One Win10 PC stopped getting wireless internet, everything else ok
Iam trying to help someone with this issue.
OneWin10 PC stopped getting wireless internet form her modem-router.
Itcan get internet from the same router via LAN.
Itcan get wireless internet from a hot spot.
Other,android devices, work fine with this router wirelessly.
It doesconnect to the WiFi, but with no internet (yellow triangle).
Itdid work in the past.
Itclaims the IP is already used by another device. It is configured to get it automaticallyfrom the DHCP, but I also tried assigning one manually, within range.
Ipconfigrelease/renew won't work.
Resettingthe modem-router did not help (also by the internet company, that claim it mustbe the PC's fault).
Changingthe network's SSID did not help.
Obviouslyrebooted PC and reconnected.
In ipconfig,ipv4 IP isn't showing, but using ipconfig /all, it does show a number + "(duplicate)".
In theevent viewer it repeatedly complains about 192.168.1.26 used by MAC x, but on earlierdates it was .27 and MAC y. Neither x, nor y are listed on the router's DHCP table.
DHCPservice working and set to auto.
I disabledWindows' firewall.
Itried to reset TCP/IP by Microsoft's orders.
WiFiadapter is Intel's wireless N 1030. It found no better drivers. I uninstalledit, but there was no box to delete files. I installed the latest from Intel'swebsite, but no change.
Anyidea what went wrong?
As it'sa long drive, I'd be happy to get as many things to try at once.
Thankyou!
