Well, that didn't go as planned due to a Windows update failure. Then, the (not changed) router seems to have some sort of problem and either fails to connect at all or restarts itself every so often.
What is more of a problem though is that my U/S sync is 5347 but actual U/S speed via TBB, usually ok, is consistently a whopping ... 450k
Edit: seems the newer TBB speedtester is consistently completely wrong! The Flash one gives the expected result of ~5000kbs as does FTP and also a large HTTP file upload.
