Short checklist and focused diagnostics to find the root cause of intermittent "No / Limited connectivity" (based on reporting a DHCP-based Spectranet link and asking about TCP/IP).

First, isolate the problem: is it one PC or the whole network? If only one PC, the issue is local. If several devices lose connectivity, suspect the router/modem or the ISP.

Quick diagnostic commands (run in an elevated Command Prompt) and what their results mean:

ipconfig /all
ipconfig /release
ipconfig /renew
ping <gateway-IP>
ping 8.8.8.8
ping www.google.com
netsh winsock reset
netsh int ip reset

Interpretation notes: a 169.254.x.x address means DHCP failed; successful ping to 8.8.8.8 but not to a hostname indicates DNS problems; failure to ping the gateway indicates a local link/router problem. See the ipconfig reference for details: ipconfig documentation

Next steps based on what the tests show:

  • If multiple devices drop: reboot modem/router, check ISP status, and test a wired connection directly to the modem to confirm upstream.
  • If only one device: update NIC drivers, disable any power-saving on the adapter, temporarily disable third-party firewall/antivirus, and reset the network stack (winsock/ip reset).
  • Check router DHCP lease table for duplicates or short lease times, and ensure only one DHCP server is active on the LAN.
  • For Wi-Fi: test signal strength, move closer, try a different channel, and check for many nearby networks causing interference.

A note about suggested "quick fixes": tweaks that change a NIC hardware setting or a Windows policy can sometimes mask symptoms but often do not address DHCP or wireless interference causes. Use the diagnostic steps above to gather evidence before making permanent changes, and log timestamps to share with the ISP if the fault appears upstream.

its a spectranet broadband connection.... that automatically picks up the IP address
but some times it shows no or limited connectivity...
Kindly suggest........

oops!
I think no one is good in ans
But i really got the one that works perfect
Method 1: Go my computer - manage - Device Manager - double click network adapter - properties - Advanced - select duplex- change automatic to 100 mbps

Method 2: Go to run - gpedit.msc - administration template - network analyst -
i dont remember the whole step but all we have to change 20 % reserve to 0 %
the internet speed will automatically increase...

It works try you good guys...
