I recently had Windows Protection Suite take me for a ride. I finally got that off the computer and thought I had gotten back to normal. However, I still can't connect to the internet. My incoming line goes to a cable modem, then to a wireless router and then to the computer. I have a laptop running off the same internet connection via the wireless router. The connection on the laptop is fine. I have even tried connecting directly from the cable modem to the computer but it won't find the connection. I checked in Device Manager and it says the networking card is working properly and it is enabled. I have tried going into Internet Options and trying to set up the connection manually but because the connection is always on, I don't need to set it up that way. The troubleshooting suggestion given by Windows are to make sure the internet connection options are set to automatic which they already are. Any suggestions on what I'm doing wrong? Thanks in advance.

you may need a wireless adapter for your computer depending on how old the comp is alot of older desktops don't have a wireless card built in like
laptops.you can try setting up a homegroup network.that is done control panel network options. it will ask you for a password which is on the
bottom of the router. should be an eigt digit number under the serial number. If that eight number doesn't work run the installation disk that came with the router and there should be a 32 letter and number password. LoL

Another small suggestion is to unplug the router then wait a few seconds then plug it back in then try to connect, I say this because sometimes malware may effect the router as well as the computer it was on, also be sure that the malware is gone. I would try this before doing the above.
