# Optimum (Altice USA) slow internet in United States: tests, evidence and complaints

If your Optimum (Altice USA) connection is slow or unreliable, start with these equipment checks. Then document a repeatable result and ask for a specific investigation.

Applies to: Optimum Gateways (Gateway 5 and newer) and the Altice One box with a built-in gateway, as described in Optimum’s help pages in 2026. The app notes that its features depend on your equipment. · Checked: 3 November 2026

## When this helps

- You use Optimum (Altice USA) in United States.
- Your connection is slower than expected, drops out or performs badly at certain times.

## Check your Optimum Gateway

These checks apply to Optimum Gateway. Check the model before following its menus.

1. Check the Gateway’s front panel; it is online when **POWER**, **DS/US** and **ONLINE** are solid green.
2. In the My Optimum app, tap **WiFi › Troubleshoot my Internet** and follow the steps.
3. Tap **WiFi › More Options › Check my Internet speed to the Gateway** for a speed test.

## Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see [the Optimum Gateway guide](https://kilobat.app/routers/optimum-gateway).

Do not factory-reset the equipment as a first step. A reset can erase service settings and interrupt phone service.

1. Compare a wired connection to the router with Wi-Fi on the same device.
2. Repeat the same test server during the slowdown and at a quieter time.
3. Record download, upload, latency and whether another household device was using the connection.
