I tried several searches on the forum and didn't come up with anything that matched my issue. I just received a pair of SXTsq 5 ac units and I have issues getting them programmed. My goal is to connect two buildings 400 feet apart. Within the last 18 months I have successfully set up 2 pair of SXT Lite5's, so this has me stymied. I can program one unit as PTP Bridge CPE with static IP and Gateway addresses just fine. When I refresh Winbox (v. 6.49.10) the unit remains visible. When I program the second unit as PTP Bridge AP with static IP (different numbers, of course) and Gateway addresses, when I refresh Winbox it has disappeared. Manually inputting the MAC or new IP address does no good. Searching the IP address directly from the browser does no good, either. Any suggestions?

Correction - Winbox 3.40, SXT software is 6.49.10
