Broadcom's BCM5357 is a Single-chip 2.4G entry-level IEEE 802.11n retail router solution. This wireless LAN (WLAN) router system-on-a-chip (SoC) solution has enhanced features, industry-leading performance and best-in-class power consumption. With this new Intensi-fi® XLR SoC solution, Wi-Fi® system OEMs can leverage unparalleled silicon integration to reduce the overall cost while still maintaining adequate multiple-input and multiple-output (MIMO) performance for streaming HD video throughout the home. Broadcom has optimized this new 802.11n router solution with its Accelerange™ technology for enhanced throughput and range performance along with advanced features that minimize power consumption for 'green' functionality modes.
1: Integrated IEEE 802.11n radio, media access controller (MAC), baseband, CPU, memory controller and 5-port Fast Ethernet switch
2: Integrated 2.4 GHz power amplifier that has been proved in the field on shipping production platforms
3: USB 2.0 host port for storage and print server applications
4: Application and service support through NAND Flash and I2S
5: PCM interface support utilizing Broadcom's proven VoIP software stack
I have successfully flash RT-N10U with DD-wrt as following:
dd-wrt - v24 preSP2[beta] Build16994:
dd-wrt firmware name: dd-wrt.v24-16994_NEWD-2_K2.6_mini_RT-N10U.trx
firmware release date: 2011/05/26
download location: Pleases search dd-wrt's router database with "n10u"
I was able to flash DD-WRT directly form original Asus's firmware's webgui.
Asus RT-N10U should be the successor of WL-520gU. It is low price, with 802.11n 150Mbps, double the ROM and RAM size (520gU is 4MB ROM & 16MB RAM). The antenn is 5dBi, much longer and fatter than N16.
Due to BCM5357 is single chip SoC contain all the functions with 300MHz process speed, it could face performance suffering if many people and services are running simultaneously.
1: cheap. I bought it for less than 35$US
2: It has 8MB rom and 32MB RAM. Able to flash 8MB or less 3rd party firmware to expand its ability, such as VPN, BT, QoS, USB & NAS, & VLAN, etc.
3: one USB 2.0 port.
4: Asus original firmware provides 4 set of SSID, to simulate 4 routers.
5: Asus's firmware restoration is easy to use.
6: It has power button at the back.
Because the price is cheap, I won't complain too much. If I really have to complain something, then I would say the CPU's heatsink is small, and glued on the chip, which is hard to tear it off and change to a bigger one. Secand, LAN is not giga port. :p
Let's go stright to the well flashed N10U with DD-WRT's system info and board photos. Photos are 800 pixels.

I tried to upgrade its memory to 64Mb, I did set sdram_init from 0x0419 to 0x0c19/0x0c29/0x0113 along with (or without) manual_boot_nv=1, but it was always reporting 32Mb.
What is odd is that after setting sdram_ncdl to 0x0000, it does not get recalculated after reboot, remaining 0, therefore I believe it doesn't use these nvram settings.
I did manage to (stable) 'clkfreq' overclock it to:
354,177,88 / 373,186,93 / 400,200,100 but it gets quite hot even after radiator replacement. I would recommend 354,177,88 with stock radiator to have it running for years.
