It really is cheaper to buy your own modem, buying one costs as much as renting one for 10 months.

Hey, you could buy a refurbished modem or a brown box modem from Amazon for cheap.

I've bought 2 refurbed units from them and both have been flawless.

The first modem I bought was identical to the TWC modem I had and it was $20 bucks. But at the time, I didn't know it was only a DOCSIS 2.0 modem and also, I didn't realize I was paying for a 50mbit connection but that modem only allowed for about 25mbit download speeds.

I bought a refurbed DOCSIS 3.0 modem for $35 bucks and now my speeds were a little over 50mbits.

My parents pay for a 15mbit connection so I gave them old modem so they didn't have to pay the modem rental fee anymore.

This is the 2nd unit I bought:

This is the correct answer. Pretty sure you can get an intro 100/5 (I think it's 5) for $45 a month for the first year. Jumps to like $65 after that. It's not bad but not great. I'd recommend buying your own modem to avoid the $5 a month rental fee. Something like a Motorola Surfboard 6121 works well enough and you can pick them up used for less than $20.

I'm on 75 Mbps down and 10 Mbps up with Comcast. Personally I would highly recommend Motorola SB6121. I have been using it since 2013, no problems at all. Very solid product. Then you can pair it with a dual band AC router that has 4 Ethernet ports.

We bought the non-retail packaging since it's much more cheaper:

Comcast has a great product with absolutely the worst customer service on the fucking planet. Seriously shoot-yourself-in-the-head service. However, the speeds are great where I am, and we can't get FiOS inside the city.

My parents and in-laws have used both services, and liked both. Honestly, I only have good anecdotes for the core internet offerings of either service. If you have a stomach for dealing with bad customer service, I'd recommend Comcast if the price is better. Otherwise, FiOS all the way.

If you get Comcast, I'd highly recommend getting your own Docsis 3.0 modem instead of renting - it'll pay you back pretty fast and you'll know that you're getting the best possible speeds that way - Comcast was renting me a Docsis 2.0 modem for like $8/mo for the first month I had the service, and the speed improved a lot when my new modem arrived.

Buy your own regardless. Because if you use theirs, you lease it from them so they charge you a monthly fee. You can get this Docsis 3.0 modem for 35 bucks. You're going to need a Docsis 3.0 modem if you want to take advantage of their speeds.

Your issue is actually probably your modem. You have to have a DOCSIS 3.0 cable modem in order to go above 56/57 - I know because I'm having the same issue.

You need a modem like this: http://www.amazon.com/dp/B00768SBAU/

So uhh.. instead of leasing a cable modem for like $7 a month, you can go ahead and buy this for $70.. that will pay itself off in less than a year and works on any DOCSIS 3 cable network.. then you plug it into the WAN port of this for $104, and you now have a gigabit wifi network in your house that is better than anything COMCAST will provide you, COMCAST doesn't have control or access over SHIT, and they don't get to endlessly milk you for fees. The whole setup pays itself off in two years, and every day after that is profits in YOUR pocket instead of Comcast. It's not like they're going to upgrade from DOCSIS 3.0 anytime soon.

Ese es un módem de DOCSIS 2.0. Desde hace tiempo vivo en usa y no se si intercable ahora estára mejorando a Docsis 3.0.

Sin embargo, te recomiendo que consigas uno más actualizado, like this one

Geobaching for 6 - 12 months will make you miss your home setup but after two months of questionable internet speeds and little to no commitment in the property, I figured no loss in trying to tie in with Ethernet after successful test bought a 50 ft run and am pleased with the results, moral of the story never trust ISP rented equipment stuff was probably developed in 1998.

Question: Why go for the USG vs an EdgeRouter?

We have more/less the same amount of devices on our networks and for anyone curious my setup was very similar but a little cheaper:

Switches: https://www.amazon.com/NETGEAR-8-Port-Gigabit-Ethernet-Switch/dp/B00KFD0SYK

When I started I already had my modem but a lot of my equipment I bought used off eBay. Significantly cheaper.

you can get it new on amazon for less than $40.

There is no reason to ride out the rental fee when you can buy a perfectly functioning modem for less than $40. It's not like things will suddenly change that much in four months.

For performance speed (I think 25mbps?) this will function perfectly fine:

If you are paying for speeds above 100mbps you will want a different one though.
