The reason I ask is my 'up to 8mb' ADSL has become very slow recently (371kbps this afternoon). I rebooted the router and the next test showed 3591kbps and the next 4562! All in the space of 10mins. So, if switching off and on was the reason for the improvement (persuading the kit in the exchange to re-think the connection condition?), how often should it be done? Thanks as always.
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 a 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.
we live and learn, my BT went down to a crawl, messed around with everything on the two laptops, gave up in the end and got it touch, via email, to BT, and what did they say, switch of the router and let it reset, I had my doubts, anyway I tried it, and lo and behold, back up to speed, nice one BT...
in 12 months my homehub has twice become painfully slow, the 10 second turn off worked both times. it's meant to be fixed now, it was a problem with the software updates blocking something so bt tell me. last happened a couple of months ago.
