I have a Netgear DG834G Modem/Router and I switch it off when I am not using the internet.
I was browsing the web yesterday and I saw an article on the BT website which included the following:
“Important note about speed tests
Every time you switch off or re-connect your router or modem, your broadband service refreshes your connection speed. Note, however, that where this has increased, your throughput speed will not increase for a further 3 days. This is to minimise the risk of data loss which would occur if the exchange tried to send data down your phone line at a faster rate than it is capable of handling.
To avoid this happening, your exchange waits for three days of consistently higher connection speeds before it will increase the speed at which it passes data down your line. Also note that if your connection speed dips for any reason during the three-day period (eg. due to electrical interference or a fault), the exchange will re-start the three-day period.
For these reasons we recommend you leave your router switched on all the time, and avoid measuring your throughput speed until three days after you last switched on or re-booted your router or modem.
What to the TSF Gurus think? Should I leave it switched on all the time, or doesn’t it matter?
I should add that my ISP is TalkTalk, not BT.
