Mike otic make some good and cheap options. We use on of their wifi extenders. Capps marina wifi will never be good for streaming but works well for backups.

Thought I might add. I have a tablet that is wifi only. I travel a great deal and found a great app that has been very good at finding me a wifi signal. I found it on googleplay ... its called "wifi finder" by JiWire. Its directory has 144 country wifi signals I guess one would call it. Was in Phuket a few months back and had no problem finding connections. Cannot reccomend it more. It is free.
