And it was not my laptop. It was the last update the router maker put out. I was puzzled but found other PCs would connect and something truly odd is that my machine would connect if I turned on my Kindle Fire HD.
Off to google and sure enough folk were reporting issues with that router maker.
Thankfully the fix was easy. And the symptom of resetting then it worked is the same so let's hope you can tell more about the router.
My laptop is having trouble connecting to the internet. Some of the time it is fine, but at other times it will not connect to my home wireless network (or any other open ones I can find) despite the network being in full signal.
The only advice offered by the troubleshooter is to reset the wireless router. This does work (but is very irritating to flatmates!) but doesn't prevent the problem recurring. Only my computer has an issue, and sometimes it will manage to connect to the internet by itself, seemingly spontaneously. The laptop is set to connect automatically, and when not working it also does sometimes attempt to connect, (i.e. it says 'connecting') but cuts out again before managing it. The problem can last for a few minutes or several hours.
Any suggestions about whether this is likely to be a software or a hardware problem would be much appreciated. It has been dropped a few times. And if there's any useful information I can supply to help diagnose the issue, just let me know what's needed.
