The border between Mexico and the US is 1,954 miles.
Under Trump about 400 miles of fencing that was built under Obama was replaced or repaired by new fencing and about 40 miles of actual border wall was built where there was no previous barrier.

Trump closed the gaps in previous fencing and strengthened the most vulnerable sections:
But then, Biden paused the work as soon as he came to power. And the Mexican president (Andrés Manuel López Obrador) was full of praises for exactly the same reason:

“You, President Biden, you are the first president of the United States in a very long time that has not built even one meter of wall,” López Obrador said. “And we thank you for that, sir — although some might not like it, although the conservatives don’t like it.”

So Trumps wall was working great and then when Biden became president it just stopped working. Does that really make sense to you? Do you think it's a magic wall?
The reality is that the broken US immigration system can only be fixed by congress. Neither Trump nor Biden have/had the power to fix it. If any president were to blame it would be LBJ or Nixon for destabilizing Latin America 40 years ago. Executive orders may have some short term affect, but they can't solve the underlying issue. And the wall is nothing but a gimmick that Trump used to excite the mouth breathing xenophobes that worship him.
