Hello, I have a rather strange and very intermittent problem with my wireless adapter (built in). I am running Windows 7 X64 and have Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC. Sometimes my wireless connection will simply just drop but not to the wireless router, only to the internet. It is not an internet connectivity issue on the routers part as other machines in the network gain internet access fine and it happens at both work and home, and only with this machine. When this issue occurs running a tracert to www.google.com for instance doesnt even make it to my routers IP address, pinging returns no response. If I wait a while eventually the connection comes back, a quick way for me to resolve this is to disable the NIC and re-enable it, but sometimes it will just happen again shortly afterwards. Sometimes I can go for hours with no noticeable interruption, other times it will just happen several times in a short space of time. I am at a loss with what to do, I have updated the drivers to the latest version, uninstalled the wireless device, restarted the machine and reinstalled the device... I just dont know. If anyone is able to help me out Id appreciate it. Thank you Steve

Hi, This may be related to the network settings, how about wired connection? You can try to not use 802.1X authentication to check how it works: 1. Click Network and Internet, click Network and Sharing Center, and then click Manage network connections. 2. Right-click the network that you want to disable 802.1X authentication for, and then click Properties. 3. Click the Authentication tab, and then click to clear the Enable IEEE 802.1x authentication for this network check box, if it is selected. Hope it helps.

I might have solved this myself but dont know yet. I thought it might be due to me having Hamachi Logmein VPN software installed, so i uninstalled it - though why Windows 7 doesnt detect the internet connection sometimes rather than the VPN (which is not internet connected at its destination) i dont know. ill give it a test throughout the week, see if this has made a difference
