WLAN access rejected

[Continum]

Hi.

My WiFi drops down to limited connection randomly. If I turn wifi on and off I get connected back up. This can happen multiple times each day.

I looked into routers event log and found this:
[WLAN access rejected: incorrect security] from MAC address <my mac adress>

In the log I can see this multiple times as well:
[DHCP IP: <my ip>] to MAC address <my mac adress>

So it seems like the router rejects my laptop access and then suddenly it goes through.

If anyone could help me out here, it would be much appreciated.

Router: NETGEAR WNDR4300
Wireless card: Intel Centrino N-2230

Have you updated the firmware? Try that first.

My apartment is rental and I do not have access to the router. My landlord is currently on vaction, so no way to connect with cabel. How safe is it to do a firmware update on the wifi?

Forgot to mention that it works for the other laptops in the apartment. Occurs only on my laptop, but when I'm at school, it works just fine.
