I´ve got a problem and I was wondering if anyone out there could help me please???
<BR>
<BR>I have a network at home of two computers both running 10/100 NIC´s and a crossover cable to connect them. Sometimes, the computers can transfer data very quickly.. 600Mb in 3Min and sometimes very slowly.. 100Mb in an hour. What am I doing wrong and how can I fix it please.
