Sorry to hear that you are still having issues. You've mentioned this before, and it makes me wonder what / how your network is configured, and whether there is anything that could be done to help. If you don't mind me asking, are you using the Starlink WiFi directly? When you have downloading issues, have you run speed tests with the Starlink and at speedtest.net to see how different they are (or not)? Is it a major website?
Even in heavy rain here, we haven't seen weather related slowing. We do have occasional outages (usually less than a second, rarely three seconds or so), but those can be seen in the app. We've had a handful of times where the local, and Starlink speeds were high, and something was off getting out of Starlink's network (e.g. not being able to connect to Google.com, or speedtest.com).
For us, the upgrade to Gen 3 made a noticeable improvement in the speeds, and reduced latency, and the WiFi does carry much farther. The only websites that occasionally I have trouble with are not mainstream websites, which makes me suspect that their website is hosted at a site that runs out of capacity.
All the best,
Peter
