Can't connect to internet with Windows 7

You need to reset your Internet settings. I created a batch file turned into an executable that will do just that. It initiates over 10 commands to help reset the network. Right click the Nuke TCP Reset and run as Admin. Once completed you computer will auto restart in 15 seconds.

You anti-virus software may flag the file as malware. Rest assured it is not. I made it myself which is just a batch file. I think the reason as to why some anti-virus software flags it is due to being compressed with the 7Z compression and for some reason some anti-virus software doesn't like 7Z. It's just a false positive. If you don't want to run this then I can tell you what commands to run yourself manually, but it's over ten of them. What this does is fire them all off at once in 5 second intervals. So it's all automatic.

Once your TCP/IP stack has been reset you should be able to simply plug in the Ethernet cable from the modem into your computer and away you go. No password or any of that. The password crap is a remnant of some other configuration you had going there. This will hopefully reset all that back to what it was.

Yes, you should get a router as that modem is just that - a modem. So there's no SPI (Stateful Packet Inspection) and NAT to afford you some basic networking security. Using just the modem now, every time you switch computers you may need to reset the modem as it will pick up different MAC addresses from each computer and change your IP address as well.

Some modems are a modem/router combo, but yours is not.

Here are some of the commands it fires off. For some reason my .EXE nuke does more than what I have published at Github. GitHub - 737simpilot/tcp-ip-reset: Resetting Winsock in Windows 7 (Click Source).

You should see the Ethernet adapter in the Device Manager. I have an Nvidia nForce 10/10/100 Mbps Ethernet
In the Control Panel if you go to Network and Sharing Center select Change adapter settings
You will see the Ethernet adapter there
You can show its properties and status
You will see the Ethernet adapter specification in the user manual.

Also, in the user manual you see that the Ethernet port is called LAN (RJ-45).

Lastly you will see the Ethernet port on the back of the computer. Here a yellow Cat 5e Ethernet cable is plugged into it.

MisterEd,

Cool diagrams. I am at the library now since that is the only place I can currently access this site, lol. But I will def check my control panel for the 'change adapter settings' icon when I get back home. I do not think it is there on my version.

I did see some mention of tcp/ip 4 and tcp/ip 6 and they were both checked off already so I left them alone. It offered me the option to 'install' them, but since already checked off, left well enuf alone.

I do have something mentioned under network adapters, but it does not have the word 'ethernet' in it. Can't remember what it said.
I was poking around for hours before I saw the 'show hidden items' option somewhere, and clicked on it, and the network adapters tag showed itself ! Arggghh!! Why did they hide it ? Because it wasn't working properly ?

F22 Simpilot,

Thanks. I am afraid of doing all that, at this time. Maybe later, lol.

About the MAC address : I had a MAC address on the modem itself, which is what I read off to the cable company as we were getting a connection to work. I didn't think the computers had MAC addresses.

It is my understanding that the cable co only is interested in the MAC address of my modem, not ip address or mac address on the computers. No ? They said it was just the modem MAC they wanted. I told them it worked in one old computer and not the newer one, and were fine with that, no mention of my having to call them back to reset anything, to use another computer.

This website is combining my posts for some reason, guys. Sorry about that.

OK, more data. My control panel settings are different. I don't have any 'change adapter settings' tab. I do have a 'wan miniport (PPPOE)' entry in the list under 'network adapters', and I get a popup screen saying 'connecting to broadband with wan miniport PPPOE' but it never connects. Still haven't found the word 'ethernet' anywhere on the newer pc.
Thinking I might fix things by downloading and installing drivers for the network adapter, since troubleshooting says I need them. Where is a good place to download drivers? Thanks.

That PPPOE entry, right click and delete it. After that you may need to reboot the computer.

That's a bold move.

Can I re enter the PPPOE entry later on if I want to? What about uninstalling stuff? Can it later be reinstalled just by clicking 'install'?

I am hesitant to delete or uninstall drivers, adapters, connections, etc without a plan to restore them.

Is the goal of deleting the pppoe entry to get windows to reacquire it (in a better form) on reboot ?

Should I try downloading drivers for my network adapter? Windows says I need to. I would have to get them from a third party website. Google searching says all those sites give you bloatware and viruses along with the drivers.

I think I used CNET to download some dial up modem drivers a few years ago. They would not install properly even though I followed the directions.

Any safe websites to get drivers?

The issue is that you more than likely added a PPPOE connection which is a DSL connection and now Windows is trying to make a DSL connection instead of using your broadband connection. So deleting that connection should go back to what it was before and connect straight away to your modem.

Yes, the PPPOE connection can be created again within the options in Windows networking.

What is the make and model of your computer? You want to get your drivers for your computer or motherboard from the manufacture's website and not some site like CNET or whatever. Those can be laced with Adware or whatever...

No make an model. It's a build. I bought it from a gamer 10 years ago. The network adapter it is using is ISATAP, which is supposedly a problem. ISATAP does something with 32 bit machines to increase speed or something. It can be 'disabled', which supposedly could fix things.

The windows 7 troubleshooter tells me I don't have properly installed drivers for the 'network adapter' . I am assuming that the ISATAP, which is the first entry under 'network adapters', is what they are referring to.


It's tempting to remove the PPPOE connection, and see what happens on reboot.

Are you using the built-in network card on the motherboard or a dedicated network card? If dedicated, what is its make and model?

What is the make and model of the motherboard? You can run something like CPUz and it'll tell you under the Mainboard tab. CPU-Z | Softwares | CPUID

Don't know. I am plugging the ethernet into the receptacle for it, which looks like it is the motherboard.

Someone suggested removing the dialup modem card, to see if the bootup would look for something else. Might work.

But I have a modem card in my other pc too, the pc which does connect to the net, and i didn't need to remove it there.

Hi

if the Wifi card is NOT showing under device drivers, please check your Bios settings if its(Wifi)is dissabled it will NOT show under device drivers

No wifi involved.

Thanks, everyone for your help. I have learned a lot about Windows 7 and Windows in general from this discussion, as a user.

I think I have solved the problem ! I looked back at my notes and saw that I had been looking at the bios years ago, so I looked in bios and saw lots of interesting stuff, one of which was that the 'onboard LAN' was disabled. I don't remember doing that, but maybe the previous owner, a gamer, did it.

Anyway, I enabled the onboard LAN, and rebooted, and I got online ! I poked around and right clicked on the connection, and the troubleshooter asked me something, and clicked yes, and it then said it was 'making some changes' but didn't say what they were.

At first the download speed was awful, as in 1.0 Mbps. That was with an unknown version of Firefox that I was using. I then installed what is supposed to be Firefox 115, and my download speed is now 7.9 Mbps. Supposed to be max of 100 Mbps, but at least I can navigate the websites in a fairly quick manner.

Thanks again to all.
