Comcast cable internet hook up

How do you configure for comcast hi=speed internet?

Comcast has to set up your account. You can not do it yourself. Once that's done, you just plug the cable modem into an ethernet port on you computer.

Comcast Cable Internet not working with router (WRT54G), but network is fine?

My Comcast Cable Internet is not working with my router (WRT54G), but my home network is fine. The internet works without router.
I have a WRT54G Wireless-G Broadband Router from Linksys.
I was using Bellsouth DSL Internet up until two weeks ago.
I had my DSL modem connected to my router, and the router let me use the internet and share some files and printers with my laptop upstairs.
A few weeks ago we changed to Comcast cable. The technician came in and connected it himself, but only for the desktop. The internet worked perfectly, and still works perfectly on my desktop (the one downstairs). He didn't really give me any instruction or CD-roms for it.
When I tried connecting my router, the internet stopped working. It was weird because the router worked for the file sharing and printer sharing between both my computers, but the internet didn't work. Although, the light for the internet is lit on the router itself.
I even have this program called "AOL Network Magic" which shows a map of what is connected to the router, and it shows that the router and my laptop and desktop are connected, but then it has an "X" for the internet connection.
I have tried everything. I lost all of my CDs and things that came with Linksys, but I downloaded some guides from the Linksys website and it doesn't really help. I tried something called "NetSet", but after I set everything up it says my router is not compatible or something with NetSet. I read a bunch of FAQs, I tried going to comcast and seeing if they had any FAQS about it, but I can't find anything.
Maybe one of you can help me?
Also, I don't know my modem's IP address. I had it for Bellsouth, and sometimes when I would lose my connection I would go there and click on "reconnect" or something like that.
So the only way I can use the internet is to disconnect everything from my router and connect the ethernet cable directly to the modem.

You may open the web setup utility page of the router by typing its IP address on your browser's address bar. By default, it is 192.168.1.1. When you're asked for username, you may leave it blank. For password, its "admin". If in case that does not work, reset your router at the back for 30 secs and do a power cycle again, see if it becomes accessible after that...

Cannot conncect PC to internet through wrt54g version 5 (I have Comcast cable internet)

I had my Comcast cable internet installed yesterday and tried to connect my Linksys wrt54g V-5 wireless internet with no success. I have tried running through the CD install setup multiple times (even doing the 30 sec power cycle) and at the end of the program Im told "PC cannot connect to internet". I've also tried switching around different cables and still nothing...
Just to be sure I've done the power cycle correct, these are the steps that I took:
1) Unplug internet cable from PC>router>Modem
2) Unplug router battery (after holding reset button for over 30s) then Modem.
3) Reconnect Modem cable to Router internet port
4) Reconnect power to Modem
5) Connect cable in port 1, 2, 3 or 4 (tried them all) to PC
6) Reconnect power to Router (waited for a few min)
7) Turned on PC and tried the Install program again with no success
I believe I have to clone my MAC # for the router from my PC but I cant connect to internet with the cables attached (or wirelessly) to the modem and the router, but I can get on the internet directly from the moden just fine, and the Linksys shows green across the board when everything is connected...
Is there any other way to clone the MAC # with out having the Linksys attached or would that be self defeating??
Any help would be MUCH appriciated (especially b/c the Comcast folks want to charge us AGAIN to come back out and install the wireless when I specifically asked to have it done the first time...)

Do not use CD to configure the router..You can configure the router manually.
Open the set up page of the router by launching an Internet Explorer Browser and type the address bar, 192.168.1.1 and press enter. When it prompts for the username and password, leave the username field empty and provide password as admin and click on ok.
On the main setup page the ""Internet Connection Type"" should be on ""Obtain IP Automatically - DHCP “. Click on the Save Settings button.Now click on the sub tab ""MAC address clone"".Click on enable..Click Clone & click save settings ...Check WAN Ip on Status page of router .... If getting Valid IP,try going onlineIf not ... power cycle for 4-5 minutes & then again check the WAN Ip address .....

Getting comcast cable/internet...Will it work with my Macbook Pro?

We are getting Comcast tomorrow...we currently have AT&T internet and my Mac is always getting kicked off my internet, onto a "belkin54g" that barely works. This is getting really annoying, but tomorrow we are getting the comcast internet/cable thingy. So is comcast going to work with my laptop O.K.? or will we have trouble with that too? because I am really tired of being kicked offline all the time. Thanks!

It sounds like you're having problems with your router, not with your ISP. If that's the case, and you don't replace the router, you'll probably continue to have the same problems.

IBook and Comcast Cable modem--can't connect to Internet? Please help

Hello everyone!
I have an ancient iBook . Here are the stats:Mac OSX version 10.0.3(told you it was ancient), 193MB, PowerPC G3. I bought it off of eBay about two in half years ago and it didn't come with an Airport card...I only received a laptop, the original box, some cds, and the adapter. I have a Comcast cable modem and I was wondering if anyone could help me figure out how to connect my iBook with the modem. Prior to Comcast, I had Bellsouth and all I had to do was simply unplug one end from my mother's Dell and plug it into my iBook and it instantly connected. However, I can't do it with the Comcast. Can anyone tell me how? Pretty please?
iBook Mac OS X (10.0.x) PowerPC G3, 193MB

You likely need to contact Comcast to get them to help you set up the iBook for your new cable internet service. They should be able to walk you through it.

Airport Extreme & Internet Connectivity - Motorola SB6120/ Comcast Cable

I recently (June 14th, 2010) purchased an Airport Extreme.
I'm having troubles with intermittent drops of internet connectivity.
The router is connected wan side to a Motorola surfboard 6120, and from there to Comcast cable service. Wired LAN side, I have the router connected to another switch. I also use the wireless for my iPad.
When started, the router works just fine. But in ~ an hour it seems to drop the internet connection, or at least stops routing out to the net. There is no LED indication on the front panel that anything is wrong (on both the airport or the modem). And in the Airport Utility, it still lists my public IP etc etc... and there seems (to me) to be nothing enlightening in the stats and logs screen.
Once back on my old router (Linksys), there is no interruption in internet connectivity. So, I'm fairly confident this is the apple router misbehaving.
Any help would be greatly appreciated.

Welcome to the discussion area, jbuffat!
+When started, the router works just fine. But in ~ an hour it seems to drop the internet connection, or at least stops routing out to the net.+
This is a classic symptom of some sort of wireless interference that is affecting the Apple router. It's not unusual at all for one manufacturer's router to work well and another have problems in a given location. I've had the exact reverse of your issue with the Apple router working great, but Linksys slowing down and losing connections.
The culprit is most likely a nearby cordless phone, either yours or even a neighbors. If you have cordless phones there, try turning them off for a few hours to see if the problems continue. If they don't, you have your answer.
A nearby wireless network at the neighbors could certainly be causing problems as well as a new security system nearby.
Without trying to be scientific about this, the easiest probable solution is to start changing the wireless channel on your AirPort Extreme to see if you can find some clear airspace. Keep experimenting until you find a good channel or run out of channels.

I have an apple time capsule and am about to have xfinity cable and internet hooked up in my new apartment. The cable provider said I need a modem that is Docsis3 capable - will my time capsule do the job or do i need another modem? Thanks

I have an apple time capsule and am about to have xfinity cable and internet hooked up in my new apartment. The cable provider said I need a modem that is Docsis3 capable - will my time capsule do the job or do i need another modem? Thanks

The Time Capsule is only a router...with a built in hard drive. It does not have a modem built in, so you will need to use a separate modem with your new calbe service.
If the cable provider offers a modem with their service it would be good idea to use that device, as you know that it will be supported by your provider in the event of any Internet connection difficulties.
If the provider does not offer a modem, I am sure that they have a list of compatible modems on their website, or check with customer support for more information.

Having Trouble getting airport to connect to new comcast cable modem

Help, I'm been at this for 2 days now. I don't know why I'm having so much trouble.   I'm trying to transfer from DSL to comcast cable modem and running into lots of problems getting everything to work.
I can't get my airport extrreme to talk to my new comcast cable modem. I've tried everything, restart the modem, restart and reset the airport. chaning out cables, ensuring the green light is at the cable connection of the modem and the airport.
I can find two issues I can't resolve. one, the 10.0.0.1 webpage for the modem/router doesn't response, pings fail to 10.0.0.1. Yet, my computer is talking to the internet nicely using an ethernet cable to this cable modem. I've talked to comcast for hours, to many different people, over Many hours, and they either say the box is working or hang up on me or transfering me to nowhere land.
The airport never goes to a green front light, and airport utility and always dispay an empty IPv4 address. I've tried everything, and can't get the airport to renew it's DHCP license.
Where am I going wrong? I've search the web, and tried the solutions I found. Is my 3 year old airport too old? or is my comcast box bad? I checked the airport firmware and I'm on the latest version.
After getting this working, I still have an OOMA to transfer over to the comcast modem. Am I kidding my self? Help please.
selina

ok, answering my own question, Turns out, there are three ways to do a hard reset on my airport extreme. Only the last method worked. The easy reset, from the Airport utility menu ( clicking the restore default setting) didn't make my airport talk to the new comcast cable modem. The second way, by pressing the reset button while power up didn't work. The harder third way, hold in the reset button and then plugging in the power cord did work. and the airport is now playing nicely with cable modem.   I wasted how many hours before reading this method in the apple support pages ? and then remember doing this trick once many years ago.
I also wasted a few hours trying to get ooma to talk on the new cable modem, and the hard reset key for OOMA to play nicely with a new modem can be complicated. This method requires it to be connected and working ( plug ooma tele into the older DSL network), hook a phone to it, dial * # * # 0 9 9, (star, pound, star,pound then 099) and saying yes.    That reset it to factory settings letting it reconfigure itself to a new modem gateway.
I still can't get into the gateway web page 10.0.0.1 to change the admin password, Don't advertise that. I get no reply to request or to pings. I think some comcast rep changed a port setting so I can't reach it. So I have an open wireless connection and unprotected.
I hate switching my network provider. Now I need to write it all down, for when I get fed up with comcast and decide to move to another provider.

New Airport Extreme (Jan 2007) with Comcast Cable Network

Im a total NOOB. Please excuse my poor knowledge of Routers and the like.
I really need some advice from the MAC community to steer me in the right direction. I want to give as much information as possible in order for you folks to help me down the right path.
CURRENT SET UP:
(3) Apple Computers in 3 bedrooms. (1) iMac Core2 Duo, (1) iMac Core Duo, (1) eMac G4. All have built in wireless cards from Apple.
Broadband Cable Internet from Comcast. Cable comes from wall directly to a Motorolla Surf Board Wireless SBG900. The Wireless Motorolla Cable Modem sits on the floor in the corner of one bedroom. All 3 computers work perfect. Never drop a signal. All very fast connections. No Internet or sharing issues at all. I also decided to add the "Plug in" Airport Express. This has an HP Color Laser Jet Printer pluged into it via USB. All 3 computers print and share seamlessly to it. Set up is a breeze. No issues what so ever with anything.
QUESTIONS:
(1) Should I eveen bother with the New Airport Extreme Base Station or just leave everything as it is?
(2) Is there ANY benefit to adding a Airport Extreme Base Station? I'm I missing out on anything?
Please be honest. Anything wrong with my current setup?
Thanks.

I don't think there's anything wrong at all with what you've done. The bottom line is do YOU find any faults or disadvantages to your set up? As far as the new Extreme, things would just be alot faster (for those 802.11n enabled computers only, though)

Using my 30 inch Cinema display to watch my Comcast Cable?

Just a thought, my monitor is much larger than my tv. Is there such a way to hook my cinema display into my comcast cable/dvr box?
Thanks,

Call Gefen and see if they have that solution. If they don't, then I doubt one exists.

Connecting Cable Internet to Time Capsule

I know this is dumb, but I'm tired! I'm trying to set up Time Capsule using my cable internet. Time Capsule obviously does not have a coaxial cable port, so how do I actually get my internet feed into the Time Capsule? Do I need to keep using the router provided by Comcast and only use Time Capsule as a wireless backup? Thanks!

You don't need to keep Comcast's router, but you do need something that can operate as a cable modem. Depending on the exact details of your Comcast service, something like this device.
If you don't want to go that route, you should put either the Comcast router or the Time Capsule into "bridge mode". You're better off not having two devices both acting as a router.

Comcast Cable High Speed Service-No offered Firewall,Virus protection,etc

IMac G5 Mac OS X (10.3.9)

Hi, garyah and ~Bee!
I'm writing to echo Bee's words of encouragement.
I also have Comcast + a Cisco router. As far as I'm concerned, the router's firewall is extra gravy — OS X's is fine. Enabling this firewall "built-in" to OS X 10.3.9 that ~Bee mentioned is a simple matter: System Preferences »» Sharing »» Firewall »» Start. Mac Help »» type in "firewall" and »» "sharing" will provide you with ~all you want to know. [1]
Beyond this, imo, common-sense resistance to "social engineering" is the best protection — i.e., think before opening an email attachment or launching an .exe file from a potentially dubious source, etc...
Security remains one of the subtle pleasures of Mac ownership. [fingers crossed!]
Warm regards,
Dean
[1] Various "Services" may need to have ports "On" in Sharing — but each port opened to enable network services is unprotected, even with the firewall running. This is good to keep in mind, too.
Hey, ~Bee — what'd'ya mean none of Comcast's perq's are Mac-compatible? Don't Comcast Mail and "The Fan" work for you? </giggle> While this context is handy, have you ever used their "Personal Web Page service?" My son's bugging me to put up a web page, and I'm a true neophyte...

Comcast cable and streaming media

I just got Comcast cable access. Web browsing is super fast and email seems pretty smooth. BUT, I no longer can access internet radio thru iTunes, nor can I view or listen to any streaming media. BIG disappointment right off the bat. I've spoken to one Comcast support person who concluded it must be an Apple problem and told me to call them after checking out my connection and modem. I had Verizon DSL just 3 days before and everything worked beautifully.Network Utility returns a 100% failure when i ping a site most of the time, but then it works fine with 0% loss at other times. I'm going to contact Comcast again and talk to a different person.
Any thoughts??

"BUT, I no longer can access internet radio thru iTunes, nor can I view or listen to any streaming media."
"I had Verizon DSL just 3 days before and everything worked beautifully."
Judging by the above, apparently some settings must have changed when you switched over to Comcast. Check your iTunes preference settings & the preference settings of whatever apps you use to view streaming media.
Another thing you can try is this;
Repair permissions.
Shut off your computer.
Disconnect the cable modem from the power outlet for approximately 3 minutes.
Reconnect the cable modem & turn on the computer.
If none of the above works then recontact Comcast. However, this time ask/demand/be firm to speak w/a tier level 2 or 3 mac tech support. Make sure you get a case#.
Explain the problem to the tech in detail.
The Techs may have you unplug your modem like I explained previously. If they ask you if you already did this always tell them NO.
Sometimes, they may ping your modem. Depends on the situation.
Let them know how long you have been "having problems". Give them a date & remind them again about giving you a case # if they did not give you one in the beginning of the troubleshooting efforts.
This is where your case # comes in. You do not pay for internet cable service that you never receive. Your case # is your only proof. The Tier Level Techs will provide further instructions. They are the only ones who provide case #s. (Very Important if dealing with Comcast - for your personal records, make a note of the date & time of the call, techs name & location. They will only give out their 1st names. This will come in handy if there is a discrepancy in your bill/you did not get your credit.)
Good Luck

Uverse vs comcast cable for working with TC. (Currently have DSL)

Excuse me if this has been covered before.
I have a time capsule, seems to be working fine. I would like to get a faster internet and am trying to decide between Uverse and comcast Hi speed internet. The cable is not in the same room as my office so am considering, setting up a "modem and router in another room where the cable is and then just using the Time capsule for wireless backups.
If i go with uverse, then i could set up the gateway in my office but may want to use their wireless system over the time capsule system
Is that doable? is one product better for this than another?
Thanks so much

Bob, thanks for your prompt and helpful reply. A little more information: We currently have cable internet, with a cable modem supplying internet service to my router. So I want to replace the cable internet source with the Uverse source, and simply plug my router into the RG. Therefore, I want to disable wireless on the RG. My router is a Netgear WN2000 n. Now, to add the second chapter of the story..........
I built our house with a LAN. My router is in the basement, so I don't get good wireless service (except from the neighbors) on the second floor. I want to add something on the LAN that will add to the wireless coverage. Am I looking for a Wireless Access Point? Your reference to "bridge mode" is something I have seen snooping around my local Fry's. If I understand this correctly, I could add a WAP in bridge mode to my existing wireless network, and therefore broaden the coverage.
Do I have this right? If so, how do I configure the WAP? Same SSID? Same channel? Does coverage flow seamlessly from the basement router to the WAP?
Thanks so much for your help. I have seen your excellent advice on other posts, and I was just about to contact you with this second issue when I got your reply.

Phone Adapter for cable internet

I have recently switch to cable internet and phone service through Cableone. I purchased a CM100 modem, but didn't realize that I also needed a phone adapter. What do I need to by now to hook up my phone? Just the PAP2 Phone Adapter or do I need to purchase a router as well? Thanks for any replies...

Either you can go for PAP2 or else you can VOIP router. WRTP54G.
