Internet Service Provider and Modem Configurations

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

Router and Wired Configurations
Some things to try: - Log into the routers web page at Use IE, Opera or FF to manage the router. Be sure to log into the Admin account on the router.

Wireless Configurations

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.

PC 3rd Party Security Software Configurations

PC Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8, 9, 10 or 11, set compatibility mode and test again. (For older generation routers.)
Disable any security browser Add-ons like No Script and Ad-Block or configure them to allow All Pages when connected to the router.
Clear all browser caches.
Be sure to log into the Admin account on the router.
Try turning off these features in Chrome:
Top right corner, little bars for options > Settings > Settings (on left) > Show advanced settings.
Uncheck these:
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Predict network actions to improve page load performance
Enable phishing and malware protection

mydlink.com Supported Browsers
Internet Explorer 7 or higher (32-bit) - Add mydlink.com to the "Compatibility View" exceptions list.
Firefox 12 or higher
Chrome 20 or higher
Safari 6 or higher (Mac OS only)

Not all router features and options are the same so users may not see the same features when troubleshooting. Review the appropriate features and options available for your model router.

 Does D-Link Fix Issues Posted by Members in this Forum? (http://forums.dlink.com/index.php?topic=58108.0)
 We are volunteer help for DLink and here to help out with set up and problems that are posted by users here in the forums. If we can not resolve those issues here or if there are problems with anything beyond our capabilities here in the forums, we ask the users please contact phone D-Link directly for continued help and information. Problems with HW/FW and documentation fall under this reasoning as we do not have the ability to effect any changes. As for D-Link support, if they don't know what customers needs as desires are then it's kind of hard for them to make improvements to there products with out someone helping them out and telling them.  Yes, of course please feel free to post and talk about it here, however there is little or no review by any official D-Link support or engineering personnel here in the forums. It's the users responsibility to help notify D-Link support of un-resolved problems and concerns they have, that we can't fix here in the forums.
Please phone contact your regional D-Link support office for further help and information as well. D-Link also offers email-based support, but we find the live phone support more responsive.
