Some times just dropping the connection and re-establishing it brings the speed back.
Something to keep in mind is the "St James" has many different pockets which would be on different equipment. This could mean that someone else in St James is fine but everyone on your street might have issues.
As a first step, try resetting the gateway. This can be done be unplugging it but make sure you aren't recording or watching any tv at the time as you will lose your tv signal for about ten minutes. This can be necessary as sometimes the gateway MTS uses gets overloaded if you are making too many connections, commonly seen with peer to peer applications.
The other issue is with the warmer weather that bounces across the freezing point you could have water in your line. This is usually an issue in neighbourhoods where phone service is from overhead wires but can occur with underground wires as well.
If you have tried resetting the gateway and still have issues your best bet will be to contact tech support 204-CALL-MTS (204-225-5687) as it may require a technician be sent out.
