Hi there,
Bit of a coincidence that this only began after your upgrade but the rest of the information you give almost rules out your laptop being the issue.
Also the error you get being 'limited' tells me that you are not losing connection to the router. If you were then the error would be 'unidentified network'.
However, if something has gone wrong with windows networking it would affect both lan and wifi and might say limited as well. Limited means it's connected locally but the internet is down.
If the Internet is not going down and the light on your router is blue then it's unlikely it's the intertnet connectivity, although again you can't rule that out. There's not enough information to give you a definite answer so need more info:
- Have you installed any anti virus? if so, uninstall it and test. Windows has a good level of security so it's fine to run without 3rd party AV, at least for this testing phase. Some AV interferes with the built in security windows provides and can adversely affect networking.
- Can you ping the router when it is limited? (hold the windows key and press 'r' type cmd then type ping 192.168.1.254 into the black window) do you get replies when limited? also can you ping 8.8.8.8 ?
- What fixes it? rebooting the router or the computer
Thanks
