How do I improve a routour range and speed and it has no attena?

Q. It's a at&t model 2wire

A. Try placing the router in a higher central location, avoid physical obstructions whenever possible, also avoid reflective surfaces whenever possible. Some Wi-Fi signals literally bounce off of windows, mirrors, metal file cabinets and stainless steel countertops, lessening both network range and performance.

Install the router at least 3 feet away from other home appliances such microwave ovens, cordless telephones, baby monitors, and home automation equipment like X-10 devices.

Likewise, install the unit away from other electrical equipment that also generates interference, such as electric fans, motors, and flourescent lighting.


Is there anyway to boost my reception in my basement?
Q. I get decent signal on the main floor and when i go in the basement my signal sucks. I have Verizon

A. Well here is some information that tells you what interferes with wireless signal:

Sources of interference for wireless devices and networks

The farther away the interference source, the less likely it is to cause an issue. The following items can cause interference with wireless communication:

* Microwave ovens: Placing your computer, Bluetooth wireless device, or AirPort base station near a microwave oven that is in use may cause interference.
* Direct Satellite Service (DSS) RF leakage: The coax cable that comes with certain types of satellite dishes may cause interference. Obtain newer cables if you suspect RF leakage.
* Certain electrical devices such as power lines, electrical railroad tracks, and power stations.
* 2.4 GHz or 5 GHz phones: A cordless telephone that operates in this range may cause interference with wireless devices or networks when used.
* Metal objects: If possible, move metal objects or change the placement of the computer, wireless device or wireless access point so the path between your computer and the wireless device or wireless access point is free from metal objects that may cause interference.
* Video senders (transmitters/receivers) that operate in the 2.4 GHz or 5 GHz bandwidth.
* Wireless speakers that operate in the 2.4 GHz or 5 GHz bandwidth.
* Certain external monitors and LCD displays: Certain displays may emit harmonic interference, especially in the 2.4GHz bandwidth between channels 11 and 14. This interference may be at its worst if you have a portable computer with the lid closed and an external monitor connected to it. Try changing your access point to use 5 Ghz or a lower 2.4 GHz channel.
* Any other "wireless" devices that operate in the 2.4 GHz or 5 GHz bandwidth (microwaves, cameras, baby monitors, and so on).

Note: Some devices may not overtly state that they operate in the 2.4 GHz or 5 GHz bandwidth. The operations manual should indicate the frequencies the device uses to operate. These may be referred to as "Dual Band" or "Wireless" devices.

Effect of home and office elements on wireless communication
Where you are located and what materials you are surrounded by can affect your wireless networking performance or Bluetooth wireless device. The table below shows common elements and their potential for interference.
Type of Barrier Interference Potential
Wood Low Interference
Plaster Low Interference
Synthetic material Low Interference
Glass Low Interference
Water Medium Interference
Bricks Medium Interference
Marble Medium Interference
Paper rolls High Interference
Concrete High Interference
Bulletproof glass High Interference
Metal Very high Interference

I would say your problem is Concrete because of the bricks, which are almost the hardest next to metal and bulletproof glass... But if you can get a wireless access point and get it at the entrance of the basement, it will take the signal from your router and extend it into your basement. You can take these WAPoints and move them around to see where you get the best signal in your basement with where the access point extends the signal too. I hope this helps. Also some of the other items listed above can cause inteference but I would suspect the concrete and start there. There not too expensive and you can have more than one.


Does a low signal strength make my connection worse in Modern Warfare 3 on PS3?
Q. I meant low signal strength from my router.

A. Yes. The lower the strength of the signal, the slower it will be.

To increase signal strength, you need to remove sources of EMI (electromagnetic interference) such as baby monitors, 2.4GHz phones, microwaves as well as possibly moving the router to a better spot to decrease dead zones in your coverage area. You can try moving the router closer to the PS3 if that's an option.

Other options include installing a bigger antenna, a directional antenna or adding a wireless access point.

And another way is to eliminate WiFi completely by using Powerline technology. You can use the electrical wires of your house to transmit data. You would need an adapter on each end, though.


My wifi is very slow at night, fast in morning?
Q. Recently my wifi started crawling at night, while connected speeds were normal, or above expected. Speedtest,net results used to top out at 9mbps, now connected is ~13, but wifi is ~1. Actually wifi starts at 2-3 mbps during the test but drops to around 1mbps by the end of the test.

I can try wifi in the morning and the speed is back to 13-14mbps.

I've reset the router, changed network names, but wifi is still slow in evenings while connected speeds are super fast.

This is a Cisco E1000 router. I disabled QOS which might prioritize certain items. The router shows only 2 connections, both of wich are mine.

Any help would be greatly appreciated.
Thanks for your responses so far. I will add that the network is password protected and i have confirmed via the router that there are only 2 connections, my desktop and iPad.

A. Assuming your wireless network is secured and you don't have leaches sucking up your bandwidth then I would suspect wireless interference.

By nature, interference in wireless systems causes problems with smooth, consistent speeds.

Many wireless connections experience interference from microwave ovens, cordless phones, baby monitors and other wireless devices which interfere with the 2.4 GHz band.

Dual band routers have multiple wireless radios enabling broadcast on the 2.4 GHz and 5 GHz bands simultaneously.

Using the 5 GHz band cuts down on interference from cordless phones and microwave ovens..

Not all devices can use the 5 GHz frequency. Many laptops and other devices only operate at 2.4 GHz. Thus the need for dual band routers.

What all this jargon means is that you might be experiencing wireless interference which is slowing do your WiFi connections.

Because your problem is time based, are there any heavy electrical loads that come on when you experience problems? Things such as heaters, air conditioners, pumps, etc.

You can try to reposition the antennas on the router or your wireless adapter.

Moving one or the other away from dense walls or electrical interference would also help.

Wireless connections are never as fast or consistent as wired connections. If your interference is on the 2.4 GHz band and your devices support 5 GHz then a new dual band router might help.

There are also various ways to extend a Internet connection to areas with a weak wireless signal.

Devices such as wireless extenders can expand your wireless range if need be. http://www.amazon.com/gp/product/B004YAYM06/ref=as_li_ss_tl?ie=UTF8&tag=excharge-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B004YAYM06

The wireless range extender receives weak wireless signals and repeats them to extend the signal range to greater distances. Some models include 4 Ethernet ports in addition to the wireless radio.

The best solution would be to use a wired (Ethernet) connection between your devices and the router.

If it is not feasible to run cables you have other options such as powerline network adapters You plug one in by the router and one in the room where you need access and connect them to the devices with standard Ethernet patch cables. http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/

The network signals are transmitted over your existing home electrical wiring which will not be affected by wireless interference.

Good Luck...
