Trouble running CAT5 cables for my old house?

Go through closets to minimize drywall cutting. Or you could by a very long drill bit that Electricians sometimes have for this purpose. Also, Wiremold makes a baseboard trim that can be used as a conduit for cables.

It's easy. You take the Cat 5 cable back to the store and buy a wireless router.

The proper tool is called a "bellman's bit" About 6 feet long and flexible. Available in various hole sizes. Cut your opening for the j-box,(needs to be about 2 feet high for bit access, they are not THAT flexible) Run the bit up the wall, drilling the fire block and the double top plate. (leave the bit in place in the hole just drilled) Now go up to the attic and hook a pull string (or the cat 5) to the hole in the end of the bit and pull away. The bit should track along the opposite side of the wall cavity if at a shallow angle (careful here) It should also slide by any insulation but be careful of bit wind-up. Get a big knot of insulation on the end and you will play hell getting the bit back out. Tapered end bits rather than auger type (which are available)are less likely to snag.

Security is an issue if your brokerage password or bank account password get stolen.

Dear All, Thanks with all your helps. CAT5 is only one of the cables, I also planed to run telephone, TV cable and stereo wires on the same route. Thanks again, Hugh

if security is a concern, the routers have security that is quite simple to set up. You can limit access to specific hardware (network or hardware addresses). Am I missing something here?

They cant get stolen if they arent stored on the computer

Nope youre not. The point is the security is there if you choose to use it. You only mentioned the router. There is also security built into the wireless components. Various types of wireless encryption as well as MAC filtering. You use them your secure. You dont, youre not.
