Re: Hitron CODA-4582 in bridge mode drastically slower dl speeds through D-Link DIR-880L router

@sciaticman, run a factory reset on the router.  After the router reboot, disable every function on the router except the firewall and DOS protection if that is available and then reboot the router again.  After the reboot, run a speedtest using the www.speedtest.net Toronto Rogers or Montreal Rogers server.  Have a look thru the following response post which is very similar to your situation.

Re: Hitron CODA-4582 in bridge mode drastically slower dl speeds through D-Link DIR-880L router

@sciaticman at this point, you would have to run speedtests as you enable various functions in order to determine which function(s) cause the throughput to drop.  Thats simply a matter of processor horsepower and the functions that have been enabled.  

 

Fwiw, there must be two versions of this router.  There is a rev A1 which has a Mediatek MT7621A dual core SoC @ 880 MHz Processor.  The marketing page for the 882 indicates a 1.4 Ghz processor, but, there doesn't appear to be any technical data anywhere to back up that claim.  So, if this is a recent purchase, you might have either processor onboard.  The 880 Mhz processor would be slow when you have certain functions enabled in the user interface.  The 1.4 Ghz processor should be ok.  For 500 Mb/s and 1 Gb/s, I would recommend either a 1.4 or 1.8 Ghz processor, preferably the 1.8 Ghz processor for an all in one consumer router.  You might have to do some homework to determine which processor you have.  If its the 880 Mhz processor and this is a recent purchase, I'd return it and look for a router with a 1.8 Ghz processor.

Hardware Version: A1

 

As soon as I disabled the QoS list the speeds changed for the better. I have since assigned a static IP address for my PS4 and my son just went online to play his GTA5 and without me telling him what I did to the router, he immediately noticed a huge difference with no lag in online playing. 

 

I haven't tinkered with any of the other settings as I have reached my limit in router knowledge......lol. But I will research more and educate myself more.

 

Thanks again for your help!

Code-4582 bridge mode terrible speeds

 

Hi,

 

I previously had an ignite 150 package with the ignite modem. I had that in bridge mode to a dlink dir-867 router and consistently got between 120-180mbps on the wired and wifi. I upgraded my package to 1gbps and they gave me the coda 4582. Using it as a router i get roughly 400 mbps wifi and 700-800mbps wired.

 

However as soon as i put it into bridge and run it to the dlink dir 867 i get roughly 100mbps on wifi and 60-200 mbps on wired. As far as i know the dlink dir867 supports much faster connections and therefore should be outputting near gagabit speeds.

 

Anyone have any ideas? Rogers will not help as the modem speeds test within "acceptable range". The tech that came to my house suggested that i put my dlink in bridge mode and leave the rogers coda as is but i didnt understand that.

Hello, @BadModem.


Welcome to Rogers Community Forums! 🙂


Thank you for posting your concern in the Community. I appreciate you testing the speed when the modem is in the gateway mode; this is a good troubleshooting step. 

 

Did you get a chance to go through this thread? Is QoS feature enabled on your DIR-867? Have you tried a different Ethernet cable between the modem and the router?

 

Also, you can check the firmware updates and attempt a factory reset on your router. 


Keep us posted. 

 

Cheers,

RogersMoin

Re: Hitron CODA-4582 in bridge mode drastically slower dl speeds through D-Link DIR-880L router

@BadModem we've seen this same issue with D-Link routers previously.  Its been a while so I don't remember all of the issues, but, as @RogersMoin points out, enabling the QOS is one possibility.  Personal opinion I'd do the following;

1.  Run the following with the modem in Bridge mode:

2.  Run a factory reset on the router and leave the settings at their default value after the reset (more to follow);

3.  Run a wired speedtest.   The goal at this point is to get the wired data rates up to the modem (in Gateway) data rates:

4.  Depending on the results, log into the router and tab by tab, disable anything and everything, leaving the firewall up and running.  I'd disable IPV6 at this point as well.  You could run a speedtest after disabling all of the items on a given tab, just to see what turns up.  At the end of disabling all of the various items on all of the menu tabs (except the firewall), reboot the router.  

5.  Run a wired speedtest after the reboot to see if you're at the same speeds as the modem running in Gateway mode.  At this point you should be there, unless there's an issue with the connecting cable between the modem and router.  If you look at the back of the modem, specifically the connected port LED, it should be flashing amber, indicating a 1 Gb/s connection rate with the router.  Flashing green indicates a 10/100 Mb/s connection rate with the connected device. 

 

Assuming that you get to a point where the throughput data rates for the router are what they should be, set up your wifi and test the throughput rates.  Please have a look at the following post, specifically the wifi settings and applications to check out your wifi environment to see who you're competing with for clear wifi channels:

 

https://communityforums.rogers.com/t5/Internet/slow-wifi/m-p/429489#M54216

 

Those wifi settings are applicable to any modem or router for the purpose of running the highest data rates possible.  These days there are some routers on the market which have 160 Mhz wide channels available for the 5 Ghz network, but, those 160 Mhz wide channels are very difficult to run unless you happen to have access to the middle Dynamic Frequency Selection (DFS) channels, which the router would have to provide.  Outside of that DFS range, even with 160 Mhz set in the router, the router would probably default down to 20, 40 or 80 Mhz wide channels due to the clear channel check that is done prior to every transmission.  For the present purposes, setting your router to run a combo of 20/40/80 Mhz wide channels will probably result in the max wifi data rates possible for your location.  It will depend on the nearby competition from your neighbours.  

 

Fwiw, that router has a MediaTek processor onboard, so, how it reacts to enabled router functions isn't known.  That is to say, enabling functions that cause data to run through the processor in order for the processor to determine what to do with it will slow down the throughput.  Items like QOS, keyword filtering, URL filtering, etc, anything that requires the processor to determine what type of packet any enroute packet happens to be, and what to do with it, ie, give it a higher or lower priority as per QOS, delete it due to any filtering, etc, etc, that takes horsepower, and results in lower throughput.  At low speeds, 100 Mb/s for example, all of those functions won't impose a problematic load, but, at gigabit rates, you need significantly more horsepower from the CPU to run at those rates and with any functions enabled.  Looking at the wikidevi site, that router only has a dual core 880 Mhz processor.  Personal opinion, thats at the low end these days for gigabit rates.  If speed is important, disable all of the functions except for the firewall, any deep packet inspection, and wifi.  You should be able to see higher data rates in that configuration.  Here's the wikidevi site:

 

https://wikidevi.com/wiki/D-Link_DIR-867_rev_A1

 

Fwiw, my Asus RT-AC68U (800 Mhz processor) can run 930 Mb/s down 50 Mb/s up in an IPV4 speedtest with nothing but the firewall and Trend Micro protection running.  The upload rates would probably run much higher if Rogers allowed it.  IPV6 data rates take a serious hit due to the packet inspection with Trend Micro's protection, running far slower than anything I see with IPV4.  If I were to run any other functions, those data rates could be greatly reduced.  

 

The replacement RT-AC86U has a 1.8 Ghz processor, which is far faster,and more suitable to gigabit rates.  

 

Fwiw, what you might find at the end of the day is that the 867 simply doesn't have the processor power required to run at gigabit rates and run the functions that you're looking for.  It might be time to look for a faster router, even if the 867 isn't very old.  I'd recommend a 1.4 Ghz processor as the lowest choice for gig rates, preferably faster if the budget allows for it.  What you might find is that the modem's wifi is actually faster for the use that you're looking for.  That's a combination of Intel's Puma 7 processor and the wifi chipset.   Unfortunately the modem doesn't offer anywhere near the same functionality that you find in a router Smiley Sad

 

Fwiw, hope this helps.

THank you for your detailed reply. I ended up switching to an asus RT-AC66U B1 and am now getting giagbit through the wired and acceptable wifi rates.

Re: Hitron CODA-4582 in bridge mode drastically slower dl speeds through D-Link DIR-880L router

@BadModem that RT-AC66U B1 apparently is the same hardware as the RT-AC68U, so, for the purposes of updating the firmware, you can use the RT-AC68U firmware.  The AC66U is marginally faster than your D-Link router as the AC66U has a 1 Ghz processor versus the 880 Mhz processor in the D-Link router.  Depending on what you need to do with the router, you might find that the AC66U is still under powered.  It all depends on what you're running thru the router.  If you use a VPN then you should be looking for a router that has Intel's AES-NI hardware support, which the AC86U has.  If you run a VPN from a laptop/desktop, I'd expect the laptop/desktop to already have AES-NI support.  Here's a link to a widipedia article on AES-NI:

 

https://en.wikipedia.org/wiki/AES_instruction_set

 

One thing to note is that the Broadcom processors which are used in the Asus routers, use hardware acceleration to run high speeds.  That is to say, the data essentially bypasses the processor where possible, allowing you to run at data rates in the 900+ Mb/s range.  That hardware acceleration can be disabled by functions such as QOS, and a few others, so, the Asus router is not immune to the issue of functions that cause the data to route thru the processor for further processing which in turn drops the throughput rate.  The difference in this case is that this is a known issue and users have access to the hardware acceleration setting.

 

With the RT-AC66U B1, you can run Merlin's ASUS-WRT.  If you're not familiar with that firmware, its an enhanced version of Asus's firmware, where Merlin will correct issues with open-source portions of the firmware and add functions that enhance the usefulness of the firmware.  Merlin, aka Eric Sauvageau is based in Montreal and has been developing his enhanced firmware version for several years now, with a loyal following running his firmware on pretty well all supported Asus Routers.  The most recent notable addition has been DNS-over-TLS which can be used with DNSSEC.  That combination provides security for the IP address lookups that are provided by Domain Name Servers.  Merlin also updates the firmware's open source components when they become available, so the end product is simply a better, more secure version of the original (stock) firmware. 

 

Other developers have also come up with their own additions which includes Malicious IP blocking and country blocking (Skynet) and add-blocking (Diversion) plus a few others.  They require a USB flash drive to be installed, after which the Asuswrt-Merlin Terminal Menu, "AMTM" can be loaded, which in turn facilitates the installation of the other available add-ons.  Fwiw I use Skynet for country blocking to block known sources of attacks, and Diversion for add-blocking, which works very well.
