Re: limited or no connectivity

When the limited or no connection comes up again, try right clicking on it and choosing repair. I hope this solves your problem

W fi will no longer connect

The wireless router has a rest button, just reset it, you will need to reset security, if you use it.

To rest ip, you use ipconfig/all

ipconfig /release

ipconfig /renew


But if you just reset router, repower this and the cable modem, you should see the wireless, then if you have to, open network and sharing, change adapter setting, disable and enable the wireless hardware.

My laptop is showing that I have excellent connection with my wireless, but wont connect to internet, ran connection diagnostics and it said problems with Winsock Provider Catalog, any help please....

To repair the Winsock catalog you will need to reset it back to its default state.

  1. Click "Start" and type "CMD" in the search box. Press the "Ctrl," "Shift" and "Enter" keys simultaneously. This action opens a Windows Command Prompt with administrative privileges.

  2. Click "Yes" on the permission dialog screen and the Windows Command Prompt opens. You should also see "Administrator" at the top of the window.

  3. Type "netsh winsock reset" next to "C:\Windows\System32" and press the "Enter" key.

  4. Restart your computer after you see the message "Successfully reset the Winsock Catalog."

After executing this command, you may need to reinstall the software for your network hardware.

I can not connect to my wirless local net work on my acer laptop what can I do to fix the problem? ( I was have a problem with avg free and it wasnt allowing anything to work on IE8 so i unistalled avg...

This should be a simple fix, do the following below.
1) Go to start, run, cmd, OK
2) After Cmd opens type this:-
netsh winsock reset catalog
--press enter

3) and again after pressing enter

netsh intip reset reset.log

4) Reboot

You should now be able to access the internet and your router etc.
After doing this go through and set up a new network, WiFi connection, using the icon, in the system toolbar, bottom right, click on the ICON, Right click, and select "Connect to wireless network" Select your network, if asked supply the WEP/WAP Key, password, and login, now you should be able to access the internet, through the router.
Also on laptop, in fact ALL "Clients" ie: Anyone who connects to the router. MUST have a Computer Name, a Windows login password, have sharing enabled, They also must have DHCP & Zero Configuration disabled in services. go, START>>RUN>>services.msc (enter), when the services window comes up, scroll down to DHCP, and turn OFF, set to Disabled, on start up, then, scroll down to Zero Configuration,and stop that and disable from starting too. Now reboot.

Dell Inspiron 1525 - No wired or wireless network

I suspect the Vodafone wireless adapter software is controlling the Dell wireless adapter. Start> in the search box type CMD
  • Reset WINSOCK by typing netsh winsock reset catalog
  • Reset IPv4 TCP/IP by typing netsh int ipv4 reset reset.log
  • Reset IPv6 TCP/IP by typing netsh int ipv6 reset reset.log
Next make sure the vodafone applcation is not running
Check you are getting a ip from the router by Start> in the search box type CMD
  • ipconfig /all
This will return a list of numbers - what you are looking for is a IP number for your wireless connection
A very useful tool to use for wireless issues is xirrus, If you can copy the program onto the PC thats not working and install and run, this test if your adapter is working and also will display all the networks broadcasting in your area. Which will prove the hardware works.

My ip will not connect with my wireless connection on my laptop. My internet connection says very good but my ip connection is disconnected. How can I fix it?

Hi, first thing i would do is a winsock reset, pretty much resets all your networking settings. Go to start menu, then click on run and type in cmd and hit enter. At the black windows type in 'netsh winsock reset' and hit enter. If it asks you if your sure you can type y for yes, then it will tell you to reboot the computer, so go ahead and restart. Next thing to check is your wep encryption code, make sure you actually check it directly from the wireless router you are connected to. The final thing to test is to make sure you don't have more than one wireless configuration utility program running at once. Go to control panel, administrative tools, services, go down to wireless configuration and make sure it is enabled. If you need anymore details to any of this please feel free to contact me directly, thank you.

Wireless connection keeps failing

I have a similar problem with my Linksys G router. It is putting out a weird ip address through DHCP. While this does not fix the problem, setting up a static ip eliminates it for now. If I ever find out the cause, I will post it.

Ip Address 169.x.x.x Wireless Internet Connection Problems 6400/E1505 Dell Laptop

questions to ask yourself:
- I the wifi card connecting to the routers wifi network? or your next door neighbors?
- did it connect with the correct WEP? withouot the right WEP it will not communicatwith the WAP
- is the router set to be the DHCP server? this function is normally defaulted to ON

some times though windows simply has to have its TCP stack reset after having been connected to too many different networks, especially if you are a heavy wifi user.

open a command prompt: I see you already know how.

Type this command line

netsh int ip reset <anyfilenameyoulike>.txt
the txt file will be a log file tha will be placed on your main (c:) drive after the NETSH command has run

next lets reset winsock since we are here in the command line anyhow

netsh winsock reset

if everything goes right you'll be prompted to reboot you machine.

hopefully this will solve your inability to aquire an IP address from the router.
