Note: This model is also a model that Comcast currently rents out. Avoid purchasing any used units as you may be purchasing an un-returned rental that you won't be able to activate. Only purchase this directly from Amazon and in new condition to ensure that you're getting an unactivated product. Make sure you keep any documents relating to this purchase in case Comcast tries to begin charging for rental fees claiming that this gateway is theirs and you are renting it from them. You must provide proof that it's yours to remove the rental fee if they try to claim it's theirs. This is a common occurrence with Comcast and it'll be an even greater occurrence considering it's a primary rental gateway of theirs.
The modem part alone isn't that bad. I can receive the advertised speeds with this modem(but it depends on how congested your area is).
The rest of it is sort of the problem.
One of the main downfalls for this device is its range. It's probably one of the worst range devices any ISP offers. On top of its range being incredibly short, I was also unable to connect to any websites with a low end 3 bar signal because this gateway was too weak to respond back to my device.
You can put this device into what's called "bridge mode" which shuts off its router/wireless functions, but it left me with many connectivity issues. When it was in bridge mode I could not connect to a few services. Some services would make this gateway just not want to respond to anything for a few minutes at a time(even though the connection was still stable). Taking it out of bridge mode made it work properly again, but it defeats the purpose.
This gateway will also broadcast an open "xfinitywifi" network in most states. This will allow anyone nearby to use your gateway(power/split connection) to connect to Comcast. If you're in an area with a lot of cars driving by, your wireless will only slow even more to a crawl as many phones try to automatically connect to it as they drive by.
You can turn off this signal, but it's usually hard to get the setting to stick. Many people have it turning back on randomly or after a firmware update(which happens quite often with these gateways).
By purchasing this gateway, you're pratically giving Comcast yet another free hotspot they can use to charge people to connect to with "xfinitywifi" as any guest/passerbyer must either login with their Comcast account or pay to access this open network.
In the end, the technology on this device is somewhat outdated already. It has a 8x4 channel Docsis modem. 16x4 and now 24x4 channel modems are going to become incredibly common soon. The wireless only features up to 270 Mbps using a 2x2 antenna system while being single band only. Many newer devices are featuring 3x3 systems and are dual band. With such a steep price, it will take months for it to be paid off in terms of the cost of the rental. By the time it's paid off in comparison to rental fees, it'll already be quite outdated. Only purchase this if you feel like you're going to use this for many years and are ok with being behind in technology. If you do purchase it, like always, make sure you only use wireless channels 1,6, or 11. Any other channel is going to make your performance suffer even more and it'll eventually lead to your network getting crushed by others.
If you really want to own your device and need a replacement for your voice service, get the TM822 instead.
Update: Since my original review post, Comcast has been pushing newer firmware that even if you turn on "bridge mode", Comcast still leaves the wireless radio on which continues to allow xfinitywifi and a hidden network to broadcast. Same goes for if you disable wireless on the gateway. In other words, even if you turn on bridge mode, disable wireless, and disable xfinitywifi, your TG862's wireless radio will continue to be up and running broadcasting a hidden ssid and it's technically never shut off.
Update 2: In my review I mentioned to get the TM822 over this. Since then, Comcast has been making it harder to activate that modem for customers who buy it. If you do get one of them instead, please be prepared to deal with a little trouble getting it activated.
Update 3: Since the last update, Comcast has worked with Arris to make the TM822G available through retail purchase as well. You can purchase it on either the Arris Surfboard site or from the new Amazon listing. As always when buying from Amazon with these modems, make sure it's sold/shipped by Amazon. I would highly suggest you buy that modem only over this at this time. However, at the time of this update, 8x4 modems(the TM822G and TG862G) are becoming a bit old and will soon not be eligible for speed upgrades on some of the higher Comcast tiers. If you plan to use this or the TM822G for internet service as well, I'm having a hard time suggesting people buy these when they may be obsolete for some in the near future who want to receive speed upgrades. Keep that in mind when purchasing.
Now for the Infinity TG862G-CT here is what I know:
1. This is the only 'retail' residential gateway you can purchase IF you have telephone and internet from Comcast. I verified this through both Comcast and Arris. Basically you are going to pay for the Wi-Fi and 4 port router whether you use it or not. In my case I use a separate NETGEAR Nighthawk Wireless 4 port router which has proven to be an excellent performer.
2. Your individual experience with Comcast on this is highly dependent on the agent you get. My experience was both good and bad and very time consuming. You might as well hook up the unit which is the easy part of the entire experience since it takes you maybe one minute to put your connections in. At this point you will have neither phone nor internet and you will be calling Comcast hopefully on your cell phone. They will need some serial numbers from you and then they will 'provision' the device. I had tried to call before I disconnected my old one but it seems Comcast wants to make it as difficult as possible. Having a cell phone to call Comcast is key.
3. Arris will tell you that when you speak to Comcast and it is time to configure how you want the residential gateway regarding the Wi-Fi portion you are going to need to ask Comcast to speak to a Level 2 or Level 3 Technician. In my case I did not want the Wi-Fi on at all and simply wanted the unit to function as a 'bridge' to my NETGEAR Nighthawk. Sure enough until I could get a regular agent to transfer me to a Level 2 Technician it was like communicating with an alien. Once I was connected to a Level 2 Technician everything went along much better as we were speaking the same language and he knew exactly what was required. It turns out that only Comcast on their end can make this unit function as a 'bridge' unit. You will not be working with software on your end trying to make this happen so actually that is a good thing. It probably took 30 minutes for the Technician to call me back on my Comcast landline phone once he had taken all the information down. So then my phones were working and the light on the unit said the unit was online so I hung up and went to my wireless devices and my hardwired desktop only to find that none of them were working. So I called the Arris technical hotline because you get through to that immediately and that technician was very helpful and after some complicated troubleshooting he determined that although my phone functioned normally my internet had not been properly 'provisioned'. So back to Comcast and this time just a regular agent was able to 'provision' it properly and bingo we had internet.
4. If you do use the unit as a 'bridge' unit for internet (and I assume most people will because there is no way this will be much of a wireless unit unless you are standing next to it) then Arris recommends that you use ONLY one of the four ports on the back of the unit.
So in the end I replaced my leased, older, simple unit which did everything fine but cost $10 per month which in my case meant I had paid Comcast $600 for the previous five years. You are not allowed by Comcast to purchase a 'retail' unit that is simple and would provide phone and internet. 2 minutes to install it physically and way over an hour on the phone with Comcast and Arris to get it to function properly. There was a certain satisfaction with walking into the Comcast Service Center and getting my receipt for their simple unit and ending my $10 per month charge. Does it make sense to purchase this for $200? Flip a coin. It will take me 20 months to break even assuming I stay with Comcast. The unit I turned in was certainly very profitable for Comcast.
Five stars to Amazon for their customer service. Four stars for this unit for two reasons: 1. You are forced to take a Wi-Fi capable unit even if you don't want one and 2. $200 is a high price.
