How to access Webstar DPC2100R2 hidden pages

[GreyGeek]

Yup. That's the ONLY consolation in this whole situation, but my "advice" is getting poorer as time passes. That and my eyes have been the primary reason why I decided to retire as an Admin, so my advice wouldn't reflect poorly on the other admins and this site.

[SteveRiley]

True, but looking back at the mountain top I WAS on and realizing what the things are that I can no do well, or do at all, makes me sad at times.

Mind if I turn this around a bit? Have you considered people who've you possibly helped on the way to the tops of their own mountains? I'll bet the number is greater than you think.

[GreyGeek]

.... What we all were able/capable of doing when we were younger, isn't the same as what we can/will be able to do as we get older. .....

True, but looking back at the mountain top I WAS on and realizing what the things are that I can no do well, or do at all, makes me sad at times. One occasionally loses things in life and has to work to regain them, but one thing I never thought could be taken away from me was my near photographic memory and cognitive ability. But, I was wrong, and that loss is worse than any other thing or ability I've lost.

[Snowhog]

You, Snowhog, Dibl, oceanluver, Qqmike, OneLine and some others are real geeks. I've degrade to a tinkerer.

You overestimate our abilities (me thinks), and underestimate yours.

Us 'oldsters' are aging. Can't be stopped (well, yes, it can, but the result is final!). What we all were able/capable of doing when we were younger, isn't the same as what we can/will be able to do as we get older. Simple fact of life. Just don't let it get you overly 'down' my friend.

[SteveRiley]

Don't underestimate yourself, my friend. IIRC, you were the first one to really start digging into *buntu's IPv6 support and writing up what you were finding. There's absolutely nothing wrong with your approach: experiment, document, learn more, update what you documented. We've all learned from what you've posted the last couple weeks.

[GreyGeek]

Well, Steve, as I've stated many times before, if I didn't have access to Google I'd have NO memory at all. Pardon me a little whine, but one of the most frustrating things is having to look up stuff I've known for years, or worse, remembering it wrongly and making myself look like an idiot. Now, will you pass the cheese, please?

My handle is rapidly becoming a misnomer, as my exploration of IPv6 demonstrates. You, Snowhog, Dibl, oceanluver, Qqmike, OneLine and some others are real geeks. I've degrade to a tinkerer.

[SteveRiley]

Wireless can be confusing sometimes, because there are so many variables. Fortunately, we don't have to memorize any of it, since Wikipedia continually offers such valuable nuggets as this list of wi-fi channels and frequencies.

[GreyGeek]

My Network-Manager now shows this:

So, according to the info from the RealTek website info repeated below, I have an "n" connection using a 20MHz bandwidth, and my connection speed is 72.2 MBit/s.

Complete 802.11n solution for 2.4GHz band
72.2Mbps receive PHY rate and 72.2Mbps transmit PHY rate using 20MHz bandwidth

Steve, thanks for your help and clarifications. It's nice to have an expert around when you need him! 8)

Now all I have to do is clean up that cable connection outside, and then figure out how to get 10/10.

[SteveRiley]

mmm... I thought SixXS didn't need IPv6 routers? But, that's beside the point.

All IPv6 adapters will issue a neighbor discovery probe, even pseudo-adapters like those used for Teredo.

The wifi chip in this computer, the RTL8188CE, does not support the 5GHz band.

You found the answer. cfg80211 is reporting in dmesg what it's attempting to do. You can't rely on that report for a list of what the wireless adapter is capable of. For that, we use iwlist freq.

I set the regulatory domain to US with

sudo iw reg set US

and dmesg shows:

My Network-Manager reset and all of a sudden I am on channel 7 now, even though before I had set the E2500 to transmit on 7 in b/g, and rebooted the router and my Acer and it still came up in channel 1. But, the 5GHz band still does not show.

EDIT: Well, the mystery is over. From realtek's website:

Features

General 48-pin QFN CMOS MAC, Baseband PHY, and RF in a single chip for IEEE 802.11b/g/n compatible WLAN Complete 802.11n solution for 2.4GHz band 72.2Mbps receive PHY rate and 72.2Mbps transmit PHY rate using 20MHz bandwidth 150Mbps receive PHY rate and 150Mbps transmit PHY rate using 40MHz bandwidth Compatible with 802.11n specification Backward compatible with 802.11b/g devices while operating in 802.11n mode

The wifi chip in this computer, the RTL8188CE, does not support the 5GHz band.

But, I am going to leave the 5GHz band on for my wife's Acer One.

Now, on to other fish I must fry.

mmm... I thought SixXS didn't need IPv6 routers? But, that's beside the point.

It *appears* that cfg80211 does support 5GHz.

[GreyGeek]

Ah, the wireless chip in my Acer. I never thought about that. (My mind is going, Dave .... I can feel it....)

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

Well, it looks like it does. (b/g/n).

Now, the question is, does the rtl8192ce.ko driver support "n"?

Let's see what Google says...

[SteveRiley]

What's the wireless NIC in your PC? My suspicion is that your NIC doesn't support the 5 GHz band.

[GreyGeek]

No, there's no signal strength relationship between your cable modem and your wireless router. Typcial power levels from a CMTS 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.

Didn't know that.

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

sudo wpa_cli scan && sudo wpa_cli scan_results

I knew that channels overlapped and that more than one AP on the same channel can slow performance, so yesterday I tried 7, 8 and 11. That didn't improve the range. I also made some Cisco recommended changes to the values below, for both the 5GHz and the 2.4GHz bands, but they didn't help, so I returned them to the default values that are shown:

Beacon Interval: 100 (Default: 100, Milliseconds, Range: 20 - 65535)
DTIM Interval: 1 (Default: 3, Range: 1 - 255)
Fragmentation Threshold: 2346 (Default: 2346, Range: 256 - 2346)
RTS Threshold: 2346 (Default: 2347, Range: 0 - 2347)

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:

iwlist wlan0 freq

My Linksys E3500 wireless router is a dual band router and the setup screen has setting for both values. The 5GHz band, regardless of any settings I try, never creates an AP. The frequency listing generated is only for b/g

:~$ iwlist wlan0 freq
wlan0 13 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Current Frequency:2.412 GHz (Channel 1)

Here are my E2500 setup screens:
http://ubuntuone.com/17RdjNLKZc49cXEd0JgNrG
http://ubuntuone.com/1hufShs0G9eo6rPRggYX68

I've disabled the 2.4GHz band and tried to get a 5GHz ("n") connection but when I do that no AP appears. I'm beginning to think my E2500 is defective.

[SteveRiley]

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 CMTS 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.

sudo wpa_cli scan && sudo wpa_cli scan_results

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.
