Computers don't see each other / don't ping on LAN w DLink 614+

I have two computers set up with my 614+ router.
Both can access the internet and everything is working fine ... except that they don't see each other and I can't share files between them.
I can't even ping them.
One of them is connected wirelessly to the router and one by cable.
Both have IPs assigned to them and by all means it SHOULD work ... but nothing.
Do I need to chnage any firewall or Virtual Server settings?
 
Everything is set up correct and the two computers even have static IPs.
At least they should be able to pring each other.
And they can both go online fine ...
Just each other they can't see.

This is sooooooo frustrating
 
I didn't read the guide that someone posted earlier, so perhaps the suggestions I'm about to make were previously mentioned, my bad if they were...
-Make sure both computers are in the same workgroup
-Turn off firewalls if there are any (specifically on either comp on your network, not the dlink)
-Make sure you are typing in the full correct name...ie \\computername\sharedfoldername
-make sure when you define what folder(s) you are sharing out that you also set permissions to "everyone" ie mid page on this link
...also, as that link says when you specify "everyone" to have access to the share in the shared folder settings, that means everyone on that PC....this means that you should have the same users set up on both PC's (prob a good idea to have the same pw's as well)

Let me know how it goes buddy - cheers.
 
Can you ping the other machine by IP address? If not, you have some sort of firewall stopping the traffic, since you are connecting to the Internet properly.
 
No!!!! That is what I have been saying.
And both machines have fixed IPs!!!!
This isn't about wrong configurations and protocols.
I can't even PING!!!!!

Let's see if I understand.

Both machines can connect through the broadband router to the Internet.

Neither machine can ping the other, either by use of name or IP address.

The machines are on the same subnet.

The subnet mask is correctly specified.

The default gateway and DNS address point to the router.

I'd say you have firewall's configured blocking the pings, or your router's switch is broken.

WinXP firewall turned off. YES

Router firewall only configured for outside? I THINK SO.

Switch broken? HOW DO I CHECK?

And both have no problem accessing the internet at the same time (traffic comes and goes to/from both computers).
 
I'm having the exact same problem as you. The only difference is that I'm pretty sure I don't have defective hardware, because up until reinstalling the OS on both computers a few days ago, file sharing worked fine. Did you ever figure out your problem?
 
The only possibities for either of you appear to be either the switch in the router is not configured correctly and is blocking the ping requests, or some firewall is blocking the ping requests. There really isn't anything else in the mix that I can see.
 
Thanks for your reply both here and in my other thread, Gunrunner. I'll do some checking tonight after my kids get to sleep (which will be awhile since they'll be hopped up on Halloween sugar!) 😉
 
Are both your IPs public or private? Did you check the Windows XP built in firewall?

I've seen this problem when both of the IPs were public. Makes it much more difficult to make any kind of "private" LAN.

I'm afraid you're already over my head. How can I tell whether the IPs are public or private?
 
192.168.0.100 and 192.168.0.103
(router is 192.168.0.1)

I can ping the router but not the comps.

D-Link support is extremely stupid.
Here is their reply (after explaining in 20 emails what the problem is):

---
This is not possible. The router is not the cause of the problem. I have consulted with other techs and we've come to the conclusion that there may be a problem with the arp table on one/both of the computers.

The router does not have route tables that could be causing this.

Well, if it is not possible, WHY is it happening?????
 
Thanks gunrunnerjohn.
I will try that.

Great job dlink tech support. Telling me that you think this might be the problem but not telling me how to fix it.
 
The ARP enteries have a TTL (Time To Live), so they should be self-correcting, but you never know...

You know, you never did post the output of an IPCONFIG /ALL from a command prompt for the two machines in question. I'd be curious to see that.

You're correct. The addresses start with 192, and I am using a broadband router. Guess that's not the problem. I suspect that my problem is that ICF is turned on, but damned if the XP Help Procedure for even finding the option to turn it off is any help at all. It's as if it is referring to a different operating system.
 
<FONT face=Verdana size=1>weshuang</FONT>, if you have a broadband router, you most CERTAINLY don't want ICS enabled! That will totally confuse the network, small wonder you can't get connected!

Looks like your static IP's may be out of range of the current Router setting.

Try setting your IP's to 192.168.0.2 and 192.168.3

I use D-link products exclusively and never have problems.
