About this question
So I'm a noob here and have been doing some research on why my internet (cable modem) locks up about once or twice a week ever since installing a Netgear N900 router a few months ago. After asking around a bit someone recommended I look at my router logs. When I did that I noticed quite a bunch of DoS attacks on router of mine, which may or may not be real, malicious attacks. Below is a snippet of my logs over the last 2 days.
After doing a quick google search on some of the IP's it looks like there are some Facebook and Dropbox IPs in the list. Many of the others seem to be located in Germany, UK, Canada, etc. Not sure what they are or if they are harmful, but I'm beginning to believe that the frequency of these "attacks" is what is causing my modem to lock up. Does anyone know if these are harmful attacks? How can I resolve these types of things from locking up my modem? There is a setting in the router to allow DoS but I'm extremely hesitant to do that, especially if someone is indeed trying to get on my network. FWIW I have about 30 wired and wireless devices on my network (couple of laptops, smartphones, tablets, IP cameras, Sonos speakers, Amazon Echo's, Nest products, other smart home products, etc.). I'm really just trying to figure out why my modem keeps locking up ever since purchasing this new router. Thinking these DoS attacks on router might be the culprit. Any help would be greatly appreciated!
