Windows 7: Help! - crazy ethernet cable problem!

Hi everyone - I have tried all the suggestions now.. I pinged successfully from one machine to the other and back again using AEM's suggestion. So not the cable - not the card - not the port on the PC???

So I thought.. must be the modem!

Went and bought a new one.. same problem... Have connection to outside world but my computer just won't communicate with the modem and the only solve that Windows 7 offers is to plug my ethernet cable in. I have done all the tests so I am wondering what on earth the problem is???

Does anyone think it may be a virus or something? mmm it is most frustrating!

You said "Have connection to outside world", this means it is going out through the modem.

So you have all the machines hooked up to this modem, and they all have internet accesses. Just cannot connect from one Pc to another, using map drive?

No I can connect one pc to another - no prob there.

By 'Connection to the outstide world' what I meant was that my modem is connected to my ISP (ie the status and ADSL lights are working and my isp shows me as active)
I cannot connect to the internet from my PC.

The LAN light doesnt light up on my modem and all Windows tells me is I need to plug in an ethernet cable (see previous posts on all the tests I have done on that).

I can't work out why the LAN isnt working.

unless i missed it i assume you have a router? if the is the case unplug the router from the modem and plug the problem machine directly into the modem. your isp should have asked you to do this.

Well this narrows it down a fair bit. You already know the ports on your machine work, cos you can cross-cable with it. The cable also work. So then the modem port could be dead. I assume you tried other ports on the mode (is it multiport)?

Can you do ipconfig /all and privde the details?

This is getting more and more bizarre. At this point it sounds like the only device that can't connect to the modem is the W7 machine yet it can connect via cross cable to another computer. Jeez!

You know, it's going to turn out to be something simple and we're all going to smack foreheads and let out a *DUH* when it get fixed... certainly...eventually...hopefully...maybe... ?????

What you're missing here is a router. It's really a much safer and better way to connect computers to the internet anyway. They're also dirt cheap nowadays.

If you can lay your hands on one, it's worth the cost. You may never know what the problem is but if the router gets around it, well that's what's important anyway. Getting internet access back.

Ok so the direct cross-over cabling work, what about connecting the computers to the ports of the modem and try connecting between the machines? Basically using the modem as a hub.

I see two different DLink ADSL2 modems. One with a single ethernet port (DSL-2320B) and one with 4 ports (DSL-2540B). Something tells me he has the single port model.

Hi - I have the 4 port ADSL2 504T Generation II DLINk Modem Router.
How do I connect the two machines and see if one will talk to the other? Will this work if the W7 PC doesnt even think it has an connection to the modem at all?
Someone suggested it could be the network plug (port?) Does anyone know how I can test that.
THis problem is most frustrating as everything seems to work (the network card, the cable, the modem) but they just won't all talk to each other.
(My old MAC is connecting fine.. LAN light on and everything - its VERY weird)
