Router / Network settings, throw in Comcast for good measure. - Tilted Forum Project Discussion Community

Chingal0 · 04-30-2004, 11:18 AM

OK! I have searched for and read almost all 3 pages of search results and still have a question. Comcast recently has been doing its crackdown on people using hubs and still getting internet out of both, and thankfully I bought a router. By buying this router, I was under the assumption that I would be safe from said crackdown, and therefore be able to use the internet on all 4 computers on my network. My current configuration is..

Internet to Linksys router. Port 1 and 2 are computers 1 and 2, port 3 goes to a hub which computers 3 and 4 are connected to. As of now, computers 1 and 2 have internet, 3 and 4 do not.

Ok. I read something about DHCP being enabled, I should be fine.. but that got me thinking. With Comcast, they tell you that under TCP/IP and the general tab to obtain IP automatically. I checked my router settings, and in my TCP/IP should I set each computers IP manually instead of letting it pick automatically? Does that make sense? I hope so.

What are the current settings for all of your computers? Are all 4 set to DHCP or are all 4 set to manually assign IP addresses? Is there a mixture?

By "Internet to Linksys Router" do you mean that it's one of those Cable Modem/Router combinations, or is it a router hooked into a cable modem?

Chingal0 · 04-30-2004, 01:09 PM

I am not sure what all of the computer settings are, but I will check it out today.

I have the new GI issue Motorrola modem for internet, that runs to a Linksys router.

Edit: Computers 1 and 2 are both obtain automatically, not sure about 3 and 4, altho I do know that computer 4 is running windows 95 (ya, my parents office computer, they refuse to upgrade to the 21st century) but the windows 95 comp was running perfectly fine for months, until the new Comcast drama.

What is the model number of your linksys router?

Chingal0 · 04-30-2004, 05:05 PM

Model BEFSR41

Ok, if you have the DHCP server in the router enabled then you should be ok. All of the computers should be on "obtain IP automatically", in the TCP/IP settings.

That should fix any problems you have with internet connections.

As far as Comcast is concerned they will only see the Linksys Router, they should not be able to see the rest of your computers.

Unless, of course you turned NAT off in the linksys router (NAT is ON by default in all Linksys routers).

jujueye · 04-30-2004, 05:45 PM

I have a Netgear RP614 router. With the NAT (network address translation) on board, the only thing they see from the outside is the IP which is assigned to my cable modem. On the inside, I have two machines with completely different IPs, assigned by the router. Good to go!

Chingal0 · 04-30-2004, 06:09 PM

Two different yea, but are they static?

Generally yeah, but inside the router network. They are internal addresses, like 192.168.0.1, 192.168.0.2, etc... You cant get to them directly from outside--you have to setup the router to forward certain port requests to certain internal machines.

Chingal0 · 04-30-2004, 06:47 PM

Right, so I will need to do (instert instruction here) to get comps 3 and 4 working? Set their IP's in sequential order as stated above? Or is that even the problem? I have no clue whats going on.

gigawatz · 05-01-2004, 04:22 AM

ok, from what I'm reading, this does not look like a computer configuration issue.

This appears to be a connectivity issue. From your router to your hub, do you have connectivity? Make sure that one end of the wire is crossed either in the cable or on the router or hub. If that cable is not crossed, you will not get connectivity lights on either the router or hub. Check that first.

If you have said lights, then ensure that computers 3 & 4 are configured for DHCP.

JohnnyRoyale · 05-01-2004, 07:16 AM

Here's a question: Is that your linksys, or the Cable companies?

If it's yours, and you can log into it (use one of the computers that has internet access to open a web page to the gateway, which is usually 192.168.1.1) The default login is admin for both user and password.

Once you're in, look at the top of the web page, there will be grey boxes with words in them, which will read setup password, status, DHCP. CLick on the DHCP, and make sure that that's enabled, AND make sure there's enough addresses for the number of computers you're using (I usually setup about 20 addresses minimu.)

Once you're sure that's good, go to the two machines that can't access the internet, and check their IP configuration. Make sure they're setup to get an address automatically (on 95, right click network neighborhood, properties, tcp/ip properties). Once that's setup, you should reboot to let the machine get the IP.

Now, as gigawatz said, there may be a connection issue, Check the hub. Does it have one port on the end that has a button or push-in slot, or it's labeled differently? If so, you need to put the cable that connects the router to the hub in that port, and try pushing the button, and see if you get a link light. then try rebooting the PC's again, once your sure there's a light on that port.

Chingal0 · 05-01-2004, 12:24 PM

My router, I logged in and checked the settings yesterday and they seemed fine. The computers were working fine up until about 4 days ago, and that is where the problem lies. I am not sure what Comcast changed, but I do know that they did change things regarding multiple computers on 1 connection - IP.

As far as having the computers plugged into the uplink etc, I troubleshot that when I set the network up, and everything was running smoothly. I'll double check the connections etc, and make sure nothing has been changed and hopefully I can figure it out.. probably not tho.

crewsor · 05-02-2004, 02:53 PM

I don't think your problem is something Comcast did. They should see only your router. I would suggest resetting your modem, and your router with all your computers shut down, then restart everything. I use comcast and have 4 computers on wireless access and was under the impresssion that they don't care how many computers you have on a home network.
Also have everything set to DHCP so the IP addresses are pulled automattically
