Netgear Routers vs. ordinary hubs, killed LAN when changed

The PC's in here were originally on an 8-port hub, and setting the (peer to peer, with Win98, many years ago) LAN up was quite simple. It ran like that quite well, but I wanted more than one to be able to access the same 56K connection, and "sharing" seemed badly broken.

So I bought the Netgear part, which includes an integral 56K Modem. And used it ever since, but it had the bad habit of accepting a bad connection and not letting me know, so eventually, I put all individual 56 K modems back into the PCs, and just ignored the Netgear modem part. Just recently, one of the cable companies here finally made a decent rate for cable 'Net access available. Presently, I have both 56 K in here, and cable 'Net in the bedroom (not yet inter-connected).

I figured I'd put the old no-name hub back in use in here and move the router into the BR. No luck in here; my LAN went away. And I can't figure out why. I tried a second (Linksys) hub in here, and same thing . .

Ideas, folks?

 
Is the modem plugged into the router or the hub? The hub has no NAT abilities so the modem needs to plug into the WAN port of the router.
 
The hub is just sitting in the bedroom right now, until I get the PC's back in here talking to each other again, as they were before the router replaced the hub. The single PC in the bedroom only has one NIC, it's the only one now connected to the cable modem, and until Saturday I could unjack the RJ45 plug on the Cat5 from the modem in there, jack in the CAT5 leading into here, and reboot, then that PC would come up on the net with the two in here, and the one in the Living Room. The "front three" all still have individual 56 K modems in them. I cannot recall anything special I had do do with the NIC setups when the combo Modem/Router arrived, the Netgear manual wasn't an extensive one, is long since misplaced, and the controlling software was set aside with an older PC that was retired last year, and at that time I removed the Netgear device from the phone line, and just used it as a hub.

Incidentally, for the most part, I use Windows2000 now, with XP only on the "game box" back there in the bedroom (as a dual boot, with W2K as Primary). Windows2000 and XP both sensed the NICs, the LAN, and practically set themselves up on the network when those OSes were installed (no, not as upgrades to Win98) -- it was a gradual changeover, though (and though I didn't originally say so, the utility PC that I use for file backup, and for a lot of 'Net browsing, is still straight Win98SE -- it's kinda old) .


 
I have a 5-port switch swapped in place of the eight port hubs, that is working for the first two Win2000 PC's, although I now have them requesting passwords from each other that I haven't had previously. Also, the Win98 PC (this one, in fact) doesn't see either of those two through the switch. I'll attach the hub to the switch now, to see if the print servers come on line (for the Win2000 boxes, at least). Why the W2K boxes didn't like the plain hub, I have no idea.

Nor, sad to say, do I recall any more where the password control is located on the W2K setup . .

 
Regular, Hub/Switches are dumb devices that do not dynamically affect any thing in the network.

Giving your description above it is hard to figure out the make up and topology of your network.
Past stories are not as relevant as the exact current configuration.

May be you would like to take a glance at this pages, they were written a while ago. Ignore the prices and the Hardware recommendations, stick to the principles.[/i]

The whole thing should look like this.

If your network is configured correctly, the password thing is related to the way your File Sharing and network protection is set.
