I have an asus P5KPL/1600 MB and i am currently have 100mps connection i reasently installed a whole new network with a new modem at 1Gbps speed with a router that supports it apparently i am using the standard CAT cable so any way if anyone could suggest away to do this like Router settings or MB bios settings or something any help would be greatly appreciated thank you all in advance.

I just looked at the ASUS website page for the P5KPL-CM motherboard:
http://usa.asus.com/product.aspx?P_ID=6nnVb6RBxd7PhGmt&content=download

It says that motherboard has:

PCIe Gigabit LAN

So, you already have the necessary hardware:
just change the speed.

If you want to add a Gigabit Ethernet adapter
to your PCI slot, then read on ...

It turns out that adding Gigabit Ethernet is relatively easy now,
especially if you still have old PCI slots available.

The following assumes that you have decided on one of
Intel's excellent Gigabit LAN adapters for PCI slots e.g.:

http://www.newegg.com/Product/Product.aspx?Item=N82E16833106121&cm_re=intel_Pro%2f1000-_-33-106-121-_-Product

Install the Gigabit LAN adapter in your PCI slot,
by following the manufacturer's instructions.

You may need to supply device drivers from
the CD-ROM supplied.

In Network Connections, right-click on that connection icon:
then Properties | Configure should bring up a window
with a number of tabs.

Under the Link tab, you should see "Speed and Duplex".

For a Gigabit LAN adapter, the speed should default to 1 Gbps.

PCI is an old standard that still works well for Gigabit Ethernet:
32 bits x 33 MHz = 1,056 Megabits per second (just enough for GbE).

> i am using the standard CAT cable

Also, the cable to insert in your GbE port -- whether on-board
or add-on controller -- needs to be at least CAT-5e or better.

The cable between your modem and your router can be
CAT-5, because that connection is slower.

We like to add a Gigabit switch in between the router
and the workstations: this allows the workstations
to communicate directly with each other through that switch
without needing to use the router.

With this scheme, all workstations are wired directly
to the Gigabit switch, and the only devices connected
directly to the router are the modem and that Gigabit switch.

Then, whenever a workstation needs to access the Internet,
the switch sends packets to the router, which in turn
passes then to the modem, and vice versa.

This setup works beautifully for us:
GbE for local LAN traffic;
12-16 MB/sec. for Internet access.

first, a standard cat cable doesn't help, is it cat5-e or cat 6? you will want cat 6.
second, you need to make sure that the device your connected to also supports gig Ethernet, one end cant have a max of 100 mbps and one be 1 gig. if one is lower than the other, that's what speed it will be.

> MB bios settings

I looked at your motherboard User Manual,
under BIOS | Advanced tab:

The only options there are:

Onboard PCIE GbE LAN: [enabled/disabled]

LAN Option ROM: [enabled/disabled]

Unless you really know what you're doing,
I would stay away from the Option ROM:

speed settings can usually be done
from Control Panel | Network Connections
as described above.

GOOD LUCK!

CAT-5e will work AOK at Gigabit speed over short distances.

CAT-6 is better, of course, and more expensive too

Its all auto - if its not at GBe speeds you dont have the cables or switch to do it etc

Double Check device manager under network connections. Double click on the adapter and check the settings.

Yes but i am not completly sure that my router supports the following 1Gbps because when i put in the Cat 5 cable inside the pc direclty modem>pc it does change to 1gbps but if it goes through the router it does not and i poked around the settings and did change my own Pc's settings to 1 gigabit but still no change as long as it goes through the router perhaps i need faster one but the thing is that on the third pc i have it has wireless internet which goes through the same router and it has the required speed which is indeed faster then whatever i am getting.

Did you save your router's manual? Or can you go to their website and download one? If your router supports 1 Gb, well and good. But many don't, and for even those that do you may need to manually change the port speeds. And another concern would be, if it is a poor quality router, will you really benefit from forcing the change? Or will all the packet timeouts, collisions and retrys negate any boost in speed over 100Mb?
