Dropping data strength

The low rating is due to the inaccessibility of Vodacom's "log a query" service. This is suppose to be part of their app so as to make it easy to log a complain. The complain I would have liked to log is that my data strength at home dropped significantly over the last week. After spending a lot of good money to install a Wi-Fi system, I must now move the rooter every now and then searching for signal. Perhaps I should consider moving to the opposition.
