baby monitor that works with android image
hosj
so I had to factory reset my computer after a blue screen issue and connecting to the internet is more of a battle then anything. before I had to reset it my wifi was pretty good now playing games like wot or wow are very slow and laggy but from time to time for about 5 mins it will work great. my android tablet works great doing all sorts of things fromt the exact same location as the laptop. specs: hp 2000 , 4gb ram, dual core procceser, NVidia card , and a telus router. wifi was working great before reset but not anymore another reset would be very unconvienent and I never have any background applications running I have high performance option on. please help
Answer
Best guess would be drivers for the WiFi interface. Try updating the drivers.
That being said,
Although WiFi connections are convenient for mobility and ease of installation, wireless interference can cause it's connection speed and quality to vary wildly.
Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.
All of these factors will affect your actual wireless range. As wireless connection quality varies, the connection speeds are renegotiated. The WiFi connection between your device and the wireless router may start at 300 Mbps and end up at less than 10 Mbps or drop entirely.
The WLAN connection speed is only between the device and the router, you are still limited by your WAN Internet speed provided by your ISP.
Often signal strength (bars) displayed by your device can be misleading, WiFi interference can cause havoc with consistent speed
Even more important than download speed for online gaming applications is the increased latency experienced by a wireless connection.
Latency is the delay (ping time) in milliseconds that it takes the signal to travel to the server and back. The lower the number the better, but you'll definitely want a ping time of under 120 ms or you'll have major problems. Ideally you want less than 80 ms ping to the gaming server.
Your latency (ping) may be 30 ms and wireless interference could cause it to spike to 300 ms or more. In short, wireless connections suck for online gaming.
For serious gaming or video streaming your best bet is a direct Ethernet connection. Ethernet is unaffected by wireless interference and will give you a rock solid, stable network connection.
Try a speed test http://speedtest.net from a laptop or PC directly connected to the router via a Ethernet cable to see how much speed and latency you are giving up for the convenience of a wireless connection.
If it is not feasible to run Ethernet cable the next best option would be a set of powerline network adapters http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/
You plug one in by your router and one in the room where you need access and connect them to the devices with standard Ethernet patch cables. The network signals are transmitted over your existing home electrical wiring which will not be affected by wireless interference. There is still some extra overhead in the connection but it is much more stable than WiFi.
For stationary devices I always recommend Ethernet connections, however I realize that this is impractical for devices such as tablets, iPods, cell phones, etc.
You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.
You could also try adjusting the position of the router or relocating your device closer to the wireless router to obtain a stronger signal.
If you still have a weak wireless signal you can get a wireless range extender or a wireless adapter with better range for your WiFi device.
Wireless adapters come in many types and sizes, you may want a high power USB model with external antennas. http://www.amazon.com/s/?_encoding=UTF8&camp=1789&creative=390957&keywords=high%20power%20wireless%20adapter&linkCode=ur2&qid=1374458138&rh=n%3A13983791%2Ck%3Ahigh%20power%20wireless%20adapter%2Cp_72%3A2661618011&rnid=2941120011&tag=excharge-20
The wireless range extender receives weak wireless signals and repeats or regenerates them to extend the signal range to greater distances.
Here are the two most popular highly rated models on Amazon.

Built new desktop, need wireless?
Tigger
Hi guys. I built a new desktop, and now I need internet. I can't use wired connection for reasons. Right now I'm using a TEW-645UB Trendnet adapter. It works but it only picks up a few bars, and it's laggy in game. I'm using my desktop for gaming.
Is there a better adapter out there?
Answer
That Trednet model is a decent High Power Wireless N Adapter with full backwards support for IEEE 802.11b/g, and support for latest IEEE 802.11n Draft standard. It is likely that the position of the router is causing thee problem.
I would certainly try and improve things by repositioning the router [I have suggested several things below] before rushing out to buy a new adapter that may or may not improve your signal.
It would obviously have helped if you had given details on the make and model of the router and whether it supports draft n wifi standard and if it has "Dual Band" support for broadcasting simultaneously on both 2.4GHz and 5GHz frequency bands.
There are several things you can do do try and boost signal strength; To start with the basic rule is to position the router as high as possible and there are as few walls as possible between it and the PC.
Things you can do to improve signal strength
1] Try changing the broadcast channel from the wireless setup interface for your router/modem.You can normally access this by typing "http://192.168.0.1/" into your browsers search bar and then look for the wireless settings menu.
You don't say if your router can use the 5GHz frequency or just the 2.4GHz. The best channels in the 2.5GHz spectrum are 1,6, 11, or 13 as they have less overlap with the other channels.
There is a useful article here about how to get the best performance by selecting the best channel.: http://www.howtogeek.com/howto/21132/chaâ¦
If you have an android smarthphone, or a friend does, then install the Wifi Analyzer app free from android market and use it to scan for the best channel and change your routers broadcast channel accordingly. This app will also show you all the wifi signals in range that your neighbours are using, so you can select a different channel to them, making a stronger signal for you. https://market.android.com/details?id=coâ¦
2] You can use a tool like Nirsofts totally free WirelessNet View to look at all the local wireless signals that are within range and may be competing with your own router and interfering with reception. from here: http://www.nirsoft.net/utils/wireless_neâ¦
3] You can buy a Wi-Fi booster like D-Link 645 Smartbeam, here: http://www.amazon.co.uk/D-Link-DIR-645-Wâ¦
Devices such as these can actually boost the wifi signal by using multiple beams that bounce of the walls and are intelligently directed toward whatever device [smarhphone, laptop, tablet] you are using on wifi.
4] If your using the 2.4GHz frequency and not the 5GHz then other devices that use this frequency band can also interfere with your reception [eg baby monitors and microwave ovens use 2.4GHz]. Try and make sure that none of these devices are situated between your router and your PC
