Re: Ipv4 not working

I am just running IP4 on my CODA modem.  Is there any benefit to Running IP6 only or IP4/IP6?  does one offer better speed than the other?

 

thanks

@mahomed

Run IPV4 and IPV6 on the modem unless you are having problems/disconnects. IPV4 has reached the maximum amount of IP address, so without ipv6 you may not be able to reach certain websites.

Re: Ipv4 not working

I had the problem of no IPV4 connectivity for 6 hours today.  Tried resetting everything but nothing worked.  Finally called in to tech support.  The tech fixed the issue instantaneously by Disabling and then Enabling Port Forwarding on the modem ( model CGNM-3552).  Apparently it is a known issue and this is a workaround for it.

I am on software version 4.5.8.21 and will get a new version 4.5.8.35 pushed to me within 48 hours which should deal with the issue.

So if anyone else has this problem try Disabling and then Enabling Port Forwarding .  Good luck!

Re: Ipv4 not working

Same issue as of 1am. My modem is bridged though and it not only takes forever for it to sync up properly but it refuses to assign any of my devices an ipv4 address. I can't even access the modem unless I set a static ip in the same subnet (192.168.100.1) but even then I can't route.

Called Rogers and they've been entirely useless on the matter cause they insisted everything works since they're able to ping the modem from their end.

Re: Ipv4 not working

Hello @RandomZero!

 

It's definitely strange that your router isn't assigning your devices an IPv4 address but we'll have to eliminate your router as a possible cause here before we can proceed. I know how frustrating it can be to troubleshoot these types of issues.

 

Please take your modem out of bridge mode and then connect directly to it. If it assigns an IPv4 address without issue, then you can focus on troubleshooting your router instead.

 

If however the issue persists with a direct connect, please let us know by PMing us @CommunityHelps! You can find instructions on how to PM us here.

 

Regards,

RogersCorey

Re: Ipv4 not working

I already removed my router and connect directly to the modem with both a laptop and a desktop and ipv4 still refused to work until 8am on its own. Your techs claim the issue is resolved but I've been having speed/sync issues since mid January and no one has yet to figure out the problem because it's intermittent and generally only happens after 9pm.

Hello @RandomZero,

 

While I'm glad to hear your IPv4 issue seems to be resolved, I can understand how frustrating slow speeds can be.  Let's see if we can get to the bottom of this.

 

Have you tried reaching out for support while the issue is happening?  If you'd like us to take a closer look and run some diagnostics, please send a Private Message to @CommunityHelps. For more information on our Private Message system, see this page

Internet not loading sites except Google, Facebook and YouTube.

 

Messaged Rogers over 5+ times and every single agent has been pretty much useless. Technician came and replaced my modem, worked for a couple hours then stopped. I have a similar issue with this thread over here.
https://communityforums.rogers.com/t5/Internet/Ipv4-not-working/td-p/375080

Ipv4 is not being detected.

Anyone know a fix?
Modem is set to dual, not ipv4/ipv6.
