The cost of an Ethernet shield for an Arduino isn’t horrible; generally between $17 and $32 depending on which one you buy. But have you seen the cost of a WiFi shield? Those are running North of $70! [Martin Melchior] has a solution that provides your choice of Ethernet or WiFi at a low-cost and it’ll work for most applications. He’s using a WiFi router as an Arduino Internet shield.

This is the TP-Link WR703N which has been very popular with hackers because of its combination of low price (easy to find at $25 or less) and many features: the USB is super hand and, well, it’s a WiFi router! The Arduino Pro Mini shown dead-bug style is talking to the router using its serial port. [Martin] wires a pin socket to the router, which makes the rest of assembly as easy as plugging the two together. The rest of his post deals with handling bi-directional communications with Arduino code.

If you really just need that direct Ethernet pipe consider building an ENC28J60 chip into your designs.
