TP Link TL-WN722N working for G network, but not for N

Thu Aug 23, 2012 6:45 pm

Hi All,

I've finally got the wireless adapter TP-Link TL-WN722N working with my network.
It's able to connect to my G network, but I've had no success with my N network.

Has anyone had success with this device connecting to N networks?
It's working in Openelec/XBMC for G networks but cannot connect to N networks.

In Raspbian it shows any G networks that are available in the area, but again no N networks show.

Any help/suggestions would be great,
Thanks,
BtB.

USB is limited to 35 MB/s so you might find it pointless to attempt a 150 MB/s connection.
They might have omitted some drivers because of this.
G at 12 MB/s is probably plenty no?

...and 640K of memory should be enough for anyone.

Sorry, couldn't resist :D

Seriously, there are other advantages to using N networks over G, notably a *much* better range. Not that I can be of any help with getting it working, Linux noob that I am, but it is IMO certainly worth working on.

Thanks for the replies all.

I think I figured out what was happening...
I have a simultaneous dual band 2.4Ghz 5Ghz router and thought that the 5Ghz was required for the network to be N. I've found out that's not a requirement. So I'm pretty sure that the connection I thought was G was in fact N.

It's been working fine no matter what I've thrown at it with my network shares so it seems to be fine.
I'm not sure how I can 100% confirm that the connection is N on the Pi, but I've tested it with Wifi Analyser on Android and it's showing up the networks as N.

I'm guessing that the two adapters I've tried, although being N are not 5Ghz which is why I couldn't see my other network.

Thanks again all.
