Windows 7: Unidentified network problem again

Unidentified network problem again

Hello,

Thanks for all your work on this problem, glad to know I'm not alone. I have tried many of the solutions I found and come up with nothing.

I have a brand new Acer Aspire AS5742 running windows 7 64-bit home premium.

I am trying to connect to the internet in the simplest way I know how - ethernet cable directly into the cable box modem from the wall, no router.

When I plug in the cable it comes up with the unidentified network, no internet access message.

I have tried this fix: Windows 7 Unidentified Network, Limited Access, No Internet Connection Problem Resolved

to no avail (because the ipconfg is not showing a default gateway at all, i just put in 192.168.1.1)

I have also tried the "put 12 random alpha numeric characters in the network address" fix

I have disabled and uninstalled bonjour

I have tried an ipconfig /release /renew

I tried copying the ip address and other configurations from this, working, computer and putting them into the laptop, no luck.

I have a desktop that I am working on now, if I take the cable that is connecting the desktop and put it into the laptop instead, it does not work, so it's not the cable or the modem.

I have been online with a public wifi connection at the library, so the computer seems to work fine in some settings.

I've attached the ipconfig /all

Thank you in advance for the help. Let me know what other information I can give you.

here is the ipconfig /all

From your ipconfig I don't see anything coming from the modem at all, only the default windows ip which shows up when there is no connection.

The link you showed only works when there is a default IP of 0.0.0.0 which is different than the problem you seem to be having, in fact I was most likely the one who posted the link for that.

I'd say that either your Broadcom eithernet adpator doesn't have the correct driver or there is something blocking the wired connection like your A/V software or a third party firewall. You sometimes need to uninstall your A/V as often times disabling won't work. Either that or look around for a better driver for your broadcom adaptor and make sure it's installed correctly.

no luck

I updated the driver to the latest and uninstalled my anti-virus software. I was running avast. Still getting a 169.x ip

Sounds like you did try putting in a static IP address, right? If so, it should look something like this:

only your would be 192.168.1.x

still nothing

Yeah, I tried taking the settings from my working connection, ip, subnet mask, gateway, dns servers andthe connection-specific DNS suffix. still no luck.

I am plugging directly into the modem, and even if I try a a 192.168.1.x it still does not work.

Fixed!

I actually seem to have fixed the problem using a fix I found on another thread on this forum. I simply disconnected the coax cable from the modem, and plugged in my laptop as usual. The modem assigned my computer a valid 192.x.x.x ip, and when I reconnected the coax everything was working fine.

Thanks for all your help.

So a modem restart, reboot or reconnection was required, usually that would be the first thing to try.

You kinda messed up when assuming this> I have a desktop that I am working on now, if I take the cable that is connecting the desktop and put it into the laptop instead, it does not work, so it's not the cable or the modem.

Assumptions like this don't really hold water, this is one of the many reasons I tell people to get a router as modems don't do DHCP worth a damn.

Glad you have it working ben.

So I dont assume anything either... are we talking about the Ethernet Cord hard lining into the modem? instead of a router?

I to am having this exact problem... I too have tried the above steps that have failed. But, I have reset, reboot, and reconnected my modem to my computer. I also have the IP addy of above (has preferred next to it)

Not trying to thread jack.. just curious..

TIA,

That 169 IP is just what windows uses when there isn't a functional IP assigned, it's a default no value IP.

Yes you need to unscrew the cable going into the modem then power down the modem and wait a minute, power it up and put the cable wire back in the modem then plug the machines eithernet cable into it. This will make the modem assign a new IP for the machine being plugged in.

Only one machine at a time with a modem, you can't just go from one machine to the other and expect it to work. If you have more than one machine you could set up ICS "internet connection sharing" but there are a few drawbacks to ICS, ideally you need a router.

I just assumed that the Op already went through the modems set up procedure for the second machine so my fault for not covering the basics first.
