Wireless worked in Robtech’s test
Robtech reported working Bluetooth and a full Valorant session over 5GHz Wi-Fi without network warnings. His router was about 12 metres away. He cautioned that one successful sample does not establish consistent wireless performance across units.

Wi-Fi struggled in Team Pandory’s test
Team Pandory could not complete an online speed test using the original Intel AX200 wireless card in his setup. Replacing it with a MediaTek RZ616 allowed the test to run. This differs from Robtech’s experience; their networks and units were not tested under identical conditions.

Batocera 41 connected to wireless devices
Team Pandory reported that Batocera 41 booted, connected to the local Wi-Fi network and paired with a Bluetooth controller. This checks basic connectivity on that review unit, not sustained wireless throughput or every Linux distribution.
