I have a home network which is a mixture of wired and wireless. I have one computer which is not wireless capable, ie, needs an ethernet cable connection, which I want to move to a part of my house which is within range of my wireless router. I know I could use a wireless bridge to make that connection. However, further away from that location I get bad or no wireless connection to my WAP using other devices (laptop, iPhone).

Is there a device which will simultaneously act as a wireless bridge (wired connection) and wireless extender/expander? Basically, a WAP with ethernet cable connections which connects wirelessly to the main WAP and accepts wireless connections to pass on as well?

I hope that is clear, but maybe not. Anyway, any suggestions are greatly appreciated.
