Amazon’s older Kindles will start to lose their internet access in December - The Verge

As Good e-Reader first noted in June, newer Kindle devices with 4G support should be fine, but for older devices that shipped with support for 3G and Wi-Fi like the Kindle Keyboard (3rd generation), Kindle Touch (4th generation), Kindle Paperwhite (4th, 5th, 6th, and 7th generation), Kindle Voyage (7th generation), and Kindle Oasis (8th generation), users will be stuck with Wi-Fi only.

Things get more complicated for Amazon’s older Kindles, like the Kindle (1st and 2nd generation), and the Kindle DX (2nd generation).

For customers affected by the shutdown, Amazon is offering a modest promotional credit (NEWKINDLE50) through August 15th for $50 towards a new Kindle Paperwhite or Kindle Oasis, along with $15 in-store credit for ebooks.
