Hi. When connecting to the wireless network with my mums n900 it would flash the wifi status bar icon & then give up throwing up a "Network error". I already new that I had enable MAC address filtering on my router. This whole issue caused mums n900 not to connect. You would say well that's logical. Well yeah! but my n900 connects to my router even though it's mac address isn't in the MAC Address filtering list. Figure that out! lol Anyways if someone can explain that please do otherwise I'm off to enjoy some wifiying with my mums n900, buh bye. I hope this helps!
