We have an 891W wireless router on which we have enabled 802.11n speeds. When we connect with a 802.11n laptop client, it seems to be connecting on non-N data rates. We're trying to figure out if we've missed something in configuring the router or something that needs to be done on the client to make it connect on N speed. Any assistance would be greatly appreciated. Thanks.
Here's our show int command which shows that N is enabled on the radio:
wap-temp-rtr#sho int dot11Radio 0 Dot11Radio0 is up, line protocol is up Hardware is 802.11N 2.4GHz Radio, address is 0027.0df0.a730 (bia 0027.0df0.a730)
Here's the output of the show dot11 command that seems to indicate that the client is connecting on B/G speeds:
wap-temp-rtr#sho dot11 asso 0022.fbca.3a70 Address : 0022.fbca.3a70 Name : wap-temp-rtr IP Address : 10.1.10.41 Interface : Dot11Radio 0 Device : ccx-client Software Version : NONE CCX Version : 4 Client MFP : Off

Well... that client will never connect via 802.11N. The reason is that the 802.11N standard does not support tkip. So if you change the encryption to WPA2/AES or leave it open and make sure you channel bond (40mhz) channel width, then you might be able to connect using 802.11N. Hope this helps.
