Same problem here, all was fine until I upgrade to firmware version Archer C2_V1_141117.

I have to power cycle the router to login...

Any solution?

Archer C2 remote web management

Do you have public IP address on WAN port? What are the Remote Management settings on the router?

Hello everybody,


i have the same issue, but I can't figure out how to solve the problem.
When I go to the IP from the Archer C2 I am asked to log in. When I log in it only says HTTP Error 403.
When I use the wrong password, the Archer tells me, that the password was wrong.
Now my biggest problem: You guys said, that this 403 error appeared, because there is already a second session logged in, but if one of my devices shows the 304 error message and I try to log into the Archer from a second device the Archer tells me, that it allowes only one Admin per time to log in. I should try again later. When I wait, until the first session is logged out and then log in again I only see the 403 error message again. Same Problems after plug out and in the Archer.
I think my FW isn't up-to-date, but I have no idea how to update, since I only see 403 error :(


Please help me.


Thank you in advance

Any anti-virus software running on your PC?
Did you try to login the web interface in local nework? What's the web browser? Try to clear browse cache.
C2 is a brand new device? Power it off and back on but it doesn't help?
