I recently got a refurbished Thinkpad T430s and installed Ubuntu Mate 16.04.3 LTS. One of my customizations was to install conky and download a .conkyrc that gives me a running performance monitor -- cpu, RAM, HDD and network.
This is great, except that the network section gives a skull-and-bones icon and reported "No network." I know I need to edit the .conkyrc -- how do I find the correct WLAN name and where do I need to insert it?
Here's my existing .conkyrc:

Seemingly just to confuse users, there are many different network entries possible -- whether this is related to hardware/drivers, exact version of Ubuntu, or something less sensible is hard to be sure. Unfortunately, one can't be sure one will find ETH0 or WLAN0 -- but many downloaded scripts will assume this. I had to find the correct wifi name for my particular system. A little Googling found this command:
This command doesn't require superuser privilege, so should be accessible to secondary users, likely even guests. Easily seen is that ETH0 or ETH1 and WLAN0 are nowhere in site. All I had to do to get my Conky network monitor section working correctly was replace every occurrence of WLAN0 in the
.conkyrcwith wlp3s0, and ETH0 with enp0s25 (in case I connect via wired Ethernet). On saving the file, conky restarted, and began correctly reporting my network condition and activity in real time, as it does with CPU load, RAM usage, and HDD i/o.Yeah... Ubuntu (and other distros?) adopted a new naming convention for the interfaces making eth0 and wlan0 obsolete (and thus any code based thereon non-functional).
I suggest everyone just ifconfig and see what your interfaces are called, and then do a Ctrl+F in your conky files, looking for 'wlan0' and 'eth0,' so you can then paste the new names over those entries wherever they appear in the code. Here is what I get with an ifconfig:
ifconfig shows your interface labels
This means that network related tasks for conky files you download can no longer be guaranteed to work even IF the developer knows about the new naming conventions because the names are specific to YOUR computer. For example, on my computer, my wlan0 is now wlp2s0 whereas on yours it is evidently wlp3s0. So even my updated conky files won't work right until you do the find/replace for the interface labels to reflect your interface names.
This raises an interesting question. Should we conky developers bother even changing the files from wlan0/eth0 if we intend to offer them for others to download? Wouldn't it be more difficult for them to search for whatever my computer calls my interface than the traditional labels? I guess we could make a nice #note to inform people what to edit and where inside the conky files regardless.
Or we could tell people to search for 'wlp' or 'enp' to find the entries and replace them with theirs if they differ from what their ifconfig says. But is that uniformity confirmed even at the partial level such that we know that all interfaces will at least start with wlp or enp even if the rest is different? How much of this naming convention is universal versus unique? I shall dig for some more info so conky file developers can figure out how to proceed.
I used "ip a" in terminal and it listed all - look for the one that's active and it'll have the name to put in place of "wlan0" - had same problem...
