After my laptop goes into Sleep or Hibernate mode, when it wakes up the connection is always LIMITED. I try and disconnect and then reconnect but usually this does not work. I have to restart my laptop and then it connects ok. This is really annoying - I tried removing a setting that enabled it to disconnect from the internet to save power, but no difference. Don't think it is anything to do with the modem as a second laptop works fine. Running under WIN8. Any thoughts?
