I own three Apple products: MacBook Pro iPad iPhone They all disconnect from wireless networks after between 5-30 minutes of use....this happens regardless of which wireless network I connect to. I have tried changing the wireless channel (I am currently living in Europe, dunno if this may be part of the issue). The only solution is to manually turn off the wireless radios and turn them back on, which is getting very annoying... I'm pretty sure its not a router issue b/c as I said, these computers do the same thing in coffee shops, libraries, etc. Also, they are all up to date with software/firmware. Also, I did not experience this same problem in the US...has this happened to anybody or are there any ideas about a solution? Thanks!
