I understand that you need to replace a deffective SlingLink Turbo 4 port unit since it no longer works for you.
Since the SlingLinks Turbo (1 and 4 ports versions) are sold in sets of two units, it is not possible to get one of the units only. Now, you need to base your decision in order to know which one will work for you.
Just to refresh some information for you, I encourage you to check the following link in order to get all the information about the SlingLinks.

I have the same problem. I have read your suggestions, however you didn't answer the question regarding mixing SlingLink 1-port units from different systems. If I purchase the SlingLink TURBO 1-port, will it work with a SlingLink TURBO 4-port from my current setup? If you can mix units then I can save $70.
If it helps, I think I may have found the cheapest solution. I took a shot in the dark and ordered a single SlingLink Turbo W1 from a seller on eBay. These are normally distributed to Dish Network customers but a slew of people are selling the device new on eBay and Amazon. After shipping the whole unit set me back around 15 bucks. I plugged it in where the burnt out box used to be and it worked PERFECTLY. The W1 started feeding internet to the existing 4-port SlingLink Turbo that I have in the living without a single hitch. I wish everything worked as easily as this. For $15, this is the way to go.
If I purchase the SlingLink TURBO 1-port, will it work with a SlingLink TURBO 4-port from my current setup?
Yes, they both work in the same way, so you won't have any issues if you mix them. Another important detail to mention is that you can expand your network and add up to 16 SlingLink devices throughout your house to connect all your devices to the Internet. You can find more information here,
Regards and hope this helps
