If you have time to help me solve this problem I would really appreciate it. First off, I have a Samsung NP350V4C notebook with an Atheros AR9485WB-EG Wireless Network Adapter (currently up-to-date), the system I'm running on is a Windows 7 Ultimate x64, and my router is a TP-Link WR-740n. As of now, I can connect to our router and internet nicely, but this is only possible because I just restarted our router. And probably (100% sure of it), if I restart, reboot, sleep my notebook, or simply press the disconnect button on my wireless connection list, I would have difficulty connecting again. By difficulty I mean, my notebook would continuously try to identify the network, and in between identifications says "no internet access" with a yellow triangle with an exclamation point on it. So, again I have to restart the router just so I could connect my notebook to get wireless connection. Troubleshooting the network (by clicking on the red "X" mark on the network map between the home network and internet) doesn't help either. I also tried the ipconfig /release and /renew... does not help either, it just says media disconnected and such. One thing that amazes me that my notebook can connect to my cousin's home wireless network flawlessly (they are just right next to our house). Anyone have any idea what I'm experiencing right now? I just can't bare the continuous cycle of resetting the router just so I could use the internet on my notebook.
