Hey all, I currently have a d-link DIR-615E3 with the latest dd-wrt firmware (v24 from 2010-12-13). Everything seems to be ok when I boot up the router - with factory settings and unsecured wireless, I have an internet connection. When I enter the GUI, create a router username/password, everything is still fine. Then, when I create a wireless security password (WPA2 personal) I lose internet connection, and the only way to get it back is to do a hard reset of the router. This also happens if I change any setting within the ddwrt interface, not just the wireless settings. Anyone have any ideas as to why this is happening? (I also have a linksys WRT54GL with ddwrt with absolutely no problems) My cable modem is a motorola surfboard SB5101U, ISP is comcast cable, running windows 7. Thanks in advance!
