# Xfinity slow internet in United States: tests, evidence and complaints

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

Applies to: Xfinity Gateways XB6, XB7, XB8 and XB10 with the current Xfinity app (menus as of 2026). Older XB2 and XB3 gateways show more settings in the Admin Tool. · Checked: 3 November 2026

## When this helps

- You use Xfinity in United States.
- Your connection is slower than expected, drops out or performs badly at certain times.

## Check your Xfinity Gateway

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

1. Open the Xfinity app; an outage banner appears if your area is affected.
2. Tap **View outage details** for the cause and estimated fix time.
3. Without the app, use the Xfinity Outage Map on xfinity.com/support, or text `OUT` to `266278`.
4. To see your public IP, tap **WiFi › View WiFi equipment › Advanced Settings › LAN & WAN**.

## Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see [the Xfinity Gateway guide](https://kilobat.app/routers/xfinity-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.

## How to complain to Xfinity

Use [Xfinity’s official support](https://www.xfinity.com/support/articles/check-service-outage) to report the fault. Request a formal complaint reference if it remains unresolved.

Include the plan wording, dates, test conditions, previous references and the specific outcome you want. Ask for a written response.

For the local escalation route and conditions, follow [the United States complaint guide](https://kilobat.app/guides/us-internet-speed-fcc-complaint).

## Collect the evidence with Kilobat

On a Mac, Kilobat can record connection checks and produce a support report. Review the report and add your test conditions before sharing.

The basic report export is free. [Kilobat Pro’s complaint wizard](https://kilobat.app/internet-complaint) helps assemble your evidence, impact and requested resolution into a draft you review and send.

Measurements cover this Mac while monitoring ran. They cannot prove whole-home uptime, establish provider fault or replace a required official measurement procedure.
