It appears those are network stats for UDP (user datagram protocol). It's another protocol that's used in conjunction with IP, usually for applications that don't require reliable data transmission. The TCP section should be the first displayed. You can try the command 'netstat -s | less'. The vertical line before less is the pipe character (hold shift and press the backslash key). You can now scroll through the output with arrow or pgup / pgdn keys. Here's an example of output for the TCP section when I run netstat -s as root on my Mac (output truncated for length):

tcp:
        6094285 packets received
                5166105 packets (3033536317 byte) received in-sequence
                3831 completely duplicate packets (2903268 bytes)
                103 old duplicate packets
                0 received packet dropped due to low memory
                32 packets with some dup. data (11212 bytes duped)
                589 packets received after close
                47 bad resets
                0 discarded for bad checksum

Here's the columns of output of netstat -i for my wi-fi adapter showing Ethernet stats:

Ipkts       Ierrs    Opkts       Oerrs  
6697785     0        6257972     0

Ierrs shows how many errors the wi-fi adapter encountered out of the number under Ipkts received.

All zeroes.  Is that good or bad?? 😳

@elliottbnewcombjr , thanks!  That's exactly what I've done, as I mentioned in one of my previous posts.

You are far better off with a combo modem,router this is much faster having a 3.1 modem vs the obsolete 3.0 ,it is much faster without question my speed doubled ,

and wifi signal Excellent , with coupon at Amazon under$250  could not be happier.

Motorola MG8702 | DOCSIS 3.1 Cable Modem + Wi-Fi Router (High Speed Combo) with Intelligent Power Boost | AC3200 Wi-Fi Speed | Approved for Comcast Xfinity, Cox, and Charter Spectrum

Audio streaming does not need much speed, a few hundred kilobits per second at most. The router can send tens or hundreds of megabits around the network. So you really need a lot of devices going at once before you have worries about an audio stream keeping up.

An old TP-Link Archer A8 serves my system just fine. Last I looked, under $100 in the U.S.
