The TP-Link AX1500 in Access Point mode works well but has three issues that would prevent me from buying more of them. I have two of the devices. They did improve the coverage in my house and they do permit iPhones to reach speeds of 600mbps on a gigabit Internet connection so for the price the performance is pretty good when they work.
Issue 1: The device seems to have a temperature problem that causes random crash reboots unless it is installed with cooling in mind. TP-Link has tried at least one beta firmware that did not fix it. Mounting the device vertically with plenty of air space around it and preferably with a fan on it has stopped the random reboots for me. TP-Link replaced my unit once but it did not fix it. Replacement shipping was my responsibility so it is really not worth the $20 shipping on a $70 device when it does not even fix the problem. My units are hardware version 1.
Issue 2: The device requests a DHCP address every 30 seconds, ignoring the DHCP lease in the delivered address. TP-Link considers this a feature. This "feature" is annoying and fills the log files on a legitimate DHCP server.
Issue 3: The last issue is that in static IP address mode it repeatedly resolves a few DNS names as a method to determine if the "Internet is available". The DNS servers in static IP mode are not configurable. TP-Link has hard coded the network router as the DNS server. If your network does not use the router as a DNS server, it will fail the test and turn on the red LED on the device.
I cannot recommend these TP-Link devices. Looking past the temperature issue, the way they ignore DHCP standards and add features like "Internet Available" that are needlessly doing DNS queries, makes me leery of any of their WiFi or routing products.
The TP-Link POE10R PoE Splitter does work with the AX1500.
