Someone on the Dutch computer webforum gathering.tweakers.net (article:
http://gathering.tweakers.net/forum/list_messages/1069142/last) posted a new
Annex B beta firmware 1.01.14. It's for Europian (Dutch) users. The file is
provided by the Dutch Linksys supportdesk. Hint from the supportdesk: set
dsl modulation on g.dmt.

The poster has posted the firmware here:

The poster said this firmware fixed his FTP upload problems with the
original V2 firmware and is working fine.
