Need a little help here.
We have ATT Uverse for internet and TV. I also use the wireless to run my Xbox and Blueray player. The computer recently decided that it will not connect to the internet and is granted local access only. We tried all the reboots, switching the lines, switching the modem, and clearing all the files. ATT came out and did pretty much the same thing plus a little more advanced stuff and came to the conclusion that it had to be a virus. Wireless works fine, tv (which runs through the modem) works fine, just the computer will not connect. Even after we cleaned everything off, the network was granted local and internet access for a bit, but we still could not connect. Any ideas what type of virus this is and what I can do about it? |

little confused.
what is local access? you can see machines on your network, but cannot get to the internet only? what sites did you try to get to on the internet? can you ping internet sites? is this the only wired box you have? was a little confused. and it is going through the att modem? or do you have your own router? |

Yes, all I can get to is the machines on the network but no internet. There is a little box with the two computers in teh right hand lower corner that says something like "Connected to xxxxxx (whatever network) Access: local" normally it says "Local and Internet." I tried searching for a different network including using my phone as a hotspot and it won't pick anything else up. On one of the reboots, it did say "Connected to unidentified", but upon an additional reboot it when back to my network.
I tried a few different sites. Google, Yahoo, a few others and of course AR15 Tried pinging with yahoo and google with no luck. The computer is wired and the cable box I believe runs to it. Xbox and Blueray are wireless. They all work fine, just the computer giving me a hard time. Thanks. |

so first move it to a different port.
next see if the modem has something turned on to block access wired and not wireless, or if you have something turned on, like mac filtering or some ip issue. that is weird. to see the network, but not get internet. is not a normal virus thing either. |

I would try to reload your browser program. Delete it first. I had a wierd problem like this that conflicted between IE and Windows. Reloading the browser didn't really help me and I had to restor my HD from saved image and then reinstall the browser. I don't think a virus corrupted me, but all of the motherfucking upgrades that windows wants to install. |

It's highly likely that it's a virus. It probably has a proxy server implanted somewhere in your OS or has tampered with winsock (the network stack, if Windows) and changed some settings or enabled IPSec.
You should use this guide to help resolve the issues: http://www.selectrealsecurity.com/malware-removal-guide However, if it turns out that this doesn't help you at all and it's not a virus, it could be the way your network is set up. Do you plug the desktop directly into the access point? (Does it have a built in switch?) |

try a different network cable
try a different port on your router verify IE isn't set to connect to a proxyserver link open device manager, select your network card, uninstall it. restart the computer |

"granted local access only" usually means that the system didn't get a DHCP IP address from the router and windows has given itself and auto-config IP address, which is always on the wrong subnet.
When troubleshooting network problems like this start at the computers Ethernet card (ipconfig/all), did it get a valid IP address from the DHCP server in the router? If not hard code one then enter the router's Ip address in Chrome or IE and see whats up with it. Follow along to the cable or dsl modem if you need to. Every now and then comcast's DNS goes TU and I'll get calls about "granted local access only", I'm sure ATT has similar problems. |

If I uninstall it, how do I reinstall? I've tried everything on this page so far (except the post just above mine from pdg45acp because I just saw it) and the best luck so far has been running the www.selectrealsecurity.com protocol for removal of virus' and malware. It didn't fix it, although now it says I'm connected to local and internet, but still won't connect. It did remove a ton of adware and malware too. Since the wireless is working, would it be worth it to try to connect the PC wirelessly? Could one of the ports be bad or something? I'm also thinking of taking it to my brothers house to see if it will work on his network just to double check that it's not that. Thanks for the responses so far guys, I appreciate it! |

Thanks all,
It's fixed. I'm not sure exactly what I did that fixed it, but I used ipconfig/flushdns, ipconfig/release, and ipconfig/renew. renew did not work and said I was not connected to teh server. I went and check the network properties again and the IPv6 was checked for some reason (never had been before), unchecked that with no luck. Then, as I was thinking of what else to do, the Mcafee program that we had kept popping up telling me it was out of date (we don't use it anymore, we use Microsoft Security Essentials now). It was getting very annoying so I went in an uninsalled it since we don't use it. Just after I hit uninstall, the little connection icon down in the corner lit up - Local Acces and Internet. Works fine now. I have no idea which one of these made it start working again, but it does. Thank you for the assistance! |
