New imac! little help and advice

[ichabod crane]

ok so got my new imac and all is well pretty much, doing all i need and working well just two issues one major one minor.

imac 20" 2.4ghz 1gig

major issue the wireless settings keep changing themselve everytime i turn it on i set the wireless up and connect it, and it all works fine, but if i turn it off and then back on again all the settings in the airport part are gone and sometimes now it says error conencting. i have a netgear router and wpa key any ideas on this? i have tried inputing the details then locking the settings but on restart its just unlocked and all gone as if reset!

and minor issue is, its quite slow to boot up, first i get a grey screen with apple logo for a good minute of more, then it says startin OS X which can take up2 30seconds i know a little petty but i expected this to be quicker.

Thanks guys

Edit: also if anyone who can help me and uses msn would be much appreciated if they could add me this evening for some mac tuition!

Anyone, know the brand of memory as standard in the imac? cant seem to find out and dont wanna take it out at the moment. i know you can put seperate brands in as they dont support dual channel. but id like to get a matching stick

thanks
