wah......... you use router and splitter, no wonder your signal
so poor, try and direct connection to your modem, i also suffer
from weak signal last night,
just direct connect to your router, take out the splitter, and plug
directly to the cable point, and you see whether it works or not,
you have a cable box ah?
imagine your router have one firewall, and you have one more
firewall in your computer, and try and ipconfig, and see whether
you can see your ip address or not
