Thread: I can't use port triggering!

ANSWERED / UNRESOLVED

Forum member Mp11 says that he has the Netgear WGR614 v6 and frequently uses the Xbox Live. Port triggering is supposed to work best with the Xbox Live, but Mp11 says that he gets port forwarding instead.

I have a Netgear WGR614 v6 router and I want to change my NAT to open so I can play with my friends on Xbox Live. It is at strict right now, how do I change it? I've can't seem to find it anywhere on my router settings page.

Have you consider enabling uPNP on your Netgear, if it is uPNP capable? uPNP is specifically designed to eliminate the need for port forwarding and/or triggering with uPNP enabled devices. This is a Microsoft standard and the Xbox is also from Microsoft.
 
  
 mp11
I did enable universal plug and play a while ago, and I didn't see any difference. Also, Xbox Live recommends that NAT should be open and not strict. I'll call Netgear once I get a chance.

Practically all SOHO routers are "open NAT," which means that they allowa all outgoing connections from the "inside" network. The bigger question is how effective/correct is their uPNP implementation, since you are trying to get another Microsoft product to work from inside a NAT network. Microsoft has released an online router test tool to help determine various SOHO/NAT router capabilities/attributes detailed here:

Thread: Inaccessible internet from one PC on network

ANSWERED / UNRESOLVED

This week in the forums our members assist Muppettry who has two PCs on a network, with a router hooked to a cable modem. After a cable modem change, PC#2 can see the 'net and PC#1 can't; but both PCs can see each other.

  
muppettry
This one's a bit of a mystery: I can't see anything similar in other threads but please point me to one if this has been seen before. This is my first post so please excuse (and correct) any breach of manners.

Summary: I have two PCs on a network, with a router hooked to a cable modem. After a cable modem change, PC#2 can see the 'net and PC#1 can't (the problem), but both can see each other. The router is set up to mimic PC#1. PC#1 can see the 'net if wired directly.

Deeper background: For a year or so I've had two PCs, both running XP, on a network wired (Ethernet) up to a NETGEAR FWG114P router. The router was connected to an NTL (now VirginMedia) cable set-top box (which had built-in
broadband modem). When I installed that, one of the PCs was originally wired directly to the set-top box to get the cable connection registered and so on; then I inserted the router between the PC and the set-top box, mimicked the MAC address, hooked in the second PC and both ran fine. I have since changed one of the PCs but it plugged back into the router fine, instant connectivity. No problems for a year.

I recently broke the cardinal rule of NTL/Virginmedia, which is DON'T EVER CHANGE ANYTHING, and got in a V+ set-top box. This (I found on installation day) comes without an internal broadband modem, so after a couple of broadband-free weeks I have had a broadband cable modem installed.

Based on all your collective information, it seems like built-in NIC on PC#1 and the Netgear may be running into "auto detect" line setting issues. The following thread may apply if this is the case:

Thanks for the suggestion. No joy on that.

The duff NIC is an NVIDIA nForce Networking Controller; on the Advanced tab in its properties dialog page it has 14 properties of which one is 'Speed/Duplex settings.' That was set to 'Full autonegotiation,' I have since tried 'Autonegotiate for 100FD' and 'Force 100FD', and tried combos of the half duplex and 10Mb/s settings as well. No signs of life.

However — possibly helpful peculiarity — at the moment (in a working configuration) my 'Network Connections' window shows only two LANs — the (duff, and now disconnected one, which I'm going to re-disable) and the new working one; there is no 'Internet Connection' icon. When I moved my Ethernet cable back across to the duff card for these tests, the 'Network Connections' window then showed an 'Internet Connection' icon (in the row above the two LAN connections). Odd that it shows that there's an internet connection present when there in fact isn't, but when it is actually connected there is no icon to say so. Does this make any sense?
 

  
 cszeto
Not sure where you are getting the "Internet Connection" icon with XP. It typically does not show any icon of that nature on a "stock" XP system, maybe it's from something else you have installed (e.g., software from your cable modem ISP service/package). If the original installation required any kind of software from your ISP, then it may be what you are facing.
 
  
 muppettry
Beats me — it was a fresh installation as I backed everything up and wiped the hard disk; reinstalled back from XP basic, up through Service Pack 2 and a hundred minor updates. Nothing else on there, haven't reinstall any antispyware at this time and the only firewall is Windows Firewall.

This icon seems to appear as a tease to suggest the connection might be working 'a bit.' As per one of my early notes, when the connection wasn't working, "if I go into that connection and disable Windows Firewall, then the Internet Connection suddenly reappears. It doesn't seem to make any difference to the lack of connectivity".

I'm still mystified. But thanks for the suggestions — I am now all working fine so solving the problem is more out of interest than out of need. Cheers!

Thread: Cannot Connect using Internet Explorer

ANSWERED / UNRESOLVED

In this PracticallyNetworked discussion several of our forum members discuss the new Windows Home Server (WHS), its benefits, online reviews, some issues they have encountered, plus add-ins for WHS.

I have a rather strange problem. I cannot connect to the Internet using Internet Explorer. My hardware is fine as shown in device manager, and my network connection shows I'm connected. I can receive virus updates and connect to my AIM IM and I can connect using IE if I boot into 'safe mode with networking.' Since I can connect using IE in safe mode I assume it's a driver problem. But how do I isolate it? I've uninstalled every non essential program I could but still no luck. Any ideas?
 
  
 JPnyc
What about firewall? Is iexplore.exe listed as safe? Did you check proxy settings?
 
  
 y2ken
I checked Windows Firewall and there wasn't an 'exception' listed for Internet Explorer so I added one. Still doesn't work. I installed FireFox just to see if it would connect and it works fine. I'm in the process of downloading (using Firefox)/reinstalling IE7 now.
 
  
 slashrose
I guess if you are able to go online in safe mode with networking, it surely is some third-party software. Rarely, I've seen issues with Windows Firewall causing the problem. My suggestion would be to check msconfig for the running services.

Run --> msconfig --> select "hide all microsoft services"

A list of all 3rd party services will be listed. Disable all of them, restart and check if you are able to go online in normal mode. If it works, then disable service one by one to find the culprit, kill it or configure it properly.

Repair IE if you're using IE7 by resetting all Internet settings.

Method to follow if you have Internet Explorer 7:

If you have Internet Explorer 7, you can repair damaged files or missing registration information in Internet Explorer 7. To do this, follow these steps:1. Start Internet Explorer 7.
2. On the Tools menu, click Internet Options.
3. On the Advanced tab, click Reset.
4. In the Rest Internet Explorer Settings dialog box, click Reset to confirm.

Reinstall IE if you're using IE6 by installing the ie.inf file

Method 4: Reinstall Internet Explorer 6 by using the Ie.inf file:

If you already have Windows XP Service Pack 2 installed, and you do not want to install Internet Explorer 7, you may be able to resolve problems with Internet Explorer 6 by using the Ie.inf file to reinstall Internet Explorer 6. To do this, follow these steps: 1. Click Start, click Run, type %systemroot%\inf, and then press Enter.
2. Find the Ie.inf file that is located in Windows\Inf folder.
3. Right-click the Ie.inf file, and then click Install.
4. Restart the computer when the file copy process is complete.
