Windows 7 laptop wifi connecion issue
Boggin:
Can you go back to my Reply #7 and follow those steps to remove the SSIDs from the registry.
Disconnect the Ethernet cable before you reboot so that it has to try and wirelessly connect.
If DHCP still fails to assign an IP address then go Start - type services.msc - press enter then check the following services are showing as Manual or Automatic - the auto ones should also be showing as Started.
COM+ Event System
Computer Browser
DHCP Client
DNS Client
Network Connections
Network Location Awareness
Remote Procedure Call (RPC)
Server
TCP/IP Netbios helper
Wired Autoconfig is set to manual.
WLAN AutoConfig
Workstation
If a service is not running, click on it to highlight then click on Start (top left).
If it fails to start then right click to open its Properties and check the Dependencies and that each of them are running.
Any Dependencies not listed in services.msc can be found in Device Manager/View/Show hidden devices/Non-Plug and Play Drivers which is where I want you to also go to look for any yellow alerts.
With a laptop, the Wireless NIC is a chip attached the motherboard with its aerial cable routed around the screen.
With the opening and closing of the lid, cables can become damaged, but to see if your computer has a wireless interface, run a command prompt as an admin and enter -
netsh interface ipv4 show interfaces
You should get something similar to mine - I don't have Ethernet connected and I've changed my MTU to 1492.
Microsoft Windows [Version 6.1.7601]

C:\Windows\system32>netsh interface ipv4 show interfaces
Idx Met MTU State Name
--- ---------- ---------- ------------ ---------------------------
1 50 4294967295 connected Loopback Pseudo-Interface 1
19 25 1492 connected Wireless Network Connection
12 5 1492 disconnected Local Area Connection
If you have a wireless interface then enter -
netsh winsock reset catalog
netsh int ip reset resetlog.txt
ipconfig /release
ipconfig /flushdns
ipconfig /renew
ipconfig /registerdns
shutdown /r /t 00
and then see what happens after the reboot.

Ok, I'm working on, and so far the deleting the SSID "did" help, but I seem to still be getting the error, even though I'm connecting properly. Huh. I'll check the services out, but I'll let it be after that unless it keeps failing to connect. EDIT: The services were fine, so I'll do those commands if I need to. Thanks for all the help by the way, on this and my other threads! It is greatly appreciated. :cheesy:
Boggin:
Is it still disconnecting ?
Tacotardis42:
As far as I can tell, no. Either something I did fixed or it was a fluke. Eitherway, with an ehernet cable I won't need to go wireless. If I do experience wireless problems again though, I will try what you said out.
Boggin:
If you are close enough to the router and it's practical, then it makes sense to use Ethernet, but it would be nice to know that wireless connectivity has also stabilised.
