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 consider replacing the internal card with an AX210? I don't need especially fast speeds—I mainly want a stable connection. Are there other troubleshooting steps I should try first to determine whether the wireless adapter is actually the problem?

Try an inexpensive USB Wi-Fi adapter first. It’s quick to set up and gives you a way to test whether the laptop’s built-in wireless adapter is the source of the problem without opening the computer.
An AX210 can be a good internal replacement, but check your exact laptop model before buying. Some laptops have compatibility restrictions, different antenna or connector requirements, or an internal card that isn’t intended to be easily upgraded. A USB adapter is the simpler first test.
The external adapter will be easier to install and remove if it doesn’t solve the issue. Plug it into a USB 3.x port if possible; the port may not be blue, so check the laptop’s specifications rather than relying on the color. If you can test with Ethernet too, that will help narrow things down: if Ethernet is stable while Wi-Fi drops, the wireless connection or adapter becomes more likely.
I don’t have a blue USB port, but the specifications say the ports are USB 3.x. I’ll also look for an Ethernet cable so I can compare the connections.
First determine whether the problem happens on every network or only at home. Try another Wi-Fi network or a phone hotspot. If it only fails on your home network, investigate the router, interference, security settings, and whether the network name is hidden before replacing the laptop’s adapter.
Since the cause isn’t confirmed yet, buying a new internal card could waste money. Check whether the issue continues in different locations, test with Ethernet or another adapter, and review the router logs or power-management settings. Those tests should tell you whether the laptop hardware is really at fault.
That makes sense. Testing with an external adapter first seems safer than immediately replacing the internal card.
