Can't access WR80G. Sniffers detect it ESSID, signal, etc. Leds green. bt doesn't comunicate.

Can't access WR80G. Sniffers detect it ESSID, signal, etc. Leds green. But doesn't comunicate. I could save ethercap or etherreal captions and send them attached. I had reflashed it some times. I had recovery from broken state by reflashing it first whith 4.03 firmware, later with 6.14 and whit freifunk in the last instance. It had bricked before, after my trying to recover deffault settings. But now, I select dhcp in wan config. (freifunk) since I did think to use it like a second node in a two moto's net. I aplied changes without change the lan addres previously. I think that could have been an error. I have reseted it some times since then.

    Thanks you both for trying, only a few hours after my asking.

    I know manuals. I had handled default IP addresses. My PC has actually and is conected to another identical router managing several pc's routing.

    I suspect my speech is not clear enough as I'm not english speaker but reader.

    If it's not an abuse I could upload files from etherreal sniffing when pc is cable conected to the unaccesible router. If you or anymore can analyse.

    Any activities are detected between the own router's MAC addresses but the PC eth adapter MAC is absent all over those captions.

    When attempting a dhcp conections to router, the result is limited or null conectivity and a 169.x.x.x ip address.

    I'm Sorry. I don't understand this ranking sistem, but no one is best solution since no one solve my trouble. It is more complicated than IP-ing...

    No. I don't know how to ping mi pc card from my own pc.

    It's posssible?
    what could thatt be usable to?

    Router doesn't respond ping.

    But snifer software can detect some traffic. Reports show the respective router's MAC's.

    Smooth_Gecko,Do you know how to understand that reports. They can be shown in plain text.. Thanks you

    P.S. My ethernet card isn't gone.
    I used it to sniff whith etereal connecting pc-router by cable ports 1,2,3,4 and wan port. O.K.?

  • Anonymous Aug 07, 2007

    Nothing have hapened. both Genius2k4 and Smooth_Gecko solutions asumes I can communicate with router using an IP address.
    I suspect its possible sending a firmware to MAC address, using fttp or another protocol.
    Router is not responding pings.

    I did ping -t in a dos window for many hours without sucess. Suddenly it begin to respond. I had reflashed by using another DOS window, while it was responding, as I had learn previously, and Voila! it is working now.

    Thank you guys for your helping me.

Try setting your PC to DHCP in your network connection settings, plug in ethernet cable & reboot it.

    The authentification is where I would look next. I chased a limited or no connectivity problem for a while the other day, and it turned out to be in there.
    Can you ping the ethernet card and the router?

  • Anonymous Aug 03, 2007

    Can you ping the card in the PC, from the PC?
    I am getting the feeling your ethernet card is gone.
    You should be able to ping your card and the router as long as you have a cable plugged in.

    Quote "My PC has actually"
    From "run" on the main menu, just type "cmd" to get a console.
    Type "ping"
    and hit enter.

    Then try pinging your routers IP address.
    Until you can ping the router reliably, nothing will work.

    Have you done what Genius2k4 suggested?

If you have set it to dhcp on wan only then your local pcs will not be issued an IP address unless dhcp over lan is enable you could try setting a static ip on your local pc but it has to be in the same range as your router, your routers default IP address is so set your pcs ip to and of course try talking to your router via the ethernet cable not just wireless.

How do i locate audio and video spy devices someone has planted in my home?

There are little receivers you can purchase that are wide banded an as you walk around the house holding the the receiver near objects it will buzz. Telling you a radio signal is in that area. You can make one very cheaply. If you search ebay, youtube you will find devices people have used. Some are called sniffers, locators, etc.

Often LEDs have difference electrical tolerances and are not compatible with other systems without special adapters to balance conductivity etc.

Flashing lights in the front of ibisurfer

vid shows nothing leds are to tell u something not just diagnostic ie most pcs / laptops have a light that flashes a lot telling u when its comunicating with the hard disc drive thats perfectly fine does the system run ? whats happening ? is it just the led worrying you with no obvious symptums we need info to help whats wrong what is it

ie make acer
model aspire 1283
seriels etc every bit of writeing on it

that tells us what were dealing with

then we need the most informitive description of the problem ie

system boots to bios but when you try to load windows it says (xxxxxx) there is a led on the front that used to show green but now just stays red

that tells us a heck of a lot more then you would think

once we know exactly what were fixing and exactly what its doing that it shouldnt be doing then we can help

When I plug in the router, it doesn't do the checks all 3 LEDs are on. I also can't access the router settings nor the network i set up using the router

Without knowing the brand and model, I would say this router is defective. If the LEDS are not cycling through and remaining solid lit, this is a good indicator of a major problem. Try pressing and holding in the reset button (usually located on the back or bottom) for at least 30 secs. Some routers require disconnecting from power, holding in the same button and then restoring power and then releasing the button once the LEDS cycle. If the resaults are the same and the LEDS "freeze", then the router is likely defective and not repairable.

I cannot pair my nokia e63 with genius bt-03i. seems the phone can't sense the signal from the headset or either the headset is not transmitting bluetooth signal

Make sure the blue-tooth headset is charged

Make sure the phone is set to automatically detect new blue-tooth device.

On the headset, press the power key for five seconds until the RED light blinks quickly.

Phone should detect headset within 10 - 30 seconds. It should eventually say BT-03A then ask for aOnce it does, type 0000 into the phone when it asked for a device ID.

I have a Sitecom WL330 wireless repeater

Hi I'm having the exact same problem with a Sitecom WL330 and a BT business hub. Just get unidentified network when trying to connect. Did you resolve your problem? and if so how?


Connecting cell phone and Jabra

Check that both devices are BT enabled and in pairing mode -ie, leds blinking-. If one of the device is not in pairing mode, it is normal that the process fails.

If you experience the same problem on other phones with your Jabra BCE-250 -same as mine-, you might think of getting it checked first.

LED Display gives you your display visual alerts, signal strength, and operation mode. Here is an attached link for the manual.....
But to answer your question here is what the difference between the green light and the red light are:
1. X-Band Signal Indicator—A green LED lights and blinks to
indicate the presence of an X-band radar signal. The blink rate
increases as the radar source gets closer. A distinct audio alert is
also heard.
2. K-Band Indicator— An amber (orange) LED lights and blinks to
indicate the presence of a K-band radar. The blink rate increases as
the radar source gets closer. A distinct audio alert is also heard.
3. Ka-SuperWideband Signal Indicator— A yellow LED lights and
blinks to indicate the presence of a Ka-SuperWideband radar
signal. The blink rate increases as the radar source gets closer. A
distinct audio alert is also heard.
4. Laser Signal Indicator— A red LED under L lights and blinks to
indicate the presence of a laser signal. A distinct audio alert is also
5. SWS Signal Indicator— When an early warning hazard or
informational signal is detected, the yellow SWS LED begins to
blink and the amber K-band LED lights. A distinct audio alert is
also heard.
6. Power-On Indicator— A green LED under P lights to indicate
power is being supplied to the unit and the unit is turned on.
7. LED Signal Strength Meter—Four LEDs give an accurate visual
indication of the strength of radar or laser signals.
8. City Mode Indicator—A green LED under C lights to indicate
that you selected City Mode.
9. Auto Mute Indicator— A red LED under M lights to indicate that
you selected the Auto Mute feature.
