1) You can not connect a router to a DPC3825 as it comes. Rogers does not tell you this

2) The documented password and login are incorrect, Rogers does not tell you this. The correct login user is cusadmin. The correct login password is whatever you set for the wireless connection.

3) There is a problem with multiple users connecting to the box; I was not able to properly figure out the problem before giving up.

4) You can call Rogers and have them reprogram the box as a dumb bridge. The Rogers technician will log into your box as a super-user, will turn off the DHCP server, turn off NAT, and turn off the wireless. You can then hook up your router to port 1 only, and the DPC3825 will function as a DOCIS 3.0 modem only. Roger does not tell you this. It is not easy to get this information from the Rogers support.

5) Rogers will not give you the super-user login information, and Rogers will not give you documentation on how the super-user can program the box.

6) I expect Rogers is planning on having every user that wants to hook up a modem to their DPC3825 first waste 2-3 days thinking they have a network problem, and then a large amount of time getting through their lousy support phone service until the reach a technician, and then wast more time until the technician eventually explains to them what is going on. Besides intentionally wasting their users time, this also costs them money and damages their reputation; I can't think this is a good thing.

7) Whomever is responsible for this at Rogers deserves to be fired.

A little story for the beginning. I did not want to pay rent for my 6 years old Motorolla modem anymore so I called cultomer service and told them I want to purchase a N gateway device. They said fine and I should see a charge added to the next invoice. Next morning a Rogers technician came and I was stunned to see him bringing a G SMC gateway to my house. I asked him if he understands the difference between G and N, and if it makes sence to him that someone would pay $150 to upgrade the home WAN from G to N and get same G in the end. Obviously I did not allow him to change my old Motorolla (that had a LinSys WRT54 G router connected to it) to that second hand SMC G gateway. Same day I went to the Rogers store in Richmond Hill and exchanged my Motorolla unit for a Cisco DPC3825.

 

Now to the DPC3825. While still at the store, I was not sure if this model has N or G WAN, as I was not familiar with this model. There was no any marking on the device, on the box, or on the CD inside the box that would tell this is a N type gateway. I had to take a word from the clerk at the counter that this is indeed a N device. When I came home to set it up, I had to call techsupport because of the initial password issue - as someone already mentioned here, the default user name and password are not blank as the user manual tells you. Once I logged in, I was able to confirm this is a N device by checking the transmittion rate setting which had options up to 270Mbps.

 

After spending some time with it I was able to set it up more or less OK. Im saying more or less because I still was not able to get a N-connection with my Shuttle home theater PC that has a N-Wifi card. Still do not know if this was a issue with the Shuttle or with this Cisco gateway which by spec has Draft 2.0 N spec. So if you are more technically savvy than me you may want to research if N Draft 2.0  really means full support of N or it is just some draft version of N that may not be supported by the client equipment in a few months from now.

 

Also, my DPC3825 sure has a bug with the system clock. There is no setting that allows you to change the system time and apparently the gateway is supposed to get time from the time servers from the internet, but it does not do it properly - with my EST time zone it shows the system time 6 hours ahead which is totally disapointing.

 

Someone here mentioned he had a problem seting the  LAN address space to 192.168.1.x . I did not have that problem. The gateway worked for me with both 192.168.0.x and 192.168.1.x  settings.

 

As to the range - it seems OK to me and I get 4 bars out of 5 anywhere in my 2-storey house and I get 2-3 bars outside of the house in the far corner of my backyard which is 20 m away from the house and in total 26 meters away from the gateway which is in the basement below ground level.

 

Also someone here mentioned issues with multiple connections to the box. I tried at least two simultaneous connections, one from a XP, second one from a Linux box, both were streaming video at the same time from the internet. I did not  notice problems with that, though I did not set up users on the box so a login would be required to connect to the internet.

 

Overall my impression is this device is not ready for mass deployment. Beside of the system time bug, the reporting capabilities are close to non-existent.  Most of the reporting options I tried returned "Unsupported at present" error message.  There is no option for firmware upgrade. May be Rogers will be doing it remotely.

I have a friend who recently had their internet upgraded, I'm not a Roger's customer so I'm not certain which package they have, but they received the Cisco DPC3825 as their modem/router.

 

Shortly before they got their DPC3825, I was on their network and found out that they were triple NAT'd, I rewired a portion of their network and updated all of their wireless routers and they had less speed problems and their problems with some devices not being able to see other devices went away.

 

Fast forward to several weeks of living with the Cisco and me being out of the area on vacation. I went over this evening and they told me that network shares were not working correctly. The last thing I would have suspected would have been the Cisco, but any device connected to the Cisco via a wired connection or wireless had problems with network shares.

 

To resolve the issue I turned wireless off on the Cisco, removed all of wired connections and replaced a wireless router that the Rogers tech had removed. The Cisco DPC3825 functions as modem, router(NAT) and DHCP server, but it only has a single physical connecton to the LAN side of a 3rd party wireless router. All other devices are now either wired to one of two wireless routers or connected wirelessly and everything is working much better.

 

Not certain why the DPC3825 is causing problems, but when I suggested having him call Rogers Tech support for assistance he rolled his eyes and went with the option I described above. I do work for one of Cisco's competitors as a technical support engineer and I have a hard time thinking that Cisco would have let a product with such an obvious flaw out the door, so I'm going to have to blame the custom firmware that Rogers is using.

@Octo since they have their own router they should call Rogers and ask to have their cisco set to bridge mode. It will take about 1 min and then it will just act as a modem and that should remove 1 level of nat and change their network back to it original state.

My dad recently changed my isp to rogers and it is completely horrible. We have this DPC3825 router and it is completely garbage. Not once have I even been able to log into the wifi from my ps3 and my dad signed a 1 year contract with them so I guess I wont be playing online ps3 for a whole year. I also had extreme problems with port forwarding so I called rogers, the told me to call cisco so I did, than cisco told me to call rogers and yet again I followed, than when I finally called rogers they told me to check here on the help section and find the solution (which was basically a way of saying "go **bleep** yourself"). And that is how rogers **bleep**ed up my online experience, we are never going to use rogers again after the contract is done.

@Anosh if you have a wireless router call Rogers and get them to change your DPC3825 to bridge mode and use your own wireless router instead.

You would never guess, dude, but the default password is “password”.

I tried few most common passwords with the login name you gave on my new DPC3825 and “password” logged me in :-)

Isn't that fun? Thanks for your help with login name.

 

So whoever searches for “factory” login/password for Rogers’ DPC3825 try cusadmin/password

Yesterday, Sept 1, I just had a technician upgrade my old Motorola Surfboard modem to this Cicsco DPC3825. I selected the in-house installation option, when I had the HiSpeed Internet upgraded to the "Extreme" package, from the previous "Express".

 

 So far, it's been great for speeds. speed test

 

HOWEVER.....

My wireless connection has been dropping, after some time of continous use.

 

(I currently run 3 macs in the house, a mix of Snow Leopard 10.6.8 & Lion 10.7.1, and a Windows XP w/Wireless G).

 

I first thought it was a Key Renewal issue:

Wireless > Wireless Security.  The default is 3600 seconds.  I've changed that to a lenghthy 43200 sec = 12 Hours.

 

It seemed to help at first, fewer wifi connection drops.

BUT then PROBLEM: my sister wakes me up this morning complaining of Wifi troubles on her MacBook Pro. Internet still works via wired connection on iMac. I check my MacBook Pro: connection timed out, cannot connect to my Wifi network, even though it just worked before bed (WPA2 Personal key all setup properly on all machines).

 

I think it could be an issue with the default Wifi Protected Setup.

Wireless > Basic Settings. "Wireless Configuration"

I have since de-selected Wifi Protected Setup, and went Manual instead. I already had setup my own SSID & WPA2 key, so it was already using these Wireless Security settings. But I suspect this "Wifi Protected Setup" default is causing the wifi connection drops & time outs when trying to reconnect; this new WPS may be causing more trouble than hlep!

 

Hope this helps folks. I'll keep y'all updated if anything changes.

@sixsteps:

 

nice posting!  A number of others have posted inthe past complaining of the wireless performance on the DPC3825.

 

Your posting sounds like a good synopsis of some problems you found, and solutions you developed to handle them.

 

Thanks for the effort!  Rogers Support take note!!!!
