    I have the same problem and set up. I just purcahsed a mac book and had comcast install internet service at my home. They supplied me with a RCA DCM425. At first my connection was weak at best, but comcast has corrected that issue. I now have fast internet once I'm connected but I always have trouble connecting. Sometimes when i'm connected it just locks up or loses connection. As far as the lights "able activity" and "PC link" are flashing while the other two remain solid green. Could this be the modems fault? Should I just buy a new one?

Hello Jodu,

Please check the internet settings of the Lan connection in the Mac Book. May be there is IP Address or DNS settings is installed in your Mac Book which are stopping the wireless network services. Please check the IPV4 settings in the Lan or wireless connection properties.

I have Comcast high speed internet, and recently purchased a Linksys model WRT160N V3 wireless broadband router to allow me WiFi access throughout my home. I have a 2008 Apple MacBook (13") that I'm...


I had issues as well until I changed my router I also went with the linksys router and changed out to D-Link wireless router. I understand that who wants to pay the extra for their wireless router. It is not much more to get one of theirs that is already configured for comcasts dynamic IP address's. This is the fast way to fix the issue. However in any case some routers do not work with comcast they should you would think?
Unplug everything and start from scratch. Do not hook anything up at once. Start with the Comcast modem and plug in the R-45 cable into the router first. Then start the computer up again and the router. Now plug in one computer at a time. Wait for it to configure by checking the Internet on the Mac book first. You will need to make sure that the Mac-book is configured and working first. The Mac-book should be WiFi ready and you should be able to log in to it. Comcast is a dynamic IP service it will find the Mac-book give it some time to search for it. Once this is working the internet on the Mac-book then do the rest of them power them on insert the compatible WiFi connectors that will work with your router. Then one by one do them all until they are working.
Worst case scenario would be to either purchase a D-Link router that does work with comcast this is what I have. My phones also started working as well. After doing this I also researched the comcast pages to find the compatible routers that will work for you. Or get their wireless router to finish this project. I know it is not the answer you are looking for but it is what I did to resolve my issue which was a true pain in the buns. Thanks for using FixYa! John

Use safari as it is mac. Go to connection/internet panel and set up connection with whatever connection you have. If comcast is giving you issues force them to make the connection work. Its part of your benifits.

The first thing is that Comcast is Not a DSL connection it is Cable connection. Now first make sure that your computer will be able to go on line when connected directly to the modem. Connect your main computer directly to the comcast modem and check if that goes on line. If not then you will need to contact Comcast and get main computer on line. If it is online then reset your router for 30 seconds. release the reset and wait for 1 minute. Now connect the main computer to the router and comcast modem to the router. open the set up page and Clone the MAC address of the " Main " computer.
power cycle the modem and the router. See if it works.

Cannot connect to the internet


Are you running the setup disc provided by comcast to get your email setup?

If you are , you do not really need that disc as it provides useless and often outdated junk on the disc. You should be able to surf the internet by plugging in your Ethernet Cord into the laptop with no problem.

On the issue of the Comcast user name and password, this was originally used at the original configuration of the modem when it is wallgardened.

You can always call Comcast and have then activate the modem for you. You'll need the Mac address at the bottom of your modem to activate it over the phone.

Online Activation usually requires your customer account number. But since it looks like you do not have this data, you will need to call them directly.

Can't connect to the Internet via router


Well, this is a very generalized problem that others have, so i'll give you some starting tips. If you can connect when you plug your computer directly into the modem, then it sounds like your modem is bonding to your computer. There are a couple ways to fix this. The easiest is to ask your router to clone your MAC addess (not to be confused with a mac computer, a MAC address is a 10 digit code that uniquely identifies your computer on a network). See the attached image to find where it should be. c26d492.jpg
Once you set it to clone your machines mac address, unplug the computer from the modem, and plug in the router. If this doesn't fix it, please comment back and we'll try some other things. If it does, then give a good rating :-)

Hook up wireless interenet


Did you by any chance give you router the mac address on the wireless card? Do you have the comcast version of a netgear wireless router? Any wireless router will do also. Does not have to be netgear or from comcast. You can get online by the network cable right?. Where else are you trying to connect to wirelessly?

My Router is out of warranty how do I troubleshoot it?


Hi, the BEFW11s4 sometimes is just a plug and play router. If your internet is working when your pc is connected to the modem, just do this steps.

1:Lets reset the BEFW11s4. with the power on, push the reset button at the back of the router for 30seconds, unplug the power of the BEFW11s4 for 10 seconds.

2:Disconnect the pc from your Comcast modem. Connect the ethernet cable from your modem to the INTERNET PORT of the BEFW11s4. Connect the pc to the BEFW11s4. NOTE; MAKE SURE THE PHYSICAL CONNECTION IS CORRECT.

3.Open INTERNET EXPLORER. ONLINE OR NOT?

A. IF ONLINE, clear the address field then type 192.168.1.1, if it ask you for a username and password, then we are ok. THE ROUTER IS ALREADY WORKING.

B. IF NOT ONLINE, TURN OFF PC, TURN OFF BEFW11S4, TURN OFF THE COMCAST MODEM. WAIT FOR 3 MINUTES

TURN ON MODEM, WAIT FOR 3 MINUTES, TURN ON BEFW11s4, WAIT FOR 3 MINUTES, TURN ON COMPUTER

IF STILL NOT ONLINE. Open internet explorer, type on the address field 192.168.1.1, username(nothing, as in blank), password(admin), click ok.

It will take you to the Linksys configuration page(Purple and white screen. On the screen you can see tabs

SETUP WIRELESS APPLICATIONS AND GAMING
MAC CLONE

CLICK THE MAC CLONE TAB, then click on Clone or Clone your pc mac, the save settings at the buttom. After this try the internet. If still offline, unplug the power of the BEFW11s4 for 10 seconds, try the internet again. It should be working now.

If still offline, do STEP 3B AGAIN. IT SHOULD BE WORKING ALREADY. IF THIS DOES NOT WORK, you really have to buy a new router.

I have solved this exact problem more than a thousand times. It always work if the router is still ok.


Good Luck
