Interesting issue:
I have been running WIFI with no issues in seeing my HP printer, a 2015dn. The printer is on the wired LAN. There is a wireless b/g access point and 3 repeaters. One does b/g. The other two repeaters (ASUS RT-AC68u) do wireless b/g/n/ac and create another SSID for the 5G network,
When using the wireless network from my laptop, I was able to see the printer from everywhere. When I plugged into the b/g repeater, I saw the printer. When I plugged into one of the ASUS repeaters, I was unable to see the printer without adding an ARP entry.
I did not try the other repeater, nor did I try adding the ARP entry temporarily on the ASUS repeater.
Wireless crapped out on my laptop, so I went wired through the repeaters.
Why did I need the ARP entry?
