Hi mr b if u have the same as me then it is white (netgear)and you can lie it down or stand up - if you look at the back there is a little black hole that you can insert a biro or pencil into .
i was told by sky to reboot you have to turn off both comp and router then turn them both on, as you turn on comp insert pen/pencil into reset hole in router for 15 seconds AS COMP IS STARTING UP and then test to see if same problem still occurs.
I did it and it worked for me, hope it helps.
you should be able to open your router settings in explorer usually type 192.168.0.1 into browser bar.once their you should see something like diagnostics and in that an option to rebbot router.
Mattk gives best advice. if 198.162.0.1 doesn't work try .0 or .2 at the end. It can vary by model but is typically within that range. There will almost certainly be a reboot option. mind you i do tend to just switch them off and on again if i have probs and this usually works.
Yeah don't reste it or you could end up with far more problems.
