CGN3 - Sporadic random disconnect/reconnects

Leakyfaucet
I'm Here A Lot

Recently had the internet in the place I'm renting upgraded and I seem to have this issue quite often. I will randomly disconnect from Mumble and the loading of webpages will stop for a bit, but I will stay connected on World of Warcraft. It happens for a few seconds and then it reconnects. The timing is fairly random, and it SOMETIMES disconnects me from WoW at the same time but never both Mumble and WoW at the same time. 

The mumble disconnect happens every 20minutes to an hour, some times it wont happen for long periods. WoW one happens entirely randomly not sure if they're related at all.

 

The issue I have is I'm renting a place with people and am NOT able to mess with the hardware configurations, that is to say, I can't do bridged mode and use another router. I can only go in and change some settings, without disabling wireless bands. I can use a router/switch inbetween my wired connection and the modem.

 

Not sure where to go from here, troubleshooting has led me nowhere. 

So far I've:
- Tried Google DNS

- Tried OPENDNS

- Firewall is off on PC

- Tried using direct IPs for mumble. 

- Using Static IP instead of Lease

- Used laptop Wireless connected to mumble, still has same issues BUT we dont always disconnect at the same time(s).

 

Any ideas on pinpointing and/or fixing the issue?

Thanks

Ok we're in the same boat here kind of re-mumble situation.  Infact I'm postive we're both having the exact same issue, web page slowdown, the mumble crashes, but still on in the game.

 

Doing reading all night and just seems the Routing funcationality in CGN3 is just...

 

Atleast I have the option to pop my old router down which i did but dropped me from 250mbps down to 30mbps, it's a new 10/100 router i bought a month ago before realizing rogers went wide with the Hybrid system months back.  ( I should have kept up with the upgrade i would have spent the extra 10$ for gigbit ports).

 

 I feel i have no choice but to buy another router... btw the disconnects in mumble etc stopped when i went bridged.

 

Absolutely no way you can plop a router down and have everyone connect to it?  If you try to plop it down as well without bridging the CGN you're gonna end up double NATing.

Has most of this, been happening on wired or wireless?

If wired.. there may not be much that can be done, with not having access to do anything more at the modem level.

About the ONLY thing you could try i would think.. would be if you have a wired connection available.. to get your own router.. and run as an ACCESS point.. so you  are doing your connections through it instead, especially for wireless.

Re: CGN3 - Sporadic random disconnect/reconnects

This has been happening wired, However I AM useing a powerline ethernet system, not sure if that's what's causing issues but I don't think so.

 

So you're saying have the modem the way it is now, and run another one on say 192.168.1.xxx hardwire that to the modem and use that instead? 

Also not sure if it means anything but the modem doesnt show anything for Clients when I was using DHCP

Re: CGN3 - Sporadic random disconnect/reconnects

Can you tell us what modem is in use?  As well, where is the mumble server located, in the U.S. or Canada.  I'm wondering if you're running into issues with servers somewhere down in the U.S. causing problems.  There is one thing you could check and that is what side of the electrical panel both wireline devices are on, right or left.  If they don't sit on the same side, see if you could move one of them to a location where it will be on the same side.  Then run whatever length of ethernet cable you need to make that work, either into the first device or from the second device.  That probably isn't how it can be left permanently, but just for test purposes see if that makes any difference.  One other thing you can check is the cable signal.  Here's a link to my CGN3 DOCSIS WAN data showing the downstream and upstream power levels and signal to noise ratios.

Can you log into your modem, navigate to the DOCSIS WAN page, copy those table and paste them into this thread, just for a quick check that will hopefully rule out any cable issues.  Copy the tables only, and none of the other data that sits above the downstream table such as the WAN IP Address and others.



Re: CGN3 - Sporadic random disconnect/reconnects

Thats possible as well datalink.. could be one of the major  peering partners... as that has effected many things recently.

 

Though i wouldnt discount suff localy... especially now that he has mentioned POWERLINE adapters.
I have heard mixed things about them... both on the same breaker? not bad.. outlets on seperate breakers?... and just even distance.. and the wiring quality, etc... can make them VERY flakey.

 

I would see if you are allowed to do some TESTING, running a long ethernet just temp to somewhere.. and seeing if you get the same results.

Re: CGN3 - Sporadic random disconnect/reconnects

I wasn't actually thinking about putting them on the same breaker, although for test purposes that isn't a bad idea at all.  I just wanted to see what would happen if both powerline devices were on the same side of the panel, as they would then connect via their respective breakers and the same hot and neutral/ground bus bars within the panel.



Re: CGN3 - Sporadic random disconnect/reconnects

I'd have to test the same side on monday or something after I get a bit longer wire.
Mumble server is in Chicago.

I've been having a similar issue...

 

Just got the new CGN today after upgrading from the old extreme package..

 

my mumble has been randomly disconnecting all day... on top that i find that when for example i try to connect to a Dayz server (its a game) my Mumble will disconnect 80% of the time and rejoin in 5 seconds.

 

Now this didn't happen when i was on extreme, and i can't for the life of me figure it out.

 

Im wired, so its not QoS.

Re: CGN3 - Sporadic random disconnect/reconnects

Since you just picked up the CGN3 today, have a look at the following post which summarizes the present situation with the CGN3 (I'm assuming CGN3 here);

 

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Getting_connected/message-id/190...

 

There are latency issues with the CGN3 and I'm wondering if that is coming into play here given your comment on the fact that it didn't happen when you were on a different router, 3825 by chance?  I wonder if the only way to solve it, until the next firmware release is to run the CGN3 in Bridge mode and use your own router to do everything such as firewall, port forwarding, wired and wireless support etc, etc.  If anyone is using a CGN3 in Bridge mode with a 3rd party modem behind it, and using Mumble, please chime in here and indicate if Mumble works, or if it still has issues.

 

Can you check your firmware version by logging into the CGN3?  The latest firmware version is 4.2.4.3.  If you have 4.1.4.1, it will take about 4 to 5 days for Rogers to push the next version out to your CGN3.

 

 

 

 



Re: CGN3 - Sporadic random disconnect/reconnects

I'm on 4.2.4.3. Would it make a difference if I used a switch or router without doing the bridge mode? I can't bridge since everyone else is using the WiFi on it already.

Re: CGN3 - Sporadic random disconnect/reconnects

Thats very interesting to say the least.  It really confirms that the trouble that many people are having when gaming is a problem with the CGN3.  You don't have to double NAT however.  You can turn off the DHCP on the router and use it as an access point.  The CGN3 will then determine the LAN IP address for everything connecting through the router.  Any chance you could still return the router for one that has gigabit ports?  Never know till you try.



Re: CGN3 - Sporadic random disconnect/reconnects

@Leakyfaucet, looks like your in the same boat. I would think that the only way to solve this is to put the CGN3 in Bridge mode and connect a router to it, and let it handle everything, wired and wireless.  In that configuration there wouldn't be any difference to the downstream devices as they wouldn't know or care if they were connected to a CGN3 or another router, but you would see better performance when running a 3rd party router.

 

Edit:  Here's a thought for both of you.  The Mumble application may be running some type of constant comm check in the background which is dependant on the return timing.  Don't make the window and you are dropped off the server. I wonder if there is a setting to adjust that timing window within the application that would keep the application and server satisfied enough to keep running?  We're probably talking no more than a few milliseconds difference to keep the application running properly.

It doesn't seem that the issue is limited to CGN3 modems.

 

I have the older SMC3DGN and I've been experiencing random disconnects across all devices (wired and wireless) over the last couple of days. The issue seems to be the same as yours. Sometimes the service drops after 20-30 minutes, and sometimes it stays up for almost 2 hours, but none the less, a disconnect does occur at some point. 

 

I've been trying to play Destiny on the PS4 which is hardwired to the modem, and being kicked mid-match has been very annoying.

 

Re: CGN3 - Sporadic random disconnect/reconnects

wondering the location of any of the people with the issue.. seeing if its a specific region, etc.

The other night, played wow for about 4 hours, while downloading.. with not as much as a hickup.

Downtown Toronto (Church and Queen area)

 

Anybody else around the same place?

 

A few people at work are also experiencing issues, and they're mostly in Markham.

+1 re: the disconnects over the past few days  I don't have the CGN3 but the Cisco modem.  I think it was Tuesday or Wednesday when it first started with an internet outage that lasted an hour or so.  Since then, I've noticed more frequent drop outs than normal.  They don't last long but it's annoying.

Re: CGN3 - Sporadic random disconnect/reconnects

Scarborough for me, Military and Ellesmare. 

 

I have a Gigabit switch (GXD1081) Setup as such:
Modem -> Switch -> Powerline -> PC. (All CAT5e)

Still having the disconnects. Happened almost 10 minutes in of switching it. 

What is the downside to double NAT? I dont have the money atm to get another Dualband router and switch it up for everyone, especially since the issue isnt exactly the worst thing, it's just annoying. 

Re: CGN3 - Sporadic random disconnect/reconnects

For regular browsing, etc? Not much.. might be a tiny bit slower, as it has to do the 2nd taverse/nat for a split second.

But for some other stuff... gaming, etc.. which relys HEAVILY on going through the NAT (and has issues as it is with some of the newer routers).. double NATing would be suicide.

Re: CGN3 - Sporadic random disconnect/reconnects

I didn't really know that. Back at my home I used to use (about a year back) double NAT all the time. I had the modem setup on 192.168.0.1, and the router was setup as 192.168.1.1 and I had most of the house network on the router. 

Guess I'll just have to live with it in the hopes theres some sort of firmware upgrade that gets pushed out to resolve the issue.

On modem number 4 at the moment. This has to be the worst modem I've ever used. Rogers, you call this acceptable? 4 modems in a month all with the same issue, they randomly disconnect every few hours. Not sure what to do at this point. Anyone else having issues with this sorry excuse for a modem?
