Currently on Virgin Broadband. My connection is as reliable as a party manifesto pledge during a recession. But I'm not worried because I have the ever helpful Virgin Support Centre on hand:
"Hmmm, is the router plugged into the mains sir?"
"Is it switched on, sir?"
<cue grinding teeth> "Yes."
"Have you plugged the router into the phone socket on the wall?"
"I'm sorry sir, I'll have to escalate your call to one of the senior team."
<cue 15 minute wait>
"Hello sir, is the little internet icon visible in the toolbar?"
