I have a netgear WGR614 v8 and a Brother HL-2270DW wireless printer. Yesterday I flashed the router with DD-WRT firmware. now my printer will not connect. printer error page says "Connection : Failed (Error : TS-07) The machine cannot detect a WLAN access point/router that has WPS or AOSS enabled. In the "SES / AOSS / EZ-SETUP / WPS Button" section of my router control panel I enabled "turning off radio". I disabled the router firewall. I connected the printer directly to the router with a network cable. There is no evidence of any communication between the printer and router that I can find. Any help or suggestions would be greatly appreciated.

It sounds like your printer is trying to locate an access point using WPS while DD-WRT seems not to be configured to support WPS (or may not offer WPS at all, depending on the version used) and the "WPS" button is used to turn off/on the radio interface of the device in your configuration.
As WPS has known security weaknesses, it should not be used, although the DD-WRT implementation seems to address some of the concerns.
You should enter the SSID, the authentication method (WPA2-PSK presumably) and the secret key into the printer's configuration to connect it to your wireless network.
