Athena was always on his side. If you mean in the hall when he returns, her shield appears and the other suiters in the room trying to claim his wife and fortune know the Gods are on his side.
Athena is the goddess of war and Odysseus was in the war. It is her responsibility to help him.

Athena first takes the form of Mentor. When Odysseus calls to her for help, she berates him for being so weak and needing to call on the gods for help. She takes the form of a swallow and watches the battle from the rafters. When the suitors throw their spears at Odysseus and his men, she makes the spears mostly miss. Further, she helps guides Odysseus and his men's spears into the suitors. Finally, Athena holds up her Aegis, making the suitors cower and despair as Odysseus and his men slaughter them.
She directed winds that took him to Phaecia

Circe, Calypso, Ino, and Nausicaa help Odysseus. Athena helps Odysseus as well.
Athena tells Zeus that Odysseus is favored by the gods because of his resourcefulness, bravery, and intelligence. She reminds Zeus of Odysseus's loyalty to him and his role in winning the Trojan War, which should make him deserving of help on his journey home.

Athena helped Odysseus because she admired him and he reminded her of herself. Also because he showed piety and gave her prayers and sacrifices.
Athena does help Odysseus in his fight against the suitors, just not directly.She helps Odysseus' side's spears find their targets and helps the suitors miss theirs. Further she helps motivate Odysseus reclaim his battle-like demeanour in the face of so many men.Athena wishes for Odysseus to have the glory himself, and for him to remember what it was like to be a fierce warrior like that in the Trojan war. She chastises him for calling for Mentor's help, likening him to a coward.
