Hi guys. I just got my iMac refurb in the mail the other day, and it came with Mountain Lion installed. That's cool; I'm still on Snow Leopard on my MBP. The only problem is that on the iMac, the wifi at my house works intermittently. It really varies, but the wifi will disconnect often enough to be obnoxious. Yesterday it was every few minutes; right now it's every 5-10 minutes or so. I never had these kinds of wifi issue on the MBP/SL machine, and I see others specifically having this issue when having upgraded from SL to L/ML. I tried googling my issue and while I see others having this issue, I couldn't find any definitive answers (here in this forum, or elsewhere). I did check for duplicate keychain entries for my router, and that isn't the issue (only one password in there for the wifi). Could anyone point me in the right direction? Thank you, I appreciate it.
