Depending on the purpose for which you want to use this de facto mere WiFi "extender", it can be an ideal solution at a reasonable price, or it can also be broken. Definitely MP510 cannot be considered a full-fledged WiFi router or AP, the configuration options are minimal, basically just a MAC filter, some attempt at parental control (not really usable) and Guest network (it is usable). I bought it for my garden house/workshop, where WiFi from home can't reach, but where I have part of the data distribution solution using MP500 (i.e. the same powerline adapters, just without WiFi). The inability to set a static IP in the LAN I bypassed through static DHCP on the router. I have no complaints in terms of performance in relation to the parameters, rather the opposite. Yes, 5Ghz would be great, but for the price it's fine and in my workshop 2.4Ghz is enough. WiFi runs as expected from 2.4Ghz/40Mhz and due to the complex topology of the electrical network (25m from the MP500 connected in the house to the router, even 3 switchboards along the way) absolutely above expectations around 80Mbps+. So I have wireless coverage of the workshop and garden with speeds sufficient for 3 video streams in 4k quality without any problems. Otherwise, the first setting is a bit tricky. I already have 3xMP500 in my network, and adding MP510 was not without complications. 1. the first time I plugged in the adapter caught immediately, but it did not pair, the reason was quite funny - while the MP500 switches to pairing mode (the manual says "press the button for 1s") after a shorter (less than 1s) and longer (2-3s) button press, the MP510 needs only the shorter press, over 1s does not switch to pair mode. It took me about half an hour of debugging to figure it out. 2. when some changes are made to the settings - for me, for example, when changing static DHCP according to the MAC adapter on the router, turning WiFi Move off/on, changing SSID, etc. - it happened that the pairing with the source MP500 fell apart and I had to start again from resetting the adapters. But eventually it did and has been running perfectly fine ever since. I'll mention the WiFi Move function, it can be interesting for specific purposes. What does this function do? Well - if you have more than one of these powerline adapters, the ones where it's enabled makes it so that most of the changes in the settings (filters, wifi schedule, LED control, Guest network, etc. ) changes on one adapter are automatically written to all other MP510 adapters in your powerline network when saved. In fact, I'm strongly considering using this solution in my guesthouse, where I currently have 5 different wifi routers, 1 for home, 4 for guests, and managing them is sometimes annoying, especially when 3 of them are in forward mode, because there is no way to reasonably tighten the ethernet. So a powerline option for guests, where I could additionally easily extend the signal coverage (now missing for parts of the common areas, porch, etc. ) would be great. Unfortunately I haven't found the option to buy the MP510 separately, always just as a kit in a MP500+MP510 pair, which doesn't make sense (I would need one MP500 on the input from the main router and then ideally 5x MP510 for WiFi coverage. )
To sum up - for the purpose I needed to solve, this kit turned out to be actually an ideal solution with a great price-benefit ratio.
