Title: Speeds drop to less than half after a day until Release/Renew or Reboot
Post by: DoubleChi on December 31, 2015, 12:41:16 PM
I get 90mbps solid normally but after a day or 2 it will drop to 30 until I either reboot the router or login and release/renew through the DLINK UI.

Is there a fix for this? Its extremely frustrating...

Care to try the beta? Mines doing well with it.

Either do a factory reset and manually reload v1.08, factory reset then set up from scratch and test again. Do the same thing for v1.09 if you decide to try it.
