i had time warner cable add cable tv and internet to my house. (I previously used a CLEAR mobile device to access the internet). I am running Windows 7 Home Premium, I have a NetGear 600 Wireless router. The installation tech attached a cable from the modem to my wireless router. My computer says I am connected to the internet but I have "no internet access". I CAN connect through the CLEAR device but the performance is uncharacteristically slow. I should also add, when I attempt to run the "troubleshooter" to allow the computer to diagnose the issue, the troubleshooter will not "run". It says "an error has occurred". There is an error code that pops up whem I attempt to access a variety of applications (troubleshooter, antivirus software) it says <insert applicable program name> followed by "0xc000007b (for instance: AvastUI.exe - 0x000007b) Please help!!! Thank you in advance!
