===VLAN Support=== ===VLAN Support===
-It was previously believed that Broadcom gigabit models did not support reconfiguring VLAN's but this has been proven to be untrue. However, the VLAN GUI page does not properly configure the nvram variables associated with VLAN's and so you must configure the nvram variables manually. The [[Switched Ports]] page explains how to configure the nvram variables to get your VLAN's functional. The VLAN GUI is fixed in build 15508 and higher.+The VLAN GUI was fixed since build 15508, but may not work for some configurations.

[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

  • 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

  • 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 [1].
  1. Download the trailed build (K2.6_mini_wrt320n.bin), then from the Linksys webgui, reset to defaults.
  2. 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
  3. In the Linksys webgui, go to Upgrade and flash the trailed build, then wait' 5 minutes
  4. 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
  5. 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] 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):

  1. Unplug router
  2. Press and hold the WPS button on the front of the unit.
  3. Plug power back in with button still pressed, hold down button for 10-12 seconds.
  4. 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
