Router Disconnecting Inexplicably
Recently my (NETGEAR) router just started disconnecting on its own. After a few minutes, it reconnects.
I know it's the router, and not the ISP/cable modem. I have owned my own modem and separate router for years, and when the ISP (Comcast) disconnects, I am still able to access my router's web admin address (192.168.1.1) and see that the ISP is disconnected. With this shutdown, the router's web interface can not be accessed.
Other info: I recently (about 6 months ago) returned to connecting my own machine via Ethernet cable rather than WiFi, whereas all other devices connect wirelessly. Not that this should matter.
I also had installed PRTG network monitoring software after Comcast said I was nearing my bandwidth limit (never happended before) and they coincidently said they would charge high dollar fees for small overages. I uninstalled it when this started happening, but it continues to happen.
The family thinks that malware is in a computer affecting the router, or in the router itself. I don't see how the router firmware could be altered, but I suppose it's possible a device might affect the router (?)
Has anyone seen this problem?
How do I go about tracing the problem?
I should note that I will be getting a new machine on Monday, a desktop this time (I have not lifted my laptop off its cooling platform in at least 5 years). The net reviews seem to circle on Acer Aspire as a good desktop in the $500-1000 range for 2021, good for web dev application work and less-than-intense video streaming. My 9-year old ASUS G74SX has served well and will get a gold watch with retirement. Since I will be transferring the system, I don't suppose I can hope to see if the new machine will stop the router from disconnecting.
