DoS attacks/WLAN access denial showing up. Not sure what to do.

I'm getting a lot of these entries in th Logs, is it normal?  While this is happening, on the home screen it keeps saying I'm not connected to the internet.  I have the Nighthawk X4 R7500v2 firmware v1.0.0.26.

Re: DoS attacks/WLAN access denial showing up. Not sure what to do.

There’s nothing in that listing which I would be particularly concerned about, the frequency is not high so really should not be affecting your network, there could however be a more significant issue for your ISP network. Have you contacted your ISP to see if there are any current problems? What kind of service do you have e.g. cable or DSL and what is the brand and model number of your modem?

If you contact your ISP to see if this is a general issue you could also ask that they change your Public IP address, though they may advise you that this is uncessary.

Okay, if it happens again, I'll call up my ISP.  Thanks for the help.

Please feel free to post back here also. While I don’t think that your internet connectivity should be affected by what is listed in the log, if this continues it may be worthy of further investigation, but the ISP situation may be very relevant in that case.
