I sometimes come to work at AU BON PAIN, JAS URBAN, Srinakarin. I'm so happy when you have AIS WIFI for AIS users. But unfortunately, I found out that your WIFI is unstable. This is not the first time I found this issue with your WIFI.
So if you could come and check, that would be nice. Because I assume that, the AIS WIFI should be around AU BON PAIN area because on my laptop shows full wifi signal of AIS SUPER WIFI.
Hope you come to fix it, I don't want any AIS Users to get pissed with unstable WIFI when they use AIS WIFI
