Sony vaio loses wifi handshake


CONTINUAL DISCONNECTION OF WIRELESS CONNECTION
There are a few things that can cause you to lose wireless connection with your wireless router. 1. Weak signal strength, check the signal strength on your wireless card. If it is weak move the wireless router away from brick or concrete walls and if possible locate the wireless router higher up. 2. Have you secured your wireless router from people near your from unauthorized access? i.e. change the default password, setup encryption use WPA2 or WPA, change the default SSID, and turn off SSID broadcast, and for added protection, enable MAC address filtering which allows only the MAC address/es of your wireless card/s to connect to your wireless router. 3. You could be getting interference from electrical sources such as air conditioners, arc welders, washing machines etc. If so, the power supply to the wireless routers and computers etc should be connected to a surge protection power board, better still connect your computer equipment to an UPS (Uninterrupted Power Supply). 4. Check the channels of the wireless routers and access points in your area and change the broadcast channel on your wireless router to an unused channel or one that is currently used but has the weakest signal strength. This will minimize interference with your wireless router from other wireless routers and access points in your area.

Poor signal with WiFi on my zeepad


Having a wireless Internet signal in your home allows multiple devices to use the same Internet connection without having to run lengths of Ethernet cable to each device. Given that the wireless network is transmitted over the air, the consistency of your Internet connection depends on the strength of the wireless signal. If wireless signal strength is not strong enough to give you a consistent Internet connection, there are a few simple steps for finding the problem and improving your signal strength.

Reset all devices. The majority of Internet issues, including poor wireless signal strength, are very often solved by a simple power cycle of all the devices in the network. Locate the power cords of both your modem and your wireless router and remove them (if you use a modem/router combination, simply unplug the power to that device). Leave them unplugged for a full 30 seconds, plug them back in and restart your computer. When your computer fully reboots, check your wireless signal strength to see if it has improved. If it has not, further troubleshooting is required. Move your computer closer to your router, or your router closer to your computer. Wireless routers do not have unlimited range. One reason your computer may be getting a weak signal strength from your wireless network could be because your computer is simply outside of the router's range. Typically, ISPs (Internet Service Providers) will install your modem in one specific location in the house and the modem will not work at other locations, so moving the modem or modem/router combination may not be a possibility. If this is the case, you may need to move the computer to a location that is within the range of the wireless router's broadcast. If you still get poor signal strength, your router may be experiencing a malfunction. Contact the technical support department of your router manufacturer. Router malfunctions often are not the result of a bad or broken router, but of something much simpler, such as the router's needing a firmware upgrade or an incorrect setting on the router's internal setup. If your router manufacturer is unable to improve your wireless signal strength, it may be time to purchase a new router. Purchase a new router. Wireless routers are priced in part based on how widely their wireless signal broadcasts (in other words, the more expensive the router you buy, the larger a wireless signal the router will broadcast). Included in the packaging of each wireless router is the approximated range, in square footage, of that router's wireless network. A good rule of thumb is to know the square footage of your house and buy a router that can accommodate that square footage. That way, as long as the router is functioning properly, you will have strong wireless signal strength throughout your entire home. Hope this helps.

How do i increase wi-fi signal strength


There are only a few ways to increase signal strength ..move closer to the source (the router) , get a bigger antenna or boost the signal...you can boost the signal with foil in the shape of a parabola around the router antenna or make one out of a vegatable strainer that will plug into the laptop(this one works best )especially for picking up your neighbors WIFI

Not receiving n-type signal from router


Put the laptop next to the router and see what signal you then get. do the following
---- start>control panel>system and maintenance>system>device manager on lefthandside> network adapters click on the +sign>right click on the wifi adapter>properties>now in there there maybe a TAB for advanced which allows you to select the type of signal the adapter is set for - check its not set to G. ----- loss of signal in room, wifi signals can be reduced, if they pass through walls etc - sometimes just a small change in the routers position or aerial alignment can make a big difference ------ download and install - http://www.xirrus.com/library/wifitools.php - you can then monitor on the graph the signal strength and see when it drops off -------- also a change in the wireless channel used on the router can helpp - Use channel 1 or 6 or 11 as they do not overlap - have a look at the other signals being broadcast and what channel they are on - then choose one that is free or also on a very weak signal to minimise interference

Belkin Router Signal Weak


Wireless configurations are tempermental over larger distances. Some routers do have the ability to increase the signal strength to over come this, but a good location is key.

The more obsticals in the way the slower the connection will become. Closed doors, being buried under books, underneath desks, can all cause the signal to come through a slower speeds to compensate.

Make sure your router is in an elevated location to help with a less blocked signal.

Are you using a Wireless-N adapter on your computer? If not, you might need an extender because Wireless-G does not have the same range as -N.

With the model number of your Belkin router I might be able to assist more.

I recently purchased a Hawking HSB2 Signal Booster. Two years ago, my son installed a Toshiba Cable modem(PCX2200)and a Belkin Wireless Router(model#F5D7230-4)for Camcast High Speed Internet. The Router...


Booster will only work along with access points in your case the belkin wireless router - you have to connect the device to the router not to the windows xp pc

if you know how to configure and the device are compatiable to each other and allows bridging or can configure as your access point client then you need not wanna to get it connected via wire or T568b standard ethernet cable otherwise you have to connect with this cable will enchance the wireless activity

Wireless signals can go down its strength by any magnetic activity, oscillations such as microwave, powerful steel/metal frames and check your anteena position keep in different direction and check your pc wifi signal strength.

Interlink between your router and booster with utp cables gives you steady flow of data and full band strength.

Aviod using two company devices change the router to Hawking
Thanks Hothawk

HI,
As you have changed the router still the connection speed is slow, in this case it's better to contact your ISP get the line tested or a proper signal strength.
Also conduct a speedtest by going to the website internetfrog.com....indications are towards a line fault.
