My adapter used to connect at higher speeds to my router, but no longer does. It connects at a maximum of G (54Mbps). Even though my router (Cisco Linksys E1000 running DD-WRT) is showing an average of 216 Mbps under its wireless status, my laptop will not connect any faster than 54. It is in close proximity to the router and shows EXCELLENT signal strength.
The only thing I show as confusing is when I go into the wireless adapter properties --> Advanced --> Wireless mode, it shows #6 802.11a/b/g but does not list N. But this adapter clearly supports N. Am I missing something here?

Update your drivers to the latest 16.11 from Intel. https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3502&DwnldID=23726&ProductFamily=Wire...

What the other laptop connects at may not be relevent.
If the access point is configured for AES + TKIP encryption and the subject laptop is configured for TKIP encryption, it will connect at no more than 54 Mbps.
The "other laptop" that connects at 144 Mbps may be configured for AES.
There is no simple answer. All relevent information needs to be tabled and considered.
To add another wrinkle, a number of draft 802.11n implimentations failed to honour the no more that 54 Mbps for TKIP.
So my question stands.
And so it goes.
