Thank you all for replies and advice Will try to give the answers to all your questions.
Do not have an Ethernet cable,Virgin took it away when they relocated my tv and Tivo Box last year to other side of lounge,They gave me the latest router which is plugged into back of Tivo.All the pc`s are WiFi.Yes my broadband is password protected.Also we have to switch router off from time to time.Hans,followed your link and there is no problems with my broadband connection etc.Many thanks for that.
I am now on my netbook which was playing up something terrible last night,it is rarely used (only on hols)but get it out from time to time to see if it is updated etc.This morning deframented it and it appears to be behaving somewhat better.
Am now awaiting to get my laptop back,grandson giving it a "dusting",he previously had speed problems with his and after having cleaned it out n,now works a treat...so fingers crossed,mine will be the same.
Intend to get my desktop done as well as that must be really stuffed up with dirt!!!!!
I get sooo frustrated when they are slow or keep freezing so I do hope things improve.
