Hitron CODA-4582 will not allow internet access for dlink DIR-850L after bridge mode

[NickO10]

Hi there guys,

Been trying to fix this issue for the past two hours but with no success. I have the brand new gigabit internet modem/router (CODA 4582) from Rogers. I don't like its wireless signal and want to hook up my dlink DIR-850L router to it for the boost. The firmware for the router is up to date, I have put the modem intro bridge mode by turning off the gateway function, and I have also reset both the modem and the router to factory settings about five times now. Problem is that when the modem is in bridge mode, it will not allow internet access to the router. The router is not broken or damaged as it had been working fine at a friend's house and the modem also seems to be in working order. I called the Rogers support but, as usual, they didn't help with anything. Anyone know the fix for this?

Thanks so much!

@NickO10 Sign up for the Beta Firmware Program, the latest Beta Firmware should fix the issue with 3rd party routers.

Send a PM to @CommunityHelps with the subject "Rogers Rocket Wi-Fi Modem Firmware Trial"

Tell them you have the new CODA 4582, and provide your Rogers Account Number, Modem Serial Number, and Modem MAC Address, these can all be found on the back of the modem, or login to the modem and the main page has this info

I have a D-Link DIR-880L, and I had the older HiTron CGN3 Black upright modem that had been working fine for quite some time in bridge mode. I too, don't like using the WiFi on these modems, and prefer standalone routers. I have the 250u Ignite package, and I noticed last week that my dl speeds were dropping drastically from averages of 320+Mbps down, and 21+Mbps up to an average of 3-7Mbps down, but uploads still staying at 21+Mbps. This led me to calling in to Rogers tech support, where I was informed that my network had been upgraded and my older black upright HiTron modem no longer supported my internet package and that I needed to exchange my modem for the newer CODA-4582 modem/gateway. Fine I said, exchanged my old modem for the new one, get it home and proceed to set it up. Out of the box direct to my PC, getting speeds upwards of 330+Mbps. So now I set it to bridge mode, and plug into my DIR-880L, run speedtest.net, dl speeds drop to 1-3Mbps over and over, again and again - uploads are still at the same 21-23Mbps... WTH?? So, now I'm on to D-Link tech support, factory reset router, try different router ports, different ethernet cables, still no change, downloads are still 1-3Mbps, uploads still 21-23Mbps, go back to direct to pc from modem, 300+Mbps down, 21-23Mbps up...  very frustrating... so now I'm thinking its bad downstream in the router and I go out and buy a brand new, exact same router, upgraded to the latest firmware direct from D-Link tech support, and still the exact same problem: 1-3Mbps down, 21-23Mbps up... I'm at a loss

This might be a lingering problem with communication between the 4582 and 880L .  There was an earlier issue where the 4582 would not assign an IP address to D-Link routers due to a problem with how the D-Link routers would connect to a modem (any modem). That's a D-Link issue apparently.  I believe that was taken care of with a firmware update to the 4582, and I haven't seen any other complaints with D-Link routers involved.  The DIR-880L firmware is dated 14 Nov 2016, which predates the 4582 release, so, there doesn't appear to have been an update for the router since then.  

Best bet at this point is for @RogersDave to have a look at this thread and consider the best way forward.  Expect a comment or request from him tomorrow.  Keep an eye on the thread, and watch for a number overlaid on your avatar at the upper right hand corner when you're logged into the forum.  Select the avatar and keep drilling down into the message inbox if you see the number overlaid on the avatar.

Thanks @Datalink - I had no issues with the older Black Upright HiTron modem in bridge mode, and would get dl speeds of 230-260Mbps through the DIR-880L, it just started slowing down drastically last weekend. And the only thing that had apparently changed, was Rogers had "recently" upgraded my network/internet package - telling my modem did not support my current package anymore...

[Datalink]

I don't get that switch routine.  Somehow I doubt that it was absolutely necessary, but, in the bigger picture, the sooner that customers switch to the 4582, the sooner that DOCSIS 3.1 can be enabled at the node.  

For now, can you log into the modem, navigate to the DOCSIS WAN page, copy the downstream and upstream tables and paste them into a post.  The copy and paste process will paste in the text contents of the tables.  This is usually the first place to look for issues.  We'll go from there, depending on what turns up.

I do not believe it is a problem with your router. I have the Coda modem as well and had the same issue. download speeds were great then they would drop off to around 2-3 mbps. I would reset the modem, called tech support a few times. There were times I even was on 2.4 and about 5 ft away from the modem and it wouldn't let me connect. I figured I would go to best buy and I bought a tp link ac3200 router figuring that would fix the issue by putting the coda in bridge mode. worked great for a couple of days then the same thing happened, went from around 185 mbps on my ignite 100 package down to 2-3 mbps. Called tech support, was advised to swap the modem, did. worked great for about 2 days, then happened again for a few hours, then the speed picked back up to 185 ish.... no idea what is happening. But don't think it is the routers..

[Gdkitty]

not 100% about the modem either.. as there are/can be many which work fine without the drops.

One thing to check.

Are you able to access the modems interface while its in the slow speeds?


Check your signal levels at that time, vs at a good time.
Will indicate if its a signal level drop, etc.

One also thing to do.. would be capture a few good traceroutes to say google.com at a good time, and then a bad time.

May help see if its a node issue nearby causing it.

[sikhness]

Was anyone able to resolve this?  I think the resolution was to get the latest firmware beta but that was quite a long time ago.  I now have the latest 2.0.10.28T2 firmware and am still not able to connect to the internet properly with my Dlink-868L router.

I have given up and switched back to gateway mode for the CODA 4582 but would like to use my dlink router instead.  Any help would be awesome!

Thanks!

Hi @sikhness,

Thanks for reaching out.  You've come to the right place! Our Community is a veritable treasure trove of information.

While I'm not personally too familiar with your D-Link 868L, perhaps our Community or Resident Experts @Datalink @gp-se @Gdkitty might be able to offer some guidance?

[Scionergy]

This seems to be an ongoing issue with using the modem in bridge mode with an external router. I also have the 2.0.10.28T2 firmware, and I have also reverted back to using the modem in gateway mode. I had even replaced the router thinking it was an issue with my router, but still experience slow download speeds (2-3mbps) running through the new D-Link.

I don't know why this post is marked as "Solved" when clearly it still isn't fixed...

[gp-se]

@Scionergy @sikhness

You both have D-Link routers that are having issues, so something with the CODA is not compatible with D-Link. I personally have been running my CODA in gateway mode for 10 months now without issue. Have you guys verified that your D-Link routers are running the latest firmware? Ensure the latest firmware is installed, then factory reset the D-Link and run it at default settings for a few days to see if it works. 

I had a TP-Link C3150, and now pfsense connected to my CODA without issue.

[sikhness]

Yes my DLink router is running the latest firmware and it has been factory reset, I made sure to do that first before trying to connect it up.

Then when I put a network cable from LAN1 of the CODA to the WAN port of my DLink, no internet connection is given.  If I put the cable onto one of the LAN ports on the DLink instead of the WAN, I get some minor connection where only Google.com loads and nothing else.

If I connect my computer directly to the CODA however, the internet works properly, but of course I need a router to split that internet connection.

@sikhness

Have you tired using another LAN port on the CODA instead of port 1? Also did you set the coda into bridge mode, let it reboot then plug the d-link from a LAN port on the CODA to the WAN port on your D-Link? Also verify the D-Link is set to router mode?

Since you connected the coda to a lan port on the D-Link and got internet access that makes me think the CODA wasn't put into bride mode.

Yes I tried using LAN port 4 as well and it was the same behaviour.  The CODA was set to bridge mode the entire time otherwise I understand there would be conflicts.  The DLink router was set to the default mode of DHCP (the other options are PPPOE and a bunch of other things that require a username/password).

The CODA was definitely in bridge mode (gateway features turned off) because I couldn't even access the UI anymore for the CODA, plus I had restarted the CODA a few times to make sure it took the changes.

With CODA in Bridge mode hooked Port1 to router's WAN, what speed your D-Link router led shows on WAN port: 100 or 1000Mbps? I noticed current CODA FW having issues with some routers auto identifying ethernet cable type and speed capacity. Also try a different CAT6 or 7 cable. If it shows 100, login to the bridged modem (don't reset) or router and set it manually to 1000 on port 1. Also try to manually assign your D-Link router a new MAC address in the range matching CODA MACs range, and see if speed improves. It all may have something to do with CMTS or CODA software not compatible well with D-Link FW. I noticed similar issue with some PC Ethernet cards and other router makes in Bridge mode. Let us know the outcomes of your above tests. If you don't do manual tests above, then the conversation will go on forever this way:

- you say "my speed is low"

- they say "it should be OK" 

Also, try installing alternative FW into D-Link like DD-WRT or other best supporting your router chipsets with open or closed source drivers (as per router FW forums you need to research), and see if the result will differ with default alternative FW settings. You can always revert to the router factory FW.

I too have a DIR880L router and it was working great with the CODA 4582 in bridge mode.  Recently there was an outage in my neighbourhood and I lost cable, internet and home phone.  After the outage was over, I had the problem of slow download speeds and slow internet browsing through the router but when I connected my pc directly to the CODA 4582 modem, the speed was normal (>300Mbps) and internet browsing was fast.  After talking to customer support and rebooting the modem and router several times, things would work fine then after a day, back to the slow speeds from my router.

I decided to factory reset the CODA4582 and operate it in gateway mode.  Download speeds were normal through both wired and wireless connections to the CODA.  On a whim, I connected my DIR880L router to the modem (which is still in gateway mode).  My router is running as a router (not AP) and I assigned my router address to 192.168.200.1 and channel 11 and it works!  I don't know how or why, but now I have two wireless networks, 192.168.0.xx from the CODA and 192.168.200.xx from my DIR880L and the download speeds are the same.

I was under the impression that to connect a router to the modem, 

 either the modem had to be in bridged mode with the connected router in router mode handling DHCP

 or the modem is in gateway mode with the router running as an AP.

For now, my setup is working fine and am not going to mess with it until it's broken.

[Datalink]

@sagaboi you can run a router with the modem either in Gateway or Bridge mode.  Ideally the modem would be running in Bridge mode if you wanted to use the router as the network firewall and DHCP server.  That's a normal configuration.  If the modem is running in Gateway mode with the router running in full router mode what you have is a double NAT situation, first thru the modem, and then thru the router.  That isn't ideal, especially if you have to run any port forwarding for applications or games.  It will work with or without the router firewall up and running.  The modem will act as the DHCP server for anything connected to it, including the WAN address for the router.  The router will then take that address and use it as the base address for its connected devices if you don't override the routers LAN IP address range.   If you adjust the routers LAN IP address range, as long as the address range for the router is beyond the IP address range for the modem, this will work.  Now if you happen to have IPV6 up and running I believe this will work all the thru to the devices that are connected to the router but don't quote me on that on.  

As for the router firewall, if you have it up and running you will have a walled off network within a network.  There are arguments for and against, but, at the end of the day this will work.  One exception will be if you are trying to reach a device which is connected to the router from a device that is connected to the modem.  Its possible that you might see issues in reverse as well.  I'm thinking specifically of a printer attached to the modem, and, you're trying to print from a device connected to the router.  There should be traffic back and forth from the device to the printer, but, I suspect that the router firewall would stop the return traffic to the device.  Once again, don't quote me on that one.  A small test would confirm or contradict that theory.  

As far as the router losing speed after the power outage, that would suggest to me that the CMTS also lost power but didn't return to its original state when it was powered back up.  There is no logical reason for there to be a speed issue with the modem in Bridge mode.  There have been issues with D-Link routers and the 4582, but I believe that was resolved months ago.  So, there might be an issue afoot with the CMTS and 4582 (in Bridge mode) with certain routers connected.  That would take a network engineer to look at the CMTS configuration and its files to determine if anything is amiss.  Tech support wouldn't be able to do anything about this issue.  

When you said that "After the outage was over, I had the problem of slow download speeds and slow internet browsing through the router but when I connected my pc directly to the CODA 4582 modem, the speed was normal (>300Mbps) and internet browsing was fast.", was that with the pc connected via ethernet to the router?

Can you log into the modem and:

1.  confirm which Software (firmware) version is loaded, as indicated on the Status page.  That page is displayed automatically when you log into the modem. 

2.  navigate to the STATUS .... DOCSIS WAN page, copy the downstream and upstream table (and everything in between) and paste it into a post.  The copy and paste process with paste in the text contents of the table.  Those tables are the cable signal levels and signl to noise ratios.  I'm just wondering at this point if there are any signal issues on the go.  

Edit:  I've sent a request to @RogersDave to have a look at this.  He's a Network Architect with Rogers who can address this issue at some point.  It won't be soon as he hasn't been in the forums lately, but, it will be on the list of items to read thru.
