No and to be honest I don't know what a switch is I'm making this up as I go.

This is a switch...It's essentially a box you can add to extend your network.

http://www.amazon.co.uk/Netgear-8-Port-Ethernet-Unmanaged-Switch/dp/B000087H94

Intel e7200 @ 4.0GHz (4.32GHz SuperPi(e)) Lapped
Asus P5E-VM (Vdroop pencil modded)
4Gb Patriot Pc6400 4-4-4-12
250Gb Samsung Spinpoint
Sapphire ATI 3870/Akasa Vortexx Neo
Enermax 600 Watt PSU
Ubuntu/Win XP
All in a Thermaltake Handbag...
Or flying @ 4.21GHz in the Stacker.
 
Try some MM Super Pi(e) here!

Edit: could be that the DHCP server in the router is not responding quickly enough for the cards, if there is no dhcp address, gateway etc.


I would go for the auto-negotiation setting as Dave suggested, but I would drop it to fixed 10Mps half duplex, and if that works try full duplex, then 100 half, etc.


If duplex fails, it is usually a badly made cable. Is it a home-made cable, or a bought one?

The common errors are pairs in wrong sequence, but even that will usually work with 10m half duplex.Can you set the router's speed?

Correct wiring sequence is 1+2, 3+6, 4+5, 7+8

Just patched in socket number 76 on our new cat6 network

I have no idea how to make a wire I didn't think you could Also its working now so I'm assuming I did something though I don't know what and why it would effect just the realteks on two different computers I have no idea. Could it have something to do with dual booting??

It is not unknown for new drivers to install new firmware on NICs, but on-board ones are usually updated with the BIOS.
Could be that the driver update changed something in the DHCP request it sent to the router which caused the router to get confused.

Having said that, my wife's PC fails to get an address from my D-link router every now and then, if she reboots, or I restart the network it works.
Only her computer, and only now and then (oh, and it runs Linux).

DHCP works by sending out a broadcast request for an address, if it does not receive a reply in a certain amount of time, it times out and uses a random 169.254.xxx.xxx address.

If it succeeds in getting an address, it is allocated it for a fixed period, (called a lease), usually a day or two, could be that the card tried to renew its lease, but the router could not identify it properly and refused.
Resetting the router may have cleared the leases.

Thinking about it, IP V6 seems to be updated quite frequently on NIC drivers, could be that.

The router / nic combination is definetely the smoking gun as it connects OK straight into the cable box on it's own.
Also makes me think the patch cable is OK too.
Have to agree with Wiley though that IPv6 causes all sorts of hassles and it's bugger all use ATM, so if it's there bin it.
It's also worth trying the 10mbps speed throttle to see if that helps, but 10mbps is pretty useless these days.
As you're on cable your internet may well be faster than that

I have loads of 5 port switches and cables here from the old ISP business.
More than willing to post one to you, should only cost a couple of quid.
They are D-Link though but they were rock solid with anything we chucked at them.
