These will often not only tell you the speed and duplex of your connection but also the cable run length (they send a pulse and time the reflection from the far end). If those measurements look screwy then I think you are just going to have to re-run the cable.
I agree on hard to find. My desktop at home has a it built in to the motherboard BIOS (EP43-DS3R). There used to be more of them around back in the ISA NIC days, the beloved 3C509 had a great little utility suite that booted from a floppy. It's going to be something specific to the NIC model as it is going to read non-standard registers in the Ethernet PHY device, so you are relying on the NIC manufacturer for this unfortunately.mmmmmdonuts21 wrote:Any program in particular that you have in mind? For some reason this software is very hard to come by.

See my earlier post. You have to be very careful with the grounding of the shield otherwise you can get quite large currents and blow things up in the worst case, or have it act like an aerial and add more interference. It's generally not recommended.SomeOtherGeek wrote:I have always heard that having shielded wires (any and all kinds of wire) in a wall were always a way to go. It is a precaution to many things and reasons.
notfred wrote:One other thought, I wonder if you are simply running in to too long a cable. How long is the cable(should be less than 100m/328ft)? What is it rated at (Cat 3, Cat5, Cat5e)? What speed does your HTPC negotiate at (10Mb, 100Mb or 1000Mb)? Note that 1000Mb requires all 4 pairs to be working in Cat 5 or better whilst lower speeds use only one pair in each direction.

When I tried plugging it back into the PC the connection drops like it did before. So bottom line I think something is wrong with one of the pairs, so it looks like I will be replacing the cable in the next few days or so once I get my shinning new CAT6 (should I go CAT6A from monoprice instead?) cable in. Thanks for the help again.
