Intermittent Connectivity:

NOTE: Before following the steps in this article, check if your wireless computers have stable connection when connected to other wireless networks (hotspots).

This article assumes that all wireless computers are experiencing intermittent wireless connection with the Linksys router.

Frequent wireless disconnection can be caused by different factors such as:

1. Wireless interference within the network.
2. Wireless settings of the Linksys router are still set to default.
3. Firmware is corrupted.

Reducing Wireless Interference

If you are experiencing frequent disconnection from the wireless network, it helps if you check the following factors, all of which can greatly affect your wireless signals:

your cordless telephone system (or even your neighbors'), or other nearby equipment. Try to change your router's channel to 1 or 11 (the default channel is 6) and restart the wireless computers.

Physical obstructions: Your router or wireless computers may be losing connectivity because of physical obstacles such as walls and floors. Try to move the equipment to different locations to find a better link.

• Placement of the router: Linksys suggests that you place your router as high off the ground as possible. When placing the router in a high location, leave a distance of two feet between the router antenna tips, ceiling, and wall. If your signal passes through multiple floors, place the router on the upper-most floor, and high up in the room.
• Surroundings: Keep the router away from large metal objects, bodies of water (fish tanks, bathrooms), and any electrical equipment including television sets, microwaves, radios, etc.

Customizing Wireless Settings of the Router
Having default wireless settings on the Linksys router may cause conflict with other Linksys routers within your network range. Linksys suggests changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.
NOTE: If the wireless connection remains unstable after performing the steps above, upgrade the router

Yes this is possible.. just configure the old router as a plain access point.

Upgrade the firmware of the router and use the channel 11 for the wireless connection.

Wireless broadcast is usually the first thing to go when a router is failing. How old is your router? Try these steps:
Turn off computer
Remove power from router
Remove power from modem
Wait 2 minutes
Restore power to modem
Wait for modem to boot up and gain all signals
Restore power to router
Wait for router to completely powerup
Watch for wireless indicator light
Boot up computer, verify your wireless network is broadcasting
Connect

If you still can not get the wireless network to access the internet, try connecting your computer with an ethernet cable. If everything connects fine and you can access the web, it might be that your router is going bad and needs replacing.

Try running the ethernet cable from the modem to port #2 on your router. Then run the second cable from port#3 on the router to your computer. This effectively uses the router as a pass-thru and bypasses all its functions. If you are able to access the internet this way, you need to replace the router.

You may have an IP conflict. Renew the IP on both the Sonys
At a command prompt,
ipconfig /release
it will come back with all zeros

ipconfig /renew
It should pick up a new IP address.

Try to reset the router for 20 seconds. There's a reset button at the back of the router. Just press and hold it down for 20 seconds, then unplug the power for 30 seconds, the plug it back in. Now try to reconnect to the Linksys wireless network.

This is what I would do I would connect the wireless to the internet direct and allow all PC with wireless capabilities to access the net through that wireless irrespective to where I place the wireless router.  Alternative I would link the cable on on the second floor the one you use for the PC to access the net to access the the wireless it should automatic allocate IP addresses as each machine accesses the network.  The speed of that wirless is decreased as each wireless PC comes on line.
