Nic Speed: Realtek Rtl8192ee Wireless Lan 802.11n Pci-e

From 70 Mbps to 110-120 Mbps in congested areas.

"n" is the last supported generation. This card will never negotiate an 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) connection. Mixing with an ac router forces the router to drop to n mode. realtek rtl8192ee wireless lan 802.11n pci-e nic speed

If you have this card:

Theoretical 300 Mbps is the raw physical layer (PHY) signaling rate . After subtracting Wi-Fi protocol overhead (MAC efficiency, headers, ACK frames, retransmissions), – even under ideal conditions. From 70 Mbps to 110-120 Mbps in congested areas

The card hits its efficient ceiling. You cannot exceed ~180 Mbps with this chip, regardless of router quality. regardless of router quality. On paper

On paper, it supported (since it’s 802.11n with 2x2 MIMO). In reality, she was getting 15–20 Mbps while her phone on the same network got 90 Mbps.
