I have a windows 10 laptop: lenovo yoga that when I try to connect to a certain wifi router, if I ping while I connect, I get 5 or so good fast pings, and then they all timeout. Everything else can connect to this router. I tried connecting to 5Ghz or 2.4Ghz channel, and the same thing. I can't figure out why it would work for a second but then not work. I have tried disabiling firewall/defender but to no avail. Any ideas?

This is a newer Lenova Yoga with up to date windows 10 and drivers.

  • Is ping the only thing affected, or are there other consequences? Please don't make us guess. – I say Reinstate Monica Feb 4 '18 at 16:57

Any ideas?

Try completely reinitialising all network states.

Run the following commands in an elevated cmd shell:

  • Reset WINSOCK entries to installation defaults:

    netsh winsock reset catalog

  • Reset TCP/IP stack to installation defaults:

    netsh int ip reset reset.log

  • Reset Firewall to installation defaults:

    netsh advfirewall reset

  • Flush DNS resolver cache:

    ipconfig /flushdns

  • Renew DNS client registration and refresh DHCP leases:

    ipconfig /registerdns

  • Flush routing table (reboot required):

    route /f

  • It didn't work, but ended up just getting a new router. Thanks. – CptanPanic Feb 9 '18 at 13:26

Do you have a third party anti-virus product installed? If so, has it been updated to the latest version available? I've seen several Windows 10 systems suddenly loose most network connectivity after a recent Windows Update. Fixed by uninstalling the old anti-virus product. Still worked after installing the latest version of same anti-virus product.
