I have an ethernet internet connection. I have a laptop and desktop that connects to the modem/router. The modem/router is capable of handling 4 wired connections. When, I have the internet on the laptop and then try to connect desktop to internet, the desk top cannot identify the network and I have to reset modem for it to be reconfigured. If I have one connected to internet (laptop or desktop)and try to connect the other, the second computer can't be configured and I'm told to reset modem/router(or adapter)?

How do I get them to work at the same time?

I have windows 7 on both computers. I also have Time Warner cable for internet service provider.

Hi reaching
May we know the make and model of your modem/router?
 
To reset your modem (if not self powered ie power adapter is external),
Power on adapter and switch on the device.
Find a small (1mm)  pit on the modem/router (usually located at rear or bottom of device, press the button inside it and hold pressing for about 10 seconds or the LED lights on device blinks all atonce. Use a ballpoint pen or something to press.
Are you able to login to settings page of router/modem?

which ever PC they used to setup the modem/router, plug it in all by itself. Surf into the software and look for something called Clone MAC address. Should have a button or something you click. Click it. The unplug the modem/router and plug it back in...do not reset it. See if that solves the issue.

 

Just FYI, if in the future you have to reset it, surf in with that same PC and do all that again.

If what CaveDweller2 mentioned is true in your case, you will need to buy a new router and clone your PC's (which can successfully connect to internet) MAC to it and then connect it between your pc and modem.

 

@ CaveDweller2 : Seems we are meeting over topics again. No offence over it, please :)

Okay, I did run the toolkit and will paste below.

 

@cavedweller2-  I don't know what "surf into the software" means.  I tried to look in the start menu and saw nothing like you described.

 

I have a Technicolor modem/router from Time warner cable.  I do not have wifi so the router portion is disabled.  I do not have access to the router.

 

I have been powering it off.  I have not reset it yet(I found the little reset button).  I only have phone and internet services through the device.

 

Here is the log:

Hi,

From the log its clear that your modem doesn't create a local network. So that may be causing failure to access internet from multiple devices .

You'll have to either add a seperate router/switch or use one machine at a time.

 

To access modem/router settings, please see the documentation of device or specify model to us. I found multiple IPs for the access on google, but unsure which works for you.

If you've tried previously to access the device settings but got denied (not failed), you must enter default username/password or the one configured. Else reset modem/router.

The router information is on the device, however when I type in 192.168....(as listed on device), it does not take me to the router sign in page. It takes me to google matches. I am not shown the page to type in username and password.

Could it be an internet service provider block?

Initially, one the computers would say "can't find valid ip (or something like that) and would offer me the choice of allowing windows to configure an ip for me. It stopped doing that and tells me to reset. Or sometimes it would say can't find valid ip configuration but no longer offers to give me one.

What does surf software mean?

If I reset modem, would it mess with my phone service?

I have my windows networks set to public. Would this affect whether the local router builds a network.

This might be a case where you need to call your isp. It sounds like your modem/router got bridged, which just means it is just a modem. But I'm not 100% sure about that, what I do know is something isn't working correctly.

 

If you'd rather not I understand but I need you to understand in the end you might have to call them anyway.

 

you mentioned a 192.168 address, is it 192.168.100.1 ? I'd try doing an actual reset on the router as Nikhil_CV has suggested. Shut your PC down. Take a pen or straightened paper clip, press and hold the reset button for a count of 10. Normally it is near the power plug on the device and it's labeled but I have seen them all over. It's normally inside a little hole, hence the pen /paperclip. Once all the lights go back to normal, power on your PC.

 

click the Windows button and type CMD and hit Enter. A black box should pop up. type ipconfig and hit Enter. Do you still see the 74 address or a 192 address for your IPv4?

 

If you see the 74, call your ISP. If you see the 192 and can surf come back and let us know. Well either way come back and let us know lol.

Okay, I was scared but I reset the modern/router.
The ip address still begins with a 7...the exact same number.

Cavedweller, I do remember talking to the service provider when we first got the internet-tech support. Router was not bridged and he said it should be and bridged it. So, I guess that's the problem.

I'll call them and report back.

By the way, both laptop and desktop have ip numbers that don't change and begin with 7...

Make sure they aren't going to make you pay more a month for it to be unbridged. Because it would be cheaper to order a $20 - $30 router from Amazon.

 

Small and simple networking lesson. What routers do is separate but connect 2 different networks. In the past few years ISPs have moved away from just providing modems to providing modem/router combos. So the way to look at it is the wire comes from your wall to the device they supplied, in your case that carries the 74 network. Inside that box is software that puts a wall up, on the other side should be the 192 network. What that wall does is no matter how many things are on the 192 side as far as the 74 side there is 1 on the other side. And the software keeps track of all the traffic. What they did was tear down that wall so now all you have is the 74 network, which will only let 1 device connect at a time.

Thank you for the explanation, Cavedweller2.
Now, I have a very important question; I hope I can explain it properly.

I have an ethernet connection. I want to keep my connection wired. I DO NOT WANT WIFI enabled. So, if I get my own router, is it possible to set it up so that all computers can use my connection to the internet without enabling wifi? If so, how?

I hope that makes sense.

Yes you can not have wireless. And the specific steps would depend on the router but basically somewhere in the settings there is a Disable button or drop down in the wireless settings. You could look for a router that doesn't do wireless, I think they still make those for home use lol.

I would suggest you check the cabling.  The line from outside should go into the wan port of the router.  If cabled to a lan port you will get the ip address you are getting which is the one that should be on the wan port of the router.  This would also explain why you only can get on pc on at a time and why you can't access via a 192x ip address.
