Windows 7: Wireless takes too long to connect (DHCP server)at startup?

Wireless takes too long to connect (DHCP server)at startup?

I would like to ask for help

I'm having a issue with the wireless in the past couple of days before it has always connected in seconds. when starting up the laptop it takes 1-2 minutes to connect (blue circle loading) but the connection is not stable such as random times disconnects (turns off itself) and the signal strength is pretty weak(looking at task manager 10-15mbps). Once the wireless stabilize which is around 15 minutes it can reach back to normal speed.

I went into the event viewer and noticed the laptop has this warning message + error message

Error message: The IP address lease for the network address 0x001D0981E03A has been denied by the DHCP server DHCP server sent a DHCPNACK message).

Another message:Router Advertisement settings have been changed on the network adapter 13. The current M - Managed Address Configuration flag is false and the O - Other Stateful Configuration flag is false. User Action: If you are seeing this event frequently, then it could be due to frequent change in M and O flag settings on the router in the network. Please contact your network administrator to have it resolved.

Hi there
If the signal is weak --get a Wi-Fi extender.
You might also be getting contention from other people in the neighbourhood -- Broadband rates are fine when it's only you but in urban areas (London, New York etc) a LOT of people are connecting to probably the same ISP and you will get degradation even on Optic cable if you are using wireless.

Re-boot the router as well and change the channel and protocol -- use N if you can as it's faster and newer -- a lot of people won't be using that protocol yet. Your computer's Wi-Fi card if it's new(ish) should be able to handle the protocol.

Windows 7 64-bit

Sounds to me like you have an IP conflict somewhere. Do you have your laptop set to a static IP or is it assigned? Have you messed around with your router settings, assigning IP addresses and what-not? It's pretty easy to create a conflict like this.

After your laptop connects with this issue, click on your WiFi Icon in your Notification bar then right-click on your actual connection and click Status. In the window that comes up click on details and check what your IPv4 address is. If it's coming up 169.something, then there is a conflict/problem. Post what your result is.

How many computers on your network? Do you have them all set to auto get IP or are they set to static numbers?
