Comparing the original Baofeng UV5R to the new Mini

I decided to look into my internet connection setup. The motherboard I have for my PC does have WiFi via two small antennas on the motherboard. I am using a TP-Link extender in the hallway,

TP-Link extender

which has a LAN connection. I attached a LAN cable to the TP-Link and plugged that into a TP-Link LAN switch beside my PC. From the LAN switch, one LAN cable went to my PC and the other to the Icom 7610 radio. I tried split toroids on the LAN cables and LAN switch power cable. That did not work. I then just used the WiFi connection on the PC to the TP-Link extender in the hallway—that did not work. I then connected my PC WiFi to the main WiFi from our router in the living room, thinking the TP-Link extender could be the issue, and that did not solve the issue.
