Do you have any wifi adapter module or datasheet? The interfacing depends on what communication to use. UART, spi, I2C. pic16f877A and pic16F887 is commonly used, that enough to use UART, spi or I2C.
spi Communication between two pic 16f877
its simple to use serial interfce (USART). it need only two pins. if you don't know ablout the interfaces like serial, spi or I2C. connect any IO port of the two ICS and transfer data as your using it for a switch or LED. which c compiler you are using.

you can use the pic16f877 and c.i 74ls595 wich is a converter spi, you can use many of this c.i are very interesting
I can not comunicate 2 16f877 in spi mode; Is there any one whit an example working. Tanks in advance.
Here's my version of universal board: all ports on separate 10-pin headers with pull-ups/pull-downs (jumper), integrated max232 and USB connector, DC plug with 7805 and 4 multiplexed spi connectors and an ICSP (RJ12) plug. Board can be powered either from USB, DC plug or ICSP But, there are two design errors to fix: 1. DB9 connector was routed
I am afraid you can not extend the code memory of a pic 16f877. You could for example if you have lots of strings in your program put these strings in an external eeprom which can be acessed via I2C or spi bus. You would have to get the string whenever it is required from external EEPROM. I have no idea if your application allows this. (...)
