Windows 10: Unstable internet connection on my PC

I have that unstable internet only on the computer. I got the message that “couldn't detect proxy settings”. Please point me in the right direction to fix this issue

Unstable internet Connection

For the last couple years i have had a very unstable internet connect. Goes out randomly for 20 to 30 minutes or couple hours or until i reset my cable modem(which is about 10 years old) and router. However, i have contacted my neighbors and when i dont have internet they do. I have also contacted my ISP about it when i lost it and they reported no problems in my area. Is this whole bad internet connect thing caused by my old old Cable Modem??



I was going to order THIS tonight.

 

Internet Connection Broken/Unstable

The internet keeps dropping every now and then, becomes unresponsive and then starts working again.
Long download speeds are broken and not continuous. Is it Windows 10?



I've added a screenshot of the internet graph, it shouldn't be that way should it?

 

Unstable/ Unpredictable Internet Connection On Network Bridge


Hi
I have a server that I has a shared drive I would like to access on my PC. I have my server and my PC connected to the same router by Ethernet, but this router does not have internet access. My PC is also connected to a router with internet access via a WiFi adapter.
In order to access the shared drive on my server and access the internet at the same time, I had to bridge the Ethernet connection to my router without internet, and the WiFi connection to the router with internet. However, occasionally I will not be able to access the internet through any program, and my web browser will display errors such as "dns_probe_finished_no_internet".
I am unsure what causes this problem, but it usually happens when I am accessing or transferring large amounts of data on the network drive.
Any help is appreciated,
Thanks.
