I have received many comments from my first Comcast post back in March of 2012 (June 2015 post here). Many people in my area, and around the country are using Comcast and there are many questions about both wired and wireless Internet speeds. Here are my latest suggestions:
1) Comcast has increased their Internet speeds: “Performance” now offers speeds up to 50 Mpbs (up from 25 Mbps), “Blast” is now 105 Mbps, (up from 50 Mbps), and “Extreme 105” has been bumped to 150 Mbps. I have not seen the 150 Mbps offer in my area of Tennessee.
2) Comcast has come out with new Docsis 3.0 modem/routers in order to handle their speed increases. The two that I am seeing in my area of service are the Wireless Gateway 1 and the Wireless Gateway 2. You can rent these modem/routers from Comcast or buy them. I would buy them if I were you.
3) These new modem/routers are very decent. They have four 10/100/1000 Gigabit Ethernet Ports and they will definitely get you the speeds (wired) that Comcast advertises.
4) The wireless capability of the router is not bad (the Wireless Gateway 2 is dual band). If you want more speed/distance, call Comcast toll free (855-308-9452), and have them put the Gateway into “Bridge Mode”. Then you can use your router of choice (make sure that it is a 10/100/1000 port/switch router). I like this one. Even though 802.11ac speeds are higher than 802.11n, I don’t think that they are high enough to justify the higher price.
5) Once the Comcast technician has put the router/modem into bridge mode, ethernet ports 2, 3, and 4 will no longer work (disabled). Connect a Cat6e cable from port 1 of the Comcast Gateway to the WAN port (Uplink/Internet) of your router of choice. Now you can configure your router as you like.
6) Wireless speed will vary (router positioning, house construction and layout, etc.), but it will be very good. If you are paying for the 105 Mbps tier your wireless speeds will of course be faster than that of the 50 Mbps tier.
Please feel free to comment. Let me know about your Comcast Internet experience.
