i can give you a hint. you haybe have 2 routers with identical ip's in your network. or more serious a trojan horse trying to modify your router. start_apply.htm is a file which can only be found on the original asus firmware and on asus routers.

Primarly you should try to totally clear web browser cache. That problem was exist often on my previously dd-wrt router (WNR3500Lv2). Currently I have Atheros based device and this problem is rather absent.

thanks, is there any way to see where the request or attempt came from? like IP? to see if its a local problem or a attempt from outside the local network?

does the ddwrt firmware have any function to protect against attacks from the internet? that are not options in the GUI

i often see

daemon.err httpd[1397]: [httpd] : Request Error Code 401: Authorization required. Wrong username and/or password!

i read people say its normal but not sure why

thanks

I have no idea why all successful WebGUI logins are recorded as authentication errors.

You will find the following SYSLOG entries for every SUCCESSFUL WebGUI login.
The first line will be normal, and second line will be highlighted in RED.
Code:
Jul 24 13:21:46 dd-wrt daemon.info httpd[3257]: [httpd] : Authentication fail
Jul 24 13:21:46 dd-wrt daemon.err httpd[3257]: [httpd] : Request Error Code 401: Authorization required. Wrong username and/or password!


You will find the following for UNSUCCESSFUL WebGUI logins.
Both lines will be highlighted in RED.
Code:
Jul 24 13:21:25 dd-wrt daemon.info httpd[3257]: [httpd] : httpd login failure for xxx.xxx.xxx.xxx
Jul 24 13:21:37 dd-wrt daemon.err httpd[3257]: [httpd] : Request Error Code 401: Authorization required. Wrong username and/or password!


As for the HTTP 404 errors.

Do you have a mobile device with an app that is still trying to possibly connect to the ASUS router's OEM firmware?

TedCheeze those are normal messages, to appear in syslog when you log in...its been discussed many times, it is the normal browser/router behaviour...and there is nothing bad..
If you have unauthorised WEBGUI attempts, there will be either MAC address or IP showing in this type of messages...if those attempts count 5 those will be blocked for a period of time...
and period of time will extend on more attempts...

tgvrfcedx about start_apply.htm BS explained what is the reason for those...and i cannot be more helpful...indeed Razz Embarassed

there are many treads to search and read in order to gain information and do your own research before ring the bell...at least that is what i do...lots of info in DDWRT forum, or google... ask google kernel-panic 69 DDWRT and you will see all his posts...so adding DDWRT to your search yields the correct results..
