Why is my internet so much slower on my laptop?

Q. I'm with virgin, both my computer & my laptop are connected to my via wireless connection. But my laptop gets but a small fraction of the speed my computer does.

Any ideas on how to sort this out?

A. I assume that although you say both the laptop and desktop use a wifi connection that they are not situated in the same place. It is likely that the signal strength will vary in different positions in your house. If the router supports the latest draft n wifi standards and so does the wifi adapter in your desktop then check that your laptops adapted supports 8011n too. If it only supports earlier wifi standards like 8011.g then this is much slower and the reason for the difference.

If the wifi chip in the laptop also supports the 8011n wifi standard then there are several things that can affect wifi signal and things you can do to try and improve things

To start with the basic rule is to position the router as high and as centrally as possible in your house.

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/cha�

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 aslo 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=co�


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_ne�

3] You can buy a Wi-Fi booster like D-Link 645 Smartbeam, here: http://www.amazon.co.uk/D-Link-DIR-645-W�
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 alsso 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 wifi receiver eg laptop, tablet, smarthphone etc


How old was your child when you stopped using the monitor? If you had 2 young kids, did you...?
Q. ...use 2 monitors?
We'll be having baby #2 soon. and #1 will be 2 years old. Do we buy another monitor?

A. Once the older kids were in a bed and not a crib, we stopped using a monitor for them. At that time, if they needed our attention, they could climb out of bed and come get us. And although we had to train them with the sometimes-conflicting message "OK, now you have to stay in bed, but you can get out of bed if you need us", it has worked well for three of our children so far (#4 is still in the crib).

So if you are putting your 2-year-old in a big boy/girl bed, I think you can ditch the monitor. But if the two year old is staying in a crib, I say you buy another one. Otherwise, you have no way of knowing when they are in distress. Sometimes though it is hard to operate two monitors in the same house. Despite specifically purchasing one with different frequencies, we have had trouble getting two separate monitors to work.

They do sell a monitor that we now own made by First Years that we have now that has three different base units and three different channels on the receiver. The receiver can be set to either one channel exclusively or it can cycle through all three channels. We have owned probably three different monitors over the years and this one is definitely the best.

Good luck with the new baby and your new "big brother/sister"!!


Hot to set up a sound system throughout the house?
Q. This house is already pre-wired: it has in-ceiling speakers in the master bedroom, bathroom, garage, and patio (these are 80W). Every set of speakers has its own volume control. Plus there are also 6 speaker hook ups in the living room.

I want to set up capable of playing different things at the same time, ie. if I want to hear music in my bedroom, while my roommate watches a movie in the living room. How can I do this? what good receiver can handle this? I need a receiver capable of handling 2 or more different sources at the same time.

I also need a surround sound sys for the living room. It has the cables, but not the speakers. Recomendations?

Do I need an amplifier too, or the receiver alone can deal w this?

I'm pretty new w all this, so info w baby steps will be greatly appreciated :-)

A. I have provided links below with tutorials and diagrams for multi room applications. You will need a receiver with dual zone capabilities. You do not say if your volume controls have impedance matching. If they are impedance matching controls you will only need to add a fairly beefy two channel amp (which you will connect to your receiver's zone two preamp outputs) to drive the speakers in the bedroom, bathroom, garage, and patio. If these volume controls do not do impedance matching I recommend you get a multi channel amplifier (you will need at least eight channels) which you will connect to the zone two preamp outputs. This will give you MUCH better performance in your bedroom, bathroom, garage, and patio than trying to drive all 4 pairs of speakers by your receiver's zone 2 output (low power). You do not need a speaker selector (switch) since you have volume controls unless you want to use this for impedance matching. I would not recommend it for that purpose though (signal loss). Either go with an impedance matching block or (BETTER) go with the multi channel amp. Since volume controls usually don't provide much information on the front and since you are pretty new to this you may need to find out who installed the system to find out if these controllers are impedance matching. Worst case scenario an installer can look at the back of the controllers to tell you if they are impedance matching. People who do multi-room on the cheap usually go back eventually to upgrade their system. Best to do it right to begin with.

Recommendations for your home theater:
1) Do a lot of comparison listening and pick what sounds best to you.

2) Be sure to listen to brands such as M&K (I like these alot), Monitor Audio, and B&W on the higher end. On the slightly lower end try brands such as Boston Acoustics, Klipsch, and Paradigm.

3) Recievers: I like Denon (sound quality). Onkyo, Yamaha, and Harmon Kardon are good too.


wanted to by cheap loud party speakers. any ideas where to start?
Q. want to buy some cheap but loud party speakers. will need speakers and a receiver.. no idea what brands are good or bad.. don't wanna spend alot either

A. Teac AG 790A AM/FM Receiver 100 watts at $129
http://www.sonicelectronix.com/item_20386_Teac+AG-790A.html

Dayton B652 Speakers $29.00 a pair.
http://www.youtube.com/watch?v=aBVz14hDEGI

Dayton Subwoofer 80 watts at $79
http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-631
Stick with the Dayton Sub woofer because the by pass, or how the speakers are wired match the by pass for the sub.

I would suggest a spend on a few book shelf speaker stands. Get the sub off the floor, it doesn't have any legs beneath and you should be good and loud, party clear.

This set up matches or aligns perfectly based on measured hertz. In laymens terms your music will sound right, buffed and colorful. You have more power in the receiver than needed with the speakers and 75% of the power from the receiver you have in the sub. Result, none of your pieces over power the other, and they are all being pushed to capacity to give you the best of what they can do every time you hit the power button. Not a bad deal under $250.00 for a set up.

If you want to step up M Audio Studio Monitors makes a great speaker at $99 a pair, notice the similarities to Dayton speakers for $29.00 a pair. Dayton compares favorably against the M Audio for less money. The M Audio is the better speaker, but notice the value with Dayton B652 Speakers for instance both have similar speaker architecture both can have bragging rights for crisp clear sound. The M Audio will best the Dayton in the low notes, but that is where the sub makes up the shortage. The M audio will not need a sub.
One more brand to consider is Fluance AVBP2 BiPolar Surround Sound Sattelite Speakers $99.00

I have owned my FLUANCE speakers for 4 yeras now, Why drop all that money on Bose, when Fluance is just as good if not better!!! Try them out for yourself! I have four of these surround, two towers, center channel and 10 inch sub, 7.1 surround sound for games, movies and music. You won't be dissapointed.
Ken W, Eatontown, NJ (Submitted on April 26, 2009)
I've had these speakers for well over a year now, (I have 3 of them for a 6.1 system) and they are absolutely superb! After a relatively short break in period of regular use, they will yield hours of unparalleled listening pleasure. They handle just about anything you throw at them; the imaging is clear and dynamic. They are well constructed, and the value you get for the price of these babies is off the charts. I cannot recommend these speakers highly enough. I'm waiting for them to come back in stock to I can add another one to create a full 7.1 system for use with a Blu-Ray player (most likely the Oppo BDP 83 when it's released). Look no further than these speakers if you are in the market for surround speakers...you will not regret it!
Gilles C, Sainte-Anne-Des-Plaines, Québec (Submitted on April 22, 2009)
