    Seemingly without provocation, my Lenovo X220 has issues uploading data. The Dropbox app won't upload. E-mail attachments fail with a message claiming SMTP server timeout. Speedtest.net upload test fails. Other Java web apps requiring upload fail.

    The problem is specific to one machine on a local network attached to the same router.

    Possible remedies suggested by a search, such as installing the most recent network card drivers, disabling firewalls and Symantec, and a System Restore don't help.
