Thanks and maybe for a laptop, and $10 at Amazon, but pretty basic it seems and only 2.4GHz band,
and I think one like this USB 3.0 2.4GHz/5GHz Dual Band 5dBi High Gain Antenna Network Adapter for that price would be better - if Linux even detects it: says "compatible with Windows XP/7/8/10/2000/Vista, Linux2.6.18-4.5 ('not develop version')" . 
However, seeing as I already have 3 adapters and do not want to spend more $ on such an old rig, then I removed the internal PCi-e Express Qualcomm Atheros AR938x Wireless Network Adapter from the main rig and put it in the old 755 that I was trying Linux on and it recognized and connected with it. I then install Kubuntu on a partition of a SSD (W7 is still on the HDD that I unplugged). I plan to try the Linux special sudo sudo git clone cd chmod sudo sudo work around for at least one of the others. .
