Synchronized with very low data rates

I have this WLAN stick now for almost two weeks. I would not buy it to me again. I would have sent him back the most, but the effort to send him back and choose a new and buying (and possibly annoy again) were not worth me the few euros.

First, let me summarize the advantages:
Conveniently +
+ Small law
+ Good packaging (there is no need machete to open)

Disadvantages outweigh However:
- Synchronizes with very low data rates
- Still reveals a supposedly very good signal strength, data rate and Verbindungsqaulität
- The driver could not be installed from the CD without additional software

Since I have decided consciously for an 802.11n-stick, I was particularly disappointed by the low data rates. My router is within sight and in about four meters. First, I have to stick plugged into the back of the computer, so that was the case between the router and the stick. Signal strength and link quality were loud the supplied software good (80% and 90%). The software also allegedly reported a good synchronization rate ('Speed: Tx: Rx 150 Mbps: 300'). The disillusionment followed only when you visit the web interface of the router. The drive synchronized with rates 5-86 Mbit / s and this changed constantly.

I was hoping for improvement and put the stick so in the front of the chassis. He was in direct line of sight to the router. Signal strength and link quality are increased (90% and 99%). The stick now synchronized with data rates 54-216 Mbit / s. Mostly with 108 or 162 Mbit / s. I can live with that. I think it is a pity that the 300-Mbit / s stick is far from well in nearly optimal conditions.

External factors over which the low Synchronisierugnsraten could be attributed, I have ruled. All other devices (laptops, TV) synchronize anywhere in your home stable with 300 MBit / s.
