Router Stuck on Acquiring Network Address

by Joe Kraynak on May 31, 2010

I just changed routers from a Netgear to a LinkSys. One of my computers found the wireless network but could not connect to it. It was stuck on “acquiring network address.” If I chose to repair the connection, I would get the message “renewing IP address,” but the system seemed unable to renew the IP address. The computer would connnect to the router fine with a LAN cable.

What fixed the problem for me was to remove the wireless Netgear entry from my computer (PC running Windows XP):

  1. Click Start, Settings, Network Connections.
  2. Right-click the icon for the wireless network and click Properties.
  3. Click the Wireless Networks tab.
  4. Below Preferred Networks, click the entry for your previous wireless router.
  5. Click Remove and confirm the removal.

What happens, it seems, is that the wireless network entry for the previous router prevents Windows from renewing or releasing the IP address it was using so that IP address can be reassigned to the computer. By deleting the entry, you release the IP address and Windows can renew it for the new router.

If you try this solution, please post a comment to let me know whether it worked for you.

My wife was having trouble logging into her Novell Groupwise account at her school from home. When she tried to login, she kept getting this error message: Your login is not current. Please login again.

I tried clearing the browser cache as some have recommended elsewhere, but that didn’t help. The solution for us was to use a different DNS (domain name server). Instead of using the Wildblue satellite Internet DNS, we adjusted the network’s TCP/IP settings to use the DNS offered by OpenDNS, an alternate DNS (it’s free).

Change DNS in Windows 7

Here’s what you do in Windows 7 (and probably Windows Vista, too):

  1. Click Start, Control Panel, View network status and tasks (below Network and Internet).
  2. Click Change adapter settings (on the left).
  3. Right-click the network connection through which you connect to the Internet and click Properties.
  4. Network Adapter Settings

  5. Click the TCP/IP entry (below This connection uses the following items) and then click the Properties button (below the list). You may have more than one entry, such as Internet Protocol Version 6 (TCP/IPv6) and Internet Protocol Version 4 (TCP/IPv4). On my system, the one that has the DNS settings is the IPv4 one, but you may need to check both to find the right one.
  6. Click Use the following DNS server addresses if this option is not already checked. If the option is checked, jot down the numbers in the Preferred and Alternate DNS server boxes, so you can change back to the original settings if this doesn’t work.
  7. Enter the following DNS server addresses:
    Preferred DNS server: 208.67.222.222
    Alternate DNS server: 208.67.220.220
  8. Click OK and then click OK again to save your settings.
  9. Try logging into your Novell Groupwise account. If it works, please come back and let me know.

Change DNS in Windows XP

Here’s how you change your DNS addresses in Windows XP:

  1. Click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections.
  2. Right-click the network connection that you want to configure, and then click Properties.
  3. On the General tab (for a local area connection), or the Networking tab (for all other connections), click Internet Protocol (TCP/IP), and then click Properties.
  4. Jot down the existing DNS settings, whatever they happen to be.
  5. Remove the checkmark next to Obtain DNS server address automatically.
  6. Click Use the following DNS server addresses, and then type the preferred DNS server and alternate DNS server IP addresses in the Preferred DNS server and Alternate DNS server boxes, as shown below.
  7. Click OK to save your changes.

Now try it! And don’t forget to come back here and let me know whether this helped.

Windows Live Mail All Accounts in One Inbox

May 21, 2010

I have four email accounts. In Outlook Express all my email would pour into one Inbox. Very convenient. In Windows Live Mail, incoming mail for each account ends up in its own Inbox. Very inconvenient, at least for me. If you’re like me and you want all your email in one place, here’s what you [...]

January 5, 2010

Recently when my satellite Internet connection slowed to a crawl, I assumed it had something to do with the satellite. I called Wildblue. The technician ran a check, informed me that the signal was weak, and advised me to check for snow or ice on the dish. The dish was clear, so the technician assumed [...]

Convert docx Files

If you received a Microsoft Word document from a colleague or friend and can’t open it, it’s probably because it’s a docx file — the default file format starting with the release of Microsoft Word 2007. If you try to open the file in an earlier version of Word, you probably get a dialog box [...]

Weak Connection on Wireless Router? Try Changing Channels

October 24, 2009

Recently, while visiting friends in Denmark, I had trouble connecting my new netbook PC through their wireless router to the Internet. My host informed me that lightning had wiped out their system and they had to buy a new router, which didn’t seem as powerful as the last one. The signal seemed weaker. When he [...]
