If you have modem with router functions and also have a router then the modem's router function (providing DHCP IP addresses) should be disabled.
Only the router should be providing DHCP IP addressess.
Is the following line diagram correct?
ISP === (coax, DSL, fiber) ===> Modem ---->[WAN Port] Router [LAN Port] ----> [LAN Port] Office Wifi Access Point ~~~~> Wireless network devices
With other Router LAN ports -----> Wired network devices
Edit the line diagram to correct as necessary.
For example: is your PC connected to the Router via a LAN port? Is there a Wifi Access Point?
On the PC double check that only the wired network adapter is enable and that IPv6 is disabled.
Also check that the wired network adapter's Speed and Duplex is set to Auto Negotiation.
TCP is still disabled/uninstalled -correct?
IPv6 is still disabled - correct?
Run and post "ipconfig /all" to show the current configuration settings.
Also run "pathping 8.8.8.8" via the Command Prompt and post the results.
Yes the diagram is correct.
I m connected with lan.
TCP is completely disabled and deleted.
IPv6 is disabled.
