I'm using ZTE AC3633 cdma dongle which gives me internet over EVDO network. If I connect the dongle direct to the macbook pro its working fine, but sometimes signal drops and have to go out and fetch the signal. For this I thought If I use USB extension cable (1.5 meter) and hang the dongle outside my window then it picks up good signal and gives me good speeds. But unfortunately its not working as it keep on saying "Cable unplugged" and it stays in loop. But If I use the dongle with power adapter using the same cable then I can connect to dongle wifi. I have done some research and came to know might be voltage or current drop and not sure where its happening and what to do. If I use powered usb hub will it be okay for data?
Also I have got the cheap china made usb hub ripped off.But didn't check whether I can do modifications on it to use it for both power and data.
Please help me with this and advice me on devices that needs to be purchased to ovecome the problem.
