I have cable internet and it runs through a wireless router. My conection has
gotten very slow as far as loading websites etc. So I decided to take the router
out of the loop and go direct from the modem to the computer. When I did, I had
no connection. A network check showed nothing connected. I have loaded software
for the router. Does taking the router out of the loop constitute a new network
as far as Windows 7 is concerned and I have to set up something new? Thanks.
In General--
Cable Modems have an Ethernet connection, and often a USB connection.
Wireless Routers may have both multiple Ethernet connections and
(obviously) wireless connections.
The IP may only allow/provide one address via the modem. The IP may
further restrict use to one user MAC address.
Your computer and/or the router supply a MAC address on demand to the
modem when connected to it.
The wireless connection from your computer is quite different from the
Ethernet connection.
Most Wireless routers (but not all) have both Ethernet ports and
wireless ports. The Ethernet portion may have (commonly) One connection
to be used to connect to a cable, modem and four others to be used with
computers, etc.
I don't know how your win 7 computer was setup for wireless use, but the
Ethernet setup is different, and uses a different physical interface. So
you will need to set it up also.
The MAC address on many routers can easily be changed to get around the
IP allowed MAC address issue. Fortunately, this is something that is
becoming less common.
The router Ethernet setup is generally accomplished first, and then the
wireless setup.
Router software is generally not needed, although it may be for initial
setup or firmware updates and configuration backup.
The cable modem usually has a different IP address than the router. This
can be part of your problem. If the customer side IP address of the
modem is the same as the router, you will have problems using the
router, and generally need to change the address of the router.
