Comcast kept telling me I needed to upgrade my modem to take advantage of my 'blazing' 400mbps speed that I am overpaying for.I bought this combo as I have always found Arris to be reliable, it was towards the top of their compatible list, and had great reviews. It is a nice sleek looking unit and being a combo takes up a lot less room.First off you HAVE to use the comcast app to even get it connected which would be fine except I live in the country where there is no cell service. The last Arris installed a lot easier. An hour later and 2 trips to town, I finally get it to work.First disappoin
This review is for the Arris Surfboard G34. I purchased this combo modem/router to replace my old one. When using Cox, note that you can't just plugin the new device and start using it -- you always need to call their technical support team to have them unregister your old device and register your new one.The setup process was easy and straight forward. The most difficult party was getting through to Cox technical support. My previous modem/router used DOCSIS 3.0 technology, so this upgrade gave me a 45% increase in download speed and a 366% increase in upload speed; all without changing my se
Below is my original review. Arris made good on replacing the Surfboard G34 DOCSIS 3.1 Gigabit Cable Modem & Wi-Fi 6 Router (AX3000). I had spent time with Sparklight support confirming that the original one had stopped working. I reached out to Arris Tech Support and after 3 calls they were convinced it was a faulty device. I re-installed an older modem I had and sent back the original one (after getting the RMA and shipping label from Arris). The process went well and within a couple of weeks I received the replacement. Went through the setup and got everything setup. I'll see how long this
Briefly: this Arris G34 works!As my main concern was about activating it-this review is about activation process only.Activation with xfinity app was eeeeasyyy!!!!( just online with their xfinity app for cellphone) no tel calls, no technicians were needed.And for technologically clueless senior it took about half an our maximum. I found all info I needed through my personal “best friend” - google :) After the modem connected and appeared in the list of local WiFi’s ( with names which are on the label of modem - 2 actually, one for each band- 2,4 and 5), so I first connected the cellphone from
Xfinity is Horrible.. I pay for 400 Mb upload and 400 Mb download bandwidth, I get only 80 Mb download and 11 Mb upload. I have my own brand new(6 months old) Arris Surfboard G34 DOCSIS 3.1 Gigabit Cable Modem at home right from beginning of this service. When I signed up for this plan, I got 400 MB speed for a month and everything was excellent. Later on Xfinity did some upgrade in my area, which made my internet speed drop to 80 MB. I have a Xfinity technician friend, he confirmed it, he said if I call Xfinity they will send technician home and complain it's the issue with Modem and not thei
This is, by far, the worst Arris experience I have ever had. The modem part (Arris's real expertise) is fine but the router part is junk. The app & customer support are beyond bizarre. I regret this purchase.1) The smart phone app is a disaster. It hangs up in the middle of installation, it somehow can't find connection to the service. Once installed, it continues to regularly drop connection to the network when everything else on your network remains connected. It makes configuring and setting up your router a nightmare.2) Phone support for installation support is beyond bizarre. I was connec
I love the look of this modem/router combo as well as the convenience of having one unit instead of two. The reviews for this were so mixed but I had purchased one for my daughter in the fall so I went ahead and ordered again. She has said that she's experienced internet skips but mostly impacting phone calls - she uses wifi calling because, you know, verizon. Anyway, connecting this unit for her was pretty simple even though there were some compatibility issues with ring cameras.Based on the reviews I did not use the Arris app - I used the website which was super basic. Got everything set up,
