Title: After upgrade to 1.04 cant achieve 300mbps
Post by: felircf on March 28, 2014, 08:10:35 AM
In 1.01 I was able to connect with 300mbps speed. I have a dir-655 also and no problem. Now the max speed is 144Mbps. Is this a fw problem?

  • 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 N or mixed G and N?
  • Channel Width set for Auto 20/40Mhz.
  • 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 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
  • 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 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.

What region are you located? Brazil
Has a Factory Reset been performed? Just the upgrade.
Was a Factory Reset performed before and after any firmware updates then set up from scratch? No

I recommend that you reload FW code again following this process please:
FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)

Do the factory reset before and after sending the FW file. Then set up single mode N, Auto 20/40Mhz, WPA2/AES only and disable HT20/40Mhz Co-existence.

Please use IE or FF for sending the FW file and disable any browser add-ons and 3rd party security SW before sending the FW file.

Ok this solve the problem of the speed! thank you!

I have another problem now. My 655 have a a range a LOT BETTER than this 645, why? Smartbean dont work? and other thing, everytime when I try to use the DLNA the router freeze and need restart.

To be honest, that's the worst dlink product I've ever had.

Please post about your other problems in a new thread please. Please give details of the DIR-655, ie. Rev # and FW version.

We'll help you out there.

The 645 has worked great for me and others...One of the best routers I've had.
