I have had network issues the last week and this was the suggestion that helped me the most:
make sure to separate the 2.4 and 5ghz networks in your router. If you can pause the 5ghz, that may help. If your router cant have separate networks for 2.4 and 5ghz, consider a cheap extender that only projects 2.4 ear your printer.
(I have an eero and ended up buying a cheap $10 extender on Amazon that I can have do only 2.4ghz, installed it near the printer, and now it works).
