Re: Rogers Hitron CODA-4582 Hardware


As for the desktop, same situation.  My guess is that the motherboard only has a 100 Mb/s ethernet port on it.  You might have to install a gigabit ethernet Network Interface Card if you want higher speeds on the desktop.  One item to check is to drill down into the advanced adapter settings of the ethernet adapter and ensure that the top data rate is set for Auto or 1000 Mb/s if that is available.  If its already at Auto that means that its already running at its highest data rate, or that possibly the ethernet cable that you're using is damaged, not connecting properly or is only built for 100 Mb/s.  If you have another ethernet cable around I'd give that a try.  Look at the back of the modem when the desktop or router is connected to the modem.  If the modem's connected port LED is amber, then the modem port is connected to a device port that is runnng at 1 Gb/s.  If the connected modem port LED is green, then the modem port is connected to a device port that is running at 10/100 Mb/s.  So, you have to determine if the connected device has a gigabit port and if the connecting cable is built to support 1 Gb/s rates and that its connecting properly at both ends.  There are fast ethernet cables still hanging around people's homes that only support 100 Mb/s as they only use two wire pairs within the cable instead of all four.  In order to run at gigabit rates, all four of the ethernet cable's internal wire pairs have to be connected end to end.  If not, then the port controllers at both ends negotiate downwards until they find some data rate that they are both satisfied with. 


Re my desktop ethernet, if I connect direct to the modem (default gateway mode), I get 150-200mbs which indicated to me my desktop ethernet is NOT the bottleneck (Its already set to autonegotiate as well.) After I setup modem in bridge mode, same cable connect to the either port1 or 4 of modem yields only 80-90mbs, which is similar to if I connect thru my router.

I thought with the same cable, connect my desktop directly to the bridged modem should still give me the higher speed but it doesnt. Direct or indirect via my netgear router gives me similar speed, hence I wonder if modem dropped to 90 once in bridged. Fyi, the router connection is green (consistent with my Router only capable 10/100.) The direct to modem connection is amber (which I thought I should get higher speed but dont)...

Ok, try this and let me know how it turns out.  With a direct connection, pc to modem (in Bridge mode), with the pc up and running, reboot/restart the modem, as in, pull the power from the modem, wait for 10 to 15 seconds and plug it back in.  After the modem restart, when the pc finally has an IP address, run a speedtest using the www.speedtest.net Toronto or Montreal servers, whichever is closer to your home.  

 

Your results might confirm a thought that I have in mind that the 4582 just doesn't like negotiating with a new device when that device is plugged into the modem and the modem is already running. Seems that you're better off powering up the device and then rebooting/restarting the modem. 

 

Edit:  note, this is for Bridge mode operation.  Also note, as you're reliant on the pc firewall to protect the pc, I would only run this configuration for the shortest time possible, then retreat behind the router firewall.  I only recommend this as a test configuration for the shortest time required to carry out the necessary test.

Bingo. Followed ur direction except I have to reboot my PC again AFTER the modem is reboot as it wont auto negotiate after modem rebooted. After rebooting my PC, then its able to re negotiate with the modem at a speed of ~190mbs (Same as what I would get in default gateway mode).

 

So with this hookup, my PC now basically has very little firewall protection since the modem is in pure modem mode. When the mode is in gateway mode, direct connection to back of modem is "safer" just because I am essentially hooking up to the "router" portion of it ?

@wongmich

The modem's router feature has its own firewall. However, without a standalone router, your LAN may be exposed to Rogers staff access, though I don't know to what degree, and no-one you can trust will answer this with certainty. Smiley Wink However, many subscribers just use the modem's router hooked to PC in Gateway mode.

 

Your reply hints, CODA FW needs improvement to better negotiate speeds on the fly without reboot. Though rebooting the modem didn't help me to get better speeds in Bridge mode. You can restart your PC ethernet adapter in Network Settings instead of rebooting the PC.

Re: Rogers Hitron CODA-4582 Hardware

yeah which is why I am hesitant to use the modem in gateway mode and use the built in router. 

But since I am now at Ignite150, makes it ponder if either I get a gigabit router (since my current Router limits it to 10/100), or just "trust" Rogers and just use the router built in into the modem, not my preference tho...

Only you can decide whether you trust Rogers.  Most people do (although they may not realize that).  It's not as if you can make an informed decision.

 

Choosing the best wireless router is hard -- lots of choices and they do make a difference.  But it is fairly easy to choose a good modem.  Perhaps the Archer C7 is an OK conservative / inexpensive choice.  Note: I have not done sufficient diligence to be confident in that recommendation.

 

Other people's recommendation may not be best for you -- we all have different criteria.  I'm biased in favour of routers that are supported by the OpenWRT / LEDE firmware project.  Few of us have a large sample of currently available routers to compare.

 

SmallNetBuilder.com seems to be a good place for reviews.

Re: Rogers Hitron CODA-4582 Hardware

@wongmich I only wanted you to run the pc to modem config (with the modem in Bridge mode) for a very short test.  Your results basically confirm my thoughts that there is something amiss with the modem to device negotiation.  

 

For now, until you decide what to do, I'd recommend running the modem in Gateway mode.  You can flip the modem back to Gateway mode from Bridge mode by logging into the modem, when its in Bridge mode, using 192.168.100.1   Reenable the Residential Gateway mode found in the Basic .... Residential Gateway tab.  Changing it back to Gateway mode in that fashion will flip the modem back to that mode with its previous settings intact. 

 

You could run your router in Access Point mode only if you wanted to use it for wifi purposes and let the modem run the DHCP function for the entire network.  Or, you could use the modem's wifi for now until you decide to buy a new router.

Re: Rogers Hitron CODA-4582 Hardware

Hey guys, apologies as I'm late to the game here but I just got this modem and the ignite 500 plan, the speedtests come in fine, 550Mbps down, 20 up, but I just realized my old router is the Linksys E1200 and it appears to be 10/100, so is that correct to say it will throttle me down to 100Mbps?

So then my second part is how safe am I running just the modem to my computer? As in, does it have the same firewall abilities as my old router?

Re: Rogers Hitron CODA-4582 Hardware

Given the choice of your current gear, I'll take a wild guess and say you're going to be pretty safe hooking your PC to CODA router & modem in Gateway mode. The reason I say that is this approach is mainstream for most internet providers now, and more geeky approach usually has some history roots driven by particular concerns and objective demands. If you were not concerned about these things in the near past, what would prompt you to get alerted now, and on what grounds? Smiley Happy

CODA-4582 DMZ Firmware Update Required for IP Passthrough

 

Hi Rogers,

 

The Roger's Hitron modems seem to be limited for allowing multi public IP addresses for using a feature called IP Passthrough in which the Shaw Hitron Modems do support.  Can you please provide a timeline for this feature to be included in the next Rogers Firmware update.

 

The main reason for this is that while some clients prefer to place the Hitron in Bridge mode to allow VPN tunnels for security reasons the current Firmware is still doing a NAT on the DMZ in Router mode, which prevents IPSec and other protocols not to be forwarded to these routers.  I have experienced some luck with IPSec on Cisco routers in bridge mode but very challenging when the Hitron is edge routed without the control of protocol forwards on DMZ.

 

Would be very useful to have a second IP when you need to stay secure and productive and give the kids the other IP for gaming with silly uPNP rewrites which are flawed in providing security with so many gaming ports open these days.

 

The firmware that Shaw currently uses with their Hitron Modems would be very helpful I'm sure for many Rogers customers.

 

Truly,

Frustrated Rogers multi client.
