Wifi never connects
I Don't currently have home wifi as I moved house so I went to my local library. The wifi never connected, the wifi symbol was continuously flashing as it does when it's connecting but the connection never established. I thought it was a problem with their wifi so I came to my university which is a known network on my MacBook and the same thing is happening. I have reset my pram and restarted my laptop but the wifi will not connect. any help is appreciated as i really need to access the wifi ASAP.
