After buying a new router it connects to my network fine it just wont stay connected. i do have 4 uniden 5.8ghz cordless phones, a microwave. its just some other networks it doesnt connect with. And actually I do hav ea wireless printer but it is functioning perfectly.
Are you losing your wireless connection or is it showing connected and the internet just won't connect?
If the airport card is not staying connected it could be that you are getting interference. Do you live in an apartment? You have to consider interference from your neighbors as well if this is the case. I wouldn't think that the phones would make a difference but the microwave definitely with boot you. Some of the lower GHz phones will too though.
I would go into the preferences for your printer by typing the IP address into your browser for that printer and make sure that it isn't using an address that is within your DHCP range. It could be booting your connection.
Finally, I would call your internet provider and make sure that there isn't something wrong with your Cable/DSL modem or with them no assigning a new IP address. It could be very well that the problem is on their end.
If all of these fail then it could be your Airport Card in your Mac. However, since you are getting a connection, I doubt that it is.
I'm surprised that you are having this much trouble with your local Apple Store. I have always gotten top notch service there. As suggested above, I would call customer care and make them send you a box to ship it. Take pictures of the condition of your Mac before you send it just in case. Be warned that you might be Macless for a while if they can't duplicate the problems that you are experiencing. Once their customer care has it, just call a couple times a week and make sure that you document who you speak with and what they say on the calls. Also, if they try to send you back your Mac without any repairs, refuse to accept that and tell them that you don't want it back until all of the issues that you describe are corrected. Most of all be polite and calm, and you will get farther with customer support people. I know this probably goes without saying but you would be surprised how people treat customer service reps... I got my girlfriend's dented case on her Powerbook fixed this way even though it is against Apple policy to fix cosmetic issues...
Goodluck
