|This problem has defied all attempts by some half-dozen people, including multiple trained tech support guys (from the States, not foreigners). I've spent some time looking through forums and Google, no luck. I hope somebody here can help!|
Wireless router. Multiple computers on the network, some desktop and some laptop, plus a cell phone and PSP. Only one desktop doesn't work. Computers are using Vista and XP, problem computer is using Vista.
HP desktop purchased at Best Buy just over a year ago. Full memory upgrade, 400+ GB hard drive, the works. Zonet Wireless 8185 card is the only addition to the stock model.
Windows Vista 32 bit. Fully updated as of a few months ago.
NO Anti-Virus, firewall, or other similar programs installed.
Shows full connection to wireless network, full bars. Unable to access anything through browsers (IExplorer or Firefox). Unable to ping outside address (like google.com)
What we've tried:
Computer connected to internet in Idaho, family moved to South Dakota and got a new internet provider. The other computers switched over just fine, this one wouldn't connect at all.
Tinkered around with settings, found TCP/IP 4 wasn't activated. Clicked it on, double checked other settings to find them correct. Renewed IP addresses, got one, but it was a 169. However, the computer finally recognized the network as existing. Connected with limited access only.
Checked password for accuracy, reset router settings from computer. Reset router by unplugging power, waiting, plugging in. Renewed IP address. Disabled Windows firewall. Used three different drivers for Zonet card. Computer still only connected with limited access only.
Called tech support (the internet provider; HP won't provide support because it's out of warranty by 3 months). They verified our password as correct, verified that there were no problems on their end. Verified that the account was set up for 10 simultaneous connections, removing the possibility of us overloading the account with the six other devices accessing it.
Tech guy disabled router firewall. Used netsh commands to reset IPs and all that jazz. We verified other settings for accuracy. Tried to ping google.com from cmd and got nothing.
Restarted in Safe Mode with network access. Same results; Windows says it's connected, but no packets are received, can't ping out, nothing can get through.
Attempted to force manual IP and DNS selections. Using IP provided by tech guy, entering into Network status -> TCP/IPv6 -> Properties -> Manual selection, we got the error that it was an "invalid address". What?
After the few hours with tech support, it said we were fully connected, but still couldn't get anything through. Ended tech support call. Uninstalled network card, swapped with totally different card. Installed, same results: "full connection" without any actual access. Reinstalled original card, sat down and cried.
Okay, didn't really cry. But yeah. We tried every suggestion through Windows "diagnose" pop-ups. Looked online for help, found some stuff on MAC addresses, tried that and locked down the whole network. Had to call tech support again, had them reset router settings to undo my mistake. Asked this tech support guy for suggestions, swapped ideas, ended up with the same stuff the first guy had thought up.
It seriously seems like something is blocking the connection, like a mystery firewall somewhere. But there isn't an anti-virus installed, nor another firewall, and nothing else should load up in safe mode...
So, does anyone have any ideas? None are too simple, none are too complicated. I want to hear them all.
