How to connect and configurate Tp5210g-> wrt54g


F

freejazz

Hi, i would want to connect my Tp5210g to my router Linksys
wrt54g with dd-wrt firmware.
I would want to use the cable from Tp5210g to Linksys and then i
would want receive via wifi from Linksys the Internet
network.
I want be able use the lan ports of Linksys as available and
working ports to connect other devices.
Do you know how i need to configurate and connect the cables?
Can i connect ethernet cable from Tp5210g to internet port of Linksys?

There are two kinds of Ethernet cables, straight-thru and
crossover cables.

TX_________straight-thru_________RX
RX TX

The idea is, for Ethernet to work, the TX on one unit, connects
to the RX on the other. Each end is transformer isolated, which is
why electrical ground is unimportant on Ethernet cables. The Ethernet
cable has no shield, no metal shroud on the connector end.

When you connect two computers together, that's when you
need the crossover cable. So in this case, I draw two computers.

RX_________crossover_________RX (Use crossover cable when
TX TX connecting two 100BT computers)

As far as I know, the WAN port is flipped already, so that
modem-router-computer wiring can use straight-thru cables for
everything. The natural order, dictated the best choices for
the position of RX and TX.

The above rules apply to 10/100BT wiring, which uses wires
1,2,3,6 of the eight wires in the cable.

TX_____straight-thru____RX TX___straight-thru____RX
modem RX TX router RX TX computer
(WAN) (LAN)

On GbE (gigabit) Ethernet, the hardware uses all eight wires.
If a four wire cable is used, the hardware has no choice but
to limit operation to 100BT. But if all eight wires are there,
the GbE runs at the gigabit rate to a second GbE device.

One feature that GbE hardware has, is MDI/MDIX automatic wiring.
It doesn't matter whether you use a straight-thru or crossover
cable with a GbE computer, as the GbE chip will figure it out
by negotiation. Very few 100BT components would be able to
automatically switch the TX and RX pairs. Which is why we have
those strange rules about cable usage.

I keep only one crossover cable in the house (blue plastic on
one connector, red plastic on the other connector). I use it when
connecting two ancient (non-GbE) computers together. But I
haven't needed that cable in a long time. All my other Ethernet
cables are straight-thru wiring (pin 1 goes to pin 1 on the
other end etcetera).

Tp5210g <---straight---> Linksys <---straight---> Computer
