Weird E1200 v1 (Ver.1.0.03 (Build 4)) Issue

Hey guys, im having a weird issue with this router.

For some reason i dont know, after i enter the GUI via web as admin and try to change an option in single port forwarding i.e ( when i try to change the ftp option to none (ninguno in spanish)) the access to the GUI of the router becomes unavailable( firefox display the error message when you cant reach a website).

The weird stuff is that if make any other change, the router works fine without any problem, just that particular option makes the router to lose admin acces. BTW  i still got internet access when i have the problem, and to solve this issue ( to make the GUI available again) i have to reset the router.

I already updatead firmware, and i run out of ideas....

Instead of doing Single Port forwarding in the Firefox, try to do it in a different browser like Internet Explorer, Google Chrome or any other.. You can even try to open up the ports through Port Range Forwarding and can check the connectivity status..
