Just to be sure, this is compatible with cable modems? My downloads and uploads will not be affected, correct?

Did not use it for that type of application. Used it for over the air TV antenna signal and for that it works great.

There is one port that allows bi-directional data transfer. You must connect the cable modem to this port. But then it will work fie. I use mine with Time Warner Cable.

Yes i have it with a cable modem and boosted my conection now is not crashing any more

You can hook a cable modem up to any of the 4 output ports........All 4 are bi-directional......The one with the little red arrow just means you can also power the unit from that leg along with hooking up equipment by using a power inserter to block the power from hitting the back of your equipment. This unit is just a bi-directional amplifier with an internal 4way splitter.

I only use the unamplified port for my cable (Comcast) modem and that works fine.
578235
Yes, it just amplifies the signal coming in through the coax. It does not change it.

I do not know if it is compatible with Comcast. It is a modem-router in one unit. I do want to add that it quit working after about 2 months and we ended up purchasing the recommended device from AT&T.;

It worked for my Comcast service, but I have no idea about Time Warner compatibility.

Hello, I believe you mean coax cable compatible? If you are talking about regular cable outlet cable (like Comcast or similar) yes, it is compatible with that. The only way, this modem can get internet signal is through the coax cable from the wall. I hope this answers your question.

I don't have Comcast but it may be wired universally so it should work no guarantees but it won't hurt to try it with your modem

I purchased this product because Time-Warner, my cable and Internet provider recommended it. I do not know if it is compatible with Comcast but you should be able to go onto their web site to find out. Yes, it is both a modem and router and was easy to install and has worked beautifully for me, a non-tekkie.

I would say that if the specifications or description doesn't say that it is, assume that it is not. There may be other modems that do specify that it is. You just have to do the research even if it means going to the Geek Squad at Best Buy or some other store.

Yes, I believe it will because I am currently using it with Comcast internet and both download and upload speed are unaffected. I added this booster because I was having trouble with on-demand and this cleared up the problem.

I bought one for the same reason - to save the $8/month to Comcast. After many hours and many calls, a tech (not Comcast!), told me that it would never work properly for all three functions - cable, phone & internet. He said their modems have some firmware that is proprietary but they will delight it. Long story short: pay Comcast the $8 and "Enjoy" it!

Should be fine. This is a router not a modem. Routers don't care. Modems do. ;)

Yes, this device is compatible with ALL of Comcast's Internet Tiers (currently up to Extreme 150). You can verify this by visiting Comcast's supported modem site here: http://mydeviceinfo.comcast.net/Please note that this device is capable of working with any major ISP as it is DOCSIS 3.0 Certified. Simply contact your ISP to verify that the model is supported.

Should be compatible with all ISP's. The default IP address of the router shouldn't conflict with any existing ISP modem.

I have a slow cable modem, it's hard to say what "regular" and "higher download speeds" mean to different people, but for my area 12 MBPS is about as slow as it gets. That being said, I run a lot on those 12 megs, so if you had 6 MBPS DSL or something like that you would probably be fine. If you mean a 56k modem, I can't say for sure but I wouldn't bet on any video streaming working out.

This just emits a wireless signal. The modem is normally what you need to worry about being compatible. Based off that fact, yes it is.

It is 100% compatible with COMCAST, VOIP, internet and TV - crystal clear phone. DOCSIS 3.0. I have never seen anything install so rapidly and fully like real bread and butter. Unless COX is from the MOON and totally different than COMCAST cable ... I think you should experience the same satisfaction. The big trouble is finding this modem available anywhere. The full install and firmware upgrade took a full twenty minutes with COMCAST ... all automatic ... one mouse click.

You should be able to use the modem regardless of what level of cable TV service. Internet service is separate.

As long as you have a valid IP address, it should work fine. I am not sure about your particular modem, and if it uses DHCP or not.
