  In addition to the long-standing anomalies seen in the muon $g-2$,
$R_{K^{(*)}}$, and $R_{D^{(*)}}$ observables by various independent
experiments, the CDF Collaboration has found another significant one in the
$W$-boson mass. These anomalies might be intertwined at a fundamental level and
have a single new-physics explanation. In this paper, we present a simultaneous
solution to these anomalies with two scalar leptoquarks of roughly equal mass
-- one weak-singlet $S_1$ and the other a weak-triplet $S_3$ -- which mix
through a Higgs portal. The solution has only a few new couplings and TeV-scale
leptoquarks, making the solution testable at the LHC. We put a lower and upper
bound on the leptoquark masses in this setup from the current LHC data and the
assumption that all new couplings are within the perturbative limit.
