Answer
Why does Starlink Wi-Fi get worse when I add another extender?
An extender needs a good connection back to the network it is extending. Placing it in an existing dead spot can repeat a weak connection, while overlapping devices can compete for wireless airtime.
Temporarily remove the newest extender and repeat the same test from the same location. If reliability returns, inspect that extender's position, operating mode and connection to the main router.
Check whether it creates a separate routed network or a confusing duplicate network name. Compare a wired access point where practical, or use compatible mesh equipment with a clear layout.
Add coverage equipment one unit at a time and test both nearby rooms and the original problem area. Keep the simpler configuration if the extra device provides no measurable benefit. More boxes are not automatically more coverage, and an extender cannot improve the outdoor satellite link.
