Laptop doesn’t see my router but sees all othersLocked
I have never seen this problem before… I own a store and have an Xfinity router/modem, one hardwired desktop PC, and a Sony Vaio laptop. The laptop has been connected to the xifinity wifi up until yesterday when a network cable was accidentally unplugged. Today, when I plugged the network cable back into the router, I was able to see the network on my iPhone and iPad, but NOT on the laptop. I tested by trying another laptop, and WAS able to see the xfinity SSID. So, the Vaio is the only device unable to see the router. The weird thing is that the Vaio sees every other router in range in the area. In short, I have a laptop that can see all routers except ours, and every other device can see our router. Is there some setting on the laptop that could have changed on its own when the network cable was disconnected? Anything else I should check?
Vaio is running Win 7 Pro 64-bit. If you require any more specifics, please let me know.
