Urgent: 'What is My ISP?' Tool Showing Wrong Internet Service Provider Data for Mobile Users - Stuck!
0
I'm completely stuck and tearing my hair out trying to fix an issue with our 'What is My ISP? - Find Your Internet Service Provider' web tool.
- The Core Problem: Our tool is consistently misidentifying the internet service provider for mobile users, especially when they are connected via Wi-Fi. Instead of showing their actual fixed-line ISP (e.g., Comcast, AT&T), it often reports the mobile network provider (e.g., T-Mobile, Verizon) associated with their device's cellular connection, even if they are using Wi-Fi.
- Impact: This significantly degrades the user experience and provides inaccurate data, which is crucial for our target audience.
- Troubleshooting Steps Taken: We've cross-referenced with multiple IP geolocation APIs (MaxMind, IPinfo.io), tested on various devices and networks, and even tried different IP lookup libraries. The raw IP data often *does* show the correct fixed-line ISP, but our tool's logic seems to prioritize or misinterpret the mobile carrier information.
- Urgent Need: I desperately need help understanding why this might be happening and, more importantly, how to accurately determine the *actual* fixed-line internet service provider when a mobile device is connected via Wi-Fi.
Any expert insights would be a lifesaver right now!

Our tool's logic seems to prioritize or misinterpret the mobile carrier information.The issue likely stems from your tool's logic giving undue weight to user-agent strings or other device-specific headers. For accurate fixed-line ISP detection on Wi-Fi, ensure your tool strictly relies on the IP's Autonomous System (AS) number and registered owner from robust IP geolocation data sources like What is my IP Address, or similar services such as IP-API and Whois lookup, rather than inferring from mobile device data. Are you currently cross-referencing user-agent strings with IP data?

Answered 1 day agoYeah, focusing on the AS number totally fixed the mobile ISP issue, thanks a ton! But now we're seeing some weirdness where the geo-location for users on corporate VPNs is totally off, like it's showing them in a data center thousands of miles away instead of their actual city...
