Re: Unable to load certain website(s) and or videos

For sure, glad to!  This is the first time I've had the chart looked at since having the CGN3 swapped out for the CODA-4582 & part of the RG6 replaced outside.

And in the meantime, I've got band steering disabled, as I've always preferred the separate networks for devices that benefit from the extra speeds on 5Ghz & the extra range of 2.4.

As for IPV6 with Mac, totally understand and all good!  To be honest I don't even quite know the benefits of IPV6 over IPV4, most of my knowledge of network related things come from the diagnostics I've done and info I've got through the process haha.  From what I read briefly it appears it is more secure and offers more IP addresses, but if IPV6 is the cause of these issues in particular it seems IPV4 wouldn't be too drastic of a downgrade.  If it makes a difference, we've had no issues of this nature in the few months we've had the CODA modem, just the latency spikes to 200/300ms and 1% ish packet loss, this issue is entirely new, and I haven't changed any settings since we initially got it set up.  I also did a search and found that IPV6 settings are in the advanced network settings for OSX, it looks like it is set up, as IPV6 is set to automatic with a "router" & long sequence of numbers and letters.

Re: Unable to load certain website(s) and or videos

Are you having difficulty with certain (Rogers) websites?  Here are some items to check to get things working again:


1. Make sure that you have Javascript turned on in your browser settings.

2. Make sure you don't have a pop-up blocker enabled.

3. Make sure you don't have any "extensions" like adblockers enabled.

4. Try a different browser.

5. It's always good to have a "clean" browser as a fallback so that you don't have anything blocking progress on certain websites that require some or all of the above.

6. Try using Incognito Mode in Chrome (Private Mode in Firefox or Safari) as this usually bypasses any problematic cookies or cache issues.

7. Try clearing cookies, cache and reboot your PC.

8. If you're using a VPN, or any other "non-standard configuration", disable it temporarily.

Re: Unable to load certain website(s) and or videos

So I have an interesting issue that Support couldn't deduce. They have referred me to their Engineering Department but I'd thought to post here just to try to get other ideas for a solution.



For some reason, certain wifi-connected devices can't access certain websites. These websites include amazon.ca, bestbuy.ca, and canadacomputers.ca just to name a few. However, on the same devices, websites like youtube.com and ebgames.ca work just fine. Also, this trend holds true for any respective apps installed on the device so it's probably not a DNS cache or browser issue. 


Additional Info:

-modem is the Ignite Modem(Arris XB6)

-Wired devices such as my pc work just fine. It can access any and all sites without trouble

-the problem seems to jump around between all wifi devices on the network, so the problem could be happening on a certain device and not others, but then later the same device may work perfectly fine but the other devices may now have the issue

-the problem devices still have an internet connection, just not to certain websites/apps

-I think this is important. In my router settings under "Connected Devices", the devices that do not have the problem says that they are connected via Ethernet. Don't know how since it is a phone but that is what it says under the "Connection" column. The problem devices say they are connected via the 2.4G wifi or 5G wifi


If anyone has any input, I'd greatly appreciate it!

Re: Unable to load certain website(s) and or videos

@pinkpather101 try this, log into the modem and disable IPV6 for test purposes.  That might cause problems for the Xi6-A or Xi6-T set top boxes, but, the object of the exercise is to determine if IPV6 is causing the problem.  


So, log into the modem, disable IPV6 and then reboot the modem and any affected devices.  See if that resolves the issue.  If it does, that would indicate that there's an upstream problem with IPV6, most likely at the Cable Modem Termination System (CMTS) which provides data and control over modems connected to the CMTS. 


If not, then I'm wondering as well.  


Remember to log back into the modem to reenable IPV6 and then reboot the modem.  On the other hand, if the set top boxes work without IPV6 and you don't see any lag issues which channel changes or video loading, you might want to consider leaving IPV6 disabled, looking for any problems caused by the disabling. 



Edit:  Are any wifi laptops affected?  If so, when the modem has IPV6 running, run a trace to the affected web site, using both IPV4 and IPV6.  To do that, using a command prompt type in:


tracert -4 amazon.ca


tracert -6 amazon.ca


When that is done, select the trace results and use Ctrl c to copy the selected data.  


Paste that data into a post using a right click .... paste, or Ctrl V.   For the IPV6 trace, delete the IP address for hop #1 as the it the modem's IP address which shouldn't be posted to an open forum.  


The question here is, does the IPV6 trace stop at some point, such as hop #2 and then simply time out after that?
