Try setting channel 1, 6 11 or 13 on the 855: http://prntscr.com/8rdz7m , http://prntscr.com/8rdyvc
Disable WISH and WPS on the 855 router: http://prntscr.com/8re1a1 , http://prntscr.com/8re2or
Disable WPA security as a quick test on the 855. Then scan again on the 505. Can it see the SSID then?
http://prntscr.com/8re3cy , Did the scan again on the Dlink Dir 505 and YES my wifi network came up http://prntscr.com/8re4nb
Reenable WPA and try WPA2/AES Only. http://prntscr.com/8re5ua , http://prntscr.com/8re60t
YESSSSSSSSSSSSSSSSS finally! God bless you!!! Thank you very much. Could not have done this without you.
But I need to ask you : what is the best option when using Dir 505 as Repeater. To set its name the same as my wifi network (Use the same Wi-Fi Network Name for the Extended Network )or to put another name (Give your Extended Wi-Fi network a name.)?
Once again thank you and best regards to you
