 The funny thing is, while in 802.11n only mode, my connection on the routers wireless status page still showed .11n.   Did you mean to say "my connection on the routers wireless status page still showed .11g."  ? I just found something interesting:  [URL] Also, make sure you have the latest firmware for your DIR-625.  Take a look at the webpage below and select the correct revision of your DIR-625.  I'm not sure if you have the REVC or non REVC version of the DIR-625.  The REVC version has a firmware that came out in March 2009.  The latest non REVC firmware mentions something about a fix for enhanced compatibility with Broadcom clients.  The Dell 1505 Wireless adapter is actually a Broadcom adapter.   It is possible that there is a defect with your router saying that the connection is 802.11g when it is actually 802.11n.  Perhaps D-Link has fixed the potential issue with a new version of firmware.  It's worth a try. [URL]  
Hi, I have an Inspiron 1525 that has the 1505 wireless 802.11n wireless minicard. I have no problem connecting to my wireless network but my router shows the connection as 802.11g instead of .11n. My router is the Dlink DIR-625 which is a 802.11n router, and the wireless network is shown to support .11n in the dell wireless WLAN Card Utility. The driver version on the 1505 NIC is 4.102.15.61 - Dec 19, 2006. I'm wondering if there is a setting or something to get it to use the .11n standard instead of .11g? In the Configuration options for the NIC there are options for .11b-g but doesn't mention .11n anywhere.  Any advice on getting it to use .11n?   Thanks, Scott
