ASUS VivoBook X540LA Atheros Bluetooth Driver 10.0.3.19 for Windows 10 64-bit 9,822 downloads. ASUS Laptop X407MA Atheros Bluetooth Driver 10.0.3.19 for Windows 10 64-bit. because in ebay, they do write dual band supported thus i not sure my 5ghz issue is that antenna issue or wifi card issueĪs for the Bluetooth issue the guy who sold me this card tell me instead bluetooth driver 1st then follow by wifi driver then install the card to avoid bluetooth unable to detect issue. ĭoes antenna wire in the laptop have bandwidth compatibility issue? ( mean they only respond to 2.4Ghz and weak at 5Ghz unless they are dual band ). I have so far 3 pieces of laptop suffer the same issue. having issue with 5ghz band, using rt-ac66u router and 5ghz is not stable at all although it shows a 98+ mbps speed in speed test but the connection suffering ping problem. Just purchased this Intel 7260 dual band ac card not long ago.
