Wifi Connected but no Internet Access on Ubuntu 21.04

pk flag

Hi i have dual boot with windows 8.1 and Ubuntu 21.04 Desktop 64-Bit

I am using windows to ask this question as my Ubuntu WiFi is not working.

It was working fine for the past 7 days, and dont know what happened suddenly.. I am using my mobile Hotspot to connect to the internet on both Systems.

Here are my configs:

Ubuntu OS Version

iwconfig:

iwconfig

ifconfig:

ifconfig1 ifconfig2

ip address:

ip addressess

I had changed some DHCP Settings prior so maybe it could be a culprit ?

ls etc/dhcp

my etc dhcp.conf file ( i am only showing the lines which i have edited)

default-lease-time 600;
max-lease-time 7200;

authoritative;

# A slightly different configuration for an internal subnet.
subnet 192.168.43.0 netmask 255.255.255.0 {
  range 192.168.43.100 192.168.43.255;
  option domain-name-servers ns1.internal.example.org;
  option domain-name "internal.example.org";
  option subnet-mask 255.255.255.0;
  option routers 192.168.43.255;
  option broadcast-address 192.168.43.255;
  default-lease-time 600;
  max-lease-time 7200;
}

i have tried disabling ipv6, but still problem persists. Please Help :)

Please [edit] your question and include all text as text, formatted as code blocks instead of showing screenshots. Do you have a DHCP server running on your Ubuntu system? I would expect that your mobile hotspot is the DHCP server and your PC should run a DHCP client which should normally work "out of the box". What configuration related to network did you modify? Please [edit] your question to answer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
