Port forwarding on DPC 3825 Cisco Gateway
Why does Cox not allow port forwarding on the Cisco DPC 3825 gateway? You can't even update the firmware because that's under Cox control too. As I see it it's simply a way for Cox to make more money by making you purchase the premium tech support for $100 and so much a month thereafter or a one time $60 to set it up for you. For $180 a month I'm not paying more money. I feel like I'm being ripped off! Here's what happens... log into gateway>applications and gaming>port range forwarding>enter external start and end port, internal ip address, start and end port, enable and click save. Pop up stating "The page at 192.168.0.1 says: the setting of port must between 1~65,535: 0" . I certainly didn't try all 65535 port numbers but any number I did try didn't work. What gives? Anyone else have a problem with this?5.7KViews0likes3CommentsCisco DPC3825 Only Getting 54MBPS
Hello Customer Support, I am located in Orange County and I have my DPC3825 configured for B/G/N Mixed mode. While sitting next to the wireless router, I can only get 54MBPS on my laptop. I know that when I am at work or others' houses, it indicates I am connected at 130MBPS. Can you advise what is the best configuration details to get back to at least 130MBPS? My current settings are: B/G/N Mixed mode. 2.4GHz Band. Auto Channel. Everything else is default. *** Lastly, my wife's VPN continuously drops out every 5 minutes connected through this router. Any suggestions? Thanks very much, -king kong4.8KViews0likes11CommentsCisco DCP3825 and the IGMP Proxy setting
I am trying to either enable or disable the Internet Group Membership Protocol (IGMP) Proxy on my Cox firmware'd Cisco DCP3852. According to the modem's help guide, it should be located in the Management tab under Administration. It is not visible. I believe the option is still available, but it has been hidden by the Cox firmware installed on the modem. Has anyone been able to find a way to enable or disable the IGMP Proxy setting? I'd really like to be able to use my wired desktop with my Chromecast. Elsewhere, If I absolutely have to, how would I go about requesting a different model of modem?4.5KViews0likes3CommentsRandom high peaks of latency/ping (Tucson Area)
During the past few months i have had a sudden peaks of ping/latency, the problem is that when i play game or videos online i have sudden "disconnects" forcing me to refresh the webpage or re-enter the game. i have called support a few times, in which they were able to minimize the problem but it is still present. MODEM =Cisco DPC3825 what i have done so far was to: -reset the modem (a lot of times) -Connected it via cable instead of wireless (did nothing) -Moved the modem closer to where the laptop is. -Changed the Wireless Standard Channels to those with Acceptable interference -Changed the Wireless security mode to WPA2-Personal (in my opinion this helped quite a bit) Everything else was done by the Support Service. After this, the problem was still occurring so i decided to test it with another laptop/device, and it appears the problem is withing the modem/service because all that devices that i tried had the same problem. here is the test i usually do to check how my ping is doing. the left one shows when i am not using any applications that are connected, and the right one its when i have the browser or any games open.4.2KViews0likes5CommentsUpgrade Firmware for Cisco DPC3825
I've been experiencing inconsistent download and upload speeds the past few days. I've done a few speed tests throughout the past few days and my download speed is, for the most part, fine and sort of consistent. Usually about 30-40 MBPS. As for my upload speed, it is very inconsistent and is constantly dropped. Making it difficult to load pages, watch videos, stream, game, etc. It sometimes will drop to as low as under 1 MBPS. It varies from high 20's to around 15-20, below 10's etc. I've tried resetting my router using the reset button, unplugging the power cord and even tried a hard reset, but to no avail. I've googled around and read some discussions and thought it may be that my router needs an upgrade on its firmware. I see that you guys do that automatically, but a few devices may fall behind here and there and I was wondering if that was the problem with my case.3.2KViews0likes3Commentsfirmware upgrade for my DPC3825 WiFi Modem

I have recently changed toCox and am using theirrouter by Cisco model# DPC3825.My house is small, under 1,000sq.ft.My problem is thatI cannot walk into another room without losing signal drastically. I can forget about enjoying my mornings sitting on the porch as I surf the internet. Trying to determine if this is as good as its going to get so I can jump ship. With my last service provider I used my own router which is so out dated but I could pick up signal as soon as I pulled in my driveway. With Cox's signal I can't walk out my front door. Very disappointed.2.5KViews0likes2CommentsDPC3825 router/modem combo unable to port forward fully
I have the DPC3825 router/modem combo. I use it for both hard wired and wireless connections. I want to SSH, remote in, on port 22 to a small linux machine I have. I have a another linux machine that when I plug it into the combo unit it automatically opens up port 22 and I can access it from outside my LAN network. The port is not opened on the combo unit either. So I plugged in my other linux unit, set it up properly (from what I know) and can't SSH into it. I then opened the port up and still can't SSH into the new linux unit. It does not make sense to me how my first linux box can be accessed outside the network with no ports forwarded on my combo unit. Any advice on what I can do? Further, can I go to my local cox store and switch out my combo unit I received from them and get just a modem with no wifi? Thanks!2.4KViews0likes4CommentsCisco DPC3825 and iPHONE 4S can only log onto wifi with Out of the box SSID and Password
