Limited or no connectivty - 10Base T Full Duplex works

zer0ness · 11-22-2008, 01:13 AM

Hello everyone.

Yesterday I got my modem from ATT and was quite happy that I finally got a decent internet service. I hooked it up to my laptop via ethernet and it worked great. Then I decided I wanted to hook it up to my desktop via ethernet. I turned wireless on and my laptop got great wireless signal. However, my desktop refused to connect to the modem via ethernet.

I tried everything and I got a "limited or no connectivity" with 169.254 address. I tried the VB winsock fix, the MS KB update, and all the other fixes such as power cycling the modem, updating drivers etc. I tried everything and nothing worked! I then came across a post that said to change the connection type under the properties sheet from "Auto negotiation" to "10 Base T Full Duplex"... and to my surprise, it worked!

However, I'm worried that I'm not getting the full speeds that I deserve. When I try 100 Base T full duplex I get the same error! Is there any reason I'm getting this? I'd like to get my full speeds from my ISP... so I'd appreciate a fix on this.

Thanks!

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.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Was it working before on your desktop just with your old ISP?
