This post will show what the router Asus WL500GP v 1 can be capable of.
1º hack - cpu, usb, network Ic's cooler with little heat links, and a 50x50x10 cooler.
2º hack - internal usb to join a hard 320G d2.5 disk with 2.0 usb to sata adaptor
3º hack - dual antenna wifi hack
4º hack - wifi power and sensitive increase +35/40DB!
5º hack - ram from 32m to 128M
6º hack - over clock from 264mhz to 300mhz
Hardware hacks you must see hight quality pictures with all hacks: http://www.vslinux.net/openwrt/asushacks/
little heat links hack:
I buy some graphic cooler mod, and he have it.
buy some 50x50x10 or bigger cooler at 12v to don't listen the noise.
Internal usb hack:
The usb ic's have 4 ports but only 2 have out, so two inside.
scsi 0:0:0:0: Direct-Access ST932042 3AS PQ: 0 ANSI: 0
sd 0:0:0:0: Attached scsi generic sg0 type 0
sd 0:0:0:0: [sda] 625142448 512-byte logical blocks: (320 GB/298 GiB)
sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Mode Sense: 03 00 00 00
sd 0:0:0:0: [sda] Assuming drive cache: write through
usb-storage: device scan complete
In power you must add a capacitor of like 10v/12v with 1000uf to 5v circuit the handle the hdd power pic.
With hdd the tension drops to 4.7v and must be like 5.10, so this may cause usb problems, so a 5v 3.5/4 amperes is required do add a hdd.
to maintain the hdd on use "sdparm --command=start /dev/sda" without this usb hdd goes to usb sleep.
Add it to crontabs to run itch five minutes.
dual antenna hack
you must by a wifi antenna with sma connector and a panel sma female connector with cable.
Connect it to ground and to c70 capacitor in wifi module.
wifi power and sensitive hack:
change the capacitor position's inside the wifi mini pci module
c94 to c21
c93 to c20
ram hack to 128MB
when solder job is done active the 128M
nvram set sdram_init=0x0011
nvram set sdram_config=0x0062
nvram set sdram_ncdl=0x0000

I used Samsung M470L6524DU0-CB3 PC2700 SO-DIMM: it has Samsung K4H511638D-UCB3 chips
and a 33ohms resistor in r43 to active the U4 chip line.
This Ic's can be used 64 ram ic's:
* Hynix HYMD532646CP6J-D43 PC3200 DIMM: it has Hynix HY5DU121622CTP-D43 chips
* Samsung M470L6524BT0-CB3 PC2700 SO-DIMM: it has Samsung K4H511638B-TCB3 chips
* Samsung M470L6524DU0-CB3 PC2700 SO-DIMM: it has Samsung K4H511638D-UCB3 chips
* Transcend TS32MSD64V3M PC2700 SO-DIMM: it has Elpida D5116AFTA-5B-E chips
Cpu over clock hack
cpu hack to activate the 300mhz
nvram set clkfreq=300,150

tested in Backfire (10.03.1-rc1, r22556)
now in Backfire (10.03.1-rc2, r22752)
only detects 100mb of ram because nvram var was write incorrectly the 0x0000 was write 0 (bad) then originate a random write of sdram_ncdl var.
To solve this you must go to CFE boot in router safe mode by press reset and them type ctrl+c to allow you to typing characters.
CFE>nvram set sdram_ncdl=0x0000
CFE>nvram commit
CFE>reboot
That's all for now folks
