windows 7 - LAN can connect with computer name but not with IP
2014-04
Steve
I've got a small office network, about 20 machines, that all use Windows 7, and the problem described in the title.
Computer TM (the troublemaker) wants to talk to Computer FS (a file server), but it will only do so through the name COMPUTER-FS. An IP address won't work.
The facts:
- FS can ping TM with IP
- TM can not ping FS with IP
- TM and FS can both ping eachother using names
- All the other machines work as expected
In a possibly related issue, when users open the Network explorer, only a couple of the machines are visible. Sometimes they're all visible, sometimes not. This problem has been occurring for several weeks; the ping problem just started today.
How can I troubleshoot this and have TM be able to ping FS using an IP?
EDIT here's the ipconfig /all of Troublemaker:

When you ping by name, are you getting the ipv6 address returned? Vista and above have this enabled by default, so you don't need an ipv4 network set up correctly to connect.
What are the ipv4 settings? Are they in the same network range, with a proper subnet mask?

Here's my problem. I have a Netgear WGR614v6 wireless router and was able to set up the wireless network (I can send documents to my printer wirelessly), but I cannot connect to the Internet through the router. I have no problems when I connect the computer directly to the modem. When I attempt to connect through the router both wirelessly and by the Ethernet cable I have no Internet access. My wireless connection status says there is no IPv4 nor IPv6 internet access. Both are set to obtain an IP and DNS Server address automatically. Signal quality on the wireless router is excellent. I have tried power-cycling the router and modem with no luck.
This is what I have when I did ipconfig /all:

The first day I set up the router I was able to get Internet wireless and by Ethernet through the router. But since then (2 weeks) I've been having this problem. I am using Windows 7. Any help would be much appreciated.

Try completely resetting the router, i.e. hold any reset button down for 30 seconds, or log into the management interface and use any "Reset to Default"-like options.
As far as taking an actual look at your issue, it might be a DNS issue. Check to be sure your getting the right DNS servers via DHCP and that they are reachable. Alternatively, you can try disabling ipv6 if you don't need it.

Try updating the firmware on the router

I suspect it is, as @ultrasawblade noted, a DNS issue - try going to http://74.125.95.105 and if you get Google, you need to add your DNS servers to your router. DNS is the system that allows you to resolve domain names to IP addresses. There are lots of free public DNS servers - most ISPs have their own, but some popular ones can be found here: http://theos.in/windows-xp/free-fast-public-dns-server-list/

First off, I've had terrible luck with NetGear Routers, and would highly recommend not using them. With that said however, try following these steps:
Unplug the power cords completely from both the router and the cable modem (Leave the cable and CAT5 cables connected.
Plug back in the cable modem and wait for ALL connections to be initiated (at least 2 mins)
Plug back in the Router and wait for ALL connection to be initiated
Try your internet connection
This was the process that I had to go through on a regular basis with my old netgear router.
If this doesn't work, then I suggest borrowing or purchasing a new router to test and see if the issue really is the router. Other things to try is changing and double checking the CAT5 cables connecting the router and the modem. They do get used and over time can be broken. (Although I doubt this is the issue)

Okay, I FINALLY got it to work. What I did was I went into the Router Manager and completely reset it as ultrasawblade suggested. I had tried this previously and it did not work. However, this time around I did not go through the initial set up and left all the settings as is, with the exception of changing the security settings. Not sure what was different, but it did the trick. Thanks everyone.
