Wifi not working on many trains?

For the past two weeks I have had a fair few services where the Wifi just hasn't been working (as in it's not even present despite the stickers).

Is there a reason for this?

  • MarkS.  This has also been my experience.  For the last few months I have not been able to join the SWR WiFi.  I seem to be able to join the entertainment site, but nothing happens thereafter, it is as though the whole system stalls.  For several years, up until about February this year the WiFi was good, and I had many productive hours on SW trains.  Any insights that anyone can give would be helpful.
