Hello,

If you switch between networks during the test there might be connectivity issue which might interrupt the test. According to the instruction given in https://vit.ac.in/files/VITEEE-online-guidelines.pdf

the network must be stable with minimum upload/ download bandwidth of 256 KPBS should be available for the duration of the two hours. Not more than 5 minutes interruption is allowed or else the test session will get terminated and there will be not be given any chance for retest. Keeping that in mind we would suggest you to not switch between network frequently.
