hardwareintermediate
equipment bottleneckspeed constraints
Constraints on internet speed imposed by the capabilities of network equipment such as modems, routers, network cards, or cables.
Examples
Old router
802.11n router caps speed at 450 Mbps even with gigabit internet
Ethernet cable
Cat5 cable limited to 100 Mbps, need Cat5e or Cat6 for gigabit
Optimization Tips
Upgrade router if more than 3-4 years old
Use Cat6 cables for future-proofing
Check network card supports your internet speed
