[thedighubs]

Good evening

Well I have some issues with the field power ... Of the WLAN.

I am on Linux.Which tools for wireless network monitoring do you recommend?

What can be used from the laptop or desktop system to find out wifi network speed, signal quality/strength?
What command would show much useful information?

Any recommendations?

I prefer "WiFiAnalyzer" on android. Green icon with white shapes.
