Hello,
I have a VDSL / Fiber internet connection and my ISP supplied me with a normal router , I would like install a CISCO router instead,
I've searched for the configurations but no luck , I found an ADSL configuration that didn't work for me , would you please help with this , I posted a picture of my router WAN configuration page.
Thanks
04-26-2021 07:53 AM
what router is this ?
04-28-2021 04:00 AM
cisco 2921

Try this configuration example : ( who is the provider ?) - generally most provider give sample config.
05-09-2021 04:53 PM
Thank you so much balaji.bandi but the method you send it to me didn't work
My ISP didn't provide me with any templet or sample they told me that can't help me unless the device I'm using they did provide it.
I found some other page at my router I hope this page could be the key for you to guide me for the right configuration
I appreciate your kindness

just to clarify the image you attached a sample or your provider information? with the existing connection?
if the provider not given information, then you need to keep tweaking with different options to get it to work.
and debug is very important so we know what the router doing

after many attempts I could establish a connection but I couldn't get an access to the Internet, here is the configurations that get me connected

So would you please check it and tell me if you can find anything wrong , or what the next step could be
thanks in advance

these are Cisco general ping results :
"U" = Destinnation Unreachable
"." = The Network server/service timed out while waiting for a reply
"H" = Host unreachable
"P" = Protocol "
"N" = Network "
"!" = Receipt of a reply
"Q" = Source quench
"M" = Could not fragment
"?" = Unknown packet type
Can you post :
show ip route
show ip interface brief
Try are you able to ping your next hop address of ISP ?
