How to Upgrade Wi-Fi on your Laptop

Everyone knows that cheap laptops come with inexpensive Wi-Fi modules. Manufacturers need to use cheap components if they want to release a best seller, and skimping on Wi-Fi is ideal, because the effect isn’t immediately visible.

A cheap display or a wobbly keyboard are much harder to hide, so the “clever” laptop makers tend to keep the weak components hidden inside the laptop’s case. On the other hand, a fast CPU and a big hard drive are features that will easily attract buyers, especially if the price is low.

Some of the cheapest modules are soldered onto the motherboard, and this makes them extremely hard to replace. However, Wi-Fi modules are usually replaceable, and by doing this you will easily double the speed of your Internet connection for only 20…30 bucks.

Ultrabooks are great portables, there’s no doubt about it! Still, if your laptop falls into that category, it may mean that you are out of luck. Half inch thick laptops rarely have standalone Wi-Fi modules, even though it may happen from time to time. But don’t lose hope, we’ve got some solutions for you as well.

Let us assume that you have a standard laptop, and not an ultrabook. Begin your journey by downloading your laptop manual, in case that you don’t have it. Websites like these are of great help:

Often times, your will discover several screws that allow you to open compartments which provide access to the memory slots, hard drive, Wi-Fi module, etc. Locate the Wi-Fi module, and then its antennas; regular modules have one or two antennas, even though you may find a Wi-Fi module with three antennas every now and then.

Disconnect the antennas, and then go shopping for a compatible Wi-Fi module. Insert the module into its socket, and then reconnect the antennas. If all goes well, you’ve just upgraded your wireless Internet connection. Not only that, but by replacing the Wi-Fi module you may also get access to new features like faster Bluetooth connections, access to Intel’s WiDi technology, which allows your laptop to connect to a TV wirelessly, and so on.

But what about the poor folks who haven’t got the option of replacing the internal Wi-Fi modules? Fear not, for there are several solutions that can fix the problem for good:

  1. Upgrade your router. Install the latest and greatest router firmware update or, if you have an old router model, get rid of it and purchase a new one. Your laptop will thank you!
  2. Use a repeater. Don’t worry, this is just a fancy name for a device that strengthens your Wi-Fi signal, picking it up and rebroadcasting it. If your laptop is placed in an area with poor Wi-Fi signal, a repeater will work wonders.
  3. Replace your router antenna. Use a good antenna and a good RP SMA cable – don’t buy cheap stuff, because you’re going to waste your money without seeing any improvements. Omnidirectional antennas are able to broadcast Wi-Fi signal in all directions.
  4. Use an external Wi-Fi adapter. Trust me, this is one of the smartest things you can do if you can’t replace the internal Wi-Fi module. Make sure to buy a good quality module (Intel’s chips are very good), plug it into an USB port, let it install the needed drivers, and voila – you have significantly upgraded your Wi-Fi.
  5. Adjust your router’s power. Did you know that many routers allow you to set their broadcasting power? Often times, their default settings are OK, but it’s well worth it to verify this setting. Boost the power and all the Internet ready devices in your home will receive a stronger Wi-Fi signal.

Armed with this info, the only thing that stands between you and a nice Wi-Fi boost is… you! Pick the best method that works for your laptop, apply it, and you will be ready to reap the true benefits that arise from having a broadband Internet connection.


Louis Kraml’s Medical Newsflash

The old depression studies led to results that made the psychologists think that women tend to get depressed much more often in comparison to men. Recent studies have shown that the depression risks are quite similar regardless if the patients are men and women. The old findings were (apparently) flawed because men kept the suffering for themselves, while women are more inclined to talk about the problems that they are experiencing.

The new study took into account factors that are connected to men behavior, like substance abuse, aggressions, and so on. Abnormal risk taking is another aspect that could signal depression in men, note the scientists.

Until recently it was believed that the risk for women to get depressed was twice as big as the risk for men.

According to the Louis Kraml News Site, the Electronic Health Record System has been successfully rolled out. The initial step of the program was supposed to target about 80-85% of the medical institutions until the end of the year, but it looks like these targets were reached several months ago. Close to half of million people are now using the electronic health record system, helping the medical personnel take proper care of the people that might not be able to remember all their medical history, as well as of those that are unable to give information.

An article in which Louis Kraml discusses Alzheimer’s Disease and Dementia brings in good news: according to a recent study, standard medication that is usually utilized to keep high blood pressure under control could stop Alzheimer’s disease and dementia from developing. Beta blockers are, according to the study, the most effective medicines to prevent the deterioration of the brain.

Additional benefits have been found, with a much lower number of micro infarcts being at the top of the list. As the population grows, the number of people suffering from dementia is supposed to grow as well. Nevertheless, the study offers hope to the human kind, providing an easy way of keeping Alzheimer’s disease under control.

How to we deal with obesity? It’s a question that was once addressed to adults, but unfortunately it applies to our kids as well. Doctors recommend that our kids should spend more hours in the gym, but this is something that is easier said than done, when you take into account the fact that the doctors and the teachers are parts of two completely independent systems.

Will this (spending more time in the gym class) make our kids get poorer grades? At this point there aren’t any studies to prove that; in fact, it may even be the other way around, because the kids’ higher energy levels may make them be more efficient with their homework.

The Institute of Medicine recommends daily sessions of at least 30 minutes of physical activity for all the children.
