I have a wireless network established in my house with 3 latops accessing. Two of my laptops (IBM and HP) can access the internet with no issues. The third (Compaq Presario) did work once upon a time but has stopped doing so. When the laptop starts up it quickly detects the router and starts connecting. It spends a minute or so "acquiring the network address") - it then gets a "limited or no connectivity" message briefly before changing to 'Excellent'. Interestingly the connection speed on the Compaq sits about 2mb whereas the other laptops connect at 24mb to 54mb. Addtionally, Skype can connect every now and then (the system tray icon turns green) and very occasionally I can bring up google - it suggests there is some connection but it is completely unuseable.
When I access the router web page all 3 latops are showings as DHCP clients on IPs 192.168.1.2 thru .4. The Compaq is the latter connection. They router is set to dynamically allocate IPs and the TCP/IP settings on all laptops appear to be correct (obtain IP / DNS Automatically).
I have scoured this (and other forums) for a few days and tried several things. I've seen several helpful people provide excellent advice in this forum and am hoping someone could do the same for me.
im tring to conect to the internet via my wireless router but all I get is status conected at 54mps exelent signal you are conected acquiring network address but it never gets there it just sits there but never conects to the internet ?
you may have a DHCP problem - DHCP gets the IP address from the router - to test this assumption you can enter the following address for Google http://74.125.95.99/ in your browser. If the browser does in fact connect to Google you can use the following steps to help resolve the problem. I have had mixed results with these tools and can't guarantee anything:
the first thing to check is NetBIOS over TCP/IP
>> Open up network connections (In Control Panel)
>> Right click on your network (Your wireless connection)
>> Click Properties
>> In the General tab click Internet protocol (TCP/IP)
>> Click Properies
>> Click Advanced
>> Click the WINS tab
>> Click the Enable NetBIOS Over TCP/IP button (This is NOT the default option)
The next item to check is the DHCP service itself:
click on start, run, enter 'services.msc'
look for DHCP client¦.
if it says acquiring network address that means that the dhcp client is DISABLED OR STOPED highlight the
DHCP client and on the left side you will see START the service, click on it and then it will say STOP,
RESTART then double click on the service and on the startup type select automatic, apply
Symptom
DHCP Client Service may not start automatically. When you attempt to start the Service manually, the
following error may be displayed:
Error: Could not start the DHCP Client Service on local computer
Error 1068: The dependency service or group failed to start.
Resolution
The DHCP Client Service in Windows XP, depends on these three components:
* AFD
* NetBios over Tcpip
* TCP/IP Protocol Driver
If one of the above drivers fail to start, then the DHCP Client Service may not start.
Step I - Make sure that the three driver files are present
Open Windows Explorer and navigate to /Windir/System32Drivers folder. Make sure that the following files
are present in the folder:
* afd.sys
* tcpip.sys
* netbt.sys
If one or more of the above driver files are missing, extract them from the Windows XP CD-ROM or from the
ServicePackFilesi386 folder, whichever is the latest version.
Step II - Verify the number of Dependencies
From other sources in the Web, I've found that some versions of Norton Antivirus (NAV) adds an entry to the
DHCP Service Dependencies, and removing NAV does not remove the appropriate value from the DHCP
Dependencies.
To quickly determine the Dependency services for DHCP Client Service, type the following command in Start,
If additional entries are listed under DEPENDENCIES
If any other additional drivers or Services are mentioned in the DEPENDENCIES section, you need to remove
them via the registry. Follow these steps:
* Click Start, Run and type Regedit.exe
* Navigate to the following branch:
* Backup the branch to a REG file
HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Dhcp
* Double-click DependOnService MULTI_SZ value and set it's data as follows:
Tcpip
Afd
NetBT
* Close Regedit.exe
Step III - Verify that the Dependency Service / components are running
Next step is to verify that the three dependency components are running. As the three components are
actually the Kernel Drivers (Driver Service), you need to manage then via the Device Manager. Follow these
steps:
* Click Start, Run and type DEVMGMT.MSC
* In the View menu, click Show hidden devices
* Double-click Non-Plug and Play drivers section
* Double-click the entry - AFD Networking Support Environment, and click the Driver tab
* Set the Startup type to System.
* Start the service. Note down the error message if any.
* Similarly start the two other drivers namely:
