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

computerman2 Premium Member bring together:2002-04-20 Trenton, MI	so far only copied the wifi passwords, most restored saved file, but decided didn’t really need to

train_wreck slow this bird down join:2013-x-04 Antioch, TN	to computerman2 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.

computerman2 Premium Fellow member join:2002-04-20 Trenton, MI	What I was wondering to, but not sure yet, as too early to make a judgement with the games if its running meliorate than it previously did…nonetheless checking things out

train_wreck boring this bird downward bring together:2013-10-04 Antioch, TN	maybe utilize this site’s checker tool

computerman2 Premium Fellow member join:2002-04-20 Trenton, MI	yes tin exercise that when I don’t accept the other game running, and hopefully have good results

train_wreck slow this bird down join:2013-x-04 Antioch, TN	I also wonder (merely pretty much know the answer): when will this make it to the business class variant, the DPC3941B

	side by side up is the 1682g hopefully

	to computerman2 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. Cablevision Modem HW Version:1.0 Vendor:Scientific-Atlanta, Inc.

	said past netnothing: And so my DPC3941T looks like it upgraded last nighttime as well.

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. -Kevin

computerman2 Premium Member join:2002-04-twenty Trenton, MI	Study in Offical Xfinity Forums on a 2d update for DPC 3941T models, version 2.3p15s2_PROD_sey, no changelog or annihilation on information technology, aforementioned for ane noticed yesterday though

Soups join:2015-10-fifteen USA	Soups Member 2017-Mar-11 12:04 am 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?


	to 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. -Kevin

VONF join:2015-10-22 usa	to Soups I was originally able to log into my xfinity gateway and disable the public xfinity wfi but no anymore. Does anyone accept updates to these … thank you. disabling xfinity hotspot: x.0.0.one/wireless_network_configuration_edit_public.php?id=5 10.0.0.1/wireless_network_configuration_edit_public.php?id=half-dozen disabling xfinity abode: 10.0.0.one/wireless_network_configuration_edit.php?id=3

	I always turned the public hotspot off via the Xfinity app on iOS on via my account online: »client.xfinity.com/#/south ··· internet -Kevin

Samir bring together:2010-02-06 Madison, AL	to VONF Lights bug my butt! Looks like they’ve locked out the ability to close off their ssids.

	to computerman2 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.

computerman2 Premium Member join:2002-04-20 Trenton, MI	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

Soups join:2015-ten-15 Usa to VONF 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.

johnnn bring together:2007-01-25 Ann Arbor, MI	to computerman2 We got a new firmware load on the DPC3941B to dpc3941b-v303r20421746-170221a-CMCST back on iii/14.

delta4 join:2001-04-30 Maple Shade, NJ	to computerman2 Got DPC3941_2.3p16s1_PROD_sey in NJ this morning.

computerman2 Premium Member join:2002-04-20 Trenton, MI	Gonna have to reboot mine over again and see if I become the ii.3p16s1 in the morning, got 2.3p14 I think right now, was when I looked before

	to delta4 Got this firmware as well. No alter in the WiFi lights while in bridge mode. -Kevin

damaged ipv6, just the doc says I’ll be fine. bring together:2000-12-25 Hallandale, FL ARRIS BGW210-700 (Software) pfSense to netnothing 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.

damaged ipv6, but the doctor says I’ll exist fine. join:2000-12-25 Hallandale, FL ARRIS BGW210-700 (Software) pfSense	damaged Member 2017-Mar-29 ten:36 am 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!
