My phone reaches roughly 60–80 Mbps over Wi‑Fi, but my PC only gets about 3 Mbps. I tested both devices in the same location, so distance from the router doesn't seem to explain the difference. The PC appears to use an Intel Wi‑Fi 6 AX200 160MHz adapter, and I'd prefer to avoid running Ethernet if possible. What should I check or change to improve the PC's wireless speed?

The connection is only as fast as the weakest or most congested part of the wireless link. Older devices, nearby networks, walls, and several devices using Wi‑Fi at the same time can all reduce throughput. If troubleshooting doesn’t help, Ethernet will usually provide the most reliable result, but testing different bands and updating the adapter settings is worth trying first.
Wi‑Fi interference is another possibility. Phones are often better at handling weak or noisy signals and may switch channels or bands more effectively than a desktop adapter. Use a Wi‑Fi analyzer app to check signal strength and congestion around the router and PC. If possible, try the less crowded 5 GHz band, adjust the router’s channel, or reposition the router and PC.
The PC’s wireless adapter, driver, or adapter settings could be limiting the connection. Even though the AX200 supports fast Wi‑Fi, check that its drivers are current and that it isn’t set to an older wireless mode, reduced channel width, or power-saving setting. Comparing the negotiated link speed on the PC with the phone can also help identify whether the problem is the adapter or something else.
