Help with home wireless networking

Hi All, I need soem suggestions on what product would be the best for me.

I have a netgear dg834gt connect to my broadband, i can connect my laptop fine via wireless no problems. But I want to connect some other devices upstairs that do/can not connect via wireless.

What would be the best product to use that I can connect to my netgear downstairs wirelessly and allow me to connect my devices upstairs via CAT5.

Thanks

Dan
