I have a BEFSX41 v2 and a 5 port switch. There are normally 4 computers powered up and a small print server. With the addition of another computer, the performance of the network becomes unacceptably slow with frequent time-outs when loading web pages. How can I fix this or improve performance? Or do I have to get an 8-port router? Or would a 10/100/1000 router with 4 port handle my network plus an Xbox360 and perhaps network storage with a reasonable performance.
