Strength of network(Wifi) affects TF?

edit

Lately when I use waitforTransform , I've been getting TF errors, basically terminal inform me the transform could not obtained. I wish to ask if waitforTransform is affected by bad network, in this case wifi? Because most times I don't get this error at all. Error:

tf2.TransformException: Lookup would require extrapolation into the past.  Requested time 12381.405000000 but the earliest data is at time 12402.963000000, when looking up transform from frame [map] to frame [base_scan]

I'm using a simulated robot in gazebo, so everything is being done on one machine. The wifi seems to work fine for everything else, no clue whats going on. Could it be some NTP synchronization thing?
