If your computer is already connected when this happens, it will remain connected but will not be in the lease table until the next time it tries to renew.You can disable this by enabling "Use NVRAM for client lease DB" on the Services page. You can clear the password in NVRAM by executing the following commands: nvram set http_passwd= nvram commit After that you will be able to access the Web interface of your router without using a password. This problem affects Broadcom routers like Linksys WRT54Gx, Buffalo WHR-G54S, Asus WL-500 and others (Some with dual partitions revert to factory firmware, ex: Linksys EA8500).
To test this, give your computer a static IP address of 192.168.1.x where x is between 2 and 254. There are a lot of variables in answering this question and we don't have articles to cover all the different situations.
But, for now, search the wiki and the forums for more information, just to verify that it's truly bricked. Verify that the computer is on the same subnet as the router. Verify that the computer is set to dynamically receive its address if it's not statically set to 192.168.1.x.
If you still don't know, search elsewhere on the internet or ask on the forums. Supported Devices Not supported list is here: Known incompatible devices In short, the TP-LINK TL-WR740N is the cheapest compatible wireless router, available for around $20 , as of April 2015.

It's always recommended that you reset to default settings before and after the flash.
If your computer's IP address is 192.168.0.50, you may not be able to access the interface.
DD-WRT firmware default settings (sometimes called factory defaults) are stored in NVRAM. Flashing with TFTP must not be seen as the standard procedure for flashing: only use it when specifically told to do so (for example in the specific instructions for flashing your brand or type of device).
