Q: Wifi Connected- Only Chrome works?

Hi, so recently the internet on my macbook air 13 (early 2014, 1.4Ghz Intel core i5, 4gb RAM) running on OSX 10.10 has not been working.

It works perfectly connected to my phone but not on the mac, therefore it must be problem some with the mac.

Wifi is connected, internet works perfectly on chrome and skype but nothing else, despite a little bit of lag.

Can't connect to mac app store, safari, spotify... etc.

Did a Network Diagnostics

Wifi: Green

Wifi Settings: Green

In System Preferences > Network

Wifi Status: Connected

TCP/IP:

Subnet Mask: 255.255.255.0

Router: 192.162.2.1

Nothing from proxies checked

Hardware:

MAC Address: 48:d7:05:e6:90:8f

Tried restarting mac and router, resetting router, flushing dns, recreating network (with new location), changing DNS servers (i.e. google 8.8.8.8)

Any ideas on how to fix this?

Many Thanks

(Sorry for the long post)
