I have used the Buffalo WHR-G300N over 2 years while I will use it for connecting all of my devices to Internet @ home. However, two days ago, I have the issue that the router suddenly disconnected from the Internet -- all of my devices (wired and wireless, Notebook, Mac Mini, iPhone x 2, iPod Touch, iPad, Nexus 7, Windows Phones x 2) cannot connect with the router. I have tried to turn router Off and On -- the internet connection was back to normal for several minutes (sometimes longer, sometimes shorter).
Yesterday night, I had tried to connect the WAN to one of my notebook (nearby the WAN line) and connected to the Internet very well. Therefore, I think there is a problem on my router.
In addition, I have saved a log file from the router and the contents is as:
2014/07/03 23:01:15 FIREWALL 2 connection denied from 10.245.246.29:n/a to 224.0.0.1:n/a (eth0)

I found that there is a strange connection blocked by my router; and the connection from 10.245.246.29 (this is NOT in my subnet nor any devices I owned).
Does anyone have the answer? or got the same question?
