Well, I consider myself: The antenna looks through the "thick" design very chic, adheres to magnetic heating, etc., is stable thanks to heavy foot. However, the increase in performance compared to the wireless antenna to the PCI card is rather low. One with "only 5dBi" marked antenna (D-Link ANT24-0501 Indoor antenna 5dBi, IEEE 802.11b / g, RP-SMA connector, 1.5m cable wireless LAN) in direct comparison showed a major increase in performance. Okay, it costs three times, but if the wireless is really walk through walls, I'd rather pay 25 instead of 10 Euro and have no trouble with crashes ... although I was always satisfied with TP-Link products otherwise. Conclusion: Dear 25 euros Ordinary invest in what.
