I have found that in version 1.2 for tyros 3 there is wireless usb adaptor but my question is about the list of adaptors it is impossible to open the list !!!!
Hi moshe israeli,
YES, your are right here. I had completely forgotten that yamaha in the latest Tyros3 firmware (V1.20) had added a support for USB Wireless LAN adapter.

BUT as mentioned before: Yamaha has CLOSED these specific websites that could be accessed by integrated browsers of some keyboards (such as Tyros3/Tyros4). There are no more download shop pages that could be accessed directly from the keyboard browser, and the "Music Finder +" service has also been discontinued.
Therefore, even if you would find a USB stick that works with the Tyros3, you could not do anything with it in my opinion.
P.S.
I still remember that I had used a "HAMA" USB wireless LAN adapter on my Tyros
4, but I do not remember the exact type.
P.P.S.
Here are old IDC websites that are still online, but the IDC services, to my knowledge, are all closed now:

Best regards,
Chris
