I've had a few people saying that their broadband is slower than normal at home.
This can be because you are normally not working from home at this time of day but more likely due to the increased volume of people using the internet for surfing, watching Netflix, Prime, YouTube, etc.
First, try rebooting the router, check the microfilters on phone outlets and try an ethernet cable if wi-fi is poor.
If you are using a laptop over wi-fi and you also have a smartphone with a decent 4G signal then try creating a local HotSpot on the phone and then connect your laptop to the hotspot rather than your normal router.
See if things run any quicker
Remember to check your data tariff and allowance though
