surfing problems after replacing computer

Post by mintuser22 » Wed Oct 31, 2018 6:17 pm

Hello,
After my lenovo has been burned, a technician managed to move the hard drive,
with Mint 18.2 Cinnamon 64 bit and all the rest of the information on it to a new lenovo.
Everything is working well except:
After a few seconds of good surfing the browser says that "The site can't be resolved".
I can't update the device manager as well. The error displayed is "Failed to download pool data".
Update manager is working alternatively. now it is up to date.
Wifi is working well during all the time.
Firewall is off.
Pinging "www.google.com" returning good results.
Pinging "8.8.8.8" also returning good results.

Please advise

are you running a vpn? try changing DNS. this is openDNS you can change later to google or cloudfare or others. after applying and saving restart your connection (tick it OFF/ON) or reboot then after reboot what is nslookup linuxmint.com did it show you fast or did it take a few seconds

Code: Select all

208.67.222.222, 208.67.220.220

Not running a VPN.
Did the above but the problem persists - after a few seconds of regular surfing
the browser says "can't communicate with the server in address.."
Running "nslookup linuxmint.com" returning "connection timed out; no server could be reached".

sounds like you didn't finish changing the dns. can you show results to see if the changes are applied:
nmcli device show

don't take a picture of it. copy the Terminal writing then push the 5fth button above (code) this comment box and paste it in the middle of it.

your openDNS is active you can test here >>> https://welcome.opendns.com/ you should see an orange checkmark if opendns is used or red x if not.
the line IP4.ROUTE[1]: dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000 is in question. can you post what you have in /etc/hosts file? use the 5th button for the code. the one you use last was the fourth

nope, i don't see anything wrong with your /etc/hosts

the only this i can now think of is when was the last time you cleared ALL your history and cookies of your browsers?
and power cycle your router. unplug it for about 20 seconds. do you have a modem and a router or only one device?

Yes, all history has been delited.
The router has been unpluged, no modem.
Maybe something with the device manager? it's not up to date
and stucked when updated.

Disable power-saving on your wireless card.

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Change the contents to

Code: Select all

[connection]
wifi.powersave = 2
Ctrl-O and then enter to save, Ctrl-X to exit.

Reboot. Double - check powersave is off via iwconfig

Disable ipv6 for your wireless connection in Network Manager.

Might also be worth looking at your router settings. E.g on my router allowing the router to auto choose wifi channel creates havoc across a lot of my devices. This is because I'm urban and there are a a couple of dozen competing wifi networks in range and I think the router is often cycling through channels trying to find the best one (a futile exercise - they are all crowded).

Edit to add - on re-reading your original post and that your HDD has been moved from one machine to another - try with a Live CD of the same version of Mint - can you browse successfully from a Live session. If so consider backing up your user date and starting a fresh with a new install. May as-well got for 18.3 or 19 whilst you are at it.
