Dear all, I'm renting a ondo in BTS Ari. WIFI in condo is very weak, as the rooter located floor down. Is there any WIFI networks that I can purchase pre-paid card and use it in my condo flat? I work mostly from home, on-line, so the speed and coverage signal is important. Where I am from, there is a network called Kewico, signal covers strong everywhere in the city. We just buy pre-paid card and use it with smart phones, tablets, laptops and PCs with wireless receiver. Anything like that in Bangkok? Thanks in advance.
