Latest Acer driver working fine, Comcast router working fine, did all the remedies on the web except the rasppoe.sys driver change (laptop says no, even in admin mode). What am I missing? Broadband works fine on my Thinkpad with its Broadcom driver.

    Can you provide a bit more information about how you are connecting?

    Are you using a router or access point? 

     

    Also, you may wish to share what you mean by "broadband":  DSL, cable, T1, T3, fiber?

    I'm using an Ethernet cable from the Comcast router to my miniport. The approved driver for the Acer laptop is Qualcomm Atheros Ethernet, computer says it's fine. "Can't find valid IP address" is the response, when Comcast says the router is fine (and works fine on my IBM Thinkpad too.)

     

    Now of the dozns, many official Microsoft, remedies I found on the web, the two major ones left are these below. Welcoming feedback, but I'm hesitant to try these as I'm not a computer set-up expert.

     

    extract vista rapppoe.sys file
    (I don't think it's this as I have an old Acer laptop running Vista and it too has the same "can't find IP Address" problem as the new Acer.)
     
    command ip
    Just a question, Have you tried to release and renew your ip address, and have you gone to the command prompt and typed " ipconfig " to see if you have an ip address. Also, at the command promt type " ipconfig /release" hit enter, then type " ipconfig /renew" then hit enter again. Hope this helps. 
    When you went into the networking-tcpip -properties, did you check " Obtain Ip automatically ". Just wondering if this reply applies with your problem.

    The Comcast router is connected via ethernet cable to the ethernet port on the Aspire 5253.

     

    You may wish to compare the configuration on the Thinkpad to the configuration you are attempting to use on the Aspire for the connection.

     

    The "Can't find valid IP address" error is pretty generic, and that will make it difficult to diagnose.  Where does this error appear?  In what window?

     

    Are you attempting to use PPPoE or allowing the router to use DHCP and assign an IP to any system connected to it?

    Set-up is a near duplicate of the Thinkpad, I just unclicked one box, but no difference.

     

    Here's what I'm doing.

     

    I. Click Internet Explorer ICON, says I'm offline and make sure work-offline box is not checked. Still no access.

     

    II. Left click internet ICON on Acer 5253 taskbar

    A. I'm given a selection of ways to connect. I choose Broadband 3, which is the name I entered

    along with my IP name and IP password given by Comcast. It asks me to confirm the password.

    B. Error code 651 appears. Already investigated that nightmare, results given in my original post.

     

    III. Right click internet ICON on Acer 5253 taskbar

    A. Click "troubleshoot problems" option in balloon

    B. New window appears: WINDOWS NETWORK DIAGNOSTICS

    1. Message flashes that it's "Resetting local area connection" and "Resolving problems"

    a. I'm asked to reset my router by unplugging it. I already did that before

    calling Comcast last week and they said the router is fine. So I click "skip step"

    b. the DIAGNOSTICS window concludes (again): PROBLEM: "Local Area Connection" doesn't have a valid IP configuration

     

    iV. Right click internet ICON on Acer 5253 taskbar

    A. Click "open network and sharing center" option in balloon

    B. In new window, diagram says This computer-> Unidentified Network-> X Interenet

    So, along the left column I click "Change adapter settings"

    1. Broadband Connection 3, WAN miniport (PPPOE) is checked, but reads "Disconnected"

    Also, Local Area Connection, Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller reads

    "Unidentified Network"

    a. I right click the latter for properties, and it says, under Device status, the Qualcomm adapter is "working properly"

     

    So, again, my router is fine and my Acer-approved driver says it's fine, so what's the deal with neither of my Acer laptops being able to connect? The people at Comcast are all confused over what an Ethernet connection is and keep asking me about wireless network connections: I keep telling them I'm using a "cable" and besides I'm in the Ogden wildereness where "no wireless hotspots are detected" anyway. I had to wrestle just to get my IP name and password!

    I appreciate you taking the time to communicate all of that information.  I think we're making some headway.

    There are a couple of confusing things to me, that I'd like to try to get straightened out.

     

    The Comcast hardware ... is it a router or a modem?

    If it's a router, you should be able to make it connect with the PPPoE connection and serve DHCP IPs to any computer connected to it, instead of attempting to do PPPoE connections with each computer.

    If you have a hardware model, I'd be happy to help you figure that out.

     

    If it's a modem, it may be easier to attach a router to it and do as I suggest above. 

    Let the router make the connection to the Internet service, and then serve IPs with DHCP.

    It's a modem. So you're saying Acer laptops REQUIRE an external router? Where can I get one and how much will one set me back? :cringe:

    I do not believe that I ever stated that you require a router, no.

    It would likely make your situation easier, instead of having to connect each individual computer to the modem when you want to make a connection, but that is entirely up to you.

     

    I'm going to read over all three scenarios that you lay out, above, and see if I can make any suggestions.

    PPPoE is fairly straightforward, but there may be something that is getting missed.
