How do you fix packet loss?

Packet loss means some data does not reach its destination. Even a small amount can matter for games, voice chat and other real-time traffic.

PACKET LOSS TROUBLESHOOTING

Start by finding out whether the loss is inside your home network or beyond it.

Run the test more than once, then compare Wi-Fi with Ethernet. If the problem disappears on a wired connection, focus on signal and interference. If it remains wired, check local equipment and then the broadband connection.

Re-test over Ethernet

A wired connection removes most local wireless variables. If packet loss drops to zero on Ethernet, investigate Wi-Fi coverage, interference or mesh placement.

Pause background traffic

Large downloads, uploads, backups and updates can overload queues or a busy router. Stop them temporarily and repeat the test under a quiet network.

Restart the router and modem

A clean restart can clear temporary software or connection-state problems. Give the connection time to come fully back online before testing again.

Check cables and Ethernet ports

Damaged cables, loose connectors or a problematic router port can cause retransmissions and instability. Try another known-good cable or port where possible.

Update network equipment

Router firmware, network drivers and mesh software can contain stability fixes. Keep the network stack current before assuming the line itself is at fault.

Escalate persistent wired loss

If repeatable packet loss remains on Ethernet with a quiet network, record several tests and contact your broadband provider with the times and symptoms.
