I updated my MacBook Pro (16-inch, 2019)
to latest macOS Big Sur - 11.3 (20E232)
and right away started to experiencing some network issues such as this:
alexus@mbp ~ % time host google.com
;; connection timed out; no servers could be reached
host google.com 0.00s user 0.00s system 0% cpu 10.010 total
alexus@mbp ~ % grep ^nameserver /etc/resolv.conf
nameserver 192.168.86.1
alexus@mbp ~ % netstat -rn | egrep 'default.*en0'
default 192.168.86.1 UGScg en0
alexus@mbp ~ % time ping -c1 192.168.86.1

writing you this question to you fine community)
a lot of apps opens slow (~1-2 mins), definitely not as quick as they were before (1-2 secs), App Store
never opens...
Please advise.
