My ISP keeps blaming my modem (and sometimes the router) for the horrible lagging service I get with the Internet. I stopped renting their modem 12/month for the past couple of years because it didn't make sense. I don't have a lot of money (am retired) and their modems were always refurbished junk that they never upgraded.
I have lived at the same location for over 17 years and do not have any other options for internet service. The issues we experience here are intermittent, but persistent. Several times during the week and what seems random times and days, the service will start to lag. Or it goes offline and then pops back online. I notice this because I can't open email or download a simple PDF attachment. I run their speedtest and see download speeds of 1.4 Mbps. An hour later it may be screaming fast (for me that is) at 400 Mbps. And hour after it may drop to 12 and then back up to 300. This doesn't only happen to me, but many in my community. Then there can be 3 solid weeks without any issues.
The ISP insists it is not them and it is the modem and maybe the router. So I am here wondering if there's any validity to this. Do modems go bad? This one was purchased March 2022. The router was purchased in 2019.

Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.Has a factory reset and setup from scratch been performed on the modem and router?

Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

I would power OFF the ISP modem for 1 minute. Factory reset the router and power it off. Power ON the ISP modem and let it sync. Then power ON the router and walk thru the setup wizard again using a wired PC and a web browser.
Press the back reset button for 15 seconds then release.
