These days a lot of questions are asked about problems with Realtek rtl8188be, rtl8723be, rtl8188eu and many other cards. Solutions are same. But it is hard to find them. I can't find solutions unless I look into my answer history.
I think it makes sense to get these adapter names synonyms to
realtek tag. Or create a
realtek-wireless tag. But the second will take some work to retag. Most of "realtek" questions are regarding wireless either way.
