Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

I recently upgraded to the hybrid fibre 60 plan and picked up the new advanced gateway. Ever since then I've been having issues with upstream speed stability. I first noticed it when I tried to watch my slingbox while on my lunch break and at first the bit rate was high and climbing but it wouldn't last more than 40s before it came crashing down and the video would just lag like crazy. But then it would pick back up, and then down again. Sometimes it would actually disconnect. I've also noticed this when trying to play online with my PS3. For a while all is good and I'm killing and baddies and then lag like crazy, next thing I know I'm being booted from the game.

 

Does anyone else have this issue? Is there anything to fix it? Rogers tech support wasn't very helpful, all I was told was that my devices weren't setup properly which isn't possible as I've gone through everything, even multiple configurations of wired vs wireless. Definitely not an issue within my network, only when it goes out over the internet.

 

Any insights are appreciated.

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

Some people have noticed that there is a slightly higher pings with the CGN3... anywhere from 1ms to like 20some odd.. potentially higher than they should be.. but shouldnt be anything that effect streaming in the degree you are explaining.

 

There are two things i am possibly thinking here.

 

A ) how is the slingbox connected?  And if its wired.. what is the speed port on it? 10/100 or gigabit?

B ) Your signal levels... could be a bit off.  Are you able to post your signal levels from the modem?

 

I am on the hybrid 60 package, and dont have an issue connecting to my plex server remotetly and streaming.

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

I have my slingbox connected through my wireless bridge which is connected to the CGN3 on the 5Ghz band. I know it has nothing to do with that connection though because I'm able to stream within the LAN to my main PC which is wired directly to the CGN3 without any issues. It's only when it goes outside of the LAN where it does that up and down crap. Tried on my cell through wifi connection (LAN) and no issues, switch to cell data and then it happens. Tried on my laptop at work through the web interface and it also does the same thing. And the thing is, this all worked just fine with my old cisco modem on the old plan.

 

Are these the signal levels you're referring to?

Your Signal Power levels and Signal to Noise ratios are fine.  The upstream Signal Power levels are slightly high but they shouldn't cause problems.  Here they are in a slightly different format.

Ping times and latency with the CGN3 are an issue.  A possible solution is to run the CGN3 in bridge mode and use a third party router for any and all router duties.  I'm still waiting for someone to run a ping test to the CGN3, through the router to prove without a doubt that this does resolve latency issues with the CGN3.   If you read through many of the threads here you will see that this is an ongoing issue, but to be fair, if you read through other forums you will see that latency is also an issue with other ISPs.

 

Just to check, did you use the USB Setup Drive to setup the CGN3, including a guest network?  If so, I will possibly have instructions to follow to check the CGN3 wireless network transmissions.

 

Here is a link to a thread page containing a summery that I did not too long ago regarding the CGN3:

You're looking for someone to ping something on the other end of a bridged CGN3 from outside Rogers?

 

I can ping from a VPS to my router on the other end of a bridged CGN3 if you want. How many pings?

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

Nope, looking for someone to follow dcowan38's instructions to determine the CNG3 address when its running in Bridge mode, and, with that address and a typical Bridge mode CGN3 connected to a router, connected to a pc or laptop, ping the CGN3 from the pc or laptop, through the router to the CGN3.  The question at hand is, does Bridge mode really make a difference in terms of ping times to the CGN3.  Just trying to see if there is any facts that back up that idea.  Dcowan38's instructions are found in post #12 in this thread:

 

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Getting_connected/message-id/180...

 

Here's a sample of a ping test to my CGN3 in Gateway mode, single wired pc, wireless turned off, no applications running on the pc.

Ping statistics for 10.0.0.1:
    Packets: Sent = 1000, Received = 1000, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 60ms, Average = 5ms

 

So, where I've seen consistent 1 ms or less ping times from other posts of other modems, my CGN3 usually averages out at 4 or 5 ms, with occasional rare excursions up to 60 ms in this case, and with ping times that are not consistent, ping to ping.  Rerunning the ping test on another wired pc, the result is the same, 5 ms average after 1000 pings, again, with rare high ping times and inconsistent ping times.    Although the average times are low, they are still part of the latency problem.  The question is, "Does Bridge mode really reduce latency to and from the CGN3?" Only one way to determine that, ping the CGN3 while its operating in Bridge mode.

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

But in non bridged...even with those small bits of latency.. that shouldnt really effect it THAT much.

My setup.. i have the CGN3, non bridged.. cat5e cable (prob 75 ft?) over to a home grade gigabit 8 port dlink switch, then a cat5e down to my server PC with a gigabit card in it.

Pinging from that server.. get similar results  anywhere between 1-10ms responses.. bouncing around a bit.

I regularily stream from home, from my PLEX media server, either through the web interface at work, or from my mobile app (usually on wifi at work)

I dont have a single issue with it streaming.  Though, i do have the media servers settings, set to push a MAX of 4mbps on the up stream.
Perhaps that may be part of the issue.. the slingbox is trying to push a higher stream than it can provide?

 

Though.. all in all.. my FIRST thought from the description of what the setup is?
Something between the wireless bridge, etc is causing it.  More than likely the connection between the bridge and the wireless on the CGN3.
To fully test.. i would

A ) Try it with the slingbox directly connected to the CGN3.. see if the same issues occur.
B ) If they are not present above.. again comes down to the wireless bridge, or at least its connection to the CGN3.  This is a case where bridge mode, or at least a 3rd party router, as an AP, would likely be of benifit.

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

I'll give it a try when I get home but I don't think it has anything to do with my wireless bridge connection to the CGN3. The reason I say that is because I have a PC with a wired connection to the CGN3 and when I watch my slingbox on that PC I don't experience the upstream fluctuation, its as steady as can be with a bit rate around 8000kbps.

 

If it does have something to do with the CGN3 being used in gateway mode then I'm going to be a little angry because one of the reasons I got the CGN3 was because of its dual band wi-fi capabilities at 450Mbps, so I ditched my old bridge which only went up to 150Mbps and replaced with the router that I was using in conjunction with my old cisco modem. (I installed dd-wrt on the router to make it an AP\Bridge so I can get 450Mbps speeds over the wireless bridge connection). As far as I can tell everything with in the LAN works fine. It's only seems to be an issue when it goes out to the net.

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

does the slingbox have different settings when its going external? (i know my plex does).

 

While it is dual band.. the wireless is still not great overall on the CNG3 (better than the others.. but still not great).
My previous router of a 10/100 port Linksys E2500 dual band had better range.

Your BEST overall solution is to bridge the CGN3 as well then.

(there are other advantages to the CGN3 though as well, with the 24 channel capability, etc.)

Re: Upgraded to Hybrid Fibre 60 and CGN3 and now I can't stream slingbox

The only other configuration it needs for externalizing it is adding the port forwarding info to the router, which I have done, and since I can actually connect to the slingbox over the net I'm sure that's not an issue or I wouldn't be able to connect at all.

 

I think as a last ditch effort I'm going to get them to swap out the modem for another one and try it. If that still doesn't work and bridge mode is the only way to go then I'd rather get the DOCSIS 3 Cisco modem which is a few bucks cheaper to rent and do the 3rd party router setup that way.

 

I'll reply back to this chain once I've done a little more tinkering.
