Network help

Post by **Francious70** » Tue Oct 14, 2008 7:09 am

Ok guys, normally I can figure this kinda stuff out, but I'm stumped on this.

Ok, what I'm doing is adding another computer to our network here at work and I can't get it to see the other computers on the network. I've got three routers: A, B, and C. All my computers are on router A which recieves it's internet from router B which also has a network printer attached to it. The computer on Router C can connect to the internet and print on the printer, but can't see the computers on router A, and the computers on router A can't see the new computer on router C. How do I make them see each other?

Hmm...they are routers and not switches? the DSL router should be doing all the DHCP leases...

Yep, you should only need one router and two switches. Otherwise you will be sharing a shared IP... NAT x 2 = eewwwww.

By placing machines "behind" multiple different routers, you're inherently blocking Microsoft's broadcast-based NetBIOS communication, etc. Also, you won't be able to access the shares on computers on router C from router A unless you start doing some port forwarding junk.

If your routers have the option, set them to bridge mode. They will cease to be routers and act to bridge the two network segments that were once separate.

Forgive me for being vague, but I'm not a professional with networking.

Router A is a Regular Belkin wireless Router.

Router B is a ADSL Router from the phone company

Router C is a Linksys router with 4-Port Switch

So if Router A was a switch, leave everything the same and it'll work?

Need to turn off DHCP on Router A and Router C...knowing the model numbers of the routers would help to set them up.

If both Router A and Router C were switches, you'd be golden (or if they have the option, set both to bridge mode).

OK, tried turning DHCP off on both A & C, didn't work.

So my best plan of action would be to either replace router A with a switch, or just buy an 8-port switch so I can have all my connections on one switch rather than 2 different ones. Which would you do?

Buy one switch and ditch the routers (A and C).

Word. That's what I wanted to do in the first place, but nobody around here has an 8 port for sale. Weird.

Router B really is a router though, isn't it? Not just a DSL modem?

Post by **Francious70** » Tue Oct 14, 2008 1:52 pm

Correct. It's a Comtrend ADSL2+ Router.

Thank you for your help guys!
