Question about Netgear A6210-100pes

According to my information, other products outside of Sony are not compatible or only partially compatible. You would effectively have to test this yourself, as there is no corresponding compatibility list or other references. Or you can simply buy the UWA-BR100 WLAN stick from Sony. Unfortunately not available at Digitec. An alternative might be a repeater that you can connect to the LAN port to access the WLAN: TP-LINK TL-WA855RE : WLAN-N Repeater
