on pi zero for pihole where I used it as an ethernet adapter it had connection issues and kept flapping continuously.

Worked immediately on Xiaomi TV Stick (TV STICK MI 4K UHD PFJ4122EU) where I was having a problem with 2.4GHz WiFi (100 Mbps line and it was connecting with just 3 Mbps half a meter from the router). It worked immediately on the wired network without needing any configuration from my side, and now it connects at 100 Mbps.

I have the old black Google Chromecast.
For many years it worked flawlessly, but something happened and it started disconnecting wildly.

I tried everything, I brought an access point within breathing distance, nothing, no stable connection. I changed the access points, reset everything, until I even installed fiber optics, changed the router, nothing... :-)

I installed this adapter 3-4 days ago, of course, I reset the Chromecast and reconnected it via ethernet to the access point I placed next to it, we're talking about a super stable connection, not a single disconnection, while with the WiFi which I reiterate worked flawlessly for years, recently it would kick me out every 10 minutes and restart the Chromecast.

Essentially, it's still using WiFi, because the ethernet cable isn't directly connected to the router, but something must have happened to the WiFi receiver of the Chromecast...

Now everything works great!

I have installed it on a Fire TV Stick, and I get the speed that the cable provides me, while before with WiFi, due to not getting a good signal, it didn't have speed and good image resolution

I connected it to the Google Home Mini to have Ethernet and it works perfectly. However, be careful as an additional adapter from USB A male to USB micro female is needed, otherwise it won't be able to receive power.

Those who are clueless and don't know what's going on with technology are kindly requested not to leave reviews. They should open their minds to learn something; otherwise, they shouldn't leave negative reviews on products misleading others because they themselves are useless at operating something so simple

I shopped... the connection did not happen.... NOT for this specific ONE FOR ALL TYPES... if you do not have access to technical connection do not wait.

Connected to convert a Xiaomi TV Stick 4K from WiFi to wired. Worked instantly without any issues, excellent.

WARNING!!!!

It does not fit this Chromecast:

because this specific ugreen is micro usb while this chromecast has a Type-C port. Completely incompatible.
Obviously, there has been a hardware upgrade.

Simply perfect. Connected to Xiaomi Mi Tv Stick 4k without any installation, it was recognized immediately. No lags or disconnections. For those looking for a solution for Tv Sticks, Boxes, it's here.

I have bought 2,
1 for my speakers (Google Chrome Audio)
and
1 for the Google Chrome Cast in the kids' room.
Both are excellent, 0 disconnects and no interference. 5 stars

I connected it with Chromecast Audio. It works fine. It would be better, of course, if it was offered together with the adapter to plug it into the socket, so you don't have to search separately to find one. And even more appropriate would be if the adapter was low noise, given its intended use.
