How to remove a damaged Wired Connection

Hello all. I hope you can help.
My terminal command skills are limited as a retired end user of Ubuntu
(since 05.04).

My Settings/Network shows two Wired entries (because my ADSL service
was poor so my ISP gave me a wireless router that works) but my browser
will not connect if the router is switched on first.

The lower Wired entry for the eth0 DSL router shows "Cable unplugged"
because it was replaced by the eth1 wireless router.
Settings/Network/Options for the eth0 Wired entry shows "Error Editing
connection: Did not find a connection with UUID '(null)'"
because I did "delete" but it still appears. I cannot find a way to
remove this entry in Ubuntu users guide.

The upper Wired entry is working (TIAllAccess wireless eth1)
When I click on Menu bar/Edit Connections it shows only one Ethernet
router (TIAllAccess wireless eth1).
Then I click on Menu bar/Edit Connections/Edit TIAllAccess and it shows
the MAC details of the router (eth1).
After I click on Menu bar/Connection Information it shows details of
the router (eth1).

Please tell me how to remove the second Wired Connection. 
Maybe that will allow my browsers to connect to eth1 (the TIAllAccess
wireless) when it is already running; it does not switch off and on
again easily.

Maybe the Syslog snippets below will help? (that I found when I scanned
there for some details)
