Hello. I have been using Opensuse leap 42.3 for months without a
problem; but a few weeks ago, browsing the internet began to be slow,
sometimes impossible to access some web pages, in a random way,
sometimes also without issues.
I know that the interner connection is OK (ADSL) because I can browse
correctly with Windows 10 and android (smartphone). The problem is the
same with Firefox,Chrome and Opera.
It is possible that this began with a DHCP security update, but I am not
sure.
I don know how to begin to explore this issue.
Thank you in advance.

Try to disable the
search DSL-100HN-T1v4
by commenting out with the # in /etc/resolv.conf

I have edited the file and everything seems to be OK; browsing is fast
and reliable; but I need to test it for a longer time, because the
problem fluctuates with time.
Thank you for your quick reply.
Especially for the case of an IPv6 router, you may need to change something in the network configuration file “/etc/sysconfig/network/config”:
## Type: string
## Default: ""
#
# Allows to specify options to use when writting the /etc/resolv.conf,
# for example:
# "debug attempts:1 timeout:10"
# See resolv.conf(5) manual page for details.
#
NETCONFIG_DNS_RESOLVER_OPTIONS="inet6 edns0 single-request single-request-reopen"
These options then get written to “/etc/resolv.conf” at boot time: “options inet6 edns0 single-request single-request-reopen”;
- as well as the Name Server’s IPv4 and IPv6 addresses determined by DHCP …
