Problem undefined

Woke up this morning, and again I'm still getting kicked out of my Yahoo! Messenger and sometimes I also have to click on Reload several times until I can reach some webserver.  So I called quite angry to the ISP's help desk.  I'd called them two days ago, and left them my phone number, but they'd failed to call me back.

I had to wait a long time before a human being finally answered.  The girl took very well my bad humour, and offered to send a technician to my apartment and check my computer and the wiring in the building.  Well, I know there's no problem with my laptop computer cause when I take it to my office, I don't experience this problem; and I don't think it's the building's wiring either cause this building is much newer than the one housing my office.  But okay, I accepted her to send me somebody.

Surprisingly, the technician arrived the same morning, perhaps some three hours after my phone call.  That was quite something.  Then the technician was a rather nice lad, and even spoke some English.  He checked all of the wirings and stuff, but didn't find anything bad.  I told him the problem only happens in the evening.  He can't figure it out, especially since the connection is working fine right now.

Conclusion, if I experience problems again, please call again their help desk.  Doh!
