Why is my 1 gig internet only 100mbps?

Troubleshooting a 1 Gigabit Internet Connection Running at Only 100 Mbps

Gigabit internet offers lightning-fast download and upload speeds of up to 1000 megabits per second (Mbps). However, if your Gigabit connection is only providing 100 Mbps, you may be experiencing a bottleneck somewhere in your network. Here are some potential causes and troubleshooting steps to resolve this issue:

Signal Interference:

• Check for any wireless devices or appliances (e.g., microwaves) operating near your router or modem. These devices can emit electromagnetic interference that disrupts Wi-Fi signals and slows down internet speeds.
• Move your router or modem away from potential sources of interference.

Faulty Hardware Connections:

• Inspect the Ethernet cables connecting your devices (computer, router, modem) for any damage or loose connections. Ensure they are properly plugged in on both ends.
• Try using different Ethernet cables to eliminate the possibility of a faulty cable.

Network Infrastructure Issues:

• If you have a switch or hub in your network, examine the switch for any loose connections or faulty ports.
• Contact your internet service provider (ISP) to ensure there are no issues with their network infrastructure that could be affecting your speeds.

Ethernet Port Limitations:

• Check the Ethernet port on your computer or device to make sure it is capable of supporting Gigabit speeds. Some older Ethernet ports may only handle up to 100 Mbps.

Troubleshooting Steps:

1. Check Cable Integrity: Unplug all Ethernet cables and inspect them for any visible damage or breaks. Replace any damaged cables.
2. Examine the Switch: If you have a switch in your network, power it down, unplug all cables, and wait for a few minutes. Then, power it back on and reconnect the cables one at a time, checking for any improvement in speed.
3. Verify All Connections: Ensure all connections between your devices and the network are tight and secure. Try plugging your computer directly into the modem to bypass the router and eliminate potential issues with the router.

If you have followed these troubleshooting steps and are still experiencing slow speeds, contact your ISP for further assistance. They may be able to perform additional diagnostics on their end or schedule a technician visit to resolve the issue.
