But many hotels don’t have a secure wireless network setup or you’re limited on using a single device at once. Investing in a portable, mini travel router is a great way to connect all of your devices at once while having total control over your own personalized wireless network. -A logical combination of AP+STA mode on one physical radio allows most of OpenWrt/LEDE supported router devices to connect to a wireless hotspot/station (STA) and provide a wireless access point (AP) from that hotspot at the same time. Downside of this solution: whenever the STA interface looses the connection it will go into an active scan cycle which renders the radio unusable for AP mode operation, therefore the AP is taken down if the STA looses its association. +A logical combination of AP+STA mode on one physical radio allows most of OpenWrt supported router devices to connect to a wireless hotspot/station (STA) and provide a wireless access point (AP) from that hotspot at the same time.
