is this adapter compatible ith linux?

this has an AR9485 chipset and the internets are riddled with complaints mostly due to poor linux drivers (ath9k). The issues go back years and no solution at sight so proceed with caution..

Will it work for Ubuntu?

The TL-WN781ND is designed for use with Windows systems. For drivers, please visit our website here: https://www.tp-link.com/us/support/download/tl-wn781nd/#Driver Regards, TP-Link Support

Is the TL-WN781ND currently (02/2014) sold by Amazon the version 2 card or the version 1 card?

does this come with both low profile bracket and regular?

Yes. Both brackets were in the box.
