Can't log into Xfinity Gateway

[Boris]

My Xfinity Gateway (CommScope TG4482) is leased. I got it about two years
ago and just plugged it in and it worked. I don't remember ever
resetting/changing my gateway's SSID or password that's on the label on the
bottom of the gateway.  Going to 10.0.0.1 and entering the default "admin"
and "password" doesn't work.  Entering the SSID and password on the label
doesn't work.

I have the manual for the gateway, and have consulted Xfinity support and
articles.

I don't want to change anything, since it's working fine. I have a wifi
network working fine. I just got curious and want to log into the gateway,
but can't.

Any ideas?

If you have a wi-fi password for you pc's or smart home, then you had to (or should have) gone in
and changed it. If you have a dvr from xfinity, I think you can find some info via the settings
menu. Same about logging in on the web. I was surprised how much was visible to you.
Not sure if the router password is visible. A paperclip in the back of the router WILL reset it to
the settings on the label.

I just got a new router a few months ago (had a defective unit). When the tech put it in, he went
on his tablet and did something in 2 keystrokes and bingo, all the passwords/SSID/wi-fi etc were
reset to what I had on the other router. Not sure if you could get support to tell you all that
info?

I do have a wifi password for the pcs here. I did set that up long ago,
when got the gateway, but for the life of me, I just don't remember
setting or configuring anything on the gateway. I'm with you, as to how
in the world can I set up wifi on the router portion of a gateway without
logging into the new gateway. I'm obsessive about writing everything
down when I set up or configure any device, or install new software, but
I don't have any notes on setting up this gateway.

There is a dvr in the system, but no id/pw info.

This gateway does not have a reset 'hole'. There is a button on the rear
of the device, which the manual says if for WPS. However, I do see that
VanguardLH suggests (thank you for your reply, VanguardLH) it could be
used to reset the gateway, depending on how long one holds the button in.
I have found instructions that say a 60 second hold will reset the
gateway.

I haven't tried the 60 second hold because as VanguardLH has said, it
sometimes takes 20 minutes or more for the gateway to come back online,
and then I'd have to re-configure. Since everything is working fine,
family members here would not be happy to loose connection for as long as
it may take to get things going again, just because I was curious as to
why I can't log into the gateway.

There is probably a small hole on the backside in which you push an
unbent paper clip to push on a button inside. Hold the switch down for
less than 3 seconds; else, a longer push resets the modem which requires
reprovisioning it (the ISP pushes the parameters per your account with
them, like how many channels to bind for the bandwidth provided with
your service tier with them). A short press is a restart. A long press
is a reset.

Hmm, guess that model does not use a momentary switch for
restart/refresh. Instead you press and hold the WPS button. No mention
of a restart, just a reset. A reset puts the device back to its
defaults which should use the SSIDs printed on its label, but could also
mean you have to reprovision the modem. Holding longer than 10 seconds
does a reset, although I've seen instructions to say hold for 30.

Used to be you just called the ISP's tech support to ask them to
reprovision the modem. Now they want you using their phone app.

"admin" and "password" are typical default login credentials to the
modem's internal web server, but not always. If those are the defaults,
a reset should restore them.

Did you ever configure the modem to grant external access to its config
(internal web server)? If so, could be someone other than you (i.e.,
hacker) changes the login credentials. I believe they are also case
sensitive (all lowercase). Anyone else in your household have physical
access to the modem, or you share the modem, but didn't bother to
immediately change the login credentials to prevent tampering (like
changing the password since the "admin" username is often fixed)?

If you, or someone else, changed the SSIDs (they can be changed using
the internal web server), or the login credentials, those are what need
to be used now until you reset to the defaults. "admin" and "password"
are the typical defaults, but the defaults could be different, so check
what the label says. Those are likely the defaults that get used after
resetting the modem.

The SSIDs (2.4 and 5 GHz) are what wifi devices use to connect to the
modem. They identify your modem's wifi radios. Passwords are used
along with SSIDs to ensure only your devices connect to the modem.
SSIDs are not used to log into its internal web server.

I don't trust the firmware to decide when I've overstayed my welcome on
the WPS button and proceeds to reset the modem. The safest way to
restart the modem is to pull either the ac plug out of the wall or pull
the AC power adapter's plug out of the back of the gateway. In either
case, wait at least 30 seconds and plug back in. The gateway will
restart with no risk of accidentally resetting it. Another way to
restart the modem is if you have either an iphone or an android phone,
download and install the zfinity app and log in with your xfinity
credentials. You can restart the modem from within that app. Third way
is to use your web browser to log into your xfinity account and do it
from there as well. Fourth way is if you have a wired xfinity voice
phone number, call the xfinity customer service number and tell the bot
you're having a problem with internet. The bot will tell you that they
have to restart the gateway to do diagnostics and that the restart may
solve your problem. Give the bot permission to restart your gateway.

Make sure you don't have a model of modem that includes a battery
backup. I had one a couple years back. Unplugging the modem meant I
would have to wait around about 20 minutes, or longer, to let the
battery drain, or open the access panel to remove the battery (it slid
in and out). Same if you put the modem on a UPS. The reset function in
the modem doesn't need to wait to lose line power.

Waiting for capacitors to drain, or batteries, or UPSes, or unplugging
and replugging the A/C cord (which can be a hassle unless the modem
isn't buried under a desk), a restart happens immediate after pressing
and releasing the reset button. Pressing and holding longer than 10
seconds to reset is probably less time than the other methods.

Despite how long each method takes, the longest time you wait is for the
damn modem to boot again. I think mine takes at least 20 minutes before
it is again ready for use.
