Go and buy a router. Plug your existing modem into the WAN port and your computers into the LAN port. You could even get a wireless router and connect your upstairs computer wireless. Be sure to lock down your SSID (Wireless Access Point Broadcast Name) so your neighbors or people driving by don't get on and do bad things on your network.

So I really need help. I have a Linksys (WRT54GS) wireless router upstairs connected to the internet, printers, etc. and a Netgear (WGT624) downstairs connected to a desktop, xbox and laptop. I don't want...


More information is needed.
Is the 'WAN' port on the Netgear router connected to anything?
(cable-modem? DSL-modem?)

How many friends will come over at the same time?
How many 'LAN' ports are on the Linksys? How many ports are "free" ?
How many 'LAN' ports are on the Netgaear? How many ports are "free" ?
How many "spare" Ethernet cables do you have?

Is your goal to provide computer-to-computer connectivity,
or are you just trying to provide Internet access for everybody?

If you are "downstairs", is the wireless signal from the "upstairs" router strong-enough to provide wireless coverage "downstairs"?

If you are "upstairs", is the wireless signal from the "downstairs" router strong-enough to provide wireless coverage "upstairs"?

Trying to connect a wired network wirelessly to a router


No. You'll need to run a "cross-over" Ethernet cable from one of the "LAN" ports on the "downstairs" router, connecting to the "WAN" port on another router that you will need to buy, and place "upstairs", and connect the 4 devices to the 4 "LAN" ports.

Or, run a long "straight-through" Ethernet cable from your DSL-modem (or cable-modem) that is "downstairs", and move your wireless router "upstairs", and connect the 4 devices to the router's "LAN" ports.
Your laptop "downstairs" should still be able to connect (wirelessly) to the wireless-router that is "upstairs".

My internet keeps disconnecting


It sounds like the wire from your house to the isp switch is faulty you should probably call them down to fix. Or it could just be the modem are you using the same modem for both computers? If so then that's probably the problem.

Heating blowing coo air downstairs and warm upstairs?


Some of this depends on where the air handler/furnace is located. Most often in two story houses, it's in the attic upstairs, or in a closet upstairs. A duct routes air from the furnace to the downstairs supply duct, so it is a distance from the air handler.
When the unit first initiates a heating cycle, that duct is going to be full of cool air, and the duct itself will be cool. So the furnace has to run long enough to push the cool air out, as well as warm the duct up, before your going to feel warm air at the registers downstairs.

Keep in mind, heat rises. And, your thermostat only monitors the immediate area where it's located. In your case, upstairs.
Two story houses are problematic because of this. And one way around it is to have a damper system installed that distributes the air upstairs or downstairs based on a thermostat located in those spaces. There would be 2 dampers, and 2 thermostats (one upstairs, one downstairs). Each stat would control a damper, and the call for heat or cooling.

Let me know if you would like to consider a system like this, and I can point you to components to use. I've put several system like this in.

Problem connecting to my network


What I would do is replace the wireless router with a 4 or 5 port switch to control computers (devices) downstairs. Or, if you need wireless access, purchase only an access point to cover downstairs.

This way the wire from upstairs goes directly into the access point and you have wireless access downstairs.

And yet another way would be to purchase Airlink 101 PowerEthernet boxes ($54.99 each) and use those to connect an access point anywhere in your home that has an outlet.

ENTERNET CONNECTIONS FOR PS-3 80GB


if you want to be able to play your ps3 downstairs with your modem upstairs, you might consider buying a Wireless Router that has Wireless G , for your PS3.
This will allow you to access your Internet all around your house without wires. I suggest looking for one that features MIMO or range plus max, or anything else that increases your signal range since there is a fair amount of distance involved.

The alternative is relocating your modem downstairs and hooking it up to the PS3. BUT your computer wont have Internet.

check the ip addresses with the pc downstairs and see if all the pc's have the same default gateway. If not check your network card or network cable.
