My Lenovo IdeaPad Flex 5 frequently loses its Wi-Fi connection, and I have to disconnect and reconnect before it works again. I've already updated the wireless drivers, removed and reinstalled them, and adjusted the battery optimization settings. Would trying a USB Wi-Fi adapter be a sensible next step, or should I replace the internal wireless card with an AX210? I don't need especially high speeds—I mainly want a stable connection. Are there any other tests I should do first to confirm whether the adapter is actually the problem?

If you use a USB adapter, plug it into a USB 3.x port if possible; the port may not be blue, so check the laptop specifications instead of relying on the color. Also disable power saving for the wireless adapter in Device Manager and try temporarily using the 2.4 GHz and 5 GHz networks separately. That can reveal whether one band is causing the dropouts.
An AX210 can be a solid replacement, but laptop compatibility matters. Check whether the internal card is a standard replaceable M.2 Wi-Fi module, whether the antenna connectors fit, and whether the system has any hardware restrictions. I’d test with a USB adapter first rather than opening the laptop immediately.
A USB adapter is a good first test because it’s quick to install and easy to remove. If the connection stays stable with the USB adapter, that points more strongly to an issue with the laptop’s internal wireless card or its driver. Try to borrow or buy an inexpensive one before opening the laptop.
Before replacing hardware, test whether the problem happens on other networks. If it only happens at home, the issue could be the router, interference, signal strength, or a compatibility setting rather than the laptop. Connecting by Ethernet for a while is also useful: if Ethernet remains stable while Wi-Fi drops, you can narrow the problem down to the wireless connection.
That makes sense. A USB adapter should show whether the problem follows the laptop’s network connection or is limited to the built-in card.
