The only potential I see that *might* exist for any sort of adverse impact would be a possible drop in data throughput by daisy chaining ethernet connected devices. The only such personal experience I have is a few years ago, the company I worked for began replacing our desk phones from a traditional phone to digital/VoIP Cisco phones. In order to save on costs of running new/additional UTP cabling out to the thousands of cubicles in our office complex, the network/telecom team decided to set up every office with the Cisco VoIP phone connected to the existing network port in each cubicle, and then daisy chain our laptop/desktop to the Cisco phone. Horrendous network performance drop! If you plugged your laptop/desktop into it's own LAN port, you got back to your normal network performance.
