Had just switched over to EE as my ISP, for the fibre optic broadband. Fast speeds, lovely. However, unlike any other wifi I have had, my MBP disconnects from it automatically if I leave it for a while. When I go back to the machine, it wakes OK but has not been connected, so emails have then to download, dropbox only then begins sync etc. EE say that it's a mac thing and windows machines don't suffer this. Any idea what settings I can check on the router or my network settings?
