How many days were you in Singapore? Probably the best way for a traveler to get a solid unwired connection would be to buy a new phone (unless you're lucky enough to already have a device with compatible LTE bands) and then enjoy the wonders of prepaid LTE and tether ($7/week/GB).
Maybe it is just because most people haven't upgraded yet, but I have a 4G connection over 90% of the time on my phone (with good latency) and I can't remember a speed test under 10 Mbps down (20-40 typical). It's good enough that it takes my home WiFi (backed 200 Mbps fiber) working near-perfectly on the 5GHz band to beat it.
