Any WRT based model which can run OpenWRT should be able to do it. If you want off-the-shell/out-of-the-factory support, look at Yamaha NetVolante. D-Link should now also, like the WRT's be open as they where 'caught' using GPL stuff, thus they had to open up everything. Easiest seems to be the WRT's especially as they are proven to work and are available for some time. You can also always go for a old p75 + ethernet cards + wireless card ;)

thanks for fast answer Jeroen , i look at openwrt but the device that is good for me( Linksys WAG54G )is not in the list of compatibly devices , some suggestion?
