Expedition Navigation Software 
Offline
We use the Actisense W2K-1 to connect to our instruments and it used to work just fine with Win10. I upgraded the laptop to Win11 and Expedition to v12.7.16 and it partially stopped working. Expedition still reads and displays GPS (SOG, COG), AIS info and some other PGNs like depth, heel or temperature but no wind data.
I upgraded the W2K-1 to firmware v1.398 but still no luck. I confirmed that all the right PGNs are selected and reset it to default to make sure. I checked the defender firewall settings and tried it even with firewall turned off.
We also use NEMEAremote on an iPad and wind data is displayed. It uses the same data server. We use for both N2K ASCII with TCP protocol on port 60002. I can also see the raw data feed in Expedition.
Does anyone have any idea what I’m missing and may need to adjust on the w2k-1, in Win11 or Expedition?

BR,
You might also try contacting Actisense at

A lot of NMEA 2000 networks don't have TWA, TWS or TWD.
If so, you need to tell Exp to calculate them. It needs BSP, HDG, AWA and AWS at a minimum.

I contacted Actisense about it. They don't think it is related the W2K-1 because NMEA 2000 data including AWA and AWS shows on the iPad that we connect to the same data server from the W2K-1.
We are missing AWA and AWS in Expedition. Turning on the calculation of TWS, TWA and TWD doesn't fix it. I know this problem sounds really weird because some data displays and others doesn't.
I'm not sure whether it helps to determine the root cause but at this link is an exportof the raw data from the instruments in Expedition.
