Bright House 200/15 connection. Line test shows rated speed.
Gigabit dumb switch and Gigabit SonicWall firewall
All internal wiring is Cat5
DHCP and DNS handled by domain controller.
Using Speedtest.net (and other metrics software)
Local domain workstations (Gigabit NIC) get 60/16
BH tech's laptop connected directly to modem with Cat6 patch cable gets 210/16 with both static and DHCP addresses.
My laptop (Gigabit NIC) connected directly to modem with Cat5 patch cable gets 65/16 with both static and DHCP addresses.
My laptop (Gigabit NIC) connected directly to modem with Cat6 patch cable gets 135/16 with both static and DHCP addresses.
Why would my laptop and its gigabit NIC be so much slower than the techs, when we are using the same Cat6 cable? Granted, my laptop is pretty old, and has a 1st Gen i7 CPU. I'm sure his is a 5th Gen i7. But I didn't know CPU speed would affect a bandwidth test that much.
Also, is Cat5 cable really not able to transfer at 200mp/s? Do I need to re-cable my entire office with Cat6?
