Title: D-link DSL-2740R Problem
Post by: Blackchest on August 11, 2013, 08:01:38 AM

Hi to all.

I have a problem with the wifi on my router.
It suddenly stopped to be seen by any device in my house.
The wifi signal is green, and in the settings it says that it's on, but i cannot see the signal either with pc or smarthphones..

Any guess about this problem?

Thanks all!

• What Hardware version is your modem? Look at sticker under modem.

• Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers.
• 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 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.
• Enable WMM Enable (http://forums.dlink.com/index.php?topic=50738.0) Under Advanced/Advanced Wireless.
• Try setting Medium or Low power output settings and test again Under Advanced/Advanced Wireless.
