Slow WiFi: how do I check DHCP service logs?

[kalevala]

@kynes:

Do you have any iOS device? There is an app called Fing that tells you all the devices connected to your network.

Kynes knew you would be the first to respond XD

I have an iPhone, I will download the app and when I get home this afternoon I will try it out…

Thanks!

I use this kind of apps every day ;D

For Windows, you have look@lan, which tests all the IPs in a range that you define and tells you which computers are there.

When I need to access my father's PC via VNC and the DHCP has given him an IP that I don't know, I "search" for it with this program. It works very well.

Thanks Mystique, I'll take a look in case it's useful for work

Is it that easy to steal a wpa2? I'm going to try the little program that seemed interesting to me but I had never downloaded it. PD. http://www.ixpiabot.com/wifikill-bloquea-a-otros-usuarios-de-tu-red-inalambrica-android/ this is the last one I had seen.

To make sure it's someone stealing your WiFi, you can also enable MAC Filtering on your router and use it as a 'whitelist'. In other words, only allow the MAC addresses you specify to connect to the router. It can be a bit of a hassle if you have many devices or receive friends robawifis, but if the DHCP log issue doesn't help you, with this you should be able to tell if your WiFi has been hacked.

It helps, but they can clone your mac. The safest thing is WPA2+Mac Filter+delete DHCP+put a weird range like 192.168.43.xxx+Don't broadcast the SSID, but all this together is already a bit paranoid (my father-in-law)

The wpa2 that comes by default on telefónica or jazztel routers can sometimes be "cracked" with the key generators that exist, a complex wpa2 (more than 8 characters, with numbers, uppercase and lowercase letters and symbols) is not easy to crack by brute force, you need a lot of computing power, but the problem is that there are programs that use the graphics and it is getting faster and faster to break the WPA2.

Your father-in-law is a machine, he looks like me, who to kill a fly uses a tank "to reduce the margin of error" :ugly:

The WPA2 that comes by default, there was a trick related to the MAC, and is that (at least before it was like this) the MAC corresponded with the first and last part of the key, leaving only to find out two characters in between, but of course, between alphabet and numbers you could spend a good time…

Best regards

My father-in-law is a distance professor, at a university in the USA, of subjects like linux shell, virtualization and cloud. His three daughters have turned out to be literature majors, so he loves to talk to me about computer science topics.

And don't forget to change the password every so often Before I get into paranoid mode (I have the same problem with my father-in-law as you do with yours xD) I would change the password every day, auto-generating a few alphanumeric ones and changing them.

If you plug in the RJ45 and leave the WiFi on, does it also work slowly? Let's see if it's a router problem or the "environment" (my Livebox 2.1 does strange things to me in my block many times).

[Mystique]

what i advise you, if you go into paranoid mode, is that you change the ip range. everyone uses 192.168.0.0 or 192.168.1.0

if you go to a type A network (10.0.0.0) and play with the network mask, it will be more difficult

With the RJ45 and wifi active on the router my pc flies (obviously, because of the network cable)

The explanation that the idiots from Comcast give me is that if there are many routers in the building (there must be 500 more) the interferences make the connection slow and there is nothing that can be done to improve it: reading between the lines, they don't have a clue about what is going on and the technician they sent to my house just said that the cables were a little "loose", balls…

As soon as I have time I will get into the subject, I have been working all weekend without stopping and I have hardly stopped at home

Regards and thanks for the help!

Comcast, ono, telefonica… NOBODY is going to guarantee you a speed over wifi.
The problem today is that everything uses wifi and the air becomes saturated and can't give more of itself. It is what it is

What kind of router do you have? They are partly right, there is a problem with wireless connections known as fading, but for that they perform frequency hopping. One of the advantages of N and AC is that it partly avoids this kind of problem, if your wifi router is G it may be part of the problem.

That said, if you have a lot of wifis in the building, the only thing you can consider is broadcasting on 5 GHz, which is much less saturated, although it has the problem that penetration through walls is much inferior, so you usually have less coverage.

[deeiivid]

The solution is the rj45, if necessary, with PLC.

I live in a student area, and there is no range or channel that is not saturated... and the wifi connection is pure garbage.

We even have cables outside the windows :ugly:

As they tell you above, the ideal is to broadcast in 5ghz, but do not expect much range.
