I'm having trouble keeping my lenovo laptop (running windows 8) connected to the internet, and hoped someone might be able to help. I have been able to connect successfully to multiple wireless networks and access the internet until I tried to connect to the new network.
Initially everything is OK - I can connect to the network and access the internet. However after a short period of time (anywhere from a few seconds to 20 minutes) the network connection will change to limited, without internet access. If I simply disconnect and reconnect to the network the internet will immediately be working again (at least for a few seconds/minutes).
Alternatively, if I run the troubleshooter, I always get the message that the default gateway is not available, which has been fixed by resetting the wi-fi adapter.
Any advice would be greatly appreciated. Please let me know if there's any more information you need.
