I have a DIR-635 which has worked OK until recently. However, suddenly my computer is not able to access the internet wirelessly through the router.

Wireless internet works fine on iPads, phones etc. The PC is also able to access internet through the router when connected with a cable. The PC is furthermore able to connect wirelessly with the router, however in Windows there is a message that the router is not connected to the internet. iPads etc can access internet through the router at the same time..

Is the problem on the PC or the router?

Thanks!

Link>Welcome!

• What Hardware version is your router? Look at sticker under the router case.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?

Wireless Configurations

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. 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 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, so you might want to try TPIK only or Auto TPIK and AES.
• 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 to find out. How many? Use v3, its free.
• If you have any of these options, Try turning OFF or ON Short GI, 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.
