We would like to inform that recent Intel® Wireless Adapters do not support Hosted and Ad-Hoc networks. We are not able to recommend any way to use your laptop as hotspot in Windows 8.1*.
We would like to add that Windows® 10 version 1607 (Windows® 10 Anniversary Update) introduces a similar feature called the mobile hotspot, which is based on Wi-Fi Direct and allows sharing internet through a supported Wi-Fi adapter.
For more information, please review the following document: Why Hosted and Ad-Hoc Networks are Not Working on Windows® 10.
