Router problem: 3C510 , Can't access Web. Lan works fine. Wxp pro.

[TomBilliodeaux]

I have a static Ip connection and have shared this DSL connection using Wxp ics and a hub before the router. (3com 510 E-1).

I set up the 3com 510 router using the instucted 3Com IP address and TCP/IP settings for my IP and the DNS addresses.

The LAN between my 2 computers works fine. DirecTVDSL accesses its site ok and the connection is verified showing active at 1.5mb/s.

I cannot access the Web with IE or any other browser.

I shut down all firewalls on Wxp and ZA, and enabled the 3Com options to "allow all" in setup.

What else can I do to access the web?

 

[TomBilliodeaux]

anybody?

If your router works like mine, and i assume that it does, you have to set the router to your ISp's address and each of your connections to the router to automatically obtain an ip address from your router.

Ok too much chitter chat! Here is what I think you have to do. Chuck the router or the HUB - I would chuck the hub. The more things you have in the way the more complex. Take the router's WAN and plug it into the DSL Modem/Cable Modem. Plug into the router on the LAN side and get on the same subnet as the router. Next point your gateway on your computer to the address of the router LAN side. Then set up DNS and you should be ready to go. Let me know if you need any help! Blessings!

p.s. remember a hammer fixes it all ;o)
p.p.s. don't access IE that doesn't tell you much. Ping cnn.com or yahoo.com or whatismyip.com that will tell you if you have interent

 

[BIGMACC]

theXing's dead on!!!

Your router will have a WAN address and a LAN address. Forget the WAN for right now. Hell I can't add anything that thXing hasn't already said!!

Do make sure that you can also ping your router's LAN port. That way you know it is working properly, then, again what theXing said, try pinging outside your router (i.e. yahoo.com, etc.).

I don't understand the need for the hub before the router. Config should be: DSL Modem then router then switch or hub. Is the router a network appliance as well? Is it serving IP addresses to two computers? If so, is it set up properly?

Good luck!

Don't ping www.cnn.com, they drop pings

 

[theXing]

That they do - Thanks for the correction!

 

[TomBilliodeaux]

Thanks guys, but its not working. this is what i have:
DSL ethernet-->3com 510 router : Lan:-->2 nic computers.

Settings: 3com router:
IP 65.186.237.224 this is ip of my ISP provider (STatic connection) Is this the right thing here?
IsP gateway: 65.186.237.225 Provided by my ISP also
Domain: 216.227.94.39
216.227.78.39

on my nic 1: I enter my Ip and sub addresses:
192.168.2.2
255.255.255.0
D.Gateway: 192.168.2.1 (The ip of the 3com 510).
216.227.94.39
216.227.78.39

Could not ping yahoo.com!

I can ping 192.168.2.1.
I can ping 65.168.237.224
I can ping 10.5.1.2 (Directv dsl)
I just cannot get out with IE or MSN browsers.

I have to disconnect and reconnect to get on the net, so hard to try things.

 

[theXing]

Alrighty, let's get down to the nitty gritty!

First can you ping the following whatismyip.com, yahoo.com, and google.com. If you cannot you do not have internet working. The others are all internal so they don't mean much.

So, that takes us down to step two.

Here is how you should set it up:
Computer 1 (Refered to as C1):
192 isn't going to hack it. It is better to use a 10.
So C1 IP: 10.XXX.XXX.2
Subnet Mask 255.255.255.252
Computer 2 (Refered to as C2):
C2 IP: 10.XXX.XXX.3
Subnet Mask 255.255.255.252

Router's internal IP
R: 10.XXX.XXX.1

*** ENSURE ALL XXX are the same respectively ***

Go back and ping between the two computers ensure that A.) you have working network cards B.) you have a working network.
Next ping the gateway. If this works your half way there.

Next set the WAN side of the router to the same IP range as your internal DSL IP address.

So if your internal IP address on the modem is 192.168.1.1 the router should be 192.168.1.2. From here try to ping the addresses above. If your addresses are of the three class types you will have issues.

Here is what it should look like.

C1---C2 (10.XXX.XXX.2, 10.XXX.XXX.3)
|
|
| (10.XXX.XXX.1)
Router
| (192.168.1.2)
|
| (192.168.1.1)
DSL
| (External IP address)
|
|
World

P.S. I don't want to belittle you, but recheck how you wired up your DSL -- > router -- > Computer. Make sure WAN is connected to router and not an actual LAN port. This could cause a world of hurt!

 

[TomBilliodeaux]

The problem is with DNS.
I can ping yahoo, but only by entering the ip address 216.115.109.7 or Pricewatch by entering 204.57.71.5
I can even access Yahoo's site thru IE if i enter the above address , but cannot access anything via a name.

I have manipulated the settings in TP/IP every which way with no results.
My isp's static connection is suppose to be the easy way to configure, but not with this 3com router.

I have set the router settings as my provider gave me:
Even allowed the router to auto DHCP.

my nic has the same static dns address the router has. Without that being the same, ping will not work.

Is the router trash?
It is new, but so what.

 

[theXing]

If you can ping by typing in the IP address then yes it is a DNS issue. What you should do is contact your ISP and ask what DNS servers you should be using. Also if your router has a firewall ensure that you have the DNS port opened. I think it is 53 this is an outgoing port that needs to be opened. Keep in touch.

P.S. A quick search in the internet revealed that your product is out of service so I think you may be better of returning it if it doesn't work. 3Com 510 Router

 

[TomBilliodeaux]

It does indeed have a firewall and I can also bipass it but not sure how yet as it wants an Ip address in the DMZ as it is called.
It has a setting screen to allow certain ports. I just don't know what to specify.
Port IP
83 192.168.2.x the 3com puts the 192.168.2___ with a blank for one to add whatever, 2,3,4.
83 192.168.2.3

something like that?

The odd thing is that my 2 computers can share this connection fine using Wxp's ICS soft and a hub, with the settings my ISP gives me, so I would think those settings should work on the router as well.

 

[TomBilliodeaux]

I Got IT! Or Rather 3Com support got it.
Have to say, it was nice to have support, even for a discontinued hardware item. 3Com is good.

The solution was in the TCP/IP settings:
to allow all NIC's to use "obtain Ip address automatically" in tcp/ip settings, AND to enter 192.168.2.1 (the 3com 510 router's ip address) as the DNS server address. No secondary DNS server address was entered.

So the router assigned IP addresses to the nic's on each computer, but the nic had to point to the router for the DNS server address, which was the Router.

Thanks to Mosel Lumis, 3com tech support.

I'm glad you got it figured out sorry I was unable to respond to your pm in time, its a good product, wait ?til you get the print server running its very cool.

 

[TomBilliodeaux]

Thanks for the interest.
I still have not resolved the problem. After using the 510's IP address for the DNS server address, I could then access web sites, but later realized that I could not access any secure site such as Paypal or any link once logged on to a site. could not login once reaching a site.

When switched back to using Wxp ICS and my hub, I had no problem, so I know the problem was not with browser settings.

3com technical support went thru all the settings and advised me to send it back for return.
They gave me an RMA and it is gone.

I am concerned that the problem was not with the hardware.

Is anyone using a 3Com 510-E1 with Wxp successfully?
Also, I bought this router for the printer server. Will an inkjet work such as a cannon? I read somewhere that it does not work bidirectional. Don't know it that applies to a standard inkjet or not.

Hope this helps

I use hp deskjet 660c



How do I set up the Print Server for a Windows Host based printer?

Print Server may not work with certain printers

Printers that are Windows host based, including printers from Canon, HP, and Lexmark, require bi-directional control over a parallel port. They will probably not function correctly with the 3Com Home Ethernet Gateway print server.

A printer that is host based relies on the host computer's processor to generate printable pages. Most host based printers on the market today use the GDI interface built into Windows.

To determine if a printer is host based, check the specifications to see if it supports DOS applications without Windows running. If it does not, then the printer is a host-based device.

Additionally, printers that use a USB or serial port will not work with the 3C510 print server, as it is parallel port based.

In these cases, you will need to use one of your PCs to share the printer with other PCs on the network. For details on how to share a printer using MS Windows, see Windows help on "enabling file and printer sharing" and "sharing a printer" on your computer.
