no internet connection after fresh install of windows 7

I've seen many messages about this but no solution seems to work.

i just did a fresh install of windows 7, but can't get on the internet.

my device manager says i am missing:

base system device (PCI bus 13, device 0, function 1)
network controller (PCI Bus 3, device 0, function 0)
unknown device (on Microsoft ACPI-Compliant Embedded Controller)

i have another computer to download drivers from, whig i have been doing, but to no avail. Anybody know where i can download these devices?

the computer that can't get connected to my router is:

lenovo t410
windows 7 home premium
intel core i5

  1. Well, usually the most important driver is the network controller one, and once install, you will be able to access the internet and get the rest.
    Do you have a NIC card, or just the integrated network port?
    If it`s the integrated one, what is your motherboard name, and what version of Win7 are you running (64vs32)?
  2. hey there, thanks for the quick reply.

    the only one i know how to answer is that i am running win 7 64...sorry, any way to find out?
  3. These normally come with your motherboard disk, you should be able to find some on your motherboards support section/website. If you go into properties on the device manager and find the numbers under the details tab, you can drop down and receive information about what your missing in the form of: PCI\VEN_14E4&DEV_1681&SUBSYS_026E1028&REV_10

    you can then search for this or break it down into segments and search on-line.

    What Mobo do you have and make sure the BIOS is up to date. Also sounds small but a restart is normally required for things to take effect.

    RUN CPU-Z to find out what mobo you have

    Let me know how you get along

  4. hey, sorry, i'm not smart enough to understand these instructions:

    i tried to run cpu-z, but nothing came up

    i also clicked on properties for my network controller in the device manager. clicking on the details tab doesn't give me any numbers...am i doing something wrong?

    i just downloaded prowinx64 from the intel download center, to see if that would provide me with the driver from the network controller. installing it now...
  5. You can also try some of these advices: http://www.computerhope.com/issues/ch000504.htm
  6. well, running prowinx64 seems to have gotten me a little closer. my computer was able to identify my router! but it is not able to connect. trouble shooting right now, reseting the network adapter, etc. restarting the computer. nothing seems to be working, but i'll keep trying different solutions, and will write back if the problem is resolved or not...basically, after i type in my password, it quickly relies that i can't connect to my router.
  7. Well, check in Device Manager that status of your network controller.
    If you see any exclamation mark next to it, most likely the driver is not installed, and you`ll not be able to connect.

    If there is no special mark next to it, it should be fine from a driver POV, and it`s only a configuration issue.
  8. the network controller seems to be working, as there's no more exclamation mark next to it. So I guess its a configuration problem? Any possible help on how to configure it properly? i've tried all the amateur solutions (turning it off, rebooting computer) nothing works.

    one thing that is weird is that many connections show up as available, but none are marked as needing a password. when i click on my router, it does ask for the network security key, but after i type it in it says that windows was unable to connect to my router...
  9. Are you trying to connect over Wi-Fi?
    If yes, do you have a cable that will allow you to connect directly to it?

    If you manage this, or have a different PC connected to the Router, go in the router`s config page, and change the password.
    Afterwards, try connecting again.

    FYI - the address for the router is usually 192.168.1.1 for their internal IP address. D-Link and Netgear routers typically use 192.168.0.1. Some US Robotics routers use 192.168.123.254, and some Belkin and SMC routers use 192.168.2.1.
    You just type this into a browser, and you`ll get to a login page. Usually both ID and pass are "Admin".

    Try this and get back to us.
  10. before i try to configure the router, here some more info:

    when i right click the internet icon in the system tray, and click on “open network and sharing center”, it opens a window, with the words “view your basic network information and set up connections” on the top.

    visually, there are three sections mapped out: “this computer” on the left, unidentified network (park bench) in the middle, and “Internet” with a black and white (unhighlighted) globe icon on the right. Between "this computer" and "unidentified network" is a yellow sign and exclamation point, and between "unidentified network” and “internet" is an x.

    below that it said, “local Area Connection” doesn’t have a valid IP configuration.

    After a minute or two, it changed. The yellow sign between “this computer” and “unidentified network” went away, but the x between “unidentified network” remained. however, now the internet icon in the system try has a yellow sign with an exclamation point over it. It then remained that way...

    Should i try to fix the router, or is there something i still need to fix on the computer itself?

    thanks!!!!!
  11. Any idea if you have a static or dynamic IP?
    If it`s dynamic, you should check your IS settings are set to automatic:
    http://emedia.leeward.hawaii.edu/itg/wireless-win7-dhcp-config
  12. just checked it and followed directions on the link. unfortunately, IS setting are already set to automatic.

    not sure what to do next...
  13. In this case connect via ethernet cable to the router, and play with the password and other settings.
  14. unfortunately, i can't get on line with my ethernet cable either. after troubleshooting, Windows Network Diagnostics said the problem is:

    'Local Area Connection' doesn't have a valid IP configuration
  15. Ok, in this case, do you have any other PC connected to the same router?
    If yes, check the network configuration on the PC, and try to replicate it on this one.
  16. oh, that's brilliant...

    but just a couple questions:

    1) how do i check for network configurations on my PC?
    2) the other computer is a macbook pro.I'm assuming I look on network, where my wifi address, IPv4 address, subnet mask, router, and MAC address are listed.
  17. Well, I`m not sure how the network configuration looks like on a MAC, but check if the settings are set to automatic, or if there are any specific IP and DNS configurations.
  18. I don't know where to look on my PC, though...
  19. For a PC: Press the windows key on your keyboard, type 'cmd' press enter. Command window will open. type 'ipconfig' press enter
    or go into your network and sharing centre and adapter settings properties

    For Mac: You already know how to do that as written above, or you can go Launchpad, then terminal then enter 'ifconfig -a'

    Fire
  20. thanks for the tips

    but i inputed the IP and DNS configurations form my mac onto my PC. didn't do anything.

    my router still shows up, but when i try to connect, it says "windows was unable to connect to ____ (my router's name)." Didn't even ask for my password.

    sorry to drag this on...but bloody hell nothing seems to work!
  21. Ok, in this case, turn off your router for about 30 seconds - 1 minute.
    Connect again to the router, also to the address for the router settings.

    Still not connected - reset the router to default settings. There should be a small reset button on the back of your router. Still doesn`t work - unplug the power to the router for a minute, and plug it back in.

    Still nothing - give us all the information that you get when you run "ipconfig /all" in CMD window.
    Also try to give us screen shots of the router settings, if you manage to access it.

    Try this, and get back to us.
  22. ok i will - 2 questions first though:

    1) should i take this computer to a cafe or another wifi place, to see if m computer can connect to the internet at all?

    2) in case i need to, how do i get to my router settings? i don't think i can do it from my PC, but can do it from my mac.
  23. If you can test in a different network (WiFi) it would be great, because then you can find out if the problem is from your PC, or the router.
    For the router config, use what I have you earlier:
    "Are you trying to connect over Wi-Fi?
    If yes, do you have a cable that will allow you to connect directly to it?

    If you manage this, or have a different PC connected to the Router, go in the router`s config page, and change the password.
    Afterwards, try connecting again.

    FYI - the address for the router is usually 192.168.1.1 for their internal IP address. D-Link and Netgear routers typically use 192.168.0.1. Some US Robotics routers use 192.168.123.254, and some Belkin and SMC routers use 192.168.2.1.

  24. thanks for all your help:

    1) tested computer on another wifi - did not work
    2) went on router admin page. (192.168.0.1). "admin" did not work for log in and password. It might be because I live in China...?
    3) here is the screenshot when i go on my PC, and in command line type "ipconfig"

    ipconfig screenshot.PNG

    ok, don't think that worked...don't know how to add screen shot into this response bx.

    basically, for all 4 areas (wireless pan adapter, ethernet adapter, and the 2 tunnel adapters), it says media disconnected, and there is nothing after "connection specific DNS suffix"...

    Sorry, hope that helps?
  25. Upload the picture here and give us the link: http://imgur.com/

    Try to contact your internet provider and ask for assistance if possible.
    Is the WiFi router purchased by you, or provided by the before-mentioned internet provider?
  26. here's the link to the ip config. screenshot.

    I purchased the router. I'm in China, and i sometime have trouble communicating with my internet provider, i'm not sure they can help...

    thanks a bunch
  27. tried to release and renew, but got an error message . here's the screenshot:

  28. Go into Control Panel\All Control Panel Items\Network and Sharing Center, click on Change adapter settings, and give me a screen shot of what you have there.
  29. Best answer
    Connect the PC to the router via Cable, and Right Click -> Disable the WiFi network connection.
    Give me a SS of that.

    Also, Give me a SS of the Device Manager, with the Network Devices expanded.

    If you can talk via Skype or Team Speak, hit me with a private message, as this is going too slow.
  30. apologies for the slowness, i can chat on Skype but i live in china and the time difference doesn't help. It's late here, i just woke up for a second and saw your message. will go back to bed soon. if this problem persists, i will send a PM tomorrow evening, my time.

    in the meantime, here are two screen shots.

    1) SS PC to the router, via cable. I only connected the PC to the router, but the router is not connected to the wall...i'm assuming you might have wanted the router connected to the wall for this, but i don't have an extra cable to do that. in any case, here is an image of just the PC to router, with the wireless network disabled.

    2) SS of device manager,

    thanks for your patience
  31. Ok, try to get another network cable, because you need the router connected to the socket, and the PC to the router.
    Check your Router box if you don`t have an extra cable. If not, try to get one from a friend or buy a short one, as it should be very cheap.
  32. will do this tomorrow...thanks!
  33. here are the two screenshots:

    1) http://imgur.com/Iim6Y58
    2) http://imgur.com/eZJuTvx
  34. Did you manage to connect to the internet?
    If not, did you atleast manage to connect to your router page for settings?

    Also, what is the name and model of your router?
  35. yes! managed to get on the internet using the cable.

    my router is Dlink Dir-615

    went on router page, but admin / admin does not work for username / password.
  36. Use Admin for Username, and leave blank field for pass.
    Here`s more info: http://pcsupport.about.com/od/d-link-default-passwords/a/dir-615-default-password.htm

    I`m grad internet works on cable :D
    Now it should be easy to make it work with wireless also.
  37. thanks a ton! if i have trouble with connecting my PC to the router, i will write back.

    thanks again!
  38. Sorry to bother you again -

    but I still can't get the wireless router to work.

    I changed the password, and reset the router. I re-enabled the wireless network connection, but my computer can't connect.

    any suggestions?
  39. do you receive any error message?
  40. sorry for the late response.
    i get many error messages, i took screenshots of 3.
    1) In the task bar, lower right hand corner of screen: the wifi bars have a yellow dot over them.
    I right click and pick "open network and sharing center."
    here is the screenshot of the error message i see:
    http://imgur.com/bpq9a8h

    2) When i double click the red X between MICHAEL PC and Internet, which you see in sceenshot 1, it tells me to "plug an ethernet cable into this computer"
    I skip this step.
    I go to "change adapter settings."
    this is what i see:
    http://imgur.com/VlkQjTd

    3)From sceenshot 2, I right click the Wireless Network Connection icon, and hit connect.
    It brings up a set of wireless routers in range.
    i click on mine: MICHAEL-PC_Network.
    Hit connect.
    Without asking me for a password, screenshot 3 pops up after 5 seconds.
    http://imgur.com/FFu9Z3D

    I disabled the wireless connection, unplugged the router and plugged it back in, and then enable it the wireless connection again.
    Still shows up "Not Connected".

    troubleshooter can't find any problems.

    I will be away for 2 days and cannot respond to any suggestions until monday, China time. I can receive messages, but I will leave my PC at home.
    thanks for helping me out.
    Michael
  41. In this case, try something else on Monday.
    Since you`re not requested for a password, you either don`t have one setup in the router settings (I doubt it), or you need to remove the WiFi from your list, and add it again.

    Try this:
    Windows 7

    Go to Start > Control Panel > Network and Internet > Network and Sharing Center
    Choose Manage Wireless Networks from the options on the left.
    Highlight the network from the list and choose Remove
  42. this exact same issue happens to me too. I managed to fix it:
    Find out the physical address of your network. Then make sure it is correct.
  43. hey guys,

    thanks for all your help.

    1) i removed wireless network, and then tried to re-connect. Still didn't work...

    2) I found the physical address of my network:
    FO-DE-F1-11-SF-C6

    But how do i know if this is correct?

    Michael
  44. Try to go into the router settings while connected via cable, and you should find one option that will replicate the MAC of the router with the one of the PC.
    Also, after this, reset the password for your router, delete it again from your PC, and try to connect.
  45. I ran into some trouble.

    I went into my router settings, and tinkered around. eventually, none of my computers worked.

    called up my isp, and he said my router was broken. Bought a new one. All the other devices work now, but my PC still cannot connect wirelessly.

    Any suggestions?

  46. Well, if you changed the password, all the other computers would need to be reconnected to the WiFi, because now it had a different password.
    I`ll be home in about 7-8 hours, so maybe if you`re available we can talk on Skype or TS to check it our.
  47. Thanks a ton.

    It's about 5:30pm in beijing, I will turn on my Skype around midnight and wait until 1:30am...hopefully we can connect then. My Skype address is chengmichael.beijing.

    Re: router: when I bought a new one, the ISP guy came and installed it, and then put in anew password. All my devices connected to the new router and password, only my pc did not connect wirelessly (although it does now connect by cable again.)

    Talk to you later, michael
