I have a relatively new 13" MBP hooked up wireless to a time capsule and for the last 3 months all has been well ( good connection throughout the home). For the last three days as soon as I get upstairs i get network problems, drop outs etc. I haven't changed anything, all I can put anything down to is that I fully shut down my MBP early this week - usually put in sleep mode?? I have shut down and re started both the router and t/capsule. Incidentally, my older MBP and iPhone both connect upstairs to my network Thanks for any assistance.
