of purchase / order to delivery went just 1 day: very good on Amazon! Insert the Grundig USB dongle on TV, installs itself automatically finds the router (ID type) and off you go ...! it's really easy to accomplish :-) problems even for me as a layman technology. The price is not bad, but here probably Grundig has a monopoly ... whether an Ebay-Stick also works well? I want it not to try (who buys cheap, often paying twice). If the TV is too far away from the router, you can also plug a USB hub on the TV and ... extend in this way ... well, how shall I say quasi connection and so a better pres Special requests can for router reach. Anyway, I've done it so: USB hub (70cm cable length) plugged into the TV and adhesive tape on nem higher point glued (yes you can test where the reception is best). Here then plugged the dongle ... what can I say ... Top reception! So also a "very good" to the dongle manufacturers! My absolute buy recommendation
