[edit] WRT320N Information
Linksys WRT320N is supported since build 12956 (2009-09-23), using kernel 2.6. Device forum thread, for more information: Eko's original announcement
[edit] Hardware Specs
- CPU Broadcom BCM4717A (354 MHz)
- corerev: wl0=17
- Flash/RAM: 8MB (serial) / 32MB
- Radio: b/g/n 2.4 GHz OR a/n 5 GHz (Not dual radio)
- Wireless speed: up to 300 Mb/s
- Wireless MIMO config: 2x2:2
- Antenna gain: 1st and 2nd main 1.5 dbi, 3rd antenna: 2.2 dBi
- Ethernet: Broadcom BCM4717A
- Switch: Broadcom BCM53115
- WAN/LAN: 4 / 1 (Gigabit ethernet)
- S/N prefix: CUH0
WARNING: Linksys wired the reset button to the wrong gpio, so hard reset doesn't work, and boot_wait is off by default. In DD-WRT, the reset button works, and boot_wait is enabled. Builds after 13493 must be used for WPS button hard reset support, reference "30-30-30 reset does not work" for more info regarding how to hard reset this unit.
[edit] Installation instructions
- For initial flash, a trailed build (with the model in the file name) is required: 14929 K2.6 mini trailed build
- After initial flash, upgrades can use any non-trailed generic (not nv60k nor nv64k) K2.6 builds from HERE.
- Download the trailed build (K2.6_mini_wrt320n.bin), then from the Linksys webgui, reset to defaults.
- Router default address is 192.168.1.1: Set your pc to a static IP e.g. 192.168.1.6 subnet 255.255.255.0
- In the Linksys webgui, go to Upgrade and flash the trailed build, then wait' 5 minutes
- Open 192.168.1.1 to the DD-WRT GUI, set a user and password, then do a hard reset:
- Unplug the router, push and hold the WPS button on the front
- Plug the router back in, continuing to hold the button for 10-12 seconds, then release
- This should reset to defaults again: access the GUI to set a user and password, then set up DD-WRT
- Switch your PC back to DHCP if needed

[edit] VLAN Support
The VLAN GUI was fixed since build 15508, but may not work for some configurations. For details, see the Switched Ports for manual configuration of the nvram variables.
[edit] Known issues with the WRT320N
[edit] 30-30-30 reset does not work
Linksys wired the reset button to the wrong GPIO, hence a 30-30-30 reset will not work.
In order to perform a hard reset on the WRT320N, follow these steps (using at least build 13493):
- Unplug router
- Press and hold the WPS button on the front of the unit.
- Plug power back in with button still pressed, hold down button for 10-12 seconds.
- Release button after 10-12 seconds. Wait 2 minutes, then access webgui at 192.168.1.1
You can also perform a hard reset by telnet or ssh by entering the following commands into the CLI.
erase nvram && reboot
[edit] Troubleshooting tips
Reference: install post by bbb_forever Router is not getting its WAN and DNS IP addresses from the ISP: -Cycle power on the modem to reset the DHCP lease
If you lose Internet access, but used to have it with the old router, then this may a possible remedy: -Clone the MAC Address of the previously working device e.g.:
- Local computer's MAC address or previous router's WAN MAC address (look on the bottom of the router)
-Worst case, you may have to call the ISP to reset the allowed MAC address
[edit] Some other useful tips

To set the clock speed to 300 MHz, use telnet, SSH, or Admin->Commands to run the following:
nvram set clkfreq=300,150,75 nvram commit reboot
- Note: telnet/ssh user is root, and password is same as the GUI
- In the GUI Commands, run each line separately, or separate the commands with a semicolon.
The reset button and low NVRAM (e.g. for openVPN) issues can be fixed by using buddee's WRT320N conversion to an E2000 forum thread.
