Title: Periodic WiFi Connectivity Issues (DAP-2553)
Post by: wimpog on June 03, 2013, 10:25:22 AM
Two D-Link DAP-2553 in an ESS config (with 2 other Linksys WAPs) on different channels, v1.27 of firmware in a small office of 15-20 clients. When rebooted work well for a couple of days and then lock up and nobody can connect to, unless you stay connected before the lock-up happens.
Tried changing Beacon and ACK intervals/time-outs, as suggested here:
http://www.helpowl.com/q/D-Link/DAP2553/Technical-Support/frequently-loosing-connection-dap2553/267291 (http://www.helpowl.com/q/D-Link/DAP2553/Technical-Support/frequently-loosing-connection-dap2553/267291) but that didn't help.
Firmware v1.27 was downloaded from: http://tsd.dlink.com.tw/downloads2008.asp (http://tsd.dlink.com.tw/downloads2008.asp)
Hardware: A1
Right now I'm thinking of returning both of them, unless someone has something else to suggest.
Thanks!

Welcome! (http://forums.dlink.com/index.php?topic=41537.0)

Wireless Configurations
Links>Wireless Installation Considerations (http://forums.dlink.com/index.php?topic=48327.0) and Managing Signal Congestion (http://forums.dlink.com/index.php?topic=53228.0)
 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?
[/list]
 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 (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.

 Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
 Try turning off Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition,and Extra Wireless Protection if you have it.

Yes, the issue is still present. I'm going to try dd-wrt.

DD-WRT on the Linksys E2000 at my private place has really made a difference. It has all sorts of issues before (using stock firmware) which Linksys couldn't resolve - not even the simple bug where setting ant NAT port interval wouldn't work. DD-WRT was installed...now it all works :)

Unfortunately there isn't any 3rd party support for these DAPs.

Are these 2 DAPs in the same location or near by or in different locations?
Have you swapped the DAPs with each other as a test?

Any chance you can take one of the DAPs to a different location, like a friend or families place and install and see if the problem follows? Hoping what we can help narrow this down a bit more. Please let me know if you can do this...
