A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

If you suddenly encountered the PDC WATCHDOG TIMEOUT BSOD Blue Screen stop error with a bug check value of 0x0000014F, then it’s probably due to a system component that has failed to respond with the allocated period which prevents the system from exiting connected standby. This kind of Blue Screen error could be caused by both hardware and software components. To fix this Stop error, here are some possible fixes you can try that might help but before you proceed, make sure that you create a System Restore point first and boot your computer into Safe Mode with Networking.

Option 1 – Try to rollback, update or disable drivers

The next thing you can do to fix the PDC_WATCHDOG_TIMEOUT Stop error is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, look for the device driver named “IDE ATA/ATAPI controllers” and expand it.
• Then look for the SATA AHCI Controller entry and right-click on it. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.
• Next, follow the screen option to update or uninstall it.

Hello and welcome everyone, just a few years ago we had FLASH video content on the internet, we had FLASH games, full FLASH website experiences, and more, but then flash was shut down mostly due to security reasons meaning that in just a few months we have lost most of FLASH web content. However, there is still FLASH content on the internet even today, there are still FLASH videos and flash games, but we can not play any of that content since browsers do not support FLASH and you can not get the FLASH plugin for browsers. So what might be the solution for this situation?

Ruffle and FLASH emulation

Emulation of course. We will not be able to get the flash player working, well at least not the original and official one, but we can make flash content playable again inside our browsers. The first thing is first, we need to get an emulator package from the internet in order for this trick to work, one we will be using is RUFFLE. It is lightweight, it is free, it is open source and it is reliable, everything we need. Download RUFFLE from its official website here. For Chrome and Edge download the ZIP package, for Firefox, go to the Firefox section of the tutorial. There is also a desktop version of RUFFLE there so if you are keen on playing your flash content on your desktop computer you might well grab that as well, but for the sake of this tutorial where we are enabling flash in our browsers, we will not focus on that part since it is pretty straightforward. Now once you have downloaded the RUFFLE emulator, please extract it to the desired folder somewhere on your computer. Once it is extracted, start your browser of choice and follow instructions.

FOR CHROME:

1. Navigate to: chrome://extensions/
2. Turn ON developer mode in the top right corner
3. Click on Load unpacked
4. Navigate to the folder where you have extracted RUFFLE

FOR EDGE:

1. Navigate to: edge://extensions/
2. Turn ON developer mode on the bottom left corner
3. Navigate to the folder where you have extracted RUFFLE
4. Turn RUFFLE ON

FOR FIREFOX:

1. Go to the RUFFLE download page, we can not use the zip package we were using for Chrome and Edge
2. Right-click on the Firefox download link
3. Save link by clicking on Save link as...
4. Navigate to about: debugging
5. Click on this Firefox
6. Click Load Temporary Add-on
7. Select the .xpi that you have downloaded

If you have a laptop that is slowing down and some usual tasks are sluggish you probably mean that it is time to change it and get a new one. Altho it is a good solution and it will guarantee that you will be able to do your tasks with more speed and comfort, straight purchasing is not always the best thing to do.

There are things you can do and some upgrades that are cheaper and will bring your laptop back into the game and extend its usage for a few more years.

1. Clean it

The most common issue for slowing down of computer is dust and dirt that accumulates over time and usage. If the laptop has not been properly cleaned in a while, cleaning it and placing new thermal paste on the CPU can do wonders. If you are not keen on doing this yourself or do not possess the required skillset take it to your local IT center for cleaning.

2. Uninstall software that you are not using

Various software can have speeding effects on computers, it can have some services running in the background and thus take precious resources slowing the whole system. If you are not using software, uninstall it.

3. Do not install the latest software

If you are using your computer for basic tasks there is no really need to install the latest and best. A lot of new software will require new hardware and things that offer are not so much better nor even required to justify the upgrade. Let us take office, for example, if you are using it to just write some text and not using any advanced options there is really no need to switch to a newer version, the old one will do just fine tasks that you are in need of.

4. Replace HD

Now this fits in the domain of upgrading your hardware but still it is much cheaper than replacing the whole laptop. Windows 10 works much better with SSD and SSD itself is faster than your standard HD, especially if it is slower model spinning in only 5400RPM. Operation of HD replacement is simple and straightforward and anyone can do it but the benefits of replacement will be visible right away. With a new SSD instead of an old mechanical one, you will have the feeling that you actually bought a new laptop.

5. Add more RAM

This is basically the last thing you can do in order to speed up your old laptop that will not break your bank account. Upgrading RAM was always the thing that can push your computer to have more power and to behave better while you are doing tasks. One important thing here is to first see how much RAM you have in your computer. If you are packing already 8GB then upgrading will not do much but if you have only 4GB, raising it to 6GB or 8GB will be beneficial. Also, check if the model of the laptop supports more RAM in the first place.

Conclusion

We have covered here a vast array of options in order to get your laptop back into the game with variability between hardware upgrades to taking care of your software. Whatever option you choose to do it will speed up your computer but among all of them, replacing the hard drive will do the most.
