Sounds as if the router is blocking.  Suggest entering the router setup
and VERY carefully checking all security sections making certain ALL
security options are disabled - even if you are positive they are
correct. It only takes one setting to cause your problem.  I am
especially suspicious since it doesn't work under Windows.  Once you get
it working you can then carefully add back security options minus the
one causing the problem.  Based on what you have told me I don't thing
it is either a Windows or Linux problem.  Good luck.
