Hi,I have comcast triple-play and today I have to reset my wireless router because I forget the administrator password and the guy that setup it for me just, gone. The problem is now I can't connected to the wireless and when I try to configure the router it ask me for IP, mask, something like "IP static resolution" i think, but also, when I connect the the cable directly to the computer it appears with limited conectivity, please help me :S I don't know what to do.

I've had nothing but headaches with netgear units, dump it and get an Airlink or Linksys. They've been pretty much plug and play with comcast for me. Spent a whole day trying to get a netgear unit to work, returned it and set up a Linksys in twenty minutes flat.

Yeah, I know that is a piece of trash, but it was working "I don't know how", and of course my roommates are mad :| all because I reset the router to erase the password, but now the F thing is not working + if I connect a computer directly to the modem I have limit connectivity, and looks like the dcph is not working, I've looking for this in some forums and apparently it takes a while to obtain a ip address from comcast, can somebody confirm that?

I believe they are using fixed IP. But if you setup your PC with DHCP, you should be able to get the IP automatically. The thing is, you have to use the same MAC number to get the connection. The one comcast registered when you first got connect to comcast.

If you don't have the same PC, you have to call comcast to change your registered MAC number to the PC's MAC that you are currently try to connect to comcast.

Once you get connected with one PC, write down the MAC number of the NIC of this PC, also write down the IP address, DNS servers, set netgear router to use this MAC to connect (otherwise camcast will not accept the connection). And according to my experience, you better use fixed DNS IPs in netgear setup. I had problem before without using fixed IPs as the DNSs.

Good luck!

Thanks for the information. A Comcast Rep. came out to my house last night, found out that some type of security setting was incorrect. He changed it and now things seem to be working fine. I have a Linksys router not being used that I will keep as a backup just in case.

i just grabbed the laptop that the comcast guy used to connect (i asked him if he was installing anything and he said no. of course there is this "DeskTop Doctor" in the task area and a program group on my taskbar now). anyway i used ipconfig /all on the laptop he used to test connection to the internet during install. (make sure they use your computer to do this, use one you do not care about polluting with their crap).

jot down the physical address under the network device you are using. in the netgear basic settings screen you do not need to enter anything in the account name or domain name fields. but under 'Router MAC Address' select 'Use this MAC ADDRESS' and enter the mac address you jotted down.

make sure it is in the form XX:XX:XX:XX:XX: using colons and not dashes. click apply and off you go.

i used the wgt624v3 to do this

I've got the same problem myself and just got COMCAST triple play- about a week ago. Used FIX IP before. With comcast and its DHCP- sam setting didnt work with my netgear. Use solution of copying MAC Address to router and it works. Thanks a lot and hope this lasts. - Art

I am using outlook 2007 with Business Contact Manager and Vista Home Premium on a brand new Dell Desktop with Comcasts Triple Play. I use their Modem and my own Netgear WPN 824 Version 1. I have to use Internet explorer to read my comcast emails and have to use yahoo to send and receive emails.

find out what they are first and they configure a new POP3 email profile in your outlook client to pull the mail.

That's exactly what you're talking about here. Kudos for the solution. ;-)

Normally you can just unplug the cable box and wait a few minutes for it to flush out the MAC address of whatever was plugged into it. On these triple play boxes, they have a battery so you can use the phone when the power goes out. To flush out the settings and get an IP address to your router, just hold the reset button on the back of the cable unit for 15 seconds.

The router should be configured for a dynamic IP address. This means that the DHCP for the WAN (wide area network) will be given its IP address from comcast. This LAN portion of the router also should be set to have the DHCP on. Most routers ask you to enter a starting address and then ask how many computers can connect. For example a common starting address is 192.168.1.100 If you specify that 20 computers can connect the addresses 192.168.100 thru 192.168.119 will be assigned to computers connected through the wired/wireless network. Your default address to get into the router from your browser is http://192.168.1.1 Please check the netgear website for the username and password settings.

I spent 30 minutes on the phone/chat with Comcast and they kept telling me to call Netgear...they couldn't help with with a non-Comcast router! I tried the solutions listed here and it worked.

Thank you.

To repeat: "jot down the physical address under the network device you are using. in the netgear basic settings screen you do not need to enter anything in the account name or domain name fields. but under 'Router MAC Address' select 'Use this MAC ADDRESS' and enter the mac address you jotted down.

make sure it is in the form XX:XX:XX:XX:XX: using colons and not dashes. click apply and off you go."

Yes. It still works in 2011...but remember to clear out your settings in the comcast cable modem box (reset for 15 seconds) THEN turn on the Netgear box, and you should be good to go.

Hello,
On Saturday, June 18th I had Comcast Triple Plan installed in my home after switching from AT&T U-Verse. Cable TV seems to be working well but I have had to unplug the router and reset the modem 6 times already because my wireless internet keeps going down. With AT&T this never happened and now I'm wondering if I did the right thing by switching to Comcast. Has anyone has this problem lately? What was the fix? A Comcast Rep is due back at my house today and I really want to get this resolved before I go crazy!
