Running 20.04 on a Dell 7010 pc. Network connection often drops. I click on a link or web-page and it fails to load. New tabs come up blank. After a few minutes the service resumes. This happens frequently and it is becoming rather boring as it often disconnects during paying for things, for example
I have another drive with Windows 10 on the same pc-doesn't happen there.
Note-this is LAN not WIFI, which is covered in other posts.
I have recently begun to wonder if this is some sort of power-saving option somewhere. Any suggestions, please?
Thank you!

Re: Ethernet connection repeatedly disconnects.
Perhaps I shouldn't comment. I have something similar on a Dell laptop
Just thoughts.
My clues are it sticks/halts in Firefox with a message saying TLS which I gather is SSL certificates. Sometimes the connection seems ok and then the next moment it stalls. I can Ping my router and sometimes an external site will not Ping. Most odd. The computer works 100% on Wi-Fi. I just wonder if there is a hardware fault like a wonky ethernet socket.Broadcom and subsidiaries NetXtreme BCM5755M Gigabit Ethernet PCI Express vendor: Dell driver: tg3 v: 3.137 port: 10c0 bus ID: 09:00.0 chip ID: 14e4:1673 IF: enp9s0 state: down mac: <filter>
Just thoughts.
