Those Wifi losses seem a bit high, I'll have to try that here.

Small loses, AFAIK the problem is router ←→ SW2. Notice the strangeness that SW1 is in the middle, but pings from a machine connected on SW1 pinging the router seem not to be affected (recollection say they were affected when the technician looked).
I just tried fping to my Asus WiFi router from a HP laptop and got better numbers. The router is located about 12-meters away with a number of walls and furniture in the way.
192.168.10.213 : xmt/rcv/%loss = 100/100/0%, min/avg/max = 0.03/0.05/0.07
Notice the round-trip packet times though! You've got 112-msec max! My packet times are more than three-orders of magnitude less than yours! IIRC NM reported 62% signal strength when it connected. Do you have access to another WiFi hub that you could plug in temporarily for testing?
Yes, near SW2. It doesn't serve to test router or SW1. Older WiFi, actually. Doesn't bother me, the wifi speed or latency. Not a problem. Packet loss is.
My WiFi router is fed from my Zyxel router/firewall which is fed from my Motorola DOCIS 3.1 cable modem, not that it makes any difference here.
