Does a Router Store Any Personal Information?
Yes, your router does store information about your computer when you connect to it. However, it does not store information about any network traffic to or from your computer or any personal information on your computer (think about how big a hard drive the router would need to store that much data).

.

Subsequently, one may also ask, does your modem store information?

What your modem does is translate the data that is sent to it so that it can display on your computer. Computer information is stored digitally, however information sent over phone and cable lines are analog waves. So your modem takes the analog waves, changes it to digital and delivers it to your computer.

Also, do WiFi routers have memory? For how long does a router keep my WiFi records? Most inexpensive home routers do not keep wifi or other history information. They don't have enough memory or storage capacity to save any information about past history. Once you disconnect from the router, or restart the router, the information is gone.

Similarly, do cable modems store personal information?

No, in fact your modem (or other access device) has a tiny amount of nonvolatile storage available for its own configuration and an even tinier amount of RAM to run it's operating system and all functions. All your traffic passes through your modem, ONT, etc but it doesn't store any of it.
