not great. It's proving to be difficult to automate getting statistics from the device for my monitoring system (but to be fair, it's been so stable that this hasn't been a serious need). I really don't like the fact that it uses TLS but there's no way to update the server certificate (meaning that my browser won't offer to enter the saved password, as it's "not secure").But - it's still pretty much the best experience I've had with a cable modem in years. Recommended.
