Well, I went a few steps further today.
I was using this code:

http_connection = Net::HTTP.new('site').start()
headers ={}
headers['User-agent']=HEADER_USER_AGENT
headers['Authorization'] = 'Basic '+ ["#{user}:#{pass}"].pack('m')
resp, data = http_connection.get(thePage, headers)

It's actually the same if you take into account that
["#{user}:#{pass}"].pack('m') adds a \n at the end of the string.
So we need to use ["#{user}:#{pass}"].pack('m').chomp (or the base64
encoding module - much better).
It still doesn't work though.
I switched to http-access2 (by Hiroshi Nakamura) and the following code
works:

headers ={}
headers['User-agent']=HEADER_USER_AGENT
headers['Authorization']='Basic '+ ["#{user}:#{pass}"].pack('m').chomp
#this is the standard request with the require fields
request = "/somepage"
uri=SERVICE_ADDRESS+request
clnt = HTTPAccess2::Client.new(nil)
resp = clnt.get(uri,nil,headers)

The only difference I can see is at the ammount of data that are sent
during the request (and the missing content-length: header for the
Net::HTTP request). The Net::HTTP does not send the headers immediately,
but does it in a Continuation packet afterwards. Can't say I understand it.

The new problem I have is that http-access2 does not handle wrong
passwords gracefully.It bombs out with  'Unexpected EOF' when reading
the headers of a 401 Responce. At least with Net::HTTP the error was
'401 "Authorization Required" (Net::ProtoFatalError)' and it was easy to
handle it.
Well, I did try your code too - It still doesn't work :(.
And I guess it's the router's fault, because I just used it on a proper
server that required authentication and it worked fine. Damn, I hate it
when hardware screws up.
