I have a fresh install of Ubuntu 20.04. Connected to ethernet getting dhcp setting automatic from modem.

Gateway 192.168.2.1 Ubuntu 192.168.2.100 Home device 192.168.2.21

Home device is able to connect to internet no problem.

Ubuntu cannot get online.

Home device can ping ubuntu and receives response successfully.

Home device ping to gateway Success

Ubuntu ping to home device Success

Ubuntu ping gateway Nothing

I have been pouring over documents for days. I have hard reset modem. I have whitelisted the ubuntu. I have sudo disable ufw I have tried multiple cables.

I am at a loss. Please help

The output of ip route:

Please [edit] your question to include the output of `ip route`

Your default route is set with very low priority ... I don't know if that is the culprit, but try deleting it and adding it again to compare ... `sudo ip route del default via 192.168.2.1 dev enp6s0` and then `sudo ip route add default via 192.168.2.1 dev enp6s0` ... Also please add ith output of `ip address`

After reading other issues similar to mine like this.

ubuntu 20.04 server not responding to ping

I decided to try a new IP address and I have no idea why, but it worked.

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.
