Bardzo częstym problemem który pojawia się na naszym forum jest niestabilny dostęp do sieci bezprzewodowej w naszym domu/mieszkaniu. Aby móc cokolwiek powiedzieć w tej kwestii trzeba wykonać diagnostykę takiej sieci i spróbować znaleźć co jest przyczyną takiego zachowania się sieci lub urządzeń próbujących z nią połączyć. TEST 1 - pomiar sygnału Podstawowy test od którego musimy zacząć naszą diagnostykę sieci bezprzewodowej. Aplikacja umożliwia nam śledzenie poziomu sygnału z naszego routera/punktu dostępowego. Jednocześnie możemy obserwować jego stabilność w funkcji czasu oraz zakłócenia od innych sieci bezprzewodowych będących w naszej okolicy.

Pamiętamy aby wyłączyć w tym czasie wszystkie aktualizacje czy programy p2p (torrent) tak aby łącze nie było obciążane przez komputer.

Program nawet sam wskazuje potencjalne problemy z komunikacją oznaczając kolejne węzły na pomarańczowo lub czerwono gdy są widoczne problemy lub opóźnienia. Możemy z tego szybko wywnioskować że jeżeli pierwsze punkty komunikacji są na zielono (wszystko zależy ile mamy urządzeń u siebie) to u nas jest wszystko w porządku i nie musimy się martwić naszą siecią. https://obrazki.elektroda.pl/4640097300_1611490109.jpg Wszystkie wyniki powyższych testów wklejamy w naszym wątku na forum w postaci printscreen-ów - Link - pamiętamy też o dokładnej informacji o modelach urządzeń z jakich korzystamy w sieci (router bezprzewodowy, punkt dostępowy, karta bezprzewodowa) PLIKI DO POBRANIA:
WinMTR – Appnor's Free Network Diagnostic Tool - http://winmtr.net
Thank you for downloading WinMTR v0.91!
*** About ***
WinMTR is a free MS Windows visual application that combines the functionality of the traceroute and ping in a single network diagnostic tool. WinMTR is Open Source Software, maintained by Appnor MSP, a fully managed hosting & cloud provider.
It was started in 2000 by Vasile Laurentiu Stanimir as a clone for the popular Matt’s Traceroute (hence MTR) Linux/UNIX utility.
Read more about WinMTR’s history: http://winmtr.net/history/
*** License & Redistribution ***
WinMTR is offered as Open Source Software under GPL v2.
Read more about the licensing conditions: http://www.gnu.org/licenses/gpl-2.0.html
Download the code from: http://sourceforge.net/projects/winmtr/
*** Installation ***
You will get a .zip archive containing two folders WinMTR-32 and WinMTR-64.
Both contain two files: WinMTR.exe and README.TXT.
Just extract the WinMTR.exe for your platform (32 or 64 bit) and click to run it.
If you don’t know what version you need, just click on both files and see which one works ;-)
As you can see, WinMTR requires no other installation effort.
Trick: You can copy the WinMTR.exe file in Windows/System32 so it’s accessible via the command line – cmd!
*** Usage ***
Visual:
* Start WinMTR.
* Write the name or IP of the host (e.g. google.com)
* Press the Options button to configure ping size, maximum hops and ping interval (the defaults are OK).
* Push the Start button and wait.
* Copy or export the results in text or HTML format. Useful if you want to document or file a complaint with your ISP.
* Click on Clear History to remove the hosts you have previously traced.
Command line:
* Run winmtr.exe --help to see what are the options
* Run winmtr hostname (e.g. winmtr www.yahoo.com)
*** Troubleshooting ***
a) I type in the address and nothing happens.
Usually this has to do with lame anti-virus or firewall applications. Stop all that when doing debugging or when using WinMTR. Or, configure them properly.
b) I get an error saying the program cannot be executed.
You are running the 64 bit version on a 32 bit platform. Try the WinMTR.exe stored in the WinMTR_x32 folder.
c) I get an error unspecified here.
Please report it to us to make sure it’s not a bug in the application.
