How to improve wifi signal


Hello everybody can anybody help me with this problem.
My wifi signal seems to be very weak I only get 1 or 2 bars showing
wifi strength. When I bring the laptop closer to the router
everything is all right. Any help would be great

Here are some details:

operating system: Mint 18.1 - XFCE - x86_64 Linux 4.4.0-53-generic

Driver: realtek - rtl_8723be

link quality is 49% (34/70
signal level -76 dBm (0.03 nW)

tx-power 20 dBm (100.0 mW)

The things that affect WIFI signal strength are mostly NOT in your laptop.
Some questions to consider: (No need to answer these for me, but DO answer them for yourself)
Where is your WIFI router?
Can you mount it in a more central location, away from walls, fixtures, appliances, and other things that can interfere with or eat your signals? Can you move that book off form on top of it? <joke>
If it has external antenna(s), how are aligned and do they parallel wires or other nearby conductors? Are the antenna(s) properly connected and the conductors making a secure connection?

Most modern WIFI routers have enough signal, and your laptop enough capture. What we are doing here is thinking about what is getting in the way of a strong, clear signal getting from one to the other. These are the kinds of things that can block signal and cause such problems.

Another factor can be a Microwave oven, old CRT device like ancient monitor or television, causing an interference signal that makes your WIFI far less effective.

Hi wpeckham this has been on going problem for sometime now. I've checked that the TV is not interfering with the wifi signal.
I don't know what to do. I've tried other distros. Xubuntu, Fedora, and Manjaro same problem exists. The rtl_8723be driver seems to
cause alot of problems.

antenna needs (more) powerful antenna or a means to boots the signal and a powerful antenna

both really

oh yeah and a clear path like one mentioned about signal having to go through "solid" objects, distance limits too.

isn't that what repeaters are for ?

Please do consider the other factors. If you can move the router UP and away from all other nearby mass (walls, lamps, furnature, people) it can help a lot.
I have seen driver problems shut down WIFI totally, or make it unreliable. I have NOT seen a driver cause low signal strength.

Have you other WIFI devices? If so: Are they presenting the same symptoms?

On other threads it appears that you were advised to try a WIFI dongle, you did and resovled the probem. On another you appear to have been given driver advice that MAY have resolved the problem. My question is, if you have resolved this problem why are you brining it back up, or did you solutions not last?

wpeckham, I can't move the router because the tv box needs it to connect to internet.

There where problems with the wifi dongle that where causing problems every so often.

By the way everything worked fine with my last laptop. So this is just a wifi card problem on the laptop I assume.

antenna: I had on laptop that I could pop up the antenna to get a better single.

Antennas are not going to fix the problem. I need to be sitting right beside the router for normal browsing experience.
I can't move the router. What now.

In addition do you have any other device nearby that operate in the 2.4 GHz band i.e. cordless telephones or baby monitors?

If other wireless devices like a smartphone work at the same distance then it could be your laptop WiFi card has a hardware problem although I had router's WiFi go bad too.

Before you boost power or open the case and switch the antenna wire to the other connector, give thought to avoiding radio interference from other networks, not just appliances. Are you in an environment with a lot of other wireless networks within range in the same band? If so, which band are you using, 2.4GHz or 5GHz?

If you have the possibility, it would be most practical to use only the 5GHz band and avoid the 2.4GHz channels. If you and a neighbor are both on the same 2.4GHz channel, then you split the bandwidth. If you are both on interfering channels, then the performance is even worse. In such a case, find a 5GHz channel that is unoccupied and use that instead.

if not fix problem - cable is the only thing left seeings how devices cannot be moved to accommodate two items (devices) at the same time. or a repeater, something that picks up the radio signal then sends it on a different angle.

or Like little micro wave dishes placed in specif area's to give one that mirror reflection with light effect to redirect the signal around to here it is needed.

here is something to that effect has video to home make what you need even

BW-userx the same problem occurs when I use others distros. I take then that this a hardware problem. mostly

yeah hardware and its limitations. Not the software limitations because it is using the hardware limitations.

then you got a factor in the limitations of whatever is generating a signal to broadcast along with what type of signal that is.

because every signal is different.

wifi
satilight
micro waves
bluetooth
etc.

antenna types even.

then work with that.
