Ethernet connection continually dropping

[luismartin]

My ethernet connection continually drops every few minutes for about half a minute. I've checked that my wifi connection through other devices is fine. So is the ethernet connection I tested with my laptop. I tried both wifi and laptop at the same time my desktop computer running with Linux Mint had no access to the internet neither from Chrome nor Firefox, so it must be something related to my pc, the OS maybe. I also tried switching cables between pc and laptop, getting the same results.

A ping doesn't work either when the connection has dropped. The curious thing in this case is that pings to certain domains seemed to work again before others which didn't work yet until everything was running completely smooth.

Any suggestion to help me sort this out is welcome.

It's sure using a LOT of memory for some reason . .

Please post results for

lspci -nnk | grep -iA2 net

There might be another module(driver) available for your ethernet that might work better

I've done it a few minutes ago. Everything is working fine right now. No connection drop so far. I'll tell you in case it's back again (hope not!).

Thank you very much!

Try it for a few days and if it continues to work, edit your original post in this thread to include SOLVED in the subject
