Poor internet connection

Hi there,<br> after having two hickups (connection broke down twice for some days / weeks) in the beginning of the year my internet connection was doing good - means watching the news in the evening and working from home over VPN was normally possible w/o major problems.<br> Since three weeks (might be coincidence that at this time a Telkom technician was working on the cables in our garden, but might be not) the internet connection quality is very poor. Skype sessions with colleagues are not possible anymore and news streaming does not work at all. Can somebody please help!<br> Kind regards<br> Jens
