Intermittent wireless Internet drops

Model: C3000

Firmware: V2.02.08

OS: OSX 10.11.6

 

I'm having an increasingly technically issue where my wireless connection drops and all my connected devices are not able to connect to the Internet.  First, all the modem/wireless lights remain green and I stay connected to the network however when I disconnect from wifi and attempt to reconnect I'm prompted to enter my wifi password and it comes back incorrect.  The only way to resolve the issue is to manually restart the router and everything is fine.  I've changed the wireless settings to manually connect to the best wireless channel and I've disabled Access Control to ensure there's no devices being blocked. It's getting frustrating as this issue is happening my frequently. It used to be every 2-3 days now its several times a day.  

 

Please help!

 

Edit:

 

I've pulled the event logs and I'm seeing DoS attack? How can I stop this?

    Hello itsmejustin25

     

    In you router go to Advanced-Setup-Wan Setup and make sure disable Port Scan and Dos Protection is unchecked see if this will stop the DOS attacks and see if this the cause of the disconnects.

      Hi Darren

       

      I unchecked the box. Hopefully this resolved this issue.

       

      Thanks
