I have a home-built 333 Mhz system which USED to work fine until yesterday when it failed to connect to the internet. It is one of three (3) systems on a peer-to-peer Fast Ethernet network, communicating with the internet over a DSL modem and Bay Networks (Nortel) Instant Internet II100 Router. The router uses DHCP for both internet and home network traffic, assigning IPs to each system on the net.
The system that failed is my better half's. I have:
1. Checked the cabling, hub, and router.
2. Checked the network card.
3. Run Microsofts net diag (reported network OK).
4. Hooked up my laptop to the network through the problem system's RJ45 jack - worked OK.
5. Checked to be sure I can access the other machines on the net through network neighborhood and Windows Explorer - can, no problem.
6. Installed a different network card, same results, so I reinstalled the original Linksys card.
7. Ran the Linksys diagnostics - failed the Ping test.
8. Reinstalled Windows98se - no change.
9. Checked, rechecked, ininstalled & reinstalled TCP/IP and NetBEUI a dozen times.
10. Tried Microsoft's Internet Connection Sharing - no dice.
11 Matched the network vitals to those on another, working machine - the same, but no help.
The problem system doesn't seem to display the correct IP when I run winipcfg - it displays a different IP, one not on the home network (i.e., displays 169.254.174.124 instead of 192.168.1.1x, like the others; it USED to display the correct IP: 192.168.1.103). However, I can browse the network, get files and save files to other machines on the network, etc. (through NetBEUI, I suppose, not TCP/IP). I just cannot get on the internet. If you think you can help, I have images of the Network Configuration screens for TCP/IP, for winipcfg, etc.
Suggestions, other than buying a new comouter?
