Internet is slower all of a sudden..

[Mark]

A standard LAN connection, (Ethernet) is 100Mb/s. That's normal. It relates to internal, LAN speeds eg. you won't get 100Mbp/s from the internet but you're likely to achieve that locally, like i can transfer files locally to my file server at around 80Mbp/s. Wireless is a lot slower with Wireless G being a max of 54Mbp/s which you'll never achieve.

How many people are on your network?
Have you tried it with just you on the network, on your ethernet PC?

I assume you've also power cycled your router? Turned router and modem off for 2minutes, then turned the modem on, then the router, then the PC. Still the same problem?
