Internet Connection Problem!

[r3igninblood91]

Alright I have looked all over the net and I can't find an answer. My friend went on his computer one day and his internet would not connect. He has comcast high speed internet, uses firefox browser and his computer is connected directly to the modem. This is the weird part, his dad's laptop uses the internet through the wireless network they have set up and his dad's internet works just fine. He has called comcast several times to attempt to get an answer and they don't even have an answer. We have tried resetting the modem and rearranging cables & other stuff. What could be the problem?

im no pro like some of these guys but would guess maybe ur modem is not dhcp enabled.try ip config to see if it is.Also some more info would help these guys diagnose the issue.I would repost with details of modem/router model and computer model

Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.




Please give an exact description of your problem symptoms, including the exact text of any error messages.

• If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
• For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
• Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
• If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Type the following commands on separate lines, following each one with the Enter key:

PING 206.190.60.37

PING yahoo.com

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
