Ok...I just got a laptop for Christmas (yay) and I was able to access the internet over my wireless network fine with it. We've had this wireless router for a couple years now (a Netgear MR814) but we never really had a need for the wireless feature until now when I got my laptop. Well now that I had taken notice to the wireless aspect of my network I decided I should enable encryption. However, whenever it is on, I can't connect to the network (fully) anymore because I'm getting the limited or no connectivity error, and it is saying it is because my router isn't assigning me an ip. DHCP is enabled on my network so it should just do it automatically...and it seems to be only when encryption is on that it isn't assigning it...anyways I have no idea what to do...maybe I should just enter the ip information manually in my wireless card settings instead of having it obtain it automatically?

Did a Google Search for you. I don't use a Netgear. But I thought I would suggest reading the setting up of a wireless network/connection from your particular modems manual. Might be something basic there you have missed.

What type of encryption are you using anyway.

WEP,WPA or WPA-2

It's WEP encryption, both 16 and 128 bit, it doesn't matter which.

I have had a similar problem with my netgear router and in the end used no encyption.

Three things you can try..


1.

Windows XP SP2 Update KB917021 was published on October 17th 2006. What's that you say?



It's an update to "help prevent the Windows wireless client from advertising the wireless networks in its preferred networks list". Those of you that travel with confidential information might want to investigate this patch. It wasn't included in Microsoft's monthly updates.

Advertising the name of your preferred networks creates the potential for a man-in-the-middle attack. This patch won't stop your Windows notebook from using a spoofed network, but it will fix it so that the hacker would have to guess the name.
