Cannot Ping Router Sometimes (wierd)

This is a tough one. I think I've tried just about everything. I've even had a Microsoft Certified friend of mine come look at the issue. Although he's not a network guy and recently graduated he still couldn't figure it out. So a BIG KUDOS to those who can. Here's the deal:
I have two computers networked sharing a DSL connection. I am using a router to network them. The router is a Airlink 4 port 10/100 router. One of the computers is a Windows 98SE equipped PC and is located downstairs in my house. The other is a Windows XP PC located upstairs. The windows 98 Machine works fine, will surf the net, can ping the router, can get into router configuration, etc. However, the Windows XP machine cannot surf or even get into router setup. When I ping the router from the XP machine the XP machine will return anywhere from 1 to 3 of the pings successfully. But, never all 4 pings to the router are sucessful. The things I have done are:
-Ping the NIC card on the XP machine (came back fine)
-Put the XP machine downstairs and hooked it to the router. No go, XP machine still could not surf
-Hooked up the XP machine DIRECTLY to the DSL modem,not using the router at all. surfed like a charm, no problems at all.
-Tried changing the ports on the router for the XP machine, still no go. However, the Win98 Machine will work on any port.
-Tried the Windows 98 Machine upstairs, ran just fine through the router.
-Tried disconnecting the Windows 98 Machine and Just had the XP machine hooked to the router, still no go.
-The XP machine (when hooked to the router) can release the IP but cannot renew it. When it goes to renew the IP there is a very long pause then it returns with "unable to contact DHCP server" or something like that.
-Uninstalled the NIC then reinstalled.


There are some setups on the router I did not complete. The reason for this is because it said I should get these numbers from my DSL provider. I called Verizon and they were unable to help/didn't know what I was talking about. The numbers were DNS address, IP address, and Gateway. I tried using the computers IP for the iP address and used the router as the gateway but then the windows 98 machine wouldn't work at all and there was no change in the windows XP machines ability to connect. Here is the info on my connection:

Coppell, Texas Verizon DSL
Always connected
IP: 4.63.71.239

I don't normally give out my IP, but hey if anyone wants to hack into my computer and fix it feel free :) hehe.

can you not set your router to use DHCP to get the IP, subnet mask, and gateway from your ISP? that's how mine is setup, and then I have an internal IP range (172.16.10.x) that my router hands out to my PCs that are connected to it. btw, if you got it, I'm the one who sent you a popup :-)

Hey Jonathan,

Thanks for the reply, but no, it doesn't appear that I can just set it up to obtain that info automatically. Although, It does say this at the bottom of the setup screen "The Broadband Router is a device ideal for home networking and small business users. Most users will be able to use the Broadband Router's default settings. If you have different settings, the Quick Setup will lead you step by step to configure the Broadband Router. Its easy setup will allow you to enjoy risk-free Internet access within minutes." Also, I didn't get your pop up message :( sorry, but keep the answers flowing. I have added another 200 points, for a total of 325 points to the person who can answer this.

P.S.- Also I didn't mention before that there are no firewalls enabled on the Windows XP computer, thought someone might say that was the problem, but the XP firewall and Norton have both been removed/deactivated. I will say that I am by no means a network guy (actually I am not even in the IT field) so any suggestions no matter how miniscule are worth a try to me. I could have easily over looked something.

Casey,

That was going to be my next question about the built-in firewall on XP. Airlink huh? Can you give me the model number/name? is there a website for them? I tried a couple of sites I found on the web and they came up empty. If I can see some specs, I might could help you. how old is this router?

Also, can you go to start run, type CMD then hit return, and then type 'ipconfig /all' and post the output?

As you can tell I can't get the upstairs pc to renew its ip right now. Sometimes I'll go up there and check the IP and it will be correctly set at 192.168.1.3 but it still won't ping. After I released the IP earlier this afternoon I couldn't get it to renew (figures). Whats wierd is even through all of this, Windows XP still says that the connection is "ENABLED" and if I unplug a cable the computer makes the "ba da du" sound and says "network cable unplugged"....ugh...

Thanks for the Help Jonathan, keep it coming and lets figure this thing out!!

First things first, although that is a site that sells the router, that is not the site for the router manufacturer. Here is the correct site for support: http://www.airlinkplus.com/faq.htm Its actually the faq page, but that is where you should go for tech support, firmware upgrades, etc.

Now, the IP address that your XP box is getting is called an APIPA Address (Automatic Private IP Addressing is what APIPA stands for) That means that it is not connected to a DHCP device or one of the devices is not configured quite right, OR there is a problem with the network cable. It looks like the Win98 box is getting its IP Address correctly.

Another Question: is the XP box XP Pro or XP Home?

Try this. Take the XP box back downstairs and hook it up directly to the DSL Modem, bypassing the Airlink for now. Do an Ipconfig/all and post that. If you can't surf, reboot both devices then try again.

Next, hook up the Win98 box and do the same thing.

If you can surf using the DSL modem, and get an IP address just fine, then that makes me wonder. That says that DHCP is working fine on the XP box.

Next, hook the router back up to the DSL modem...you may need to reboot the modem for this to work... and hook up the win98 box. Can you surf? If so, unplug the cable from the win98 box and plug it into the XP box. Reboot the router and or XP box if necessary after you hook them up. What are your results?

By the way, your router should most likely be setup as Dial-Up xDSL(PPPoE), and that is the same as DHCP. This is one of the first options in the quicksetup of the router. If they only gave you a password and service name, then that is what you have to choose. If they gave you a Fixed (static) IP address, then they should be able to provide you the DNS, gateway, and subnet mask. If they can't give you DNS server settings, chances are that you will need to choose PPPoE so that your router will get those settings automatically, via DHCP from verizon's network.

is your modem a Westell or a Fujitsu?

Jonathan

Commented:
Could be a duplex setting problem on the XP machine's network card. It should be set to Auto or similar. Try 10MBit Half Duplex.

Ok, Here's the other Goodies:

With the XP machine hooked Directly to the modem there are NO issues. It will surf and connect fine.
With the XP machine connected to the router WITHOUT the windows 98 Machine Connected there is still no go. With the Windows 98 Machine upstairs using all the same connections as the XP machine there are no issues. The Win 98 Machine can surf and do the web fine from upstairs.
The NICs duplex is set to Auto.
The Modem is a Fujitsu
The XP box will not surf from the cable that the Win 98 box was using to surf from (get the 98 system working then unplug the cable and plug it into the WinXP machine).
The XP computer uses XP Home

Sorry about the website jonathan, that was the first one that came up when I surfed for info on the router. Later on I found the company's website. I guess that the router is too new to have firmware updates because there are none avail. on the company's website.

Keep the ideas comin.

Here is what it said when I set up the router as PPOE. Also, I couldn't surf or connect to the net. I am sure I have a static IP but verizon doesn't list any info about it on the website nor do they even know what I'm talking about when I call them :( ugh!!

hmmmmmmmmmmmm

ok, hook the XP box directly to the DSL modem once you have verified that you can surf, do an 'ipconfig /all'

also do a 'route print'

post both and I'll mull it over.

This has GOT to be something simple... I'm almost to the point of buying the stupid router just to see if I can duplicate the problem. When it asked for a MAC address, did you choose to let it Clone the manager's MAC Address?

Also, are you absolutely positively certain that you have enabled DHCP with a pool starting at 192.168.1.2 and ending at at least 192.168.1.4 (or higher)?

XP Home?? Hmmm all of my systems are XP Pro, which is a little bit different if I recall. I'll have to dig to see if I have a copy of XP Home to play with.

 Sorry, I didn't know what you meant by 'print route' so I used Tracert and posted the results. All of these are from the upstairs computer, just taking the cable that was plugged into the router and plugging it into the DSL modem and unplugging the router from the DSL modem. Instantly I am connected to the web.

Also,

I spoke to verizon and they said I do not have a static IP. Maybe I am setting this thing up wrong totally. Although I have never used PPoe Before (always TCP/IP)

The options for set up include
. WAN Type
Specify the WAN connection type required by your Internet Service Provider. Specify a Cable modem, Fixed-IP xDSL, or PPPoE xDSL.

   Dynamic IP (Cable modem)
A Cable modem requires minimal configuration. When you have set up an account with your Cable provider, the Cable modem will automatically configure itself, so you probably do not need to enter anything more. However, if there is a Domain Name System (DNS) server that you would rather use, you need to specify the IP address.

   Static IP (Fixed-IP xDSL)
Some xDSL Internet Service Providers may assign a fixed IP address for your Broadband Router. If you have been provided with this information, choose this option and enter the assigned IP address, subnet mask, gateway IP and DNS IP addresses for your Broadband Router.

   PPPoE (Dial-Up xDSL)
If you connect to the Internet using an xDSL Modem and your ISP has provided you with a password, and Service Name, then your ISP uses PPPoE. You must choose this option and enter the required information.

   PPTP
If your ISP provided you the PPTP Account, PPTP Password, Host Name, Service IP Address, IP Address, Subnet Mask and the Connection ID, then your ISP uses PPTP. You have to choose this option and enter the required information.

Regardless, I think you might be better off at this point to default the router to factory settings and start over, use the quick start guide and this time choose PPPoE, which stands for Point to Point Protocol Over Ethernet.

Lets see where you are after that.

A Domain Name system (DNS) server is like an index of IP addresses and Web addresses. If you type a Web address into you browser, such as www.yahoo.com, a DNS server will find that name in its index and find the matching IP address : 61.218.71.81.
Most ISPs provide a DNS server for speed and convenience. Since your Service Provider many connect to the Internet with dynamic IP settings, it is likely that the DNS server IP addresses are also provided dynamically. However, if there is a DNS server that you would rather use, you need to specify the IP address below.

At the bottom there is a button that says "CONNECT" and a button that says "DISCONNECT" If I hit either nothing happens. Also when I do this, the one computer that was able to connect to the net stops being able to connect...man this Sucks. I'm about to beat the router into a million pieces.

At the bottom there is a button that says "CONNECT" and a button that says "DISCONNECT" If I hit either nothing happens. Also when I do this, the one computer that was able to connect to the net stops being able to connect...man this Sucks. I'm about to beat the router into a million pieces.

No objections here. I feel bad that I never responded to Casey's last post. I guess I must've gotten tied up in a project and it slipped my mind.

Casey, if you're still there, did you ever find the answer?

Problem solved after total format and reinstall of XP. Gave points to Jonathan for his relentless help. The harddrive on XP machine is going bad and has actually began the SAME problem earlier this week (After a year of perfect operation!). I should recieve my new Western Digital Raptor SATA drive today and will be putting in a new drive.
