I just bought a Buffalo WLI-TX4-G54HP and flashed v24-sp2 voip 14896.
The board seams to be identical to the WHR-HP-G54, so I disassembly it and soldered a RJ-45 WAN jack and a small switch for the AP/router function.
The thing is: when I plug a WAN cable, the link doesn't comes up (I don't see the LED lit on the other device). And inside the GUI dd-wrt interface, doesn't show WAN MAC address (in status I see LAN and WIFI, but no WAN) nor WAN IP address. I wonder: dd-wrt disables the switch WAN port as soon as it recognize its a WLI-TX4-G54HP?
code:
nvram get vlan0ports
1 2 3 4 5*
nvram get vlan1ports
0 5
Any ideas on how to enable the just added WAN port?

Thanks, Eko, for the suggestion.
I crossflashed a WHR-HP-G54 cfe.bin into the WLI-TX4-G54HP. After revert to factory defaults now I see the unit is recognized as a WHR-HP-G54 and therefore has a WAN MAC address (00:16:01:ED:85:ED). Good.
But still doesn't work. The link LED doesn't lit on the remote device, nor the Buffalo gets a WAN IP address.
Any ideas? _________________ If you want support, please read first the announcements and forum rules.

Except for the WAN RJ-45 jack, the sw2 switch, and the LED11 all I can see was already there. What I soldered was the WAN RJ-45 jack and the switch. The RJ-45 is connected to the Delta's LFE8275 (altough there are some resistors labels on the bottom side on both equipments). Now I'm curious because on the HP-G54 the LFE8275 is shown as TRANS5 and I was thinking it was an IC, but makes sense since I don't read a DC voltage on it. Anyways, I measure a 1.2 Ohms between WAN's pins 1&2, and 3&6, as I do on the LAN ports. In fact, I measure resistance as well between TX and RX pins, as I do on the LAN ports. _________________ If you want support, please read first the announcements and forum rules.

Just for comparison, here are the pictures of how someone in Asia did the same thing with another WLI-TX4-G54HP:

So is there any components there or only labels?
Look at top left picture and the top right picture from the Japanese site and you can see what he has added.
Your magnetic coupler (transformer) will not work without those! _________________ Kernel panic: Aiee, killing interrupt handler!

Meanwhile, I want to ask another thing (and don't want to open another thread for a single question):
I changed dd-wrt SSID name to "TestINit". At my Windows PC I see broadcasting as I programmed it at the GUI, but in inSSIDer I see broadcasting as "dd-wrt". Why is that? any way to change it? _________________ If you want support, please read first the announcements and forum rules.

You don't have the resistors and the capacitors on the rear side of the circuit board!
Those are needed, it won't work without them, they are the filter for the center taps of the mag coupler. _________________ Kernel panic: Aiee, killing interrupt handler!

If you look at the rear side of the WHR-HP-G54 board, the only components I don't have are the FIL21 & C240(beneath the magnetic coupler, apparently connected to its 13th PIN) and C243, since on the other board there is not a R148, R149 and R150 either (altough on the asian site seems that they added them as well as R168 & LED11).
Does anyone knows the value of those components, and if they are usually sold at electronics and/or online stores? _________________ If you want support, please read first the announcements and forum rules.

I afraid I bricked my router.
I was trying to flash a custom CFE with the MAC adress changed and the VLAN ports reasigned to workaround the missing WAN port.
Now when I turn the unit on, all the LEDs at the switch and the power LED are solid green, the red LED flashes slowly and the g and AOSS LEDS flash at half the rate or the red one.
Tried the 30/30/30 reset and ground pin12 of the flash memory. No success. My PC doesn't see the LAN link come up. I don't have a JTAG cable. Any ideas? _________________ If you want support, please read first the announcements and forum rules.

Thanks, barryware! the JTAG thing saved my unit.
Now I'm back at the beggining (crossflashed again).
I did it all again, and found if I hex edit the cfe.bin (MAC addresses) doesn't take it via jtag (freezes at 30%), and with WinSCP takes it, but crashes at restart. Why is that?
Note: I still appreciate any help on the hardware mod issue. _________________ If you want support, please read first the announcements and forum rules.
