For those of you with the com wifi, I have been doing some tests, these tests have been using Montex and Texbase only not the Texecom server and still allowed access using the app or Wintex.
It has been a week without any failures being reported, and by early November it will be two week so I am almost convinced that the issue with the comwifi my end has been resolved.
If the comwifi has been set as recommended in the manual, I was still getting failures, however changing the settings didn't appear to have any long term effect.
So with everything set as recommended and the comwifi network forgotten, ie the pc can not log into the comwifi network automatically or even manually without putting in the password yourself, it appears to have stopped the failures completely over the last week.
Why forgetting the comwifi network has made this difference I do not know, if anyone has any ideas on why I would like to know.
In early November if I still haven't had the failures I will be connecting back to the Texecom server as I believe I have my end resolved, I suspect it will perform similarly to the comip module at that point.
