Hello,
Not sure where the issue lies so posted on both DIR-655 and DSM-750 forums.
Anyway, I have DIR-655 fm 1.20 which I am very happy with so far. I recently purchased DSM-750 wireless media center extension with I am using in media lounge for now. The setup connection worked fine. Then at some point I went to DIR-655 configuration STATUS > WIRELESS and noticed that DSM-750 is listed as a wireless client and having its Mode as 802.11g. I was really hopping for a new wireless N connection as both DIR-655 and DSM-750 support that. I did check my wireless network settings on DIR-655 and it’s as follows:
802.11 MODE: Mixed 802.11n, 802.11g, 802.11b
Enable Auto Channel Scan: On
Wireless Channel: 2.437 GHz - CH 6
Channel Width: Auto 20/40 MHz
I do have other 802.11g active clients (Dell laptop) not sure if it matters.
Please help.
Thanks

That's why.

So, if I understand this correctly, when my notebook computer (which always uses "g" connections) is active and using the wireless connection at the same time the DSM-750 is being used, the wireless output of the router will be "g" and not "n" until the notebook computer is turned off, at which point, the speed of the DSM-750 will automatically be upgraded to "n" speed.

Yes. If your router is capable of 802.11n, and you connect a device using 802.11g, it will only operate on 802.11g. And from what I understand, it may not automatically revert back to N. You may need to power cycle the router.

This link (http://en.wikipedia.org/wiki/IEEE_802.11n) explains the way 802.11n and 802.11g are supposed to interoperate. It's not supposed to be as extreme as disabling all 802.11n transmission when there is an a/b/g device in the network.

This is incorrect and if users are experiencing this, you should consider it a bug.
From: Atheros XSPAN Technical FAQ (http://www.atheros-xspan.com/index.php?page=Technology&sub=Technical+FAQ)
- Q: What type of performance should users expect in mixed mode environments?
- Scenario Two : The access point is based on 802.11n and there are one or more 802.11n clients, and one or more 802.11g clients.
The access point will communicate in 802.11n to the 802.11n clients; the access point will speak 802.11g to the 802.11g clients. The devices should deliver the performance expected from 802.11n and 802.11g, respectively.

IDEA #1: When you set up the DSM-750, you had an 802.11g access point or the DIR-655 set up in a mode that didn't allow 802.11n.
Try the following:
(Note, I don't have a DSM-750, so you'll have to figure out how to do this.)
1. In the DSM-750, erase the currently saved wireless settings
2. Restart the DSM-750
3. Reassociate with the DIR-655 (as you would with any new network) and configure it correctly
Now check to see if you have an 802.11n connection?
If this helps, it's possible that the stored wireless network profile kept by the DSM-750 not only stores the security and connection parameters for the network, but also stores what communication mode (ABGN) to use (unusual in my experience, but perhaps results in faster connections). By following the above process, you have erased that profile and created one that stores the 802.11n capability of your current wireless network.
IDEA #2: You are not broadcasting your SSID using the DIR-655, and even though you did the steps in Idea #1, the DSM-750 first probes for 802.11g networks.
If this is the cause, I would guess it is a bug, probably in the DSM-750. Even though it should work correctly, not broadcasting your SSID is a bad idea on many levels and it is no form of security (it's a little bit like protecting your house from burglars by turning off the porch light or hiding the street address numbers).
To work around the issue, configure your network to broadcast the SSID, then repeat the same steps I recommended in idea #1 (as you have just changed the networking parameters).
Please post back and let us know if either of these ideas work out.

Great advice. Also try updating the DSM-750 to firmware 1.02 which was just released this alone may resolve your issue with your wireless connection.
