I seem to remember reading about there being a fault with many iPhone 4s's wifi antennas, suspect that's at fault and will need replacing. As you got it on ebay hopefully you can return the phone for a refund?

Similar/same happened on my work phone. I think it's a hardware issue so no amount of software resets will work. I ended up following a 'tutorial' that says to heat it hot, hot, hot with a hairdryer in a particular place to try re-flow the chipset solder inside. It worked again for a time but then failed again a month or so later.

Edit: as it was a work phone I had nothing to lose if I broke it more, they were replacing it anyway.

I had this too back when the 4S was the currently model. I took it to Apple and they swapped it out for a replacement.

Unlikely to happen when it appears the OP has bought an old phone second hand from eBay.
