Thanks for using our Answers Forum. I understand that you are looking for an alternative to Slinglinks. There are many many alternatives for Slinglinks available, you will need to research and find the best fit for you. I can recommend one alternative to you, that would be a HomePlug. Netgear and ActionTec both make very affordable models of these. The data rate we recommend is at least 200 Mbps.
Hope this helps.
