Google Confirms Bug Made Home Speakers Overuse Wi-Fi Data

A server misconfiguration caused some Google Home Speakers to repeatedly download a software update over roughly the past two weeks, consuming unusually large amounts of home Wi-Fi bandwidth, according to a Google spokesperson quoted by WIRED. The company said the issue has been resolved, though it did not specify how many devices were affected or when the fix was fully deployed.

What caused the Google Home Speaker's data overuse?

According to the Google spokesperson's statement to WIRED, a misconfigured server prompted some Gemini-powered Home Speakers to download the same software update again and again instead of completing it once. The result, WIRED reported, was a repeated download loop that ran in the background without a clear signal to the user that anything unusual was happening. Google's statement did not identify the root technical cause of the misconfiguration or say whether it originated with a specific firmware push.

How much data did affected speakers consume?

The scale varied by household. WIRED reported that one Reddit user, first flagged by 9to5Google, found his Google Home Speaker had used roughly three terabytes of data over a two-week span. WIRED's own reporter checked a personal network after reading those posts and found a Home Speaker had used 487 gigabytes of data in ten days — described in the report as "almost as much as the entire rest of my home between August and September." Google told WIRED the bug "has only affected some devices," without estimating what share of its installed base was involved.

Has Google fixed the bug?

Google's statement to WIRED says the issue "has now been resolved," attributing the fix to a correction on the server side rather than a required update on individual speakers. WIRED's report does not include independent verification that usage has dropped back to normal across all affected units, and no third-party confirmation of the fix's completeness was cited.

Are other smart home devices affected too?

WIRED's reporter also reviewed broader router logs after the Home Speaker discovery and found other anomalies. A device identified only as "Amazon" — tied to a Ring smoke detector in the household — was recorded using 22 gigabytes over one week, comparable to a smartphone's usage in the same period. A separate device labeled "WATCH" used about 21 gigabytes in a week despite no smartwatch having been active in that home for roughly a year, according to the report. WIRED described the Amazon and "WATCH" findings as unresolved and did not attribute them to a confirmed bug, cause, or vendor statement.

Data snapshot from the WIRED report

• Reported Google Home Speaker usage: as much as 3 terabytes over two weeks for one user; 487 GB over 10 days for WIRED's reporter.
• Ring-linked "Amazon" device usage: 22 GB in one week.
• Unidentified "WATCH" device usage: 21 GB in one week.

How can users check which devices are using the most data?

WIRED outlined a method for readers to estimate usage themselves. Some mesh routers log per-device traffic, though the feature can sit behind a paid subscription tier. WIRED noted that an Eero system's free tier lists connected devices but does not break out data volume per device without a paid plan. By contrast, the report said Asus routers allow data tracking and traffic analysis without a subscription, through the router's Traffic Analyzer tool accessible at the router's web interface. The underlying method is straightforward: log into the router's administrative panel, locate the per-device traffic or history log, and compare data volume across the devices on the network over a comparable time window.

The findings so far rest on a single company statement and a small number of user reports collected by WIRED and the Reddit threads it cited; no independent measurement across a larger sample of Google Home Speakers has been published. Readers concerned about unexplained data spikes on their own networks can apply the same router-log check WIRED described, though identifying the cause of any anomaly — as the unresolved "Amazon" and "WATCH" entries show — is not always straightforward even with detailed logs.
