ARRIS (S34) - Cable Modem - Fast DOCSIS 3.1 Multi-Gigabit Cable Modem, for Co...

Very impressed. This is a solid cable modem and up to date. While I'm not an expert, this replaced my previous ARRIS and it's an improvement. Speeds are solid, set up was easy, although boot up time did take a bit, but that's expected. But it works fantastic with our internet and it's better than anything you can rent from them. No issues with it after a few months. You won't be dissappointed

I have only had this Modem for 48 hours, so this is a preliminary review. I have been a Cox Communications customer for over 20 years. The only problem I had with setting up this Modem was that the first customer service representative I spoke with did not properly save the HFC MAC ID number. So, initially there was no internet and this particular representative scheduled an appointment for a technician to come out. The next morning I called Cox back and spoke to an entirely different representative who caught the error, and now the Modem is up and running. I have only 1 Gigabyte service at the moment, but that is more than adequate for my needs. I have the router ethernet cable plugged into the 1G port. The Modem works just great. I am now able to access a website that is monitored by Cloudflare that I was not able to access with the previous outdated Modem. For the first 48 hours, I can say my internet connectivity and website access have considerably improved. Only time will tell how reliable this Modem really is. I believe it was a worthwhile investment - no more paying rent to Cox, and the Modem is "future proofed" for 2.5 Gigabyte service. I am thankful the second Cox representative was able to resolve the internet connectivity problem resulting from the incorrectly saved MAC ID number. If the conditions surrounding this Modem change, I will edit the review.

Set up was easy and performance is great

Excellent cable modem with fast upload speed. Prior reviews said that the unit overheats. I was concerned about that before I ordered it. But it is actually quite nice. The unit is not too warm.

I had the SB8200 for many years, then I decided to upgrade to the S33, just to see if it would make a difference, it did, but it was underwhelming and probably not worth it, except that I was able to help a friend with the SB8200. But then the S34 finally came along. BOOM! Instant upgrade from 1.2gbps (1200mbps) download to 2.0gbps (2000Mbps) download and the upload speeds are now 300+mbps with the S34, up from 40mbps with the S33! Practically exactly as advertised by the ISP! This is all thanks to the OFDM channel on the upload signal. Good stuff. Arris has typically been very reliable and even though this cable modem gets very hot because of where it is located and it’s lack of additional ventilation, it is still handling nicely. Definately place it in an open area if you can, it will get very warm/hot. I have the LED off under normal conditions, which is great because you can easily tell if something is going on because you’ll see lights flashing instead of nothing. If it’s powered down, that will be obvious because the network will be down. There will be some growing pains with the new equipment and getting the ISP to adapt and create better automated systems, but it did get detected and connected automatically in just a matter of a few minutes. It was just an issue with the ISP when it came to getting a separate router connected and back online. They had to learn how to send a proper configuration to the cable modem, which they did, so that was good. But you can easily connect directly from the back port of the cable modem to check for a good connection, then it’s just a matter of having the proper settings on the cable modem (which the ISP controls) and on the router (which you control, and sold separately). That’s where they (the ISP) need to learn, so that they know an external device/router will always be connected to this cable modem. All good though, the instant upgrade was VERY noticeable, files upload MUCH faster than before, video conferencing is very smooth and reliable. Its great. Excellent, would recommend. Definately buy this instead of the S33, get the S34 instead!

Habe meinen Internetzugang getrennt mit Modem + Router (FritzBox 6660), keine Abstürze mehr !
