The Graveyard - Products No Longer Supported => Routers / COVR => DIR-655 => Topic started by: david1012 on July 05, 2013, 06:31:03 PM

I have been having an off and on connection problem with certain wireless devices to my DIR-655 rev B 2.07NA. Wired seems to work all the time. Certain wireless devices, particularly Windows 7 machines, are sometimes not able to connect to the wireless network, which is set up as WPA2, AES. I noticed that I am usually able to connect to the guest network, which I set up as Auto, TKIP or AES. I changed my main wireless to Auto, TKIP or AES and the problem seems to have gone away.
Does this make sense?
Am I sacrificing anything, particularly security-wise, by going this route?
Thanks,
David

- 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 (http://en.wikipedia.org/wiki/Wireless_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 TPIK and AES.
- What wireless devices do you have connected?
- Any cordless house phones?
- Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
- If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
