[Firmware] Re: Comcast DPC3941T New Firmwire Loaded terminal night

The changes in the firmware may non be compatible with your saved file so information technology may exist all-time to setup everything again then save the new setup as a backup file.

What I ever do with router firmware updates as you lot do not e’er know what was inverse.

Re: [Firmware] Comcast DPC3941T New Firmwire Loaded last night

wonder if this has anything to do with the firmware fix Intel released for the “Puma 6” chipset, of which this gateway is unfortunately infected.

So my DPC3941T looks like it upgraded concluding night as well. I have mine in bridge style, merely now after the update the Wifi lights on the front end of the gateway are flashing constantly. I don’t run across the active Wifi – looks to just be the lights. Anyone else seeing this?

I did exercise a restore and turned span mode on again – no luck, still has the lights flashing.

I also have my gateway in bridge way and it seems similar this firmware no longer disables the wireless network when placed in span mode. It but hides the SSID now.


Interesting. SSID definitely not shown, but I tried manually connecting to the network and it tells me No network found. I also have the Xfinity Home hotspot turned off.

Similar the 3941 the 1682G has had several updates, the lights tin behave differently each time. Recently using the 1682G when setting bridge mode, the wifi lights practice leave initially. If doing a quick reset (non a factory reset) or a powercycle the lights start to wink at i sec intervals…., but the home gateway wireless remains off.
Don’t forget fifty-fifty if the xfinitywifi hotspot is disabled, the hidden Xfinity Abode securiy still broadcasts on 2.4
On the 1682G there are two other subconscious SSID’s on two.iv and 5 could also be for Xfinity Home securty….Just who knows?

computerman2


I talked with a Comcast tech on the Direct forums and he said in that location was a issues in the latest firmware with the lights. He mentioned having an pick to disable under Wifi. He went into my gateway and disabled the radios for me.

Guessing the new update you talk about might fix that event, as information technology definitely isn’t behaving as it used to.

Lights bug my butt! Looks like they’ve locked out the ability to close off their ssids.

I have the light issues too. Did nobody test this firmware update?

The wifi lights are flashing, and the second telephone lite is active even without anything connected.

Well I know I didn’t test it, suddenly arrived over nighttime one nighttime, and yeah 2d phone light active

Wifi I apply on the device, and so those on for me, normal, but 2nd phone light lighted up with nothing continued–i’d say non normal




to
computerman2


This week I had a technician come out, and he thought it wasn’t normal as well. He called his dispatch, and they admitted the 2d telephone line was a issues, and the ii WIFI lights were standard even he told him fifty-fifty in Bridge manner. So he concluded the call.

We both didn’t concord with dispatch, and he has non seen this before, and he replace the modem. The new modem (ane I accept now) didn’t take the current firmware, so it was working fine, and the next day it went back to the current firmware.

I then try to talk to Tier one back up online twice about to written report a trouble with the firmware. She reassure me that it wasn’t a firmware problem and Comcast cannot roll back the old firmware because were not responsible for firmware the only way to report it is by CISCO, so I ended the chat and she reset the router

Nah, actually with the 1682G I was just able to disable the Xfinity Abode ii.four network. For this device, with subsequent firmware updates this (workaround) has been taken away. The hotspot had and all the same does AFAIK have to be disabled in the account.
I would think that if you want to be gratuitous of Comcast hotspots, buy your own device?

(not quite certain what the big deal is with DPC3941T firmware updates is, it’due south their gear, go used to it) lol.

Actually, this appears to exist a firmware upgrade to permit some of the newer Xfinity XB3 gateways to support Comcast’due south new “Digital Home” platform that they appear at this year’southward CES:

From:
Lookout out, Wi-Fi systems! Comcast is transforming its Xfinity gateway to a smart digital home platform
Comcast’s new deject-based platform will bring ease of use, whole home Wi-Fi coverage and useful features to its broadband customers.


By Dong Ngo, CNET – January 4, 2017
»www.cnet.com/news/ces-20 ··· al-dwelling house/

quote:


… Today at CES 2017 Comcast is demoing an all-new cloud-based platform for digital home that’s slated to make life better for some 10 million customers that are currently using the broadband Xfinity gateways.

On the surface, this is Comcast’s endeavour to transform the existing gateways into a smarter a Wi-Fi solution to address the ascent in popularity of absurd solutions similar the Google Wifi, the Eero or the Starry. Deep down, still, this shows the company’s ambition to dominate the Wi-Fi system market. …
:
:
The new platform volition be pushed to all existing supported gateways — namely the Arris 1682G, the
Cisco 3941T, and the Cisco 3939 —
in the first quarter of 2017
at no cost to the consumers. … And then if you don’t listen using Comcast equipment, this will be by far the biggest and coolest update, comparable to getting yourself the all-time Wi-Fi system. Because the large number of customers who use Comcast gateways — which Comcast expect to increment to 15 million by the end of 2017 …

Also in bridged mode, and I’ve the aforementioned model and all (information technology’s on DPC3941_2.3p16s1_PROD_sey), same effect (wifi lights blinking), for at present it’s electric tape to the rescue for the lights. Using some wifi tools information technology does non seem to be connectable, but if you go into troubleshooting tab and utilise the spectrum you can see the radios are active.

They likewise seemed to have cleaved the logd for me, and the advanced tab leads to a new page called dynamic_dns.php which has access denied when attempting to utilise it, the hardware info page is also kind of borked.

Nice update.

Exercise take a battery installed

Gateway > Hardware > LAN Ethernet
LAN Ethernet Port 2 = Active
Just, null is connected.

System Logs appears to not exist working.

Yeah, there’due south a thread on reddit near it, a comcast employee claims the following, and I quote:

“We were updating the DPC3941T with RDK so that could exist what the update was. I believe it was last calendar week when we had a big push to get those completed.”

So information technology just looks like the big wigs wanted it out the door to endeavor and stay consistent with the announcement whether it was prepare or not.

It’s Comcastic!
