Slow Streaming - post fast.com speeds

techtrader
I'm Here A Lot

I have the 100/10 package with the AC modem connected to an RT68 in bridged mode.

 

My internet has been unstable streaming content for the past several weeks with lots of buffering. Was fine before this.

 

Speedtest.com results are genreally good, downstream varies from 50-110 Mbps; upload always hits 10 Mbps.

 

Fast.com is sometimes under 1Mbps  (5Mbps now) and streaming 1080p clips from Youtube results in really choppy playback .

 

Support is investigating and its been a few days. 

 

What are your fast.com speeds ?

Re: Slow Streaming - post fast.com speeds

I've seen a speedtest with fast.com run as high as 590 Mb/s, but, the next might be down to 200 Mb/s.  The results with fast.com are very inconsistent, to the point that I would disregard them.  If you want to run a speedtest and see consistent results use the Rogers speedtest, http://speedcheck.rogers.com/en.html or use speedtest.net Toronto Telus server first, Toronto Beanfield server second.  

 

Just so I have this correct, you have a CGN3SMR (?) running in Bridge mode connected to an Asus RT-AC68U(?) ?

 

And you connect a laptop or smart tv to the RT-AC68U(?) via wifi?

 

Connecting via 2.4 Ghz, 5 Ghz n network or 5 Ghz 802.11ac network?  If you are using a 5 Ghz network you should be using channel 149 or higher as the those channels have a higher allowable power output. 

 

You indicated that this is a new home.  Are you using a short commercially produced cable to connect the router to the modem, or using the house ethernet with modem in one location and the router somewhere else in the house?

 

Here is some food for thought, load inSSIDer on your laptop and grab an image of the network display and post it.  inSSIDer will monitor both 2.4 and 5 Ghz networks that can be detected by your laptop. The program link below is for the last freebie version. It doesn't process or show the 802.11ac network running in the 5 Ghz band so it doesn't present a complete 5 Ghz picture.  A new version is out now that will handle 802.11ac networks, and which will work on a 802.11n laptop. The new version will read the broadcast management frames and display the 802.11ac networks that are running in the 5 Ghz band. It worth the $20 U.S. to buy, so that you can see all of the networks that are nearby.

Hi @techtrader

 

Welcome to  the Community Forums! Smiley Happy

 

Is this on WiFi or on a direct connection that you're experiencing the issue?

 

One of Resident Experts can provide further insight, @Datalink or @Gdkitty ?

Your signal strength is not horrible. Not sure it would be that.

As asked is this on wired or wireless in your house?
Is it a house or apartment.

Fast.com is not a worthwhile source to overall test your speed.
Fast.com is a site set up my Netflix.
It really is a speed test to their servers.
(Which is Good for testing your Netflix speeds tho)
But any ISP like Rogers who is part of open connect will have a direct connect more to Netflix, so could be very different then Other sites.

Re: Slow Streaming - post fast.com speeds

Its bridged to an RT68, using wireless from the router. To debug, I turned off wireless and connected directly to the modem and see the same buffering issues.

 

This is in a new home.

 

If Rogers has a direct connection to Netflix then the speeds should be higher in theory (assuming Netflix isn't the bottleneck).

 

What are other users seeing for fast.com - would be good to see some actual data.

I have Ignite 100U, CGN3ACSMR running in bridged mode to an ASUS RT-N66U.

 

Quick test over wifi connection give me 110 on fast.com and 127 on speedtest.net to the Toronto Telus server. The speed for the past week has been all over the place and yesterday the video quality on Shomi was so poor I gave up watching it.  However, Rogers has been digging up the main distribution box on my street, so I expect some poor results until they are finished.

Re: Slow Streaming - post fast.com speeds

Modem - CGN3ACR

Router - RT-AC68U

 

I normally connect via 5G Wifi (have separate SSID which I would recommend to everyone). However, for debugging I connected a laptop wired directly to the modem. I went through all of this with the Rogers tech on the phone and they said everything looks ok but performance is off (results below were 30-50/10 on speed).

 

It was all working a few weeks ago until I noticed streaming became choppy are started blaming my FireTV stick.

 

Here are current test results (all 5G Wifi): (D/U)

Speedtest (Telus Toronto server) : 115/11 

Rogers speedcheck: 124/11

Fast.com : 5

 

I don't think its the Wifi (since I connected directly to the modem). The modem is connected to a cable jack with a short cable and splitter (for cable box). I removed the splitter , signal levels go up slightly , performance doesn't change.

 

I can't stream the video below in 4k which I assume should play: plays for 5 seconds pauses for 30 seconds.

Re: Slow Streaming - post fast.com speeds

Check the following router setting:  LAN ..... SWITCH CONTROL .... NAT Acceleration:  enabled

 

Note the router firmware version as well.  The latest is ASUS RT-AC68U Firmware 3.0.0.4.380.3264    From the update log comes the following statements:

 

ASUS has been dedicated to cooperate with third party developers to come up with more innovative features.
To comply with regulatory amendments, we have modified firmware verification rule to ensure better firmware quality.
This version is not compatible with all previously released ASUS firmware and uncertified third party firmware.

 

The first statement is bs, to put it mildly.  The second statement is what counts. 

 

With this version loaded, you can't reload previous Asus versions or other firmware such as Merlin or DD-WRT.  This is a direct fall-out from the US FCC decision to lock out frequency control so that users can't change the operating frequencies of the router and interfere with Doppler Weather Radar.  So, although the first statement indicates that they are working with third party developers, at the present time you can't load other firmware.  Maybe down the road, but not at the moment.  

 

So, its kinda like a carrot and stick.  The carrot is the security updates and enhancements.  The stick:  the inability to reload previous or other versions in the event that an update results in poor router performance.  If you don't have this version loaded, you might want to consider switching to Merlin's firmware.  Food for thought.

 

Back to the main subject.  Load the free/trial version of pingplotter from www.pingplotter.com.  When you have that loaded, run a test session out to something like youtube.com.  When the application is running, right click on the display area, and enable all of the selectable items.  Right click again, select Customize view and select or enable all of the items.  The bottom area can be expanded upwards towards the bottom of the upper display area if you want to expand the lower graph scaling. Select Edit .... Copy as Image.  Dump the clipboard contents to something like MS paint, and then insert the image into a post.

 

Hopefully the pingplotter results might point to something in the path from your modem to the youtube servers.
 



Re: Slow Streaming - post fast.com speeds

I have firmware 3.0.0.4.380_3264. It looks there is a way to revert to Merlin, but don't see a need as router is solid.

LAN/ Switch Control/NAT -> set to Auto (text says CTF (Cut Through Forwarding) is enabled.)

 

I tried pingplotter, doesn't say much - i don't have those options. Router is showing 80% packet loss but that is probably just a reporting issue.

 

 

Here are current test results (all 5G Wifi): (D/U)

Speedtest (Telus Toronto server) : 116/11 

Rogers speedcheck: 133/11

Fast.com : 100 kbps (was 15 mbps a few minutes ago).

I've been seeing the exact same behaviour over the past couple weeks.  Not sure what's happening, but for just a few seconds speedtests to Rogers server on speedtest.net will be 1Mbps, then jump back up to 100Mbps, in the same test even.

 

I have the 60/10 package.

 

We've got a CGN2 in bridge mode to a Netgear R7000.  I did testing with a wired connection, 3 foot patch from modem to router, 10 foot from router to PC.  Direct connection without the router I see the same issue.

 

This can happen every 10 minutes, or it may not happen for hours at a time.  It's a real pain when you lose a customer on phone/chat (work from home) because your intrnet pukes out for a few seconds.  

 

If this keeps up, a new ISP will have to be sourced as I can't work with flakey inet.

Re: Slow Streaming - post fast.com speeds

Just called again - apparently this is confirmed known issue (slow streaming) as others have reported similar issue. No ETA but I am getting a full credit since the time it started once its resolved.

 

Speedtest/Rogers speedcheck are generally good for me (100+/10). But REAL world performance suffers.

Try streaming a 4K youtube video or test fast.com.

 

Fast.com is 2Mbps (currently) and I can't play a 4k video Youtube . Even 1080p videos stutter some times.  

 

No packet loss, Wifi ,etc. Its not a local home issue. This is a Rogers issue - maybe neighborhood or something. Maybe its the CDN (content delivery network).

 

Can everyone please post fast.com speeds ?

Re: Slow Streaming - post fast.com speeds

110 Mb/s with Firefox to 270 Mb/s with Opera.  Terribly unreliable as a data rate indicator.  I certainly wouldn't advise anyone to use it.



Re: Slow Streaming - post fast.com speeds

Its just a quick indicator and a tool in debugging.

Just because Speedtest show brilliant speeds doesn't imply your Internet is really working at the target rates across all types of traffic.

Re: Slow Streaming - post fast.com speeds

KrS14
I Plan to Stick Around
Here's a better metric.

When I get those 1-2 Mbps speed tests, I drop chats, and phone calls for work, and my rdp drops as well.

This is direct off the CGN2.

I'd say that's a pretty concrete result that there's something wrong.

Can you log into your modem, navigate to STATUS .... CM STATUS, copy the downstream and tables and paste them into this thread.  Those are the RG-6 cable signal levels and signal to noise ratios which might provide an explanation of why you're having problems.

Wish there was a way to do this in bridge mode :(. I'll have to reset it and get numbers.

With the modem in Bridge mode and the router in full router mode, connected to a pc  or laptop, use 192.168.100.1 as a web address in the pc or laptop.  That will work thru the router to access the modem's login page.  That address can also be used when the modem is in Gateway mode running a direct connection to a pc or laptop, but, when the modem is in Bridge mode with a follow-on router, thats the only way to access the login page.



Re: Slow Streaming - post fast.com speeds

I had to reset it as the default cusadmin and password didn't work.

Just as an aside to this, a Rogers contracted guy was across the street messing in the box today.  I'm pretty sure they have just hooked up a new house on the other side of the street, roughly the same time all this started.

 

I asked him if there was any known issues in the neighbourhood ovber the last couple weeks, and of course he says, " I don't know you'll have to call Rogers to find out".

You're signal levels are fine.  I wouldn't expect to see any issues due to where they are now.  The downstream ideal level is 0 dBmV, so yours are down slightly.  The signal to noise ratio is ok.  The upstream are elevated above their normal 36 to 40 dBmV range slightly, but, once again they're ok.  

 

The signal levels look pretty normal and are what I would expect as the external cable ages and the cable becomes less of an ideal insulator, the downstream signals drop below the ideal level and the modem output level goes up to compensate for the cable losses.  All very normal at this point. 

 

If there was a problem with the cable that was very fast, like, water in the underground cable shorting the cable, or wind pushing around an overhead cable that has gone thru several thousand cycles, then the signal levels wouldn't catch that.  If you had to restart the modem to regain internet service, that's an indication of a cable issue.

That's the thing, I don't have touch anything, it will just drop and come right back on it's own. I seriously doubt it's a physical cable issue. This neighborhood is only 7 years old. Others not in the same area are reporting the same behavior.

Re: Slow Streaming - post fast.com speeds

I'm Here A Lot

Rogers was able to fix my issues a few weeks ago. Unfortunately the technicians completely failed to document the issue in the ticket so I am trying to escalate again - otherwise back to square one.

 

Now a few days ago, issue is back again.

 

Youtube 4k playback stutters

Speedtest results back to 30Mbps (are up to 170Mbps at times)

Fast.com results at 1.5 Mbps

 

I am giving it another 2 weeks before I switch to Bell and not before I get credited back for the poor service.
