Internal wiring faults
Internal wiring can have an affect on your speed. Broadband is very susceptible to interference from both electrical and radio interference. Common faults found in your premises that can affect your service are:
Extension cables (unbalanced)
Poor quality telephone sockets and connections
Faulty thermostats that controls central heating and immersion heaters
Christmas tree lights
Satellite and free view boxes
PIR security lighting
Power leads and equipment near broadband equipment
Equipment faults
Modem/router faults - Try resetting your modem/router, as with most electronic equipment, they can be prone to lock-ups (freezes). Make sure all your settings are correct; these can be confirmed with your Internet Service Provider.
You could even have a faulty modem/router or filter.
Firewall's - This is software that protects your computer by blocking and permitting programs access to your computer. Recent upgrades could possibly block you access to the internet.
Viruses/Spyware - These are programs that can infect your computer and can even prevent your browser from working. Make sure that your anti-virus software is up to date.
Reading this it all sound a bit depressing. So what do we do next? The key is to ensure that as with all problems note if there are certain consistencies with your problem i.e. the time of day etc. Confirm with your ISP what service you have and what speed you should be receiving ask them to have your line tested. (many customers do not know what type of service they have).
If you have received a fast connection in the past, ask yourself have you changed any wiring, added a piece of equipment or maybe your ISP has changed your service or facilities. Check that you have filters in all sockets that have telephone equipment plugged into them.
It could just be that the new house is served by an exchange with different equipment not able to produce the speed you had in your old place.
I have a stable 7mbps line and can only dream of your former 19mbps.
