Why can't I get gig speed on my wired network connection

Hi Vince! My name is ***** ***** it is my pleasure to assist you today.

"Gigabit" ethernet speed has a theoretical maxmium throughput of 125MB/s; however, the actual data throughput can be slowed considerably by any number of possible bottlenecks.

The most common limiting factor is your computer's internal hard drive. If you are not using a solid state drive in your PC, you most likely have a newer-generation SATA drive installed instead. These drives provide for a sustained data transfer rate of about 65MB/s, or about half of your theoretical maximum connection speed assuming the drive dedicates its entire bus to receiving download data.

Other possible bottlenecks include networking equipment (including cabling), as the network speed will only operate at the highest common denominator. If you have an older PC connecting somewhere in your network, your network speed will slow down to that device's maximum data transfer speed.

It's hard to provide a more specific answer to your question being unfamiliar with your equipment, but I hope that above helps provide some explanation! If you have any further questions, please let me know.
