Router disconnecting from internet DIR-600L

[anvesh]

Hi,
I have D-Link DIR-600L router. From several days, it is disconnecting from Internet frequently at random interval. Sometimes it gets disconnected in 10 mins sometimes after 1 hour. After short time of 1 to 2 mins, it gets connected again.
1.When I connect PC to modem directly with Ethernet, it works fine
2. Tried resetting router several times but it is not working
3. Firmware is up to date
4. Tried resetting password

For Example, see this log

What is the internal IP range allotted by your router?Does this ip "10.240.254.113/114" appears in your list of connected devices?Log indicates a network attack resulting in disruption of connection.Rare to see such attacks against a home user,usually these are directed against business users.

IP Range is 192.168.0.100 to 192.168.0.199. Even after changing password of admin, I am experiencing such attacks.

Use mac filtering & put only your devices in the whitelist & see if it helps.
