DLink Dir 815 Dual Band 2.4 ghz not working
« on: February 03, 2018, 06:30:06 AM »

I have a D-Link DIR 815 Dual band router.

5 ghz signal works fine with all devices.
But for 2.4 ghz I have trouble connecting devices. They see the signal, then connect for a few minutes, even if I am close to the router.
I followed several advice or instructions from this post but nothing works.

Hardware version: B1
Firmware version: 2.07

My actual config is
SSID: Custom
802.11 Mode: Mixed mode 802.11 n, 802.11 g and 802.11 b ( I tried others already ) 
Enable channel autoscan: true
Transmission rate: best ( automatic )
Channel width: 20/40 Mhz ( auto )
Security mode: WPA-Personal

I already tweaked this options and trying other values to each one but I have same results

Thank you for help.

  • What region are you located?

Can you configure the router for a factory reset, then go in and set the security mode for the 2.4Ghz radio for OPEN. Don't use any WPA security. Save settings and see if any of your devices can see the SSID name and connect?
