| + | ===== Installation ===== | ||
| + | |||
| + | Installation involves replacing the manufacturer' | ||
| + | |||
| + | The bootloader will be replaced with a custom Redboot bootloader. | ||
| + | The OS you have to compile yourself :-). The WRV54G does not work with the stock builds avaible. | ||
| + | |||
| + | To replace the original firmware you have three options: | ||
| + | - Telnet (requires fw 2.03) | ||
| + | - Serial (requires soldering) | ||
| + | - JTAG (requires soldering) | ||
| + | |||
| + | Telnet was disabled with firmware 2.10 and higer. Downgrade first. Simple feed te upgrade page from the web interface the older firmware. [[http:// | ||
