Hi guy i need some help yesterday i try to update my ESS 4 to ESS 5 but not success in the first time. it said there are ERROR and do not have enough privilege to change the setting. so i cancel the installation. I try to uninstall the ESS 4 first. but the uninstall function of ESS 4 does not work. I Google and find that there is other way to uninstall it. i follow the guild in here kb.eset.com/esetkb/index?page=content&id=SOLN2289&ref=wsf It work and successfully uninstall ESS 4.0 However, the other issues come out. my network adapter drivers are broken down. none of my network connection work. i go to ipconfig and only show "Windows ip configure" the other network adapter details are gone. i try to use windows diagnostic process and examine my wireless network. it said. "windows couldn't automatically bind the IP protocol stack to the network adapter" i try to manually reinstall the Network drivers and they are installed successful but they cannot connect to the internet. i ping with 127.0.0.1 and the TTL=128 i really dont know what i can do now. can someone help me solve this problem.
