Have you ever had problems with the WiFi signal that reaches your device? Surely it has always happened to all of us although we pay a certain speed, this does not translate into our experience when surfing the internet. No doubt this is a very troublesome situation that does not occur in isolation for a single day. We can see this for a long time and without any change.
We almost always blame the internet provider. However, there is also the possibility that we are doing something wrong, especially with the router. This is something normal, because normally they are details that seem obvious but that we usually overlook.
7 useful tips to improve the functioning of your Wifi network
- Obviously we must take into account the place where the router is installed and the point where we want the signal to be more stable (logically where we will be with our device most of the time). Applications like Wifi Analyzer allow us to know the intensity with which the signal reaches the position where our smartphone is. This app also makes a comparison with other nearby signals.
- Make sure that the router is in the most central room of the entire house. In addition, we must ensure that there are no major interferences such as walls or ceilings between this and our device (smartphone, TV, PC, etc). Any obstacle can interfere with the performance of the signal.
- Complementing the above, you should put the router at a high point and not on the ground. Do not put objects on it or put it in cabinets or similar containers. Avoid putting it next to appliances that interfere with your signal such as cordless phones, microwaves, security alarms, etc. Additionally, it must be far from mirrors, windows, fish tanks, metals, etc.
- It never hurts to mention that too many connected equipment will reduce the speed in each one of them. It is advisable to change the network password frequently and that this is not too easy. If you believe that your neighbor is connecting to your network without your permission, you can quickly change the password by logging in to your router.
- To extend the coverage of the signal, you can buy a Wifi repeater. Small versions that connect directly to the electric network are available from $ 20 and up on the Internet. On the other hand, you can also buy a router that is configured as a repeater. Both can be achieved with characteristic of “Wallbreaker”, which resists a bit the signal weakening caused by obstacles.
- Streaming services such as Netflix or playing online games require good bandwidth. If this is combined with other internet uses at the time, very poor performance will be obtained. The ideal in these cases is not to depend on the Wifi signal and connect the device by cable.
- If you are still having problems with the signal, you can check with the internet provider. Of course, before you should do a speed test to know if the network does not offer what the plan dictates. To do this, you must close other applications that use the internet and be connected by local network.
Facebook is being accused of asking big banks for financial information
Stories of this kind with Facebook already seem like a commonplace. The gigantic amount of information stored by the company and the use of the data its becoming more and more suspicious among users. This time, questions have been raised about alleged agreements with banks.
After the scandal of Cambridge Analytica and the movements against the company like #DeleteFacebook, a controversy is being generated again by the decision of Facebook to be linked with financial or banking entities. Why? The company would have asked for customer information.
According to a report by The Wall Street Journal, Facebook about a year ago was in talks with entities such as JPMorgan Chase, Wells Fargo & Co, Citigroup Inc and US Bancorp to provide a customer support service.
For this, the company would have asked the banks to share detailed financial information about their customers, including card transactions and current account balances, to “enhance” the virtual assistance provided by Messenger.
This generated alert in several users. Facebook said in the same report that “we are not using this information beyond that to enable these experiences (customer service).”
Also, in another report of the BBC, the company mentioned that “the data that the company agreed to for such purposes were not used for advertising” and that “users can always choose to link the Messenger application to their bank accounts. “
Report: Illinois could be next state to allow freight trucks to utilize emerging technology
A new report suggests Illinois could join other states in allowing freight trucks to use adaptive cruise control technology to control fuel costs and lower consumer prices.
It’s not self-driving, it’s platooning. In short, wireless technology allows multiple freight trucks to communicate to close the gap between connected lead and follow vehicles.
“Something like adaptive cruise control, a common driver assistance system,” Competitive Enterprise Institute Senior Fellow Marc Scribner said. “This is basically connected, adaptive cruise control.”
Freight trucks equipped with the technology would be able to close the gap to as low as 30 feet, reducing air pockets and providing reduction of aerodynamic drag. The estimated fuel savings could be around 7 percent for all the platooning trucks combined, Scribner said.
“There just are not many ways for a trucker to reduce costs,” Scribner said. “This could end up being make or break for some runs and that seven percent average fuel savings means that not only are trucking companies going to be spending less to deliver the same number of goods, that’s going to translate into savings for consumer goods that get moved by these trucks.”
Scribner’s report shows with the exception of Missouri and Iowa, Illinois is mostly surrounded by states that allow it and Illinois’ acceptance would foster greater and safer freight activity.
“What I propose is that [state lawmakers] add an exemption [to the following too closely laws], a simple sentence, and that would allow these trucks on the road,” Scribner said.
Illinois House Bill 4654 would allow the technology to be used in Illinois, but it stalled in committee. The sponsor of the measure, state Rep. Marcus Evans, D-Chicago, did not return messages seeking comment.
Illinois Trucking Association Executive Director Matt Hart said they support the bill.
“The technology works in limited circumstances like on rural interstates where they might want to be platooned,” Hart said. “The bill requires a [Commercial Driver’s License] holder is aboard at all times. We in no way shape or form want this for autonomous vehicles.”
Scribner said technology allowing trucks to automatically close the gap could begin implementation in states that allow it as late as 2018. What if Illinois doesn’t?
“I could imagine that you would see national trucking carriers to start looking to re-rationalizing their routing across more states where they have made this change,” Scribner said.
Hart said that’s likely not the case.
“They would have to go out of your way to avoid Illinois,” Hart said. “I hope it doesn’t come to that. We want the safest roads out there.”
But Josh Witkowski with motorcyclist lobby ABATE of Illinois has concerns.
“When you have three of these semis running together, it represents a three, to four hundred foot wall that takes away space for a motorcyclist to possibly take evasive action if something dangerous occurs in their lane,” Witkowski said.
He says the technology hasn’t proved itself like drivers have to prove they can handle vehicles before getting a driver’s’ license.
“Illinois should investigate the technology,” Witkowski said. “Illinois should test the technology in a closed environment where my life does not become the field test for these companies to push this on us.”
“We just have to find the right regulatory environment,” Hart said. “Safety is the top priority. We think this can improve safety in the long term.”

Liquid water lake found on the Red Planet
“This is an amazing result that suggests that water on Mars is not a temporary stream, as revealed in previous discoveries, but a body of persistent water that creates the conditions for life over long periods of time,” said Alan Duffy, Associate Professor at the University of Swinburne in Australia, who did not participate in the study.
Mars is now cold, arid and desert, but it used to be warm and humid and it harbored a lot of liquid water and lakes at least 3,600 million years ago.
Scientists are eager to find current water signs because such discoveries are key to uncovering the mystery of whether life existed on Mars in its ancient past or whether it could persist today.
Having the possibility of accessing water sources could also help humans to survive in a future manned mission to this neighboring planet of Earth.
The water of this particular lake, however, would not be drinkable and is located about 1.5 kilometers deep from the icy surface in a hostile and frigid environment.
If microbial life forms are there, it is a matter of debate.
Some experts are skeptical about that possibility because the lake is cold and brackish, and contains a heavy dose of dissolved Martian salts and minerals.
The temperature is probably lower than the freezing point of pure water, but it can remain liquid due to the presence of magnesium, calcium, and sodium.
“This is a discovery of extraordinary importance, and will increase speculation about the presence of living organisms on the red planet,” said Fred Watson of the Australian Astronomical Observatory.
“However, caution should be exercised, since the concentration of salts needed to maintain the liquid water could be fatal to any microbial life similar to that on Earth,” added Watson, who was not involved in the research.
The discovery was made using radar instruments from the Mars Express probe of the European Space Agency (AEA), launched in 2003.
The tool is called Advanced Radar for the Research of the Ionosphere and the Subsurface of Mars (MARSIS) and was designed to find groundwater by sending radar pulses that penetrate the surface and ice layers.
MARSIS “measures how radio waves propagate and how they are reflected back on the ship,” the study said. These reflections “provide scientists with information about what lies beneath the surface”.
The lead author, Roberto Orosei, of the National Institute of Astrophysics in Bologna, Italy, probed a region called Planum Australe, located in the south of the icy layer of Mars, from May 2012 to December 2015.
A total of 29 series of radar samplings showed a “very abrupt change in their associated radar signal”, allowing scientists to map the contours of the lake.
“The radar profile of this area is similar to that of the liquid water lakes that lie beneath the ice sheets of Antarctica and Greenland on Earth, suggesting that there is a subglacial lake at this location on Mars.” noted the report.
“This is the first water body that has been detected, so it’s very exciting,” David Stillman, a researcher at the Department of Space Studies at the Southwest Research Institute in Texas, told AFP in an email.
However, Stillman, who also did not participate in the research, said it is necessary for another probe or instruments to confirm the finding.
The scientist pointed out that a radar instrument of greater frequency manufactured by the Italian space agency, SHARAD, aboard the Mars Reconnaissance probe launched in 2005 has not been able to detect groundwater.
“It’s strange that SHARAD cannot confirm this discovery. In fact, SHARAD cannot go through the ice here and nobody understands why “added Stillman. “This suggests that something strange is happening here. Therefore, I am skeptical about this discovery. ”
But researchers are excited about the potential for future findings because if liquid water can be found at the south pole of Mars it could also be found elsewhere.
“There is nothing special about this location other than the MARSIS radar of the Mars Express probe that is more sensitive to that region, which means that there are probably similar water deposits under the ground on all of Mars,” said Duffy.
