Apologies to everyone whose blogs I regularly visit leaving comments - there seems to be a major fault with the BT cables somewhere & having believed it sorted (we had brilliant connectivity for a couple of days) we are back to almost impossible speeds.
I've spent the morning on the phone to our ISP & eliminating any internal wiring or router faults (disconnecting all phones, testing the Primary BT socket, using a different router, using a new DSL filter........) so that a BT Senior Fault Engineer can be called out without a charge of at least £99.99 to us. I have to call back on Monday to receive a definitive time slot for the visit. In the meantime I shall endeavour to enter challenges & at least leave comments where I have Wordpress email subs although my email functions aren't great either. Plain text isn't too bad but anything with a photo/picture/link or suchlike is a problem.
