- USB charging for my tablet and smartphone (no need to bring extra power supply)
- AP Mode (to quickly build a wireless network)
- AP mode with Router (as before, but with NAT router)
- Client mode (if I want to integrate a PC into the wireless network that does not have wireless card)
- WISP mode (unit is also wireless client and AP with NAT router)
Particularly important is the WISP function that the smaller TP-Link 702N has not. Here you can z. B. received the Hotel-Fi and a new radio cell with a private address range set up The advantage of this solution is that you can use multiple devices use the hotel-Fi and have to pay only for a device. In recent Spain vacation I still missed the opportunity to join a UMTS stick to this unit since the week Internet cost 20 euros at the hotel (UMTS with a Spanish SIM card would have cost 10 euros). This feature is unfortunately not supported by the TP-Link firmware, although this device has the optimum conditions for this. I have therefore the alternative firmware OpenWRT installed on the TP-Link 710N, with the support UMTS is possible. That works wonderfully now with my UMTS stick Huawei E160, E173 and ZTE K3565-Z (Vodafone). Even my old Nokia 6220 classic cell phone I could integrate as UMTS modem. However, the installation of OpenWRT I would not recommend it for inexperienced users, as the device is something difficult and the equipment could be destroyed. Nevertheless, it is interesting, what is possible with OpenWRT. With 8 MB of flash memory of TP-Link 710N also has the optimum conditions for further experiments.
Next, I'm going to make a tag for an external antenna, so in my next vacation WLAN has a wider reach.
