One of the computers on my network (wired) will not connect to the internet. I've had the problem for about a week, before which it was working fine. I made no configuration changes that I know of (although the computer is used by a "cupholder" type).

 

The other devices, both wired and wireless, can connect fine. The networking icon shows no problem, and I don't get any error messages when trying to load a page. However, web pages just show as connecting forever. The windows diagnostic (troubleshoot problems) is similar - it just sits at the "Detecting problems" stage indefinitely. Device manager shows no errors.

 

Windows system log shows 2 types of messages marked as "Warning":

1. TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available ports to be used and forcing the TCP/IP to reuse a local port for an outgoing connection. To minimize the risk of data corruption, the TCP/IP standard requires a minimum time period to elapse between successive connections from a given local endpoint to a given remote endpoint.

2. Name resolution for the name >this part varies between messages< timed out after none of the configured DNS servers responded.

 

I checked in the details for my ethernet adapter (Killer e2200 Gigabit), found through the network and sharing center, and the IPv4 DNS server is 192.168.1.1.  The IPv4 WINS Server is empty, if that matters.

 

I'm running windows 10 with AVG for security. Router is Linksys. ISP is TimeWarner (ugh). Computer is an older desktop, strong for it's time, but aging.

By the way, I know enough to find some of this info, but I'm not really sure what it all means beyond a very superficial level.

 

If anyone can offer any help, I would appreciate it. If you need any more info to diagnose the problem, let me know and I'll dig up what I can. (Instructions welcome, since my knowledge is spotty.)

 

Thanks!
