LAN disappeared after switching from Cable to DSL

LAST EDITED ON Jan-13-02 AT 08:45 PM (GMT)

I HAVE A D-Link DI-704 CABLE/DSL ROUTER - 4 PORT. WE WERE USING CABLE MODEM AND I CONFIGURED ROUTER AND HAD 3 COMPUTERS NETWORKED AND SOMETIMES ADDED A LAPTOP TO THE NETWORK. All worked fine with the cable modem. We just switched to Bellsouth DSL and I had trouble with the router after reconfiguring from cable to PPPoE, but finally found I needed a firmware upgrade; once upgraded, we were connected to Internet but the local network disappeared.

PC1 runs WinME and usually can see the 2 PCs on the network but gets an error message when trying to access PC2 (windows cannot find the computer or sharename, make sure you typed it correctly, etc). PC1 can ping both PC1 and PC2. PC2 runs Win98se and usually cannot find the network and can only ping itself. I discovered that whoever boots up 2nd seems to be the PC that can see both PCs on network but can't access the other or it's printer. Both have TCP/IP configured exactly the same and both have NetBEUI also installed as well as file & printer sharing. I feel like the problem is on PC2 but can't figure it out. We only use the network for printer sharing but would like to have it operational.
Any help or suggestions would be appreciated.

Please provide the information at Start, Settings, Control Panel, Network, Configuration and Identification for both computers. Larry

PC1: Martys850 PC2: Jeff

Both were setup this way (orig. config)in network config. After I made the original post, I noticed that after both PCs were up and running, whichever PC booted up 2nd could see both PCs in network but couldnít access the other. The PC to boot up 1st could not find the network.

Orig. configuration:
Client for Microsoft Networks
Dial-up Adapter
Network fast Ethernet adapter (NIC100 v2)
Network Telesystems PPPoE Adapter
NetBEUI-> Dial-up Adapter
NetBEUI-> Network fast Ethernet adapter (NIC100 v2)
NetBEUI-> Network Telesystems PPPoE Adapter
TCP-IP-> Dial-up Adapter
TCP-IP-> Network fast Ethernet adapter (NIC100 v2)
TCP-IP-> Network Telesystems PPPoE Adapter
File and Printer Sharing for Microsoft Networks


TCP/IP settings for NIC and for PPPoE adapters:
IP: obtain automatically
Wins: disable
Gateway: 192.168.0.100 (the IP I used in router config as opposed to 192.168.0.1)
DNS: 2 DNS IPs from Bellsouth
***********

Another point is that the router config. is using the MAC address of Martys850 in there; I needed to get the MAC address out for old PC we used for cable modem so I tried to restore the router MAC, but then we were unable to access the Internet at all. I thought it would grab the dsl modem adapter address when I cloned the MAC, but it didn't. So it took the MAC of this PC. Shouldn't matter I wouldn't think.

The router should be doing the PPPoE function, if it can. The PPPoE adapters on both PCs should be removed. Cloning the MAC address shouldn't make a difference. You should be able to get the cable MODEM to marry itself to the routerís MAC address by power-cycling it several times. After turning on the power wait until it just initiates and then turn it off. The procedure is more an art than a science and may take some perseverance. Larry

Thank you for your responses. The router is set for PPPoE function -- I reset it after we got off Cable. I just thought that the old MAC address on there might be affecting the network so I tried to "restore" and that's when I had problems getting connected at all so I paniced and cloned it, which picked up PC1's MAC address.
The PPPoE adapter was automatically installed when we set up the DSL connection going stright thru each PC to test them. I suppose we don't need those unless we ever had to use a straight connection without the router. Do you think this is affecting the "network"?

Yes.

Ok, I have removed the PPPoE adapter from both PCs; I also changed the TCP/IP properties on both Ethernet adapters to:
IP: obtain auto
WINS: DHCP
gateway: blank
DNS:blank
We still have no network:
PC1/martys850 can see both PCs and can ping Jeff but cannot access it
PC2/Jeff cannot see the network and cannot ping PC1/martys850
Both PCs are connected to the Internet but just are not networking -- no LAN.

Hi Larry. I really appreciate all of your help so far. I am beginning to believe we have either network "ghosts" or or an extremely unstable system here. Probably both.
I have done nothing different since I last wrote--other than read your 2 links and decide I had met all the criteria and done everything by the book.

yesterday:
PC1/Martys850 could see the 2 PCs and could suddenly print to the printer on Jeff.
PC2/Jeff could not see any network and could not print to Martys printer.

But today is a new day and Jeff has been up all day; once I got home and booted up Marys850:
PC2/Jeff: could see entire network, could access Martys850 and print to that printer, BUT cannot ping Martys850 IP;
PC2/Martys850: There's nothing in the entire network on this PC --- no "Workgroup", but Martys850 can ping Jeff, can find it in a search and can print to that printer.

I have no idea what will or won't work tomorrow. Should I keep the WINS tab in TCP/IP properties set to use DHCP? should I add a gateway IP to that tab? DO you know why we are experiencing such bizarre behavior? Any suggestions to keep the network working even though Martys850 can't see "workgroup" and Jeff can't ping Martys Ip but both can access the other????

There's another BIG problem:
1-the sound has been messed up on both Jeff and the laptop/PC3 (only hooked up to network once), both of which run Win98se. The laptop has NO sound at all and 1 device, Microsoft Kernel GS wavetable synthesizer, isn't operating properly but nothing works when trying to upgrade driver. Apparently there are no drivers on the CD that came with the laptop and NEC provides no help any more.
2-Jeff has the Windows sound at bootup and has internet sound, but cannot play CDs in either the ce-rw or the cd-rom; in addition, several games we paid for that run on Real Network will no longer work.......error message says we need directx8 which we downloaded and installed but the games say we have directx 0.0.......again, everything worked fine on cable modem and these problems showed up after hooking up to DSL. All devices in Device manager show they are fine.

That's a lot for this time--thanks!!!

Mine is set that way (I guess by default; never paid any attention to it) and I have no network (or sound) problems with any of the five (sometimes more) computers on my network.

>but cannot play CDs in either the ce-rw or the cd-rom

Check the audio cable going from the CD drive to the audio card. Volume control?

I donít see how switching cable service would affect the sound capabilities of two computers behind a router.

We are trying to troubleshoot too much at one time.

I would remove and reinstall everything network on your most troublesome computer. Larry
