Hi all ,
I am in an funnny problem & am not able come to solution from last two days, i have two wifi(WLAN1 & WLAN2) connections in my building which i can use & one ethernet cable of the ISP which is connected to the WLAN1.
I am using ubuntu 16.04 with following network configurations
From last two days i am not able to use the internet using the wifi , but when i plug the cable provided by my isp directly into my ethernet port , internet is working, but not through wifi.
I researched more & i tried to Ping 8.8.8.8 & Ping google.com following are the results in both the WIFI's i am having
WLAN1
Similarly i tested the same commands in the Second Wifi at my home
WLAN2
Friends as you can see both the wifi's WLAN1 & WLAN2 is behaving differently
i.e ping 8.8.8.8 & ping google.com is not working in WLAN1
ping 8.8.8.8 is working WLAN2 but ping google.com is not working in WLAN2
But the internet is working fine when i connect the ISP's cable directly to my ehtherent port
I am frustrated trying everything i researched in these forums from last two day but nothing is working ,
Following are the some more info on the commands i executed in WLAN1
Anyone kindly suggest on how to overcome this problem
Thanks & Regards
Vaibhav
