looking for netgear WN2500RP schematic

[gripa]

Hello everyone,

I am looking for a schematic of the netgear WN2500RP repeater.

best regards

[stj]

it probably doesnt exist.
the datasheets for the chips may have example circuits though.

I found a schematic for the WNR200v3 so maybe it exists somewhere. I have already created a few subcircuits myself. Unfortunately, I can't identify a component that has broken (marking F42A 1K (1K crosswise)) . But that probably belongs in a different thread.

Furthermore, I have not yet found a data sheet for the broadcom bcm5358ub0kfbg chip.

Anyway, thanks for the answer

So here are the subcircuits that I created myself. Without guarantee. Among other things, Q3 is broken but so far I have not found out what kind of component it is (marking F42A 1K). Maybe someone here can help me.

Hi,

a guy told me the component Q3 is the AO6604 mosfet by A&O.

So I soldered the component in. There is now 1.2 V at the output (pins 4+6). Unfortunately, the extender is still not working correctly. The diodes light up as follows (all continuous):

D909, WPS: off
D904, 903, 902, 901, LAN ports: green
D910, connection to WLAN device: green
D916, Link Rate 5 GHz: red
D907, Link Rate 5 GHz: off
D915, Link Rate 2.4 GHz: red
D905, Link Rate 2.4 GHz: orange+green
D906, Power: orange

A button reset does not change anything.

So the troubleshooting goes into the next round.

(updated schematic attached)

Have you connected a serial console ? It should be J41 on your picture

[gripa]

No, I haven't done that yet, but I will. What exactly can I do with it then? I have little experience with the serial interface/debugging.

[rogfanther]

You can see if the firmware is running. That would confirm the circuit part is correct, and maybe show some messages of corrupt firmware. Or the thing may be stopping at the bootloader due to said firmware corruption. From the console it is possible ( not always, but many times ) to reflash firmware in this case.

Ok thx. I have connected my PL2303 TTL USB adapter (GND, Rx, Tx) but I have not seen any messages. Neither with screen, nor with putty or minicom. I also tried with different baud rates and with Rx and Tx swapped at one end ;/

So there's probably something else wrong and/or Q3 is a different component, although the 1.2 V output voltage makes sense in my opinion.

Maybe JTAG level will give me some information? I could give it a try
