How to access Webstar DPC2100R2 hidden pages If you have Time Warner Cable and perhaps other cable operators as well that use Webstar DPC 2100 modems, and you happen to have one of these modems, no doubt you've become frustrated when you go to check the modem log if troubleshooting a connection issue, only to be greeted with the web page that says that this feature is not enabled. You however can still get at the information you're looking for. I don't understand why these diagnostics pages have to be hidden from us, especially when other modems show us the info we want with no issues.

But here are the steps to gain access to the other diagnostics pages on a webstar DPC2100 modem. First, go to and change the access level from 1 to 2. Enter the password of W2402 and hit submit. You should then be able to access the signal and logs pages with no issues. I've however noticed that the access level after maybe about a minute or so reverts back to level 1, so if while browsing the page, if it refreshes and it suddenly says this feature is unavailable again, just repeat the steps above. Like I said, I wish I knew why so much effort is made to keep us from truly seeing what's wrong with our connections. There's no harm in viewing this info ya know.

So there's my hopefully useful tip for today. Code: Sat Jun 09 18: Critical (3) DHCP WARNING - Non-critical field invalid in response.

I have a Cisco WebSTAR DPC2100R2. It is currently running software version v2.0.2r1256-060303 The newest revision of the firmware I have.

BTW, when the connection was dropped I couldn't ping google.com, but the wireless didn't show any indication that it didn't have a connection with the Internet unless I let the situation set for several minutes, or I was busy writing something and the webpage disappeared.

As soon as I configured my new Linksys E2500 than this appeared. Code: Mon Jun 11 02: Critical (3) Started Unicast Maintenance Ranging - No Response received -.and the problem continues. So does the problem with a lack of range.

Just like the TP wireless, setting 10 feet from the wireless most of my neighbors, 5 to 15 times farther away, have stronger signals being picked up by the wireless than mine. When I surf from my bedroom, 60 feet away, it gets even worse, but the neighbors signals are still strong. A couple of them have no clue about security and run their wireless open. All of them are using Windows. I also discovered that the Cisco DCP2100R2 cable modem TW gave me is DOCSIS 2.0, which means it doesn't support IPv6. So, I am going to get a Motorola SB6120 cable modem that uses DOCSIS 3.0, which supports IPv6.

Ah, those are just DOCSIS error messages from the modem's WAN side and have almost no relationship to connection quality. My log is filled with them, yet I never have issues with poor connectivity. To fight your neighbor's wireless, investigate getting a wi-fi access point that you can reflash with DD-WRT.

This will allow you to crank up your transmission power. Alternatively, if you can get your equipment up to the 5 GHz range, the neighbor collisions should go away, because there are so many more channels (and fewer, for now, devices). Finally.spend the extra $10 for the SB6141. The 6121 bonds only four downstream channels. The 6141 bonds eight channels; you'll see less variability in speeds when you have more channels to spread across.

And if you're lucky, TW has probably screwed something up somewhere, and you'll get an 'accidental' speed boost. I know plenty of Comcast customers who've noticed that. I plan to (finally) buy my own cable modem for exactly this reason. Let's ensure we're aren't accidentally mixing things up here. I'm assuming you're using two separate devices: one cable modem and one wireless router. Is that right?

If so, then any conversation about DOCSIS relates only to the cable modem. DOCSIS defines the standards used for modulating digital signals over television channels and the methods for bonding channels together. I am unaware of any cable modems that run user-customizable firmware. Conversations about DD-WRT relate to flashing an open-source firmware onto a wireless router or access point. This often adds new features like the ability to fine-tune and increase transmission power.

But it won't add stuff the hardware can't do: for example, DD-WRT won't magically convert an 802.11b access point into 802. Yogi Bhajan The Mind Pdf To Jpg there. 11n. So, assuming that you indeed do have separate devices, this provides the opportunity to optimize each one (for this reason, I would never purchase a combined cable modem + wireless router). Choose a future-proof cable modem like the Motorola SB6141 or the Linksys DPC3008 that are capable of bonding eight channels.

And choose a wireless access point or router that's listed in the DD-WRT database. I've been having a problem with low power from my wireless even though I have it set for high power. The WR1043ND and now the Linksys E2500 are exhibiting the same problem: I'm ten feet away from my wireless but.you'll notice that my wireless has the lowest strength. So, the new wireless router didn't help.

I'm assuming that the weakness lay with the cable modem.No, there's no signal strength relationship between your cable modem and your wireless router. Typcial power levels from a to a cable modem range from -1.5 to +0.1 dBmV. The 64-QAM or 256-QAM modulated signal is fully converted to standard Ethernet inside your cable modem.

This is completely orthogonal to your wireless signal strength issue. Looking at the list, I see that you're running on channel 11 (frequency 2462 MHz) and so is 'belkin.fec.' Most everyone else is on channel 1 (frequency 2412 MHz); 'GarberNetgear' is on channel 3 (frequency 2422 MHz) and also helpfully letting me know who they are and what kind of gear they have! But I digress.

First thing I'd suggest is changing your channel. Park yourself on channel 7 (frequency 2442 MHz) -- that gives three free channels on both sides of you. Wireless channels actually overlap, and this is a common cause of performance problems.

What tool did you use to generate that list? My iwlist wlan0 scan looks very different.

Let's try an alternate measurement method. What is the output of. However, I never see the 5GHz ('N') setting. The only one presented is a 'G' connection. So, I renamed the 5GHz one 'GreyGeek5N' and the 2GHz to 'GreyGeek2G'.

The GreyGeek2G shows up in the ESSID map and I can choose it and set it up, but I never saw the GreyGeek5N. So, I don't understand how to take advantage of the 'dual band' capability that is supposed to make your connection speed more consistent and a closer match to your rated bandwidth.Well, it takes two to taNgo. To get 802.11n working, both your access point and your wireless NIC need to support it. It appears that your wireless NIC lacks this capability.

We can check. Looking at the list, I see that you're running on channel 11 (frequency 2462 MHz) and so is 'belkin.fec.' Most everyone else is on channel 1 (frequency 2412 MHz); 'GarberNetgear' is on channel 3 (frequency 2422 MHz) and also helpfully letting me know who they are and what kind of gear they have!

I'm beginning to think my E2500 is defective.

I have a Cisco WebSTAR DPC2100R2. It is currently running software version v2.0.2r1256-060303 The newest revision of the firmware I have documentation on is dpc2100R2-v202r1256-100324as The new firmware is needed for this modem because of a security gap that allows malicious websites to reconfigure, monitor, and/or disable the modem activity. According to the documentation I have found, the firmware cannot be updated by the end user (myself), and that the update must be requested and sent from the ISP (Time Warner). This is my own purchased modem, and not a leased modem. This modem was commonly used by TWC around 2010 based on my research. My question is if TWC is still able to send the update to my modem. You can find documentation regarding the security gaps for my modem at the following link: Any help advice would be greatly appreciated.

I just recently bought this modem and would like to keep using it as long as possible without security concerns. Did you run the test and does it show your modem is vulnerable?

The latest firmware is not the best or the correct firmware. The modem is also an obsolete DOCSIS 2 one and will need to be replaced. It's only good for a single channel, I had to get rid of mine due to the channel I'd end up on getting overly congested and interfered with from FM radio causing internet speeds constantly below 4Mbps The security problem was noted in 2010 and probably fixed back then. This is why you run your own router with a different password other than the default in it. I ran the test and it showed that the modem is still vulnerable. I haven't had any issues with my modem for the two months or since I have started using it. I have my own router with a password I created, but my question is about my modem.

There isn't an option to change the password on the modem (that I am aware of), and even if the password on the modem is changed, it is still vulnerable to malicious scripts without the most current update. The speed of the modem is fine for me, as I am only paying for 3Mbps, and I get that consistently.

At 3 down You're probably ok. Issue here was trying to run 15/1 or 20/2 thru one of them and I was only getting an average around 6Mbps.

Because we have bad qam channels. Since yours is provisioned for 3.0/1 you'll probably not see speed loss unless your local system gets overloaded. It was a TWC lease and I now have a sb6141, don't think i have a printout on the version It won't support IPv6 which will be mandatory in a couple years. As long as you're using your own router with a custom login/password, and not the default, you're probably safe. You can't, firmware upgrades comes from the cable company.

Yes, having a router solves most of the problem, with out it, a direct connected computer would be vulnerable. Problem is, that's an obsolete modem and TWC's not going to replace it and probably give you a hard time as you own it. They want everyone to go to DOCSIS 3 as well as all other cable companies. The coam approved modem list is outdated as well.

TWC quit issuing that model a couple years ago in most cities. Google 'cable modem firmware upgrade' for the horror stories.
