Linksys wrt54gl and arduino uno.

Is it possible to connect arduino uno to Linksys wrt54gl directly?

Sure;-

load openwrt into it.

It provides two TTL serial ports at 3.3V level. The 5.0 to 3.3V level convertor is needed. Could connect 2 Arduino same time. kill two birds with one stone.

Add usb port if you prefer.

so i dont need max232 ic..can u tell me hw to!

The TTL serial lines on the WRT54G are 3.3V logic. The TTL serial on Uno is 5V logic. It would be smart to do level conversion between the 2 devices.
