Sometimes when scanning emerged briefly the 2.4 GHz Link of C9 on, if you're lucky and responds quickly connects the T2U with him, and if that succeeds, the connection also good, stable and fast.
The 5GHz band of C9 is the T2U but never!
Not even with the latest drivers.
Another disturbing aspect is that there is in the reviews of V2.0 from 2010 talk, my T2U is however reported as V1.0, so actually he would have to be put on the market before 2010, could be so on the idea come here as would "bundle" a lot of old sticks disposed of, but speaks against this theory is that the T2U on the box as "Windows 8 compatible" is specified, Windows 8, however, only in mid-2012 was released .. However, of course could also just an old stick have been packaged in a new box.
It does not matter for me the adapter is almost useless, I do not have a 10 minute wait if he might find my router normally the time.
