DAP-2590 and DWL-8200 loses WiFi connection w/ iPads
« on: November 06, 2013, 02:06:57 PM »

At our organization we are using 16GB iPad2 for our staff daily logins. Among our site locations we have a mixture of DAP-2590 and DWL-8200 APs mounted throughout the building, with the latest firmware installed.

On a daily basis we receive calls that staff cannot login due to the WiFi being down. The iPad will show that it's connected to our WiFi network, however it cannot get anywhere on the internet.

We have a firewall that sits behind a PoE switch that all the APs connect to. The firewall is then uplinked to a comcast modem that brings everything out.

I've already confirmed that our upstream devices weren't the cause as I was able to hard wire my laptop into a port on the firewall and got out, as well I did on the comcast modem.

The WiFi issue can only be fixed by either a) disconnecting and re-connecting the WiFi network on the iPad and /or b) power cycling the APs.

I'm going to try changing wireless bands to 'g' and changing the channel. From what I can see on inSSIDer, at some of our sites we have other wireless networks in the area that bleed into our environment.

I'd like to test another AP product from a different vendor as well to see if maybe there is some sort of incompatibility with this particular dlink AP and the iPad2

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion
  • Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring 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 on 5Ghz?
  • Channel Width set for Auto 20/40Mhz or try 20Mhz only.
  • Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
  • What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
  • Any 2.4Ghz cordless phones?
  • Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
  • If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
  • Enable WMM Enable Under Advanced/Advanced Wireless.
  • Try setting Medium or Low power output settings and test again Under Advanced/Advanced Wireless.
