I'm trying to extract this firmware but I'm running into some issues. The first lecture of the firmware with binwalk shows this:DECIMAL     HEX

I copied the firmware from that position to the end but the new file is not recognized and the binwalk lecture is the same as above.

The LZMA compression identified by binwalk is correct (or at least most of them are - I didn't check them all). If you actually extract and decompress the LZMA files, you'll find that the first one (at offset 0x30) contains the device's code (a MIPS RTOS of some sort) and the rest appear to be the HTML files for the web interface.
