[ubuntu-in] Wifi behaving Erratic: SOS

[Ritesh Sinha]

Another way to (slightly to greatly depending on your network)
increase performance on networks that take very long for DNS
resolutions is to use BIND server installed in a caching only
configuration, with the OpenDNS server (or another DNS server) set as
forwarders.

For instructions on how to accomplish this, have a look at

https://help.ubuntu.com/community/BIND9ServerHowto#Caching%20Server

After you set this up, you need to modify /etc/dhchp3/dhclient.conf
and modify this line
prepend domain-name-servers 127.0.0.1 (uncomment it if it is already
commented). This is to ensure that NetworkManager always assigns your
local system as the most preferred DNS server.

I have achieved great speedups in DNS lookups (you can test this using
dig). Try it at your own risk, though.


Regards,

Ritesh
