Try these steps in order (if one doesn't work go to the next step):

1) If you are using wireless try connecting directly to your router.
- If fixed: Somehow losing packets over air.

2) If you are wired directly to the router try connecting directly to the modem.
- If fixed: Your router has a problem.
+ Try switching the port the cable plugs into.
+ Try resetting your router to factory settings.
+ Try upgrading the routers firmware.
+ Try a different router.

3) Try a different cat5 cable.

4) Try a different ethernet card.

5) Try a different modem.

Ok took a while to figure it out: Jumbo frames...
I enabled jumbo frames on my gigabit segment to get higher transfer rates.
Due to I dunno what Fortress (read: HL2) can't handle it proper somehow

I disabled jumbo frames on my firewall and client....
Result: IT'S ALIVE IGOR!!! ALIVE I TELL YOU

Thank you very much for all your support & tips
