# When Mains Networking Fails, Use Phone Wires

**[Hackaday](https://daily.dev/sources/hackaday)** · 1 min read · 0 upvotes · 0 comments

## Summary

A hacker repurposed legacy copper phone wiring in their home for Ethernet networking using specialized adapters. The article explores whether cheap powerline networking adapters could be modified to work over phone lines instead of electrical wiring, potentially offering a cost-effective alternative to commercial solutions. The approach leverages RF subcarrier technology similar to powerline networking but avoids the noise issues of electrical lines.
