Mam chyba ten sam problem. Uzywam routera marki Pentagram. Na laptopie wszystko dziala w porzadku, ale na pececie co pare minut pojawia sie spory lag. W Urban Terror np. pokazuje sie wtedy w rogu ikonka kabelka, jakby serwer tracil na chwile polaczenie z moim pc. U kolegi lag trwa 10 sec, u mnie pare sec.. Mam Viste x64 Ultimate.. Probowalem ponizszego sposobu, ale nie zadzialalo, chodziaz dostalem niezlego kopa w pingu.
