I've 80mb fibre at my workplace, and I get almost full speed.

But it gets slower and slower over the course of several days to the

What would cause this? Stuff beyond my control, or is it possible it's
my gear?

It's not a fancy setup, Technicolor router with a couple of PCs plugged
in and a downwind switch with a PC and a printer plugged into that.
Laptop and mobile connecting wirelessly.

What could cause a network to clag up?


I have seen several routers where wireless lan usage causes the
behaviour you describe. I guess this is caused by a resource leak. These
lost/leaked resources are restored when the router is rebooted.

Regardless of what exactly is causing the problem it might be that as
long as you reboot once a day the problem never occurs. So rather than
wait for a slowdown reboot the router each night and see if the problem
remains.

If this does solve the problem you will be reasonably confident it is a
problem with your router and can either buy a new one or just continue
rebooting it once a day.
