networking performance issue(s)

Recently, and I don't know if this is the fault of Windows or
of changes that Spectrum may have made, web surfing has slowed down. I
can watch the process in the corner of the screen when I click a link
and the steps that used to happen instantly take several seconds or
stall completely partway through. My system has also grown cranky
connecting to the net in the first place when the system boots.
Sometimes I have to disable and re-enable WiFi several times to get past
the "connected but no internet" problem. For fun(?), I tried disabling
IPv6 in network properties for the WiFi adapter. This has gone a good
way towards restoring performance. So, my questions a is IPV6
generally necessary and could disabling it have caused the performance
improvement I'm seeing or is that just a coincidence?

The enemy of wifi is other wifi applications running nearby.
A strong signal will drown a weaker one, and you find out, that
your connection becomes unreliable.
If possible, use a cable or install a nearby repeater.

I don't think that's the problem. Our home is far away from our
neighbors and monitoring equipment shows NO other "competing" WiFi
nearby. My Velop router (3 units) produces a very strong signal so
I don't believe that's the issue.

No competing wifies in the house?
digital TV, cameras, M$ trying to update computer(s) etc. ?

those aren't competing.

I don't know about your digital TV but mine has its own router and shows
up as another net work.

What ever you may try to change the channel that your router uses, and
see if that works. OR some routers have an automatic selection
process, that picks the best channel for transmitting signal.

On my router there is a Congestion detection function that checks
determines the channel with the least congestion.

One other thing has one of your other Internet devices changed, or has
one been added. It is possible that one has changed and is sucking up
all of your Internet channel

Have you tried to reset your router. I have ATT uverse and periodically
it bogs down and the router must be reset. When it needs to be reset
one of the symptoms is their is no broadband connection

I don't know about Jason, but I have only one wifie in my house, and
she's been my wifie for almost 60 years.

Yes, there are other WiFi "clients" in the house, but they've ALL
slowed down. Also, my router allows prioritizing devices so they get
preferential treatment. For tests on the laptop, I set it to highest
priority and still see the slowdown. No other device had its
priority boosted.

Doesn't web surfing "performance", depend on DNS ?

It could be the DNS lookup which is slow.
DNS servers are usually arranged in pairs,
and Windows used to have the dismal property
of always checking the devices in the same
order, even if one DNS address isn't actually
working properly. Linux swacks them - a DNS which
fails to respond, is put second in the list, the
working DNS in the pair is first in the list. This
keeps DNS performance high, even if one of the
DNS devices is kaput.

It could be DNS which is slow.

it could be the making of a connection
which is slow (a routing problem).

You can run "tracert www.somedomain.com"
to test the routing. The command stands
for "Trace Route".

You could override the ISP DNS setting (acquired
via DHCP) and set it to 8.8.8.8 (google) or use
the CluodFlare one that they set up. When DNS is
busted in Linux, I slap in 8.8.8.8 to get things
running again. (Without leaving it as a permanent
setting.)

LOL - me too!

I've looked carefully at that potential issue and
don't think it's the (whole) problem. I can watch
the steps in the connection process when I click a link - it's
in the lower-left corner of the Firefox window. Until
recently, all the steps whizzed past. Now, there is a
long-enough-to-be-noticeable delay between each step, which
leads me to believe something's not right with the
performance of "the stack". That's why I tried disabling IPV6.

There's a neat, free utility, DnsJumper, that tests a slew
of resolvers and picks the fastest two. The resolve times
vary, naturally, but the fastest are always in the 10-25ms
range and I'm still seeing that response time even with the
mysterious slowdown.

try this:
http://netalyzr.icsi.berkeley.edu

note that the web version requires java, however, there is an android
native app.

the results should help narrow things down.

Have you tried switching off your modem/router for 20 minutes or so?
They do sometimes get themselves in a twist.

I've seen the same thing with Firefox at times. Of course, I usually have a
half dozen windows open all the time, so that doesn't help. When it starts
to be a problem I just shut down Firefox, then restart it. I know this
doesn't address all your issues, but it is one thing to check.
