Dell Eithernet connection problems
« on: June 22, 2018, 02:24:17 PM »
Machine:  Dell Vostro 400
This computer has always given me trouble with it's eithernet.  It's hard to get it to connect to my router.  And or routers.  My first router/modem is what the ISP provided me, the second one is the ASUS I bought to go between the computers and the Modem.

I never messed around with the IP settings.  All my other computers have no trouble connecting to either routers.  But this machine has always been buggy.  Sometimes I got to disconnect and wait a minute or two and then try reconnecting and it will connect.  I got sick of it, so I decided to add in a D-link eithernet card.  I thought if I just had a different one in the machine then maybe things would be better.  Wrong!  I have the latest Ubuntu 18.04 Live running, It sees the two eithernet cards but and it can't seem to connect.  It gives me a message that says:  "Connectionfailed Activation of network connetion failed"  by the way they don't have inxi installed out of the box.  Since I have no internet connection I'll need to boot into my linux mint install in order to give you the following information.

For some reason my current Linux Mint 18.3 xfce install finds the new card just fine and works right away!

I'm curious now if Linux Mint 18.3 Live DVD can make use of the new card or not.

Linux Mint 18.3 Live Finds both networking cards but the connection fails.

Tried to disable LAN Controller in the Bios.

Tried bypassing the Asus router and went directly to ISP router.  No change.

I found this thread:  You are not allowed to view links. Register or Login  I would really like the live versions of Linux to work with it.  Otherwise it is not a complete replacement.  Appears to have a Realtek driver thing.  That's probably my problem!

A few variables here! In the posted spec card-2 is up and working, is that in the live or the installed? You say disabling the motherboard port did not set card-2 to card-1 and then work fine? I would have expected that to work.? You could manually define things and get it going, but temporary for a live boot. The install is likely handling some renaming or alias's correctly that the live boot is not configured to figure out...and you find no message for needed firmwares?

I tried disabling the onboard Ethernet.  That didn't help.  The card would just keep trying and trying and trying to connect.  But it couldn't do it for some reason. (Under a live environment)

I took the card back to the store.  I bought another one that is a slightly different model.  I hope it works.  It seems too be.  The whole purpose of putting the card in the computer is to get rid of the headache that the old port was causing me.
