Arris TG3482 Strange Issue-DOA?

We have had the new gateway since Wednesday. Everything was operating normally until last night/this morning.
I have one wired connection-desktop Win 10 64bit with Cat5e cable the tech used for install.
Starting last night, as soon as I power up the desktop the gateway goes in to countious reboot.
When I shut down the PC, the gateway returns to normal.
Any suggestions other than replace device? I'm thinking it's DOA, tried another device and different ethernet cord and get same result.

The only thing I can think of is to try a completely different device with the PC unplugged and turned off.

Just for giggles, have you tried connecting the computer to a different ethernet port ? How about a different cable ? Have your powercycled the gateway ? Have you tried resettng it back to factory defaults ? Still no joy ? Get it swapped for another.

A reset back to factory defaults on the gateway seems to have cleared it up.

Thanks!

Re: Arris TG3482 Strange Issue-DOA?

Well, strange enough it started happening again.

Just for grins I checked my adapter configuration.

Only thing "out of the norm" was Jumbo Packets.  They were set to max (9014 bytes), I put it back down to 1514 bytes and, for now, the issue has cleared again.

Any idea what jumbo packet allowance would have to do with the Gateway?  I don't even remember adjusting the jumbo packets, and I know the other two devices I plugged in to the gateway are not set to 9014 bytes (because their NIC's do not have that option to adjust).
I will keep on eye on it and report if the issue resurfaces.

Thanks for the feedback. Jumbo packet support can be challenging for sure. Can you tell us what firmware your running on your cable modem?

1. Go to 10.0.0.1
2. Log into the modem via the following creds (unless you changed them)

Username: admin
Password: password

Note: admin is lower case

2. In the modem go to Software and tell us if your using x.206 or x.208 or something else.

Some folks have complained about putting the modem into Bridging Mode which basically turns off the Wifi and other networking abilities so that you can use a 3rd party AC router but like myself was seeing random reboots.

I have x.206 and even with a reset it was rebooting so going to check the Jumbo settings on my Network cards.

Thanks,

Curt
