I am stuck! Also I apologize in advance if this is not in the right forum. I am trying to work on a friend's Windows 7 desktop PC (Dell Inspiron) at my house, but I cannot connect to my home network or the internet to download malware scanners/removal tools, updates to MBAM, etc. First I was trying with a wireless adapter that it known to be good. The network sharing center would say it was connected to the network, but there was no internet connection. Then I tried plugging in an Ethernet cable. The network sharing center just kept saying "searching for network" but never would connect. I tried disabling then re-enabling the network adaptor, and I reinstalled the driver. Networking is not my strong suit, so is there some setting I may be overlooking? It appears the PC on which I am working is already part of a homegroup; do I need to leave that group then try to join my existing one set up through my own Win& PC? I don't care about sharing files across the network (in fact I prefer not to in case this thing really is infected); I just want internet access on this machine. Could some sort of malware be blocking access? I sort of doubt this since it was working fine at their home before they brought it to me. I could not find any router settings or firewall entries that appeared to be blocking access (ZyXEL PK5001Z DSL modem/router provided by CenturyLink). Do I need to call my ISP tomorrow? Thanks again; this community has always been helpful to me!
