Title: No wifi all of the sudden
Post by: jofalfa on September 30, 2015, 02:10:27 PM

Hello-

I tried looking through other posts and FAQ before posting but couldn't find a solution.  I have a DIR-615 N 300 that I've had for 3 years.  It has never been a problem until yesterday.  There is still an internet connection to my desktop PC but my laptop and Roku which I use through wifi all the time has suddenly stopped working.  Nothing happened that I know of and my router still has all the lights on as they normally do.  I tried resetting it numerous times and unplugged and replugged wires from the router and modem to no avail.  When I look for a wifi connection on my laptop my username isn't even an option on the list where it's been for years.  I'm puzzled and would appreciate any help you could give me. 

Jo

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

Try manually re-loading current FW. Do a factory reset before and after sending the FW file.

• Ensure the default (dlink) SSID name is changed. 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 or try 20Mhz only.
• 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 interference's?
• 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.

You'll have to forgive me but I am not tech savvy at all and have no idea what you're asking.  Not sure what I should do first.
