  3. How To Detect Wifi Interference
Lately, I have been suffering serious drop-outs in the 2.4 GB spectrum. Speedtest.net often struggles to get above 20k! Normal speed is around 4.5mb and this is consistently achievable when I use the 5g connection so I am assuming that this is nothing to d with the ISP. I have found this happening with two high spec routers so now think I have external influences at play. I have found that the problem is better if I fix the router on Channel 1 but it is still flaky.
I live in a small spaced-out rural community and I can only see low level signals from the neighbours. I have been round the house and disconnected all the 2.4ghz devices I can think of but this problem is reminiscent of problem I had a couple of years ago when a TV sender went nuts and wiped out the spectrum.
So, can someone suggest a tool - maybe an android app, that could hel to pinpoint any erroneous 2.4ghz signals? I have the usual WiFi analyzer installed but this only looks at router signals.
Thanks

Does your wireless network seem slow? A recent study by Epitiro, a UK-based broadband-analysis firm, shows that consumers lose an average of 30 percent of the data speed their broadband connection supplies when they use Wi-Fi connections in the home.

In order to achieve optimal reliability and throughput for your WiFi( 802.11) wireless network it is necessary to detect and identify sources of interference that impact negatively on its performance. There are a multitude of electronic devices that transmit RF energy into the airspace. To minimize interference between your Wi-Fi and Bluetooth devices, try the following: Change channels on your wireless network. Connect to a 5 GHz wireless network (if possible). Move your computer and Wi-Fi router closer to each other. Minimize the number of active Bluetooth wireless devices you have connected to your computer or nearby.

Why the slowdown? You've probably heard that some household electronic devices, including microwave ovens, baby monitors, and cordless phones, hamper Wi-Fi performance. To separate fact from fiction, we did some research and consulted an expert on the topic: Nandan Kalle, networking business unit manager for router manufacturer Belkin.

1. Public Enemy Number One: Your Neighbors' Wi-Fi Networks

'I'd say the biggest source of interference today for most people is their neighbors' Wi-Fi networks,' says Kalle. The problem is that most existing Wi-Fi equipment operates on the crowded 2.4GHz band. 'There are basically three nonoverlapping channels. I always describe it as a three-lane road that's really, really busy,' Kalle adds.

If you use a 2.4GHz router and live in a densely populated area, your neighbors' Wi-Fi networks could interfere with yours, hindering the performance and range of your wireless network.

The solution: Buy a dual-band router that operates simultaneously at 2.4GHz and 5GHz. While the 2.4GHz band is necessary for supporting older Wi-Fi devices, 5GHz 'is almost like an 11-lane highway that nobody's heard about yet,' Kalle says. 'There's much less congestion.'

Newer Wi-Fi devices, including tablets such as the Apple iPad and Motorola Xoom, Internet-ready TVs with built-in Wi-Fi, gaming consoles, and business laptops, are all dual-band. 'They all play in the 5GHz band. They can take advantage of that empty highway, and that's really going to help,' Kalle says.

It's important to get a router that supports simultaneous 2.4GHz and 5GHz, such as the $100 Cisco Linksys E2500. Some older dual-band routers allow only one band at a time; that's a problem if you have older Wi-Fi devices (as most people do), because you'll have to leave your router at 2.4GHz. 'You won't get any benefit from the 5GHz mode,' says Kalle.

When you're shopping for a new router, look for a dual-band, 802.11n MIMO device, which typically has an 'N600' label. The 'N' refers to 802.11n, an international Wi-Fi standard approved in 2009. MIMO (multiple input, multiple output) technology provides greater range by using multiple antennas to transmit and receive data. And '600' refers to two bands, each transmitting at 300 megabits per second.

Is your microwave oven, cordless phone, or baby monitor sabotaging your Netflix stream? Download lagu uje bidadari surga. Perhaps.

Most problems with cordless phones and microwaves involve products that use the 2.4GHz band. Many baby monitors operate at 900MHz and won't interfere with Wi-Fi. However, some wireless monitors are 2.4GHz, which can interfere with 802.11g or single-band 802.11n routers.

How To Check Wifi Interference

The solution: When choosing a wireless baby monitor, look for a 900MHz model such as the Sony 900MHz BabyCall Nursery Monitor ($45). Alternatively, get a Wi-Fi-friendly system such as the WiFi Baby 3G ($279), which connects to your existing wireless network.

How To Detect Wifi Interference

Newer cordless phone systems like the Panasonic KX-TG6545B ($140) use DECT 6.0 technology and the 1.9GHz band, not the 2.4GHz or 5.8GHz bands.
