I'm working on a Win98se peer to peer network with 10 PCs, DSL connection & Cisco 678 router. When I did the initial install everything was up and running just fine. The only shares are printers and ACT database folder. The company buys and sells used furniture and computers. The owner recently hired a tech to build and repair systems. He decided for whatever reason to change the IP addresses. The original working setup had TCP/IP addresses 10.0.0.1 thru 10.0.0.11 with the first being the default for the router and used as gateway. Subnet is 255.255.255.0.

The tech for whatever reason changed the adresses to 192.168.0.254 for the router and gateway. The Pc's which are numbered 192.168.0.1 thru 192.168.0.10 and same subnet. I have no prob with 192.168.0.XXX. works fine on all but 2 of the computers. Is there a problem with having the gateway set to xxx.xxx.xxx.254? Would that limit to 8 addresses? When I go back I'll set the router to a lower IP add. than PCs.

Both computers cansee the local network but won't connect to internet. DNS setup has been gone over a million times and is correct. Router can be pinged. 127.0.0.1 pings too. IE 6 and Winsock config removed and reinstalled. Tried with virus scan and firewall disabled.
Pissed off and lost. Help! Any ideals?

The router should be fine at 192.168.0.254 (you are thinking subnet mask and subnetting) and the subnet mask of 255.255.255.0

If you are having problems with the two computers, but everything else works fine, then concentrate on the two computers. They sound like they are on the proper network and that everything matches between these two computers and the working computers as far as ip addresses/subnet mask and gateway? If the three components are setup and the two non-working computerscan ping the router, then you should be fine.

Ping a site on the internet by ip address (go to another computer and ping www.yahoo.com or some site and see which ip address it reports, then try it on one of the non-working computers).
If you can ping by ip address and get a response, then try ping www.yahoo.com.
If you ping by name and do not get your response, then you have a DNS issue. If can ping both ways, you should be able to browse without problems.

If pinging and external ip address by name and by ip both work and your broswer still fails to work, then try another broswer manufacturer (even temporarily just to confirm that it's IE's settings or something in windows conflicting) try Opera or Netscape on one of the two non-browsing computers.

Don't get mad... you just need to narrow down the possibilities of where the problem is so that you can find the problem.

You should also be able to browse by ip address on your browser if you want to try that before installing another broswer.

Took a deep breath counted to ten. Downloaded full version of ie6, uninstalled and reinstalled again on both pcs. Removed some search engine software, chat and related junk. Cleared out the network settings and started from stratch. One of the 2 systems is now on the net, hate it when I don't know what was sucessful. All the things I tried are now a blur. Anyway still seeking ideals
Thanks to those that respond.
