Bluetooth really bad signal, wi-fi does not work

I changed the housing of my nokia n81 and doing this I think that I only damaged the speakers, because they have bad sound, but it's not a problem. main problem is that when I connect stereo headphones via bluetooth, it has really bad signal, about 10 inches, not more. and also, it does not show me any wi-fi connection and its impossible to connect via wi-fi anywhere.

Why does my moto G from US Cellular get poor signal now that I switch my plan from the $50 plan to the $60 plan



Cellular Signal Boosters / Repeaters

Your cellular carrier can provide you with a "signal booster" device that can repeat and boost a cellular signal you already get in your house. For example, if you consistently have one bar of coverage but no more at home, a booster can take that one bar and turn it into more bars. If you have one or two bars of coverage near a window but no coverage elsewhere in your home, a booster near that window can capture the signal and boost it, providing a strong signal throughout the rest of your home.
Some carriers offer such devices very inexpensively - $50 or maybe even free - especially if you're in an area where they know they know they have poor coverage. T-Mobile now offers such boosters for only a $25 deposit, which you can get back just by returning the booster to them.
Contact your carrier - or look at their website - to see just what they'll offer you and for how much.



Femtocells / Microcells

A femtocell - or "microcell" - is a small, low-power cellular base station that connects to the cellular network via your broadband Internet connection. Essentially, it's a small cellular signal tower that will provide a signal in and near your home, connecting to the larger mobile network over your Internet connection. This makes it ideal for situations where you don't even have a signal bar of coverage you can boost at home. The only "catch" is that your Internet connection must have a high enough download speed. Different carriers require different minimum speeds, but you should be fine as long as you have a solid broadband connection.
Ask your cellular carrier if they offer this sort of product and find out how much it will cost you. As with boosters and repeaters, a femtocell may be available at a steep discount from your carrier in areas they know they have poor cellular service.
You can also buy them easily on Amazon or almost any decent tech store - for instance the one pictured below works for AT&T and supports LTE (though it is a bit pricey), or you can get one that supports Verizon, T-Mobile, AT&T, Sprint, Cricket, and many others, but you won't get LTE support. Of course, since you likely have Wi-Fi in your house, LTE isn't really a big deal and the 3G will work just fine for calls and texts.
Editor's Note: For the official How-To Geek office we got a Samsung microcell device directly through Verizon, which wasn't cheap, and doesn't work all that well. And since it only works for Verizon, any of the people who come by who use other carriers have zero signal, which is really annoying. If we could do it over again, we'd have started with this zBoost microcell that supports virtually every cell provider and has many different models and options to choose from depending on the size of the house. They even have an optional antenna you can install on your roof to give cell coverage everywhere around your house. It's the best choice, and cheaper than most carriers will offer you.



Wi-Fi Calling and SMS


Wi-Fi calling is a feature you might remember from some years ago, but it's coming back with a vengeance. At the moment, in the US, only T-Mobile offers Wi-Fi calling for both Android phones and the iPhone. Sprint only offers Wi-Fi calling for select Android phones. AT&T and Verizon have announced plans to activate Wi-Fi calling in 2015.
Essentially, WI-Fi calling allows your smartphone to receive and place calls and communicate via text messages over a Wi-Fi network. Your home probably has Wi-Fi, so Wi-FI calling will let you use your existing wireless router instead of needing a new, specialized device. You can just improve your Wi-Fi signal strength, and all your devices will benefit!
Wi-Fi calling works transparently. When your phone is on Wi-Fi and has a poor cellular signal, it will connect to the Wi-Fi network and your phone calls and text will be sent and arrive over the Wi-Fi network. When you leave the Wi-Fi network, your phones and calls will be sent over the cellular network as usual. This is all designed to hand-off automatically, so you could start a phone call on your Wi-Fi network and your phone would automatically hand off to the cellular network as you walk out the door, with no interruptions.



WI-FI calling will also work on other WI-Fi networks, so it's helpful if you ever end up in another place where you have a poor cellular signal but have Wi-Fi. To use this, you'll need to ensure your phone has Wi-Fi calling support and that it's enabled. Android phones from T-Mobile and Sprint will often include this feature, so look up how to enable it on your specific model of Android phone.
The iPhone 6 has built-in Wi-Fi calling, although it currently only functions on T-Mobile. AT&T and Verizon plan to support it in 2015. To enable this feature on an iPhone, open the Settings screen, tap Phone, tap Wi-Fi Calling, and activate it.

WI-Fi calling seems to be the future goal the industry - T-Mobile, especially - is pushing towards. With Wi-Fi calling integrated into your phone, you don't need to buy a specialized device. Your home Wi-Fi router works. And, when you go somewhere else where you have a poor signal, all they need is a Wi-Fi network and you'll be able to get a phone calls and SMS messages through it.

Analogue video senders used to send audio and video to other TVs in the home. 3. Microwave ovens emit interference in the 2.4GHz band. 4. Wireless speakers and console controllers can cause interference with the wireless router. 5. Bluetooth devices, newer Bluetooth devices can jump to different frequencies if there is a connection problem. 6. Power cables located near the wireless router can cause dropouts and speed reduction. 7. Fish tanks will cause massive Wi-Fi shadow on the other side of the tank from the wireless router. 8. Depending upon the location of large mirrors will reflect wireless signal away your computer. 9. Building materials will block wireless signals such as plasterboards with metal foil, reinforced concrete walls and floors. Also objects near the wireless router such as metal filing cabinets and other electrical appliances. 10. Blinking Christmas lights can reduce Wi-Fi performance by 25% when it is close to the wireless router.

Sees Wi-Fi but not network intermittently


Seems typical of interference. Have you checked neighbours channels. Lots of apps can search nearby channels. This enables you via the router configuration a free channel. Your signal can say strong but that means nothing. Is your router near a speaker or source of magnet / power. That can cause issues. Any chance you can move the router somewhere else. If this doesn't work then check your phone connection. Splitter change? All wires looking good. Finally you may have a faulty router. It really looks like channel garbage from others as the refusal to sync means the radio channel is damaged.

What is wifi


Hi,
Wireless local area network is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet, uses ethernet protocol.

In simple word allow you to surf internet without any internet cable connection, Wi-Fi enabled device such as a personal computer, video game console, smartphone or digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more (interconnected) access points called hotspots, can comprise an area as small as a few rooms or as large as many square miles. Coverage in the larger area may depend on a group of access points with overlapping coverage.

In addition to private use in homes and offices, Wi-Fi can provide public access at Wi-Fi hotspots provided either free-of-charge or to subscribers to various commercial services. Organizations and businesses - such as those running airports, hotels and restaurants - often provide free-use hotspots to attract or assist clients. Enthusiasts or authorities who wish to provide services or even to promote business in selected areas sometimes provide free Wi-Fi access.

Bluetooth connection to desktop?


No, PC internet connection is not shared with N800.
The only way to connect to the internet without a wifi signal is to pair your N800 with your cellphone (if it's GPRS and bluetooth capable) and share the GPRS connection.
You can do it with the connection manager of your N800
