Hi, Just thought I'd let you know that one of the IT guys at work looked at my laptop this morning and fixed the problem in about 10 minutes! Apparently he reset the TCP/IP stack (whatever that means!). Thanks again for your suggestions 
Hi, Hoping someone can help me with an issue I have with my laptop. About a week ago my laptop stopped finding WiFi networks.  I've tried switching the WiFi off and back on again on there and the standard 'Diagnose why Windows can't find any networks' claims that everything is working fine. I reset my broadband router and have also turned my phone into a WiFi hotspot, it's not picking up either (connected to both fine previously) or any other WiFi networks in the area. So suggesting it's a laptop issue, not a router problem. I'm really not very technical when it comes to these things so I don't really know where to start on this one. Suggestions appreciated!
