I was hoping by purchasing this update version of a switch I already owned it would solve my problem, but it didn't. I have an internet system that uses 5G on the wireless side, and only 2.4Ghz on the wired connected ethernet cable side, after replacing the switch and even updating the ethernet cable, it didn't do what I had hoped. I hoped it would step up the 2.hGhz to the 5G, there is no success. This switch maybe exactly what you are looking for, it's easy to install. While says it support 5G, it doesn't step up the Ethernet cable plugged into the switch and router to 5G. Disappointing, but that's life.
Yes, I still have two. I gave the consumer model to a family member. This switch (GS 308x) is fast, works on my 12vdc distro panel adapter. LOVE the quality, the warranty period, this won't be my last unit.
