And enable the option to only allow your PCs so no other devices/PCs can use your wireless connection. You will look for the option of MAC Filter List then enter only your PCs MAC address.
And I hope the router is pass-phrase protected also.
I have been warned by talktalk that last month that I downloaded 90.1gig which exceeds their 40gig monthly broardband allowance,and will be charged extra if it occurs again.
My setup comprises 1 dell desktop with McCafee,1 HP laptop with AGV, wireless networked via a Netgear DG834G modem. My wife and I are retired and never download music and films except occasional BBCiplayer which would never exceed 10gig/month. It seems to me that someone has accessed my connection. How can I prevent this happening again, or could their be another reason? Step by step solutions please.
