please note that there are reports of TP-Link TL-WN321G V4 not working with our DM 800HD. TP-LINK support says it uses RT2070L chipset. However, TL-WN321G V3 works fine and TP-LINK support says it uses RT2571. Therefore, it seems that not only RT73 but also RT2571 works fine.
Is there a way get this version also supports? thanks
