Applications can't connect, browser works fine.

post #1 of 16
Thread Starter 
Monday night, everything worked fine. Fast forward to Tuesday afternoon, I can access and browse the internet with FF, IE and Chrome, but most of my applications cannot connect. Steam, Eve Online, Mumble, Vent, etc. Computer had been running the whole time, nothing was downloaded or installed since then, no changes were manually made to anything. MSN Messenger and Eve-Mon (character monitor tool for Eve Online) are the only two programs that I have that seem to work.

I've tried disabling Windows Firewall and NOD32, I've triple checked that these applications and their ports are allowed through the Windows firewall (they were before, not sure why anything would have changed there). I've reset Windows Firewall and started from scratch as well, no luck. At this point I've just turned it off.

Computer, router and radio (I'm on wireless broadband service) have all been rebooted. Router has been reset to factory defaults and I even did a system restore to before I started having problems. So far no go.

I'm stumped.

Update:

Ran malwarebytes.com program, it found some stuff but didn't help.

Bypassed my router and connected straight to my radio, didn't help.

Installed Mumble and Steam on my fiance's laptop, connected it straight to the radio. Didn't help.

Called my ISP, he said that I have an excellent connection to his tower. Radio checks out fine, data is being sent and received. There were no changes made on his end when my problem started occurring.

He mentioned something about there being companies who track/monitor and sometimes interrupt people's connections due to pirating with P2P software, but he didn't see any sign of that happening with my radio. He did switch the routing of my radio through his tower and assigned my radio a new IP address, but that didn't help either.

I doubt this would be the problem, as I haven't used a P2P programs in a long time. I did have BitTorrent installed, but it was not running (in background or otherwise).

I'm going to try a fresh install of Windows, since I have no other ideas. But I doubt that will help either. So confused.

it might be the router. Have you tried connecting the Ethernet straight to the modem? Try it.

check ie's proxy settings.....

I know you don't even use IE, but sometimes it's settings are used in applications.

Also have you checked your hosts file C:\windows\system32\drivers\ect\hosts

Edit: another thing, some ISP modems have a firewall built in, connect directly and see if you are being assigned a local address by running the command prompt as admin and using ipconfig.

The only box checked under IE LAN settings is 'Automatically detect settings'.

The file is there, what do you mean by check it?

I'm not sure what I am looking for? I did this and it seems to show that I've been assigned an IPv6 and IPv4 address.

Hosts should only have one entry, which is 127.0.0.1 localhost. Unless you use a program that uses the hosts file to block adware.

Basically you are looking for a local IP address instead of your normal one. For example linksys is usually "192.168.1.1" mine actually is "192.168.15.100", If you get anything other than your external ip(ipchicken.com, whatismyip.com) then your modem has it's own firewall and needs to be bridged.

Usually your Internet wouldn't work at all but i have seen very strange setups where people have been running double nat.

How do I view the Hosts file?

Ok, connected directly to my radio/modem, ipconfig gives me an IP address of 169.255.1.200. According to the sites you listed my IP is [FONT=Verdana, Arial, Helvetica, sans-serif]216.123.234.101[/FONT]

I did a tracert with my router connected:

Trace complete.
The third jump has a similar IP address, would that be the router that may be blocking me?

One thing you could check is your anti virus and firewall. Turn it off and see if that's what is affecting your programs.

Very first thing I did, with no effect. Even if it was that, strange that it would just pick a random time to block all applications from accessing the internet.

Is it a static IP or dynamic?
