First of all, you can use this link: https://1drv.ms/f/s!AtacZBU04mo-j-tQ34BdSDv6y1BFsg?e=7gn50T to access my driver archive. Subfolders provide drivers that you can use with many of the Discontinued Wireless adapters.
As far as a replacement, there are several cards that you could use if Wireless-AC and WiFi 5 capabilities are considered good enough. Since the cards cost roughly the same, however, I recommend upgrading to the latest Wireless-AX and WiFi 6/6e capabilities. To upgrade to the latest Wireless-AX and WiFi 6 support, you need an AX200 module. For Wireless-AX and WiFi 6e (which supports the 6GHz band), you need an AX210 module.
Since you have a 7260HMW card, there is a small problem: Intel does not manufacture cards in this older formfactor any longer. All is not lost, however; there are 3rd-party companies that take the Intel silicon and mount it onto the older formfactor cards. These cards utilize the exact same drivers as the NGW cards from Intel, downloaded (yourself) from the Intel Download Center, so nothing sketchy here. These cards are slightly more expensive than the Intel NGW cards, however: ~US$30 (due to smaller sales volumes, I think). Here are examples:
These HMW cards are examples only; the ones that I actually purchased and tested are from a company named Fenvi, who doesn't seem to offer card-level products through Amazon (I purchased mine through NewEgg).
Hope this helps,
