Title: Problem with my DIR-615 router
Post by: vincentsiau on December 20, 2014, 07:09:13 AM

Hi, my DIR-615 router is having some problem. When I connect it to my laptop with a LAN cable, it is able to access the internet. But, when I unplug the LAN cable and trying to connect using Wifi, there is no internet access for my laptop. My laptop shows that it is connected to my network but there is no internet access. This also happens on my smartphone. My smartphone is able to connect to the network, but no internet access.

Any solution for me to solve this problem? Or it means that my router has spoiled?

Thanks,
Vincent

Link>Welcome! (http://forums.dlink.com/index.php?topic=48135.0)

• 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?
• Are you wired or wireless connected to the router?
• Has a Factory Reset (http://blog.dlink.com/what-is-a-reset-button-when-should-i-use-it) been performed?
• Was a Factory Reset performed before and after any firmware updates then set up from scratch?

>FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)

• Was the router working before any firmware updates?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
• What ISP Modem service link speeds UP and Down do you have?
• Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values (http://forums.dlink.com/index.php?topic=53008.0)

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) and Good Neighbour Policy (http://forums.dlink.com/index.php?topic=10634.0)

• Ensure the default (dlink) SSID name is changed. Can be anything and not something that's 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?
• 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 interferences?
• 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.
• 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, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
