Google fibre network notes
I struggled for two weeks and 4 support engineers to get port-forwarding set up.
This is becuase I had too much respect for them to do stuff behind their back.
I did take the leap of performing a software reset of the router; this accomplished
nothing. Finally, I told the last one that I'd like to do a hard-reset of the
router before giving up and returning to Comcast. He told me "Yes, I usually
recommend using the red reset button on the device. Hold it down for 10 seconds."
Really? Given that I explained the problem and jumped through the same hoops under
the auspices of 4 engineers, none of the reached the conclusion that a hard reset
would be the answer until I suggested it myself?
I had not done this because I feared it would destroy whatever they set up in
the firmware when the original installer came out, and because they hadn't told
me to do it, I figured I shouldn't go around them. So much for blind respect!
Plex Media server hiccup 8 July 2015
I experienced a Plex Media server-down event, perhaps as early as the evening of 6 July. It's
difficult to tell because we consume from inside the LAN, so unless the server hardware or software
is down, we're up. However, those outside may lose connection because of Google Fibre's Network
Box. It's hard to diagnose or know unless I'm outside, but then I can't fix it.
I've put the Plex application on my phone, but when I connect inside the house, it decides to go
through wireless, which again, puts me on the LAN. Then what I do is kill my phone's wireless
connection forcing it to use the phone's data services. That way I know whether it's really up or
In my case right now, it's down.
Always revising instructions to get into Network Box...
Because Google keeps changing how this works.
To get to customer support, use this link:
Log in using your Google password, the same one you use to do mail.
Look for Customer Support, call, chat or email us and click.
However, to get to Network Box, do this:
Click the Network tab at page's top,
Network Box Settings, click Network Box Advanced Interface → Enabled
The box expands, copy the password presented and click
Go to Network Box Advanced
Log in; the
User name is "admin" and you replace the dots in Password with
what you just copied.
At this point, you can refer to the section entitled, "Soft-reset, but entirely rethought on
26 May 2015."
Resetting Google's Network Box
At this point, everything looks okay, but Plex isn't on-line. So what can I do, but reset?
Go to the
System tab. Click the
Maintenance subtab. Click
OK to the question, "Are you sure you want to reboot GFRG?"
This is a soft reset; it shouldn't change my configurations as taking a paper clip to back of the
Network Box itself would.
tol-eressea is still off-line for Plex according to my cell phone (whereas two others
I'm subscribed to are available). I'm going to have to think of something else.
Seen from inside LAN as

Maybe this is on Plex' end. The problem is that I don't have anyone standing by to verify that what
I see from my phone, which I have been counting on to diagnose this problem. I went to Plex in my

Here I found a red-circled checkmark, which I investigated. It seems I need to authenticate, which
I did. Then it changed to a green checkmark. I rechecked my phone and I have access. This can't be
the solution to anyone but me.
So, I'm left wondering...
Why Helene was complaining about access last Monday evening?
Why, from work, I could not reach my Plex Media server via browser today?
Soft-reset, but entirely rethought on 26 May 2015
This will be the last time, I hope. Today, Jacob showed me that he had found a way to turn the
Google Network Box into nothing more than a modem allowing me to use my own router. I've been using
my own router all along. Jacob came across this solution last fall by trial and error: you cannot
"Google" and find it, it's not in any documents and Google support isn't going to tell you how to
What creates this problem is that Google Fiber is simply in beta, in three cities, with beta
hardware like the Network Box, and a beta organization. So Google doesn't have the system baked yet
and their support engineers don't have the bandwidth to work with other than mundane customer who
aren't trying to do what I am doing (serve up webpages, Plex Media,
ssh into home, etc.).
One problem of instability has been how I've been doing the port-forwarding. Google support had me
forwarding, as shown in snapshots elsewhere on this page, but more or less reproduced here:
HTTP - TCP Any → 80
SSH - TCP Any → 22
Plex - TCP Any → 32400
This had the result of forwarding
everything over TCP to ports 80, 22 and 32400 letting the
router sort it all out. Yeah, but that's what Google support told me to do.
What we did this time...
Go into the Network Box, there's an easier way, just go to
Home (tab) Network Overview.
Ensure that the TP-LINK router is the
only device connected to Google Network Box. You
should see something like this:

Here we go again. And have I said that in 20 years of subscribing to various ISPs
I have never had the incessant troubles that I have with Google? And, they've
changed the port-forwarding interface again, making it even harder to use because
more obscure. They don't let you name the forwarded port any more, so I can't label
it "ssh" and "Plex Media server."
Use the steps

While getting in, Google will reset the Network Box as a result of that

to be when Google updates the software on the Network Box and that's how you
get a worse and worse interface.

Instead, click on Overview, then squint for the name, which most of
the time won't be a real hostname, but you'll have to screw around in this
maze of interfaces to infer what Google thinks your computer's name is.
Once you've found that, look for Physical Address under the list
you get by clicking IP Address Distribution.
This is nasty, but what can you do?

In the end, all we did was port-forwarding. Click on that on this page:

ports 80, 22 and 32400 forwarded. HTTP works. The other two do not.
Setting up static IP address assignment?
Go back to having my own internal router
The idea is to recreate the succesful environment I had with Comcast which
consisted of their cable modem and my own router to manage the network.
So after two weeks, I gave up and bought a TP-LINK Gigabit Router that was
pretty easy to configure. However, it really appears that Google's Network Box
just won't let go. A good hour on a chat with a Google support engineer did not
help either although I think I got some good advice like how to configure
the port-forwarding of a user-defined port (32400 for my Plex Media server).
The Google support guy insisted that I had to open the same holes through
Google's Network Box as I wanted to reach the TP-LINK router. I told him I
just wanted Network Box completely out of the way, but I did set up the
port-forwarding he asked for. At his request, I sent screenshots for him
Here are some illustrations:
Ditto, another view...

the Google support guy told me that was new.
After continuing to play with the network all that afternoon and
evening I conceded defeat and made the preliminary determination
to return to Comcast.
State of things...
Internally, everything works identically to pre-Google fiber. All the
hosts I wanted to have static IP addresses have them. My web and
Plex Media server still functions perfectly in-house, but is invisible
outside. Static IP addresses and forwarded ports on the TP-LINK:
The 1 January 2015 outage...
During the night of 31 December to 1 January there was a power outage. Clocks
that were still running said about 2 minutes slower than actual time, so we
figured power was out for that long. We reset the clocks, but didn't check into
the WAN. We used Plex Media all day, but from inside the house (over the LAN).
Later, my father notified me that he couldn't get into his web pages. When I
got around to checking things out, I discovered that we were back in the same
situation as a month ago: no port-forwarding was working. The Network Box
It was too late for me to want to stay up to fix it. So I looked into it once
