I am building an RFID reader based timing system for running races. This will be a portable system for outside.I have 2 Motorola fx7400 readers connected to a TP Link wireless router via LAN. I have set the preferred client IP addresses for each reader at 192.168.0.102 and 192.168.0.103. I did this as the readers seem to need to maintain their auto DHCP selection or they become impossible to connect to when DHCP is turned off. The problem lies in when I connect the router to the internet (both wirelessly as a range extender, (preferable as this will be how I will connect to my phone hotspot in the field)) or hardwired as a secondary router, I lose communication with my readers. I suspect the internet connection is reassigning my IP addresses but I am unsure. My question is this: How can I maintain my dedicated network of readers while gaining internet access for just my laptop? I am guessing a managed ethernet switch, or is it as simple as reassigning IP addresses? Thanks for any help!
