Thank you Cameron but no cheers! Using the command /sbin/ifconfig-a on the first Terminal did produce the eth0 and lo and also wlan0. When I type in the dmesg |tail-100 ....I get bash command not found! So maybe I am not typing this command correctly.
I opened a second Terminal plug in an adapter, wait several minutes type dmesg | tail-100 ...I get again command not found. I then type /sbin/ifconfig-a ...this time I get the following
bash: /sbin/ifconfig-a: No such file or directory. I am at the root level when I am giving these commands.
It really seems that Centos does not see the adapter.
Thank you for you help. If you have any more suggestions, I would certainly try them out.
Thank you
Don

My instructions were for the command line.
Please open a terminal.
At the command prompt, type:
/sbin/ifconfig -a
Note what inferaces are shown; probably "lo" and "eth0".
Type the command:
dmesg | tail -100
Leave it on the screen for reference.
Open a second terminal.
Plug in a USB adapter and wait a few seconds.
Type the command:
dmesg | tail -100
Is there new stuff at the bottom of the output?
Type the command:
/sbin/ifconfig -a
Are there any new ethernet interfaces shown?
Repeat with each USB adapter until one or both of dmesg and ifconfig show new
stuff (ideally both).
When ifconfig shown a new interface you can try to configure it with
whatever setup tools your desktop interface offers.
Anyway, please try the command line based experiments recited above and
report.
Cheers,
