Problem on older Dell desktop, Windows XP Home, SP3. Internet connection via Linksys Wireless-N Gigabit router. Has worked fine in the past and continues to work with other computers and devices in the house. After a malware attack (which seems to have been fixed, but maybe isn't) I cannot restore the internet connection. On the malware problem, I ran super antispyware, malware bytes, and combofix (twice). Combofix found and repaired a rootkit problem. Now my wireless signal is strong, but get a "limited or no connectivity" error message because "network did not assign a network address to the computer." Network connection details: IP Address 169.254.227.169; subnet mask 255.255.0.0. After clicking "Repair" I get "Windows could not finish repairing because the following action cannot be completed: Renewing your IP address." I have looked at various sites and blogs and tried a number of suggested fixes, including turning modem and router off and on, fixing winsock errors, running "ipconfig /renew" and other related commands, etc. Firewalls are disabled. TCP/IP is set set to obtain IP address and DNS server address automatically. When I try to access Windows Firewall settings I get error message "cannot be displayed because the associated service is not running." when I try to start the Windows Firewall/Internet Connection Sharing (ICS) service, Windows can't start it. I have now tried putting in a static IP address. This eliminates the "limited or no connectivity" problem but I still can't connect to the internet. Any help is much appreciated.
