How to Fix Your Home Network

Many people have problems trying to set up and run their Wi-Fi networks. Maybe the router setup manual isn’t too clear. Or maybe everything worked fine in the past, but now the network refuses to cooperate, disconnecting devices or not allowing new phones, tablets or computers to connect to it.

No matter the cause, it all boils down to a few key things that could cause problems. Read this article and you will have a clear understanding of what went wrong.

  1. Router/Network Client Miscommunication

This happens when the router isn’t set up in mixed mode. If this is the case, a router which was set up to run in 802.11g mode, for example, will not support older devices, which are only able to communicate using the 802.11b protocol. Make sure that your router broadcasts in a way that keeps all the network clients happy.

  1. Router/Network Client Security Issues

Modern Wi-Fi devices support all network security protocols: WEP, WPA, WPA2. If one of your devices is so old that it doesn’t understand at least WPA, the time has come to throw it away and purchase a new one. Ideally, all your Wi-Fi devices should utilize the WPA2 protocol.

  1. Wi-Fi Security Keys Issues

If your Wi-Fi network appears to run fine on some devices, but it stopped working on others, chances are that the network password was changed a while ago, but it wasn’t updated on the devices that don’t work anymore.

If this is the case, tell the device to forget the network, rescan for it, and then connect to it using the updated password.

  1. MAC Address Restrictions Issues

Most routers support MAC address filtering. It’s a security feature that (in theory) will only allow access to the devices whose MAC addresses have been whitelisted. Sadly, hackers have come up with easy methods to clone MAC addresses, so MAC filtering won’t be of too much use when it comes to protecting your Wi-Fi network.

If a particular device can’t connect to the network, ensure that MAC address filtering is disabled, or at least that the device’s MAC address is whitelisted in the router admin panel.

  1. Bad Network Cables

Believe it or not, bad router cables are one of the most frequent causes of network downtime. And even with Wi-Fi networks, you shouldn’t forget that you’ve got at least a network cable that connects your ISP with the router.

If all your devices refuse to cooperate, it’s wise to diagnose and fix the network cable before suspecting a router hardware failure.

  1. Outdated Router Firmware/Damaged Routers

Router manufacturers push new products on the market every year, because their main goal is to make a profit. Sure, they will create new router firmware versions for a year or two, but then they will forget about their older products.

To make things even worse, many routers stop working after a few years. Power surges, lightning strikes and overheating are some of the most frequent router failure causes. If your router is placed outdoors, consider investing some money into a Wi-Fi outdoor enclosure. It’s a wise one-time investment that will help fix several problems.

It is also wise to set aside a budget and replace your router every three or four years – even if it doesn’t break! This way, you will upgrade your network to the latest Wi-Fi technologies, keeping its security to a high level.

  1. Router Overheating

If your router restarts periodically, it may overheat because it downloads or streams huge amounts of data for hours.

To verify that, unplug the router, let it cool off for 30 minutes or so, and then power it back on. If it stops restarting for a while, you may have found the problem. If this is the case, consider moving the router in a cooler area, or have a small fan blow air at it.

  1. Wi-Fi Signal Interference

Many people discover that their Wi-Fi networks simply stop working the minute they turn on a microwave oven. Others find out that the devices are unable to connect to the network while their wireless phones are active.

Wi-Fi signal limitations are real, and there aren’t too many things that can be done about that. To limit interference, try changing the Wi-Fi channel, moving the router or boosting Wi-Fi signal strength.

Over 4.5 Million Copies of TrackR Bravo Sold

Lately, I’ve seen TrackR Bravo ads pretty much everywhere. In fact, they’ve haunted me so much that I finally chose to review TrackR.

I think that its success shows clearly that many people have lost their cars in the parking lots. Fortunately, a company from California has launched this gadget, which is supposed to make the drivers’ lives easier.

TrackR Bravo is a small sized device and comes with a companion smartphone app. The gadget can be attached to the car, or to anything else you’d like to keep track of.

The device can also help people find their lost pets, keys or wallets, provided that it was previously attached to them, of course. The entire set up process takes less than 5 minutes.

TrackR is basically a small GPS that can be hidden under a floor mat, for example. This way, if somebody steals your car, you will be able to track it and find it. The device has a very impressive 1 year battery life, considering the fact that it uses a tiny battery. It has iOS and Android device support and ships everywhere in the world.


Google Removed close to Two Billion Ads in 2016

Now that’s a surprising title, isn’t it? Google makes money by displays ads, after all, and not by taking them down!

The sad reality is that some people use Google to promote all sorts of products and services that aren’t useful, don’t do anything good, or may even harm us! According to Engadget, Google has removed about 1.7 billion ads last year, an increase of about 200% in comparison with 2015.

Close to 70 million ads were advertising pharmaceutical products, another 80 million were deceiving and misleading, while over 110 million ads made use of trick-to-click techniques.

About 6,000 Google AdWords accounts were closed during the process. It’s a great start, but I’ve got a feeling that the problem hasn’t been solved for good yet.


New 5.5-inch LCD Curved Display

A new bending screen, which was produced by Japan Display Inc has been presented to the public. It is a 5.5-inch screen that can be easily bent, just like the new OLED displays which are produced by Samsung and LG. It’s not official, but this new type of screen may be used for the next generations of Apple iPhones.

Due to the smaller production costs, we will surely see more phones with curved screens this year. The main problem with the previous generations of LCD displays was the need for a glass back plate, which made curving screens almost impossible.

Japan Display has replaced glass with plastic, making it easy for its displays to bend. As an added bonus, the screen will not crack if the phone is dropped accidentally on a hard floor.
