Question: Is this compatible with comcast?
Document: After reading the reviews - I was anxious about buying this - It worked perfectly with our carrier. I would however, call your  carrier and make sure it would be compatible.
I bought this because it has many options and allows usage of the USB connector, such as for a printer or external drive.However, it appears to not be fully compatible with my rural internet provider. So please check into that, if relevant, before purchase.
the TP-Link TD-W8968 Works very good in my office. Thanks so much. I recomended to buy this &Iacute;tem for your home or office
You are also able to set max in case you don't want all your speed being tied up by any device (maybe it would avoid a delay till throttling engaged). It has a very easy ip address reservation tool. I use port forwarding and configured the port myself but upnp is available too. I have a wired bridge for the top floor of my home set up on this (its actually my old netgear N300).
You are also able to give each range (group) a priority. For example I get 4000kbps down and 1000kbps up (its the best we have in our location don't laugh). I assigned my laptop and Ipad in the same group with a priority of 1. I set the minimum download at 2000kbps and the minimum upload at 500kbps. I set the dhcp group with priority 2. My laptop and iPad are always guaranteed the minimums.
Very satisfied with the modem router. I had a westell prior to this with Centurytel internet. I was constantly having to restart the router as it seemed to die just about every day. After deciding Westell was junk I started shopping and decided to try TP. The only thing that prevented me from giving it a perfect 5 was that it would be nice to be able to set up a guest account for visitors. My kids sometimes have friends over with laptops but I really don't want to grant them full network access.
VERY EASY INSTALLATION. WORKS AS ADVERTISED. WI-FI ALL WORK GREAT. RANGE IS OUTSTANDING. I WOULD RECOMMEND THIS PRODUCT TO ANYONE.
This router didn't work, the power led stays awake and the other lights flashed then go off. There's nothing gets connected to it. The reset button didn't work at all. I emailed TP-Link, they offered the replacement, I don't know should I spend another money for the shipment.
This product is not doing it's job. I have to reset my wi-fi almost every week.I wouldn't recommend this product.
This is a review for TP-Link 4-Port 300Mbps Wireless N ADSL2+ Modem Router (TD-W8968).Let me start out by saying that the number one reason that inexpensive modems and combo router devices malfunction and die, is overheating. I have probably gone through 5 modems in my lifetime that all had overheating issues. My last modem from Embarq, the Zyxel 660 was plagued by the same issues, as all the other ones.
Answer: If Comcast is ADSL, yes.
