What custom firmware works with Asus WL-520g? (Note this is not 520gU, 520gC, etc.)

I failed to flash it with Tomato ( - the admin UI does not accept the file, and when trying to tftp the file as adviced for 520gU all I get is this:

Transfering file tomato-ND.trx to server in octet mode...
Error occurred during the file transfer (Error code = 0):
Error in SendPacket() call.

I just saved the router form rather unsuccessful flash to DD-WRT (after few hours the router fell into coma), and I'd like to keep it as a backup should the new one die or whatever. (Unfortunately the stock firmware does not support WOL.)

The Micro version of DD-WRT is alleged to work OK? – Linker3000 Jan 3 '11 at 21:35
I've tested both of them, but there seem to be a problem of CPU load locking at 100%. After a while of playing with web-UI the router ceases to respond. – Jaroslav Záruba Jan 5 '11 at 11:50

OpenWRT can be stripped down to run. You will have minimal memory and space. You may be able to add network disk storage.

Thanks BillThor, but that'd require to learn how to build/compile this stuff, wouldn't it? – Jaroslav Záruba Jan 5 '11 at 10:42
@Jaroslav Unfortunately it would. The documentation indicates your router has extremely limited resources. – BillThor Jan 6 '11 at 3:27
