Hi, I need to buy a new wireless router. I've got cable internet access so I don't need an ADSL modem, I'm based in the UK. I bought a TP Link WR1043ND earlier this year but it kept dropping the signal - oh and every time I turned it off it lost the settings for the attached usb drive. I'm now thinking about buying the Buffalo WZR-HP-G300NH, but I'm also considering buying something dual-band instead in case the TP Link's problem was interference from other devices. I've not found anything that tells me whether the airport card inside my mbp - new in March 2010, 17" model - will connect to a 5Ghz signal. There's not much point in me spending the extra cash for a dual band router if the MBP can only connect to 2.4Ghz! Does anybody know the answer? Basically, I want something fast, secure and with a USB port so that I can stick a drive on for on-site backup. I'm not really keen on paying the extra for the Airport extreme kit, nice though it looks. Thanks in advance.
