It arrived today, and I immediately spotted something wrong. Checking the listing, I could see it was my mistake, and not the seller.
I had determined there were two Vigor routers that would do what I wanted, and had searched eBay for them. Many were 150-175 pounds, but on seeing a used model currently bidding at high 40’s (I got it for 52), I put a bid in.
Only now do I realise that this is the non-WiFi version of the router.
As it happens, I am not too concerned. It is still worth the money, it just means my WiFi will be handled external to the router, rather than built in. I already have a Fon wifi unit, which I keep plugged in mainly to make me eligible to use other Fon units when I travel. In fact, having this positioned in my lounge, rather than the upstairs office might even be an advantage.
However, it is a lesson – don’t let your enthusiasm for a bargain trump your reading skills.
