cannot log into router interface after creating a wired bridge and other issues

[unholymachine]

Hello,

I followed the instructions posted on the dd-wrt wiki here  https://www.dd-wrt.com/wiki/index.php/Wireless_Access_Point which are identical to the ones posted in the sticky forum thread on these forums here http://forums.buffalotech.com/index.php?topic=15202.0 . I am able to connect to the internet from ONE computer. All of the rest of the devices connected via ethernet or via WiFi cannot connect. My tablet for example gets stuck on "obtaining IP address" and then automatically disassociates after a while. Also, I am unable to connect to the router's webUI.  If someone could please explain to me what is going on I would greatly appreciate it.

Thanks
