The Linksys E2000 is based on the same hardware as the Linksys WRT320N v2.0 with changes to the CFE and a larger NVRAM block. The E2000 is based on the Broadcom 4717 cpu running at 354MHz. It has 8 MB flash and 32 MB SDRAM. The WNICs are provided by the BCM4717 SoC (2.4GHz B, G and N) and a second constituent chip, the BCM4322 (5GHz A and N). The switch is a BCM53115 chip. The E2000 runs 802.11 A, B, G, and Draft N wireless protocols. It provides 4 gigabit LAN ports and 1 WAN port.

|System-On-Chip:||BCM4717 rev 2 (MIPS 74Kc)|
|CPU/Speed||74Kc 354 Mhz|
|Flash size:||8192 KiB|
|Wireless:||1x Broadcom BCM4717 SoC 802.11b/g/n, 1x Broadcom BCM4322 802.11a/n (integrated)|

There is also a serial connection on the PCB inside of the WAN port. Serial port settings are 115000@8N1 with no hardware or software flow control. This has been copied from E3000 toh page; location and designation are same for WRT320N/E2000.
The bootloader on the E2000 contains a tftp server. See http://wiki.openwrt.org/doc/howto/generic.flashing.tftp#bootloader.contains.tftp.server. After powering down the router, plug ethernet cable from your computer to port 1 of your router. The default address of the E2000 is 192.168.1.1, so you need to set up a static route for that ethernet interface on your computer (I usually use 192.168.1.6). You need to use the firmware file named for the router, openwrt-e2000_v1-squashfs.bin. Follow the steps on http://wiki.openwrt.org/doc/howto/generic.flashing.tftp#bootloader.contains.tftp.server to flash the router.
