I also am using a HP G72 laptop using the following built in adapter: Realtek RTL8191SE 802.11b/g/n WiFi Adapter
My issue is when I reboot my router the notebook sync's up at 150mbit/sec which is the routers max. After about a day or 2 it winds up dropping down to 65mbit/sec. I am curious how I can or if i can get it to stay at 150.
I have security set to WPA2-PSK [AES] And channel is set to "AUTO"
