This wireless adapter does support 802.11n, (there are a small number of laptop manufactures that can have this option disabled)
Usually if you run into the issue where you only get a steady 54Mb/s it is related to configuration, See two links below:
Data rate will not exceed 54 Mbps when WEP or TKIP encryption is configured
What are the recommended settings for 802.11n connectivity?
I hope this helps
Could you check if it's disabled when I post you the serialnr.?
I've bought this card seperately and did it in my notebook.
The serial is: TA: E78590-001, MAC: 00231435F560, Model: 622AGHRU
With the newest driver I've no option to enable the N standard. And when I try to start the
wlan card with the 6300er driver I've the option, may it connect not with the n standard...
Thanks for help
Note that we do not recommend, encourage nor support the installation/or upgrade of wireless adapters performed by anyone but the laptop manufacturer. Just because each wireless capable system needs to comply and stay compliant with a set of regulations, See Intel’s position in regards to this at the link below:
But to answer your question, from the information you posted it indicates that you have an 802.11a/b/g-only version designed for Russia.
For the model 622AGHRU, the first part stands for 6200 chip, AG means that it goes from 802.11a to 802.11g, the H for the physical size and RU for Russia.
I hope this helps,
someone is distributing this in Switzerland...
I'll informed my supplier.
