D-Link Wireless Access Points For Business => DAP-2660 => Topic started by: Abdul Hai on April 29, 2019, 03:08:53 AM

Hi,
I've D-Link DAP 2660 2 No's in all our branch offices which are restarting very frequently. This has started from last one month. Can anyone suggest me & what could be the reason.
I have updated the devices with latest firmware(1.15) & done reset to factory settings, but still facing the same issue.
Given static ip address to all devices.
My observation : When ever any user(Windows-10 without latest updates / Android Phone) joins this wifi device then all the users connected to that particular wifi will get disconnected and WIFI SSID will not be displayed for 2-3 min in the wifi list.
Thanks in advance :)
Best Regards,
Abdul Hai

- Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
- What wireless modes are you using?
- 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
- 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
- Channel Width set for Auto 20/40Mhz or try 20Mhz only.
- Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channels) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
- What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
- What wireless devices do you have connected?
- Ensure any devices with WiFi adapter drivers are updated.
- Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
- Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner (http://forums.dlink.com/index.php?topic=48327.0) to find out. How many?
