Dear Stefan and Z Ero, Thank you.
I do not live in the US and it is very hard to get old parts, because most of the sellers do to ship to where I live. I think I can live with the unstable wireless adapter for now. I probably should have spent less time on-line anyway. If I am too bothered with it, I will get a USB dongle, I think.
