I need a recommendation for a reliable software, available and serviced & supported here in Thailand / Pattaya to support/run an existing system with 20 AP's.

Also possible a tech-company for installing and support. Thank you. MS>

For cheap and cheerful, and it works you can setup a Hotspot network using any DD-WRT router it's a standard option and gives you options to use several suppliers to use. here's a useful tutorial which may help:

Thank GinBoy.

I need a prof. system for a large hotel. Exisisting software monthly problems. O.c. Thai-made :-)...Any ideas...We got 20 + hot-spots & 30-40 users average at any time....Thanks and MERRY CHRISTMAS. MS>

Hotspot and ticket system on higher models of Mikrotik routers will handle this load just fine without any "providers". The only maintenance you will need is monthly database cleanup. Mikrotik implementation is very simple and lacks bells and whistles, but works amazingly well. DD-WRT is absolutely not suitable for what you want to do.

That model should be enough:

Buy two and keep one as a spare

I also hope your existing hotspots are not home-grade access points...

The Zyxel G4100 has meshed access points and front of house ticketing system, used it a few years ago, works real well.

monowall (mono.ch) has a pretty good captive portal system and wifi paid-for ticket system and best of all it's free..

You won't get any support though.
