I am on puppy Linux which isn't quite configured with all Ubuntu utilities and defaults
this problem happens repeatedly especially after I bring my laptop out from sleep
I don't know what I do but it will go away eventually but hanging around for quite some time and don't know what made it go back to normal again.
right now I am stuck
connecting to the internet through my mobile hotspot.
problem
I can ping my default gateway my nslookup and others suggest that DNS name resolution seems to happen but I cannot ping externally and obviously there is no internet what seems to be the issue and how do I get online
what I did sofar
change to static IP. flush IP route and cache. turn off turn on my my Wi-Fi adaptor physically on my laptop.
the standard DNS flush procedures do not seem to work here on puppy Linux but I haven't tried hard because DNS seems to be resolving . also I uninstall firewall right now there is no active firewall as IP tables listing will suggest
thank you Manish for your input - since you can't go beyond default gateway the problem should be with my router actually my router is a hotspot so not many options to change stuff in my Android phone neither do I think that is the problem. I can use the same hotspot the same client MAC address but through Windows connect to internet successfully. also so all other clients can access internet through my hotspot.
here go all the
command outputs that would be needed
