for testing you NIC
you can use the command

sudo /sbin/ethtool eth0

or through root

/sbin/ethtool eth0

for internet speed most of the cases for ISPs DSL service they provide modem device
which has its own configuration and web interface, through which you can check downlink and uplink.

dmesg | grep <keyword>
For <keyword>, try things like the vendor name, model #, or just the possible device names.

If you plug in a flash drive, just run dmesg. The last 10 lines or so will tell you all about the flash device, and what device file it was assigned to.

I use bwmonitor to measure bandwidth. You may need to install it.
