Title: spontaneious reboots and crashes
Post by: zvadim on March 11, 2015, 07:01:45 AM

I have 2 DAP-2695 one became unreliable and started freezing up or crashing under load.  Now the 2nd one is following suit with random frequent reboots.  Reset to factory defaults, but didnt help.  Powered via AC brick or via same brick & POE injector, no change.  Load about ~50 users.  Am I just expecting too much from this AP?

• What Hardware version is your DAP? Look at the sticker under DAP.
• Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the modems web page under status.
• What region are you located?

• 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?
• Channel Width set for Auto 20/40Mhz
• 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.
• 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 InSSIDer (http://www.techspot.com/downloads/5936-inssider.html) to find out. How many? Use v3, its free.

Thanks for the quick reply Furry,

I am running latest publicly available fw 1.11-rc044, located in the US.
I have primary SSID XXXWiFi on both 2.4 & 5Ghz, using WPA2/AES/external RADIUS. 
Secondary SSID XXXGuest on both frequencies using WPA2/AES/password.
Have 4-5 DLink access points throughout the building on a separate VLAN.  Two DAP-2690s, and an older DWL-3200.
They all sit on same VLAN and have same SSIDs, users roam between them. 
Channel selection is on auto, and they mostly avoid overlap.
Connected devices are a mix of laptops & phones.

Any chance you can take one of the DAPs and move it to a more isolated area or maybe even test at home for a day or two?
