Hub Networking Clitch

[wayne]

We are using a windows2000 computer at work with a hub to
print on 2 large format printers. We recently got dsl for
our internet. There are 3 computers hooked up to the dsl
router. The two without the printerhub are straight to the
router, the computer with the hub is hooked to the router
thru the hub. When I set the hub computer to work with
dhcp I lost the printer ip configuration. Now I cannot get
the printers to work. I am new to networking and
understand alittle bit about ip addresses, but need help
finding a solution. Any help would be GREATLY aprreciated.
Thanks

if possible - connect all to the dsl router which probably has an
integrated 4 port switch.

if you cannot do that, on such a small network, turn off dhcp and assign
network info manually.

I've often seen dhcp not work thru hubs.

Is the one workstation connected directly to the printers for printer
sharing via parallel ports?

Hi Rick,

Thanks for responding. Will dhcp work through a hub?
I may noy have enough ports on my router to support all
the printers and computers. I have other printers on the
parallel ports, they are not shared. I was going to try
to put in another lan card to run the internet
independently and keep the printer hub alone on its own
lan card.

This may be resolvable by experimenting with speed/duplex settings on the
NICs connected to the hub. An alternative would be to try replacing the hub
with a switch. In the end, your dual NIC approach may be the
easiest/cheapest solution. You may be able to route straight through the
dual NIC machine or you may have to use NAT depending on your router's
capability.

Yes,...but is this new "router" giving out addresses compatible with what
you are already running? If not you will either have re-address your
network to be compatible with the "router" or will have to re-configure the
"router" to use what is required by the network. This will still be true
whether you use DHCP or not.

I may noy have enough ports on my router to support all
the printers and computers.

Plug the hub into one of the router ports. Make sure you get good LED lights
when you do. Now the hub ports and the ports on the "router" are all
"one-and-the-same" and it doesn't matter which one you plug machines into.

How are these "network printers" setup? Do they have IP#s? Do you realize
that you can't use DHCP with the printer because the IP# needs to always be
the same? The IP# the printers use must also be compatible with the
"router".

You can pick up a small switch for the price of a good NIC these days.
Uplink the router to the switch and connect everything to the switch.
Less hassle than adding a NIC to a existing machine.

I have set up the internet connection on its own lan
card. The other card that has the printers and hub
attached are still dhcp enabled. How do I disable this
card so I can enter ip addresses manually. I cant find
this option.
Thanks

You need to build this in a more conventional way, you can't keep "sticking
this here" and "sticking that there". You can't have something on its "own
LAN card" because you only have one subnet. All machines should only have
*one* NIC.

You have one LAN, you have one subnet. The Hub, combined with the built in
Switch of the "router", are the logical "center" of the LAN. You will
either use DHCP from the "router" or you won't. Since the Network Printers
can't use DHCP because the IP# must stay the same you are probably better
off disabling DHCP and running static addresses on everything.

The Subnet that the "router" uses on the internal LAN interface and the
subnet that you run on the LAN must be in agreement. The LAN interface of
the "router" typically will be the Default Gateway of the Devices on the
LAN.

Phil,
OK, I was able to get everything going. As I said in the
beginning of this thread, I am NEW to networking. Thanks
for the help, I do appreciate it. Although, I could have
used alittle less attitude, this was frustrating enough
for me.

 

[Rick Chisholm]

what was your solution?

Rick,

We pulled the additional card from the computer. We had
to uninstall the internet Protocal from the LAC
Properties, because the router had enabled DHCP and we
could not remove it. With only the hub and the printers
connected we rebooted the computer, which now allowed us
to change the IP settings. We reasigned the printers ip
settings and now we are going again with the printers.
We still need to work on the router because it is still
hooked up to the other two computers. I will try to
assign a static ip to the other computers so I can get
all three online without using DHCP. Im still fairly
confused, but its beginning to gel. Thanks again for all
the help, I'll scream for help if need be.

the static IPs will probably work out very well for you in the end.

My writing style gets me into trouble sometimes. Don't worry, the emotion
you probably read into it wasn't really there when I wrote it.

Thanks Phil,
Ive been fried abit setting this up, Sorry I took it the
wrong way, I really do apreciate the help. Thanks again.

 

[Phillip Windell]

I should should be apologizing, ...not you. I need to be more careful how I
write.
Let us know how it goes.

 

[Rick Chisholm]

I think as techies - we're all a bit fried.
