No such problems on my laptops (X220, X201). iwn seems fairly solid in most cases so if seeing problems there I would check that the u.fl connectors are properly seated (if you want to try disconnecting/reconnecting to see if that helps you may want tweezers, they are a bit fiddly). The OP was about T40 though, which is much older. Any problems there (excepting hardware) are less likely to be related to problems seen on newer machines.
