Unable to acquire network address

[eponymous1212]

Hi,

New to cable broadband. Want to network 2 computers via (hardwire) router.

Set up on one computer works fine.

Experience "Unable to acquire network address ... ltd/no connectivity etc" with the other.

Repair connection seems to work/refresh DNS etc but then 404 when attempt internet connection

Poss problem with DHCP??

Tried ipconfig ... no joy

The settings for the healthy computer are:

autoconfig ip address: [Removed ISP IP]
default gateway: [Removed ISP IP]

Would an option be to manually configure the problem computer based on the healthy configuration?

If so, what would that configuration be, please?

Of course, an easier suggestion would be even more welcome!

Many thanks,
Eponymous1212

I've moved your thread to "Networking".

"Website Discussion" is for discussing the Cable Forum site itself.


The IP you posted was your actual ISP issued IP address, the address your cable modem gets (as such I've removed it for your security).


The PCs' IPs should each be a local IP address assigned by the router - e.g. 192.168.1.2 for one & 192.168.1.3 for the other.


What are the network settings of both PCs?

Matt - Thanks for this

Here is outcome of network diagnostic - forgive me if this is not info intended.

Healthy PC:

default outlook express mail - not configured
default outlook express news - not configured
ie web prox - not configured

network modems [internal modems show-cable modem not picked up]/adaptors/clients passed

Problem PC:

default outlook express mail - failed
default outlook express news - not configured
ie web prox - not configured

network modems [none]/adaptors/clients passed

Hope this helps. If not, please direct me to the specific settings you require

Many thanks,

i actually recommend static IP adresses, my network has been alot better with them and its also quicker for when you areconnecting too!

No problem.

Need the Internet Protocol (TCP/IP) settings for each PC's network connection.

(Connection > Properties > Internet Protocol (TCP/IP) > General)

Are they set to obtain an IP automatically, or do they have an IP manually specified?

The same for DNS.


It's easier to have them all on auto, & just let the router dish them out, although as Callumpy said you can set static ones if you want (so long as they're in the right range for the router).


What make/model router is it?

How have you got everything connected?

Cable Modem > Router > PC1
> PC2

?


Is the router set to obtain an IP automatically?


Is its DHCP server enabled so that it can then dish out IPs to the client PCs?

[eponymous1212]

Matt and Callumpy - Thanks

I agree static would be the most reliable solution ... question is how to identify static IP for router - Newlink 5/8 port 10/100 Mbps Fast Ethernet Switch?

Settings - same for both:

IP/DNS auto
DHCP server enabled
Everything connected Cable Modem > Router > PC1 > PC2
Router fully auto [no manual settings]

Once again, many thanks for your help.

You've just identified your own problem, you've got a switch not a router.

You need a router to connect multiple PC's to VM broadband service, a switch will not do this.

Yes but he has a modem so it shouldnt really matter

... but the Modem hasn't (and never has done) got any NAT/Firewall/IP Masquerading capabilities which means it WON'T work

So use the NAT/Firewall/IP capabilities on the Switch, if that has any

[Graham M]

very unlikely, otherwise it wouldn't be called a switch, not in the domestic market anyway.

err yes it does. the modem gives straight ISP ip's. the router would just have that and then passes local ips to the other pcs

again a SWITCH/HUB doesnt have anything on it to configure other then say a cisco unit. but dont think you'll have 1 of those.

Epony you would need a router to make it work properly.

Calllum, on the domestic market Switches are layer 2 devices, routers are layer 3.

Just for referenece MAC addresses are layer 2, IP adresses are layer 3.

The only traffic management facilities that a switch has is to only send out traffic on the port that is connected to the device with the MAC address that the traffic is intended for.

If you've no idea what i'm talking about, go to google and read up on the OSI model.

And maybe stop giving advice in an area that you obviously know nothing about? Callumpy, better start reading and studying for let's say 2-3 years first, then come back and post advices in this forum?
