My exchange is BT only and I renewed my contract and got a shiny new black hub and the phone. Hub works very well and the broadband phone is a great addition, crystal clear calls for free on a night etc so chuffed. Anway came home wifey moaning no dial tone. Fair enough I'm Sigs will have this fixed in a jiffy. A bit of fault finding and I got dial tone back, It was the hub, its creating an open circuit (short) so dropping the line. Bugger, not so much its the hub, it just needs replacing but bugger I'm going to suffer the idiots at BT's call centre on the other side of the planet. I gets a young lady, awesome pidgeon english a 5 minute call is taking 45 minutes. She is convinced the fault is I cannot use broadband and make a call at the same time, I keep repeating the hub is faulty and it drops the line. Ive hit a wall and she carries on to say an engineer will call becuase broadband uses high frequencies and this can interfere with calls (yes love thats why we use filters and guess what mine are fine). I pops out my trusty belkin plugs up and I'm back online within 5 minutes. 2 hours later BT's engineer rings up... BT, your internet is working ME, yes a temporary fix, I plugged in an old router BT, old router? ME, yes the router I used to use before I got the new one BT so you internet is working ME, no, the new hub you sent me has a fault, it drops the line as soon as you plug it into the filter. BT, Ok did you use the cd? ME, No its a hub and Im not thick, BT, no CD? ME no CD, I plugged it in checked config and was away. It worked fine until today. BT, can you plug it in and tell me what lights are lit. ME, If I plug it in it will drop the line, the hub is causing an open circuit. BT, can you plug it in and tell me what lights are flashing ME, the hub causes a line fault if I connect it I will lose this call. BT, so the broadband light is flashing? ME, 2 secs (gets ready) ok when I plug this in the line will drop are you ready? BT yes yes plug it in and tell me whats flashing... ME, plugs it in... line goes dead... ME, TWAT!
