Re: Ignite Internet Gigabit - Slow Speeds

@AngryChicken  You are absolutely right that you can and do see this "slow connection" issue on new network connections in dual stack situations.  Here is what is going on: When IPv6 is enabled in the network, a modern operating system will first attempt to connect to a site via IPv6.  However, when IPv6 connectivity is broken for whatever reason, (OS networking (mis)configuration, IPv6 connectivity at the network level only partially working, issues with DNS resolution, etc.) the OS will wait for the initial connection to a site to time out and then should fall back to using IPv4 for subsequent connections, and that is why you see those subsequent connections working faster.

 

As a network engineer, you may find RFC 8305 interesting; others can read a synopsis of the issues here.

You can also test whether you are falling back to IPv4 here: http://he.test-ipv6.com/

 

Disabling IPv6 is only a workaround.  You need to fix the root cause, and the IPv6 tests that I posted earlier should point you in the right direction.  Microsoft does not recommend disabling IPv6; Also see their Windows IPv6 FAQ and tips for Advanced users.  Some have also posted fixes elsewhere in the Forum for issues affecting Windows installations.  (e.g. @Datalink 's post here.)  Most UNIX-based operating systems work fine out-of-the-box in dual-stack environments.

 

FYI, Ignite TV requires IPv6 and the Ignite set-top boxes do not handle it well when IPv6 connectivity breaks.  On every channel change, the STBs initiate a network connection using IPv6 when they establish a new stream.  If IPv6 connectivity is broken, the connection will fall back to IPv4 but only after the IPv6 connection times out, so when things break, it takes several seconds to change channels.  (The breakage typically occurs when Rogers does overnight maintenance.  Sometimes, the CMTS router basically "forgets" who received which IPv6 prefix delegation, and then stops routing packets to that destination, breaking IPv6 connectivity.  A simple gateway reset on the customer end "fixes" the problem; on reboot, the gateway requests the prefix delegation again.  However, it's not an intuitive fix for new Ignite customers.  They will try resetting their STB over and over again to no avail when the fix is to restart the modem.)

Re: Ignite Internet Gigabit - Slow Speeds

Nice! This is a great summary by someone who has specific expertise in Rogers' implementation of dual stack. I was suggesting this as a Band-Aid but I have Digital TV and which Rogers would like to wean me off of. I wasn't aware that Ignite (IP) TV uses IPv6. Cool!

Re: Ignite Internet Gigabit - Slow Speeds

I ended up putting the Hitron unit into Bridge mode only - forces it as only a modem.
Then went back to my Asus router.
No issues now.

Re: Ignite Internet Gigabit - Slow Speeds

Is ~200mbps normal for this time of day on a 1gig connection? Upload speed is 30mbps.

Re: Ignite Internet Gigabit - Slow Speeds

@Cepheus74  How were you connected to the network when you performed the speed test?  If you were connected using wired Ethernet, then 200 Mb/s is not good.  If you are connected by WiFi through an Ignite Pod, then 200 Mb/s is normal.

 

Edit: Your signal levels also look off.  Your power levels should all ideally be in the -7 to +7 dBmV range and your SNR should be 38 dB or higher.  However, your downstream OFDM channel looks okay.  What are your upstream power levels like and are you seeing a high number of uncorrectable codeword errors?

Re: Ignite Internet Gigabit - Slow Speeds

Its wired. I do have a 3db dongle on the end of my coax, left over from my previous installation.

 

edit: 3db dongle removed, same speed results.

 

This is my upstream.

Re: Ignite Internet Gigabit - Slow Speeds

@Cepheus74  That does not look good.  Your upstream power levels are way too low: around 40 - 45 dBmV is typical.  I believe that below 35 dBmV and above 52 dBmV are considered failures.  Also, DO NOT remove that 3 dB attenuator or else your upstream power levels will drop even more.

 

Your uncorrectable codeword error counts are not good either.  It's totally normal to see a scary-looking number of correctable codeword errors on the downstream OFDM channel but you should be seeing close to zero uncorrectable errors.  If I'm reading what you pasted correctly, you are seeing14928 uncorrectables!  With that many, your modem should be falling back to using DOCSIS 3.0... and if it isn't, that's a problem as well.

 

It also looks like you have A LOT of noise on your line.  From your power downstream power levels, you are getting plenty of signal... but the noise is dropping your SNR to unacceptable levels.  DOCSIS 3.1 does perform all that well with high noise levels.

 

Somebody at Rogers needs to have a look at this.  You can either call Tech Support or you can send a PM to @CommunityHelps  and ask them to investigate.  Either of those teams can get a Level 2 tech to check the signals to your modem, check the error stats on your modem and your CMTS, and check your area for noise, etc. and dispatch a senior tech or maintenance team to investigate further, if required.

Re: Ignite Internet Gigabit - Slow Speeds

I spoke with someone on a chat earlier and they said my line passed all their tests. Also I am getting 960mbps with a PC directly connected. I found out that my router is causing the slow-down oops, when I tried to connect a pc directly earlier it did not work not even with two different cables, now it does and with great speeds.

Re: Ignite Internet Gigabit - Slow Speeds

@Cepheus74 what are you running for a router?  There are two possible issues here: 

 

1.  the router doesn't have enough horsepower to run 900+ Mb/s; or

2.  the router does enough horsepower, but, QOS, or filtering of some type is running, requiring the CPU  to examine every packet, followed by a decision to do something with each packet, according to the QOS or filtering rules.  If you run a factory reset on the router and disable all functions except the firewall and wifi, you might find that the throughput thru the router is fine.  After that, as you enable individual functions, run a speed test to determine the impact of those functions.  Based on the results, you will find what causes the worst data rate impacts and know which should be left disabled.

Thanks.  That's great news!  I still stand by what I said regarding the numbers.  Some of your signal levels looked marginal to me but that does not necessarily mean that it's a problem.  It just means that a Rogers support tech needs to run tests to double-check that everything is okay.  As for the uncorrectable error counts, you can suddenly get a spike due transient line conditions and then everything goes back to normal.

 

You also can't see how things are trending with only a single data point and no additional context.  Sorry if I caused you any alarm.

 

I found out that my router is causing the slow-down oops, when I tried to connect a pc directly earlier it did not work not even with two different cables, now it does and with great speeds.


No problem.  I'm glad to hear that everything checked out okay and that you are getting good results with your speed tests!
