Homeplug networking problems

August 30, 2009 at 00:40:41
Specs: Windows XP SP2
Hi, I am trying to add this PC to the network (plan to use it for CCTV recording) but having problems.
Connects to the Homeplug network (if I pull the RJ45 it says "Cable unplugged") but will only produce an IP address starting 169.
I'm not very bright with networking but I do know that, to be on the network it has to start 168.
I've tried releasing/renewing the address via command prompt (without any success - it releases then when I renew it times out)
Spent four days banging my head against this brick wall.
I'm open to any suggestions (including throw it in the bin now!)
If it helps: NTL 10M cable BB, Linksys router (wired/wireless), 4 Homeplugs, 2 laptops (wireless) & X-Box (wirelss).
All work fine except this one
Thanks for any help

Where is your modem in this setup? It sounds a bit like you have the modem going into one homeplug and then run your router WAN port off a homeplug. Your wireless devices running off the router are ok but when you connect a wired pc to another of your homeplugs, It cannot connect to your LAN and instead takes over your external IP. I would suspect your other devices would still connect to each other but may lose internet when you connect the wired PC.
You should have the modem connected to the WAN port of your router and then connect from one of the router LAN ports to one of your homeplug devices. The wired PC should then obtain it's IP from the router.

As an experiment, put the wired PC close to the router and connect directly from router LAN port to PC. Does it connect to the LAN and get an appropriate IP with internet access?

Thanks for the reply.

The set up is as follows:
Cable modem >> (WAN) Router (LAN) >> Homeplug >> various PC's around the network.

None of the PC's have wireless cards fitted (I removed them some time ago).

No particular PC has to be on for any other to connect to the Internet.

All other PC's have a local IP address.

As I said I'm a bit thick when it comes to networks and what I've found this morning is that the problem PC is lacking a network controller ... still trying to establish what driver I need.

OK. What operating system is the problem PC running?
In Devicemanager do you have any network adapters listed and if so are they shown with a yellow ? mark

If it is missing the driver for the card there are a number of ways you can go about identifying the make/model. Is it a brandname system? Is the network card inbuilt in the motherboard or an add-in card?

OKay: OS is Windows XP Pro SP2

Network card is built in and says its a Realtek RTL8139 (this is under network adapters)
Below that is says Network Controller - this is where the yellow question mark is.

I have downloaded and installed the drivers for the network apapter without any problem. I thought that would resolve the Network Controller issue ... wrong again!.

Checked the Main board which is an MSI board with an Intel chipset - tried various drivers for that without success.

Thanks for your help so far - it is appreciated

Sorry, should also mention that I have tried uninstalling both the controller and the adapter then restarting - found the adapter but not the controller drivers.

I don't think the homeplug will offer an IP address. You have to set a static.
