Hi. I have a really serious problem with my new 24" Aluminum iMac (it's the latest generation). I have a Linksys WRT54G wireless router in my house. Every time I turn the iMac on or awaking it from sleep mode, the airport is receiving bad signal for like 20-30 minutes and the internet doesn't work, only after that amount of time, he gets full signal and the internet works. This computer is my work and I just can't work like that. I don't know what to do, some told me to take it to the lab but I can't, if I take it to the lab I will lose days of work and the closest Apple store to my house is 1.5 hours driving. Some told me to re-install the OS but it has so much material on it (backed up on time machine but still) it's just a stupid and long process and everything works good except for that. What would you suggest? do you think it's my router that does the problems? because I also have a MacBook who has no problems with it at all. Thank you very much I would really appreciate your help, I just can't take it anymore.
