Wi-Fi Interference from outside sources

  • Question
  • Updated 3 years ago
Recently I have been having reports of Wi-Fi drops outs i.e. clients being dropped from the Wi-Fi in a certain area of our college campus. After some investigation it would seem that there is a definite link between the reported drop outs and the regular train services that run adjacent to the building in question. I just wanted to see if anyone had any recommendations or prior dealings with anything like this?

That is interesting! Are the tracks electrified? Do you have a Metageek Channelizer or Airmagnet Spectrum XT? It would be interesting to measure the interference and see it in the spectrum analyzer.

Thanks for this. With regard to the electrified rail, as far as I'm aware, trains in the UK are diesel powered. That doesn't mean to say however that there isn't an 'earth' of some sort on the the track. I have a copy of Channelizer so will set up a laptop in the area and run some reports.

Another question. Did you replicate the drops? Is it on the 2.4GHz or the 5.0GHz frequency? 
It will be interesting to see what the spectrum analyzer shows.

Exactly this, you need to do some snooping as to what's going on in the air to decide how to move forward.

Thanks both for the input. I will relay my results when I have some...I'll start by looking up a train timetable!
