| | Local Area Connection doesn't have a valid IP configuration I’m having intermittent network/internet problems on my dsl wired ethernet connection. Sometimes the internet works fine. Other times the internet is really slow or the network says unidentified network. I run the troubleshooter and it resets the local area connection adapter, giving the error that LAC didn’t have a valid IP configuration. But this fix doesn't seem to last more than a day or so. Also, downloads with windows firewall and/or zonealarm firewall on fail or are interrupted, but not when firewall is turned off. I’ve tried a clean install of Windows. Reinstalled drivers. Reset the modem. I tried ipconfig /renew. Nothing seems to work. Windows 7 home premium 64 bit Realtek RTL8111C Gigabit Ethernet All my drivers are updated.
