TP-Link AC750 Wireless Portable Nano Travel Router(TL-WR902AC) - Support Multiple Modes, WiFi Router/Hotspot/Bridge/Range Extender/Access Point/Client Modes, Dual Band WiFi, 1 USB 2.0 Port

Can't remember getting it

Still don’t know how it should work!

I have the previous model of this, the TP-Link TL-WR702N (150mbps 802.11n-standard) as well as this one, the WR902AC (AC750). I don't do a lot of traveling, but got both devices for the flexibility of a small device that can be used as an access point, a bridge (repeater) or a router -- I've used both in all those modes.I specifically got this so I could use it as a repeater, to extend the reach of the 5GHz WiFi network of my main router in my previous apartment, where it worked fine -- there were no other 5GHz networks.I moved 6 months ago, and very quickly found out that this device, the WR902AC, does not support _ANY_ 5GHz WiFi channels above #48 -- specifically it does not support any of the high channels 148-165; this despite the fact that I bought the EU version of the device from Amazon Germany, and it has the EU version of the software -- and those channels are legal to use in Europe (as well as my country).Since I have a very noisy and crowded WiFi environment on both band ranges, the device is unusable; if I set my main router to choose its 5GHz channel automatically, it will always choose one of the higher channels since those are free of traffic & interference, and then the WR902AC won't connect to that network. If I force my router to choose one of the lower channels (and the usable ones change multiple times an hour), transmission rates are miserable (e.g., 7mbps, with a third of all web browser clicks yielding in a timeout), vs. the 234mbps I get with my main router.There are no available firmware upgrades, and the US-model version of the firmware refuses to install on this device.A router specifically advertised as a travel device should definitely allow change of geo region; even if it doesn't, it should definitely allow the channels legal in the region where it was bought.Still giving it two stars, because it may be a useful device for others, but for me it's become completely useless.
