Internet & phn in separate jacks, wi-fi lost when phn used. Will this fix prob?** A: what this device does - it sends (extends) telephone + ethernet over the FIBER optical cable. Not quite sure what in your case is the splitter, it would be better if you could send us some photos, and more explanation of your setup you want to achieve to us at support@ad-net.com.tw so we can look further ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what I need *by R***N on March 5, 2021* Product shipped quickly.
