Hi, My router suddenly stopped sending out wireless signals- the little 'antenna' icon goes blink-blink a couple of times and then goes off. I don't k now if the wired connections will work because I cannot test it. Please help me resolve this problem.

Things That Affect Wireless Router Signals 1. Many wireless routers are using the same wirelesschannel. Many manufacturers choose channel 6 as the default. Change to anotherchannel.2. Analogue video senders used to send audio and video toother TVs in the home.3. Microwave ovens emit interference in the 2.4GHz band.4. Wireless speakers and console controllers can causeinterference with the wireless router.5. Bluetooth devices, newer Bluetooth devices can jump todifferent frequencies if there is a connection problem.6. Power cables located near the wireless router can causedropouts and speed reduction.7. Fish tanks will cause massive Wi-Fi shadow on the otherside of the tank from the wireless router. 8. Depending upon the location of large mirrors will reflectwireless signal away your computer.9. Building materials will block wireless signals such asplasterboards with metal foil, reinforced concrete walls and floors. Alsoobjects near the wireless router such as metal filing cabinets and otherelectrical appliances. 10. Blinking Christmas lights can reduce Wi-Fi performanceby 25% when it is close to the wireless router.
make sure you turn the wireless switch on. It should be on either side or the front of the laptop.
Did you configure the new router and set the wireless on it?
If your internet provider is a phone company such as AT&T did you configure the router to be PPOE (and set the userid and password) and bridged the modem that goes into the router?
If your internet provider is a cable company did you set the router to be DHCP?
Does the Sony even see the wireless network in the View Available Wireless Networks list?
Did you put the wireless key in correctly?
You didn't by chance happen to hit the FN function key on the lower left portion of the keyboard + the key (F1 thru F12) that toggles the wireless on and off? The correct F1 thru F12 key to hit will have the wireless signal icon )))) or it will have the icon of a tower with the wireless signal )))).
Power cycle the system by shutting it down and switching it on after at least thirty seconds. Check network settings to verify the IP address and other related information. Determine if the network card is working adequately. Identify the malfunctioning adapter by disabling the cards one by one. Move one of the portable hosts--such as a laptop--closer to the router. If it works better, interference or low signal strength is the reason for poor Internet access. Inadequate signal performance can be caused by several factors including cordless devices working within the frequency range (2.4 GHz) of a wireless network, shiny surfaces and too much distance between hosts and access points. Resolve this issue by using a wireless repeater?a device that amplifies wireless signal so it reaches distant areas within the premises. Minimize signal interference by maintaining a distance of at least one meter between cordless devices and the router. Alternatively, buy gadgets that function at frequencies other than 2.4 GHz. Try changing the WiFi channel for better results. Check the functioning of wireless router and access points. Adjust the router antenna to get an optimum signal. Most wireless routers come with omni-directional antennae to send signals in all directions, a situation appropriate for a square-shaped network. If hosts are arranged in a linear fashion, use an antenna that sends signals only in one direction. Some portable routers have internal antenna, giving more freedom to users who are on the go. Use an external antenna with such routers. The market now offers antennae with varying strengths, implying some are more powerful than others. See if using a more powerful antenna fixes the problem. Aside from increasing the range of transmitted signals, the reception capacity of hosts can also be enhanced. External WiFi-enabled antennae attached to laptops are now available for this purpose. Change the location of the router and access point. They should ideally be placed centrally between all computers. As the signal bounces off smooth and shiny surfaces, routers and access points should be placed away from windows, doors, mirrors and other metallic surfaces. Examine signal performance by using the monitoring utility that typically comes with the access point. Check that the devices show correct lights. Device lights are an indicator of accurate connections. Different lighting patterns indicate different things. For example, some network cards show green light on successfully establishing a connection. Similarly, the router's wireless LAN (WLAN) light is turned on at all times, even if no device is connected to it. Further, this light blinks when a host communicates with another host. Unexpected lighting indicates a problem. Go through user manuals to get familiar with this feature and make sure the devices show desired lighting behavior. Use wireless Internet utilities to check the SSIDs and channels neighboring wireless networks are using. Change your network's SSID and/or channel if they are the same as that of other networks in the vicinity. See if correct drivers have been installed. Check configuration settings for encryption keys.

As a work-around, you can connect the wire that runs from the wireless antenna port to the primary port on the cord as follows:

you say it suddenly stopped working, if you can connect to the router via ethernet cable then try to access the router's web utility page and make sure your router is in mixed or G-only. If you can't still connect to the router through wireless then try restarting the Wireless Zero Configuration from windows. This is how it's made: Go to control panel and double-click "administrative tools", then double-click "services". You will see a list, scroll down to Wireless Zero Configuration and click "stop", you'll see a progress bar. After that click "start", you'll see another progress bar. Now try connecting to your router via wireless connection. If you still can't connect then repair the connection by right-clicking the wireless icon at the bottom right corner. Keep repairing until you connect.
Hope this works!
To determine if your PC will simply not connect or if really your wireless AP/Router, please download NetStumbler,
install and run. The software will determine if there is an AP within
your immediate area (including yours/high signal strength), if there is
& it is yours, then it is configuration problem, it none or some
but weak (low signal/not yours) then it is a hardware problem and would
most probably require replacement. Most of the time, the cost/time of
repair would make the purchase of a new one more reasonable. If your
Wireless Ap/Router was detected by NetStumbler, then perhaps what you
need is to re-configure your system/set-up again.
Hope this be of some help/idea. Pls post back how things turned out or should you need additional; information.
Same problem here - wireless light starts blinking and I get a network interruption. At that point, I have to walk across the house and downstairs to cycle the power on the router to get it working again. What a pain - and the manual doesn't even mention a blinking status for that light. I'm thinking about hooking the router up to a automated power switch (X12) so I can remotely cycle the power.
