Only text commands are going to be send from server to devices, so I don't need high speed, I need reliability. Has someone any experience with such a setup ? Would one recommend different wifi dongle (maybe more powerful), with different chipset? I have also tested: https://wikidevi.com/wiki/TP-LINK_TL-WN722N But according to this info (and my experience) http://geekofpassage.blogspot.com/2014/07/openwrt-ath9khtc-could-not-add-sta-to.html There is hardware limit on the number of devices that can be connected to AP. Any other hints? This whole setup is supposed to be installed in a bus (double decker), single server (AP) and wifi module for each seat. Best Regards Marek
