[bukolaj]

Hello , Please I need help with my vodafone router or the connection . Since I got it in December , every day it will stop to work by itself and I have to disconnect and reconnect before it works again . 

Kindly help me look into this issue as I need it for write an exam at home and now I am worried so it doesnt disconnect me during the exam . I have been used to always restarting each time it happens , but i cant do that because of the exam so I need a solution . Please help
