System: WinXP Professional Version 5.1.2500 Service Pack 3 Build 2600
Internet Explorer: Version 7.0.5730.13

Recently purchased refurb. Installed my internet service software. First couple of times it connected fine. Third or fourth time around whenever I tried to connect Internet Explorer either would connect to a cached older version of web page or else would refuse to connect and gave me this message:

Webpage unavailable while offline.

The webpage you requested is not available online.
To view this page, click connect.

- Connect - Stay Offline

Only problem was: I was online. My connection was good and my software confirmed the connection. After several tries, I disconnected completely, then reconnected using a new phone number. Suddenly everything went back to normal and I was able to connect normally again.

Story over, right? Nope... guess what? A few days later, I started getting the same error message with the new number. Solution: disconnect, then dial-up using another brand new phone number. Now my connection works again... for the moment.

I've run AVG and the latest versions of SuperAntiSpyware and MalwareBytes. They all claim my computer is virus and adware free. (The only glitch are some cookies installed by my internet service. The programs don't flag this as a serious threat, though.)

Advice?

No. Try not. Do... or do not. There is no try.

Intel only makes that chipset, who made the modem?

Sometimes a modem connects too aggresively and can't retrain down to a speed where it can hold the connection.

We always tested by disconnecting all other devices from the land line and then reconnecting one by one.

Cordless base stations are notorious for interference, cable routing is critical, I had a surge protector that kept messing me up.

Sorry, I don't know who made the modem -- it came preinstalled.

Don't have a cordless base station -- I don't even know what that is. :thumbsup:

If it was an overaggressive cable modem, why would switching from one phone number to a number solve the problem? And then why would the same "fix" not work the very next day? (I should note that the numbers are all configured for the same connection speed.

Oops... another potential important clue I neglected to mention (or not):

When I first boot to WinXP, I get a message in the lower right hand corner, just above the task bar, stating that my firewall is disabled and that I should click in the pop-up box to enable it. However, if I ignore the message and check my firewall the old fashioned way, Windows tells me that my firewall is enabled. In short, the pop-up says firewall down, while the firewall itself claims it's on.

Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.

If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.
