Hello, I travel on my job and frequent many hotels/motels and just about all of them offer wireless. Some offer an adapter that I use my ethernet connection and power the adapter by a USB port. Those work great. Most do not. Is there a universal one that is on the market that will work with all systems that is compact in a zippered case? I have been researching this for 2 hours and don't seem to get anywhere. Thanks in advance.
