Thanks for the answer, looks promising I'll try, we'll see what comes out. Yes, I suspected that this problem was the result of Samsung's deliberate treatment - ugly practice, Apple-style play.
I read the page linked at the beginning of this topic (on SamyGO) and maybe I could handle it, but a bit too much effort. Maybe today these devices from Allegro are 100% "plug & play"? I mean, I plug it in and it works, I don't have to change the firmware, PIDs, drivers, etc.
I would prefer not to update the firmware on TV, because the one that I have (from 2010) is praised by the most people, and in the newer ones they allegedly spoiled more and more things, blocked and removed options.
Or maybe a better option will be a router, eg TP-Link TL-WR702N in AP Client mode? Or Air Live N.MINI? The TV is a dozen or so meters away from the router and there are walls on the way, so such a USB card may no longer catch, and the router should. My main router is TP-Link TD-W8960N.
I bought the TP-LINK TL-WR710N nano router, which is practically the same device as you propose. Nice gadget but with my Samsung TV in AP client mode it does not work - I wasted many hours and failed to get the TV to work together. In general, Samsung discouraged me from using its products - the amount of work they put into making life difficult for users of their equipment by various limitations is impressive.
I have the original Samsung WIS09ABGNX / XEC 2009 wifi adapter - I've been using it for 5 years. He's a bit fickle about signal strength, but of course it works.
@Hermes: PLC - this is some alternative idea to wifi in this case. The only question is about Samsung TV - I have the impression that it does not like to work with "strange" solutions.
The discussion revolves around finding affordable WiFi adapter options for the Samsung UE40EH5300 TV. Users recommend several alternatives, including the D-Link DWA-140, TP-LINK TL-WA500G, TL-WR702N, and other models that can be configured in client mode to connect the TV to the internet via Ethernet. Some users express concerns about compatibility and performance, particularly with streaming video. The original Samsung adapters, WIS09ABGN and WIS12ABGNX, are also mentioned as reliable options. Users share experiences with various configurations and troubleshooting steps, highlighting the challenges of using non-Samsung devices and the importance of proper setup for successful connectivity.
