Im using a Asus WL500g hub which connects to internet from a cable modem.
im also using a wireless notebook.
sometimes when i download and it reaches high speeds of 100kb/s, the hub would usually stop working after a while. the internet stops working and i would have to turn off the hub and turn on to get it working.
i usually leave both modem and hub on 24/7.

is leaving it on for long time the cause of this or the high speed transfer? how do i solve this?
