Smart Firewall's Network Trust list does not work correctly on WiFi-connected PC

I've had this ongoing problem with two of my PCs, a laptop and a desktop, both of which connect to my router via WiFi. About once a month, other computers on my router's local network are suddenly unable to connect (via network shares or via `ping`) to one of the WiFi-connected PCs. Up until today, I've been able to get sharing working again by following these steps (BIGBYTE is my router/LAN):
1) Settings > Firewall > scroll down to Network Settings > Network Trust, temporarily change the trust level of the BIGBYTE _network_ (at 192.168.0.1) to “Full Trust”, and if all connections are working again, set it back to “Private”! (IF N/G, continue...)
2) If the Network Trust list was inexplicably EMPTY, go back to Device Trust and add BIGBYTE as 192.168.0.1 with "Full Trust". Now it should show up in Network Trust, and I should be able to remove it from Device Trust without impacting my network access (and REBOOT?). (IF N/G, continue...)
3) If the Network Trust list is EMPTY again, but BIGBYTE is still in Device Trust (and obviously not being honored suddenly!), remove it; then it will magically reappear in the Network Trust list! *** MIGHT HAVE TO REBOOT AFTER EITHER OF THE ABOVE! *** (IF N/G, continue...)
Today, suddenly the above steps did NOT fix the problem. I ended up having to do the following to get sharing working again:
4) I added every other computer on my local network (there are FIVE), to the Trusted Devices list!
I think you'll agree with me that I should NOT have to do #4, that having my BIGBYTE network in the Network Trust list as "Private" should be sufficient.
I never have these issues on the computers on my network that are connected via ETHERNET. Why is Norton 360 giving me such a hard time with the ones that are connected via WI-FI?

I've been dealing with this problem for so long, and until yesterday I'd found a solution each time, only to find that the next time, that solution didn't work. But your comment about Network Trust got me thinking: if the network name appears there automatically, then why did it occasionally disappear (see #2 above)? Must be because the network wasn't visible at the time – maybe the WiFi adapter had been powered down or asleep during the night, and Smart Firewall thinks that is still the case? (in spite of the fact that I do have internet access and can connect to my other PCs, but they just can't connect to me...)
So I removed everything from the Device Trust list, disconnected from WiFi, and confirmed that now there's nothing in Network Trust. I reconnected to WiFi, and confirmed that the network name has reappeared in Network Trust. And now file sharing is working as it should! Apparently this is a WiFi adapter issue (on two different PCs), but it is strange that I still have full internet access and outgoing file sharing, at a time when Smart Firewall doesn't "see" the network – that seems to corroborate my statement that Smart Firewall's Network Trust list does not always work correctly on WiFi-connected PC.
Anyway my new solution, when this happens again, is to disconnect from WiFi and then reconnect. P.S. I set the Network Trust level to "Private", not "Full Trust".
