Troubleshooting page ea6900 - multiple LAN connections

I have EA6900, guest access enabled - when I log in remotely and look at troubleshooting page, I see several connections (two subnets, mine and guest) - some are listed as wireless and some are LAN. I see more than 5 LAN connections.
Since the router only have 4 ethernet ports on it, how can I have more than 5 LAN connections? Am I mis-understanding the table on the troubleshooting page?
Also, one of the LAN connections is 0:0:0:0 - not sure I understand that one.
This is at a seeeasonal rental property, I hid the router to keep guests from monkeying with it. They should only have guest access via wireless.
Can someone provide a better description of the troubleshooting page than the one-sentence blurb that comes with the router's user guide???
Thanks

I will say that I believe I've seen wireless devices displayed in this list as a LAN connection. In any case the IP Address of the device would show as the Guest subnet.
Yeah I can confirm what chadster said as well. I see wrongly labeled connections on my 6900 too. It works pretty good as a home based router but isn't always the best when you try to get too tricky.

Lan connectivity Issue on autonomous AP with throttles

          Hello,
I encounter a strange problem on several AP 1242 in version 12.4(25d)JA1 of a customer :
He has 10 autonomous AP covering a factory and is using them for laptop connectivity and TOIP with mainly 7921 Cisco Wifi Phones.
The phones are configured to use only 802.11a.
The APs loose LAN connectivity randomly and therefore the clients don't work anymore.
The AP are connected on a 2960 and a 3560 wich are in turn connected on a 3750 wich route the trafic.
After checking spanning-tree no loops are present.
When I check the counters on the AP involved I see the "trhottles" and "ignored" counters incrementing on the fa0 link of the AP impacted wich mean I think it can't handle the incoming traffic. This incoming traffic seems not to be too big however. I can see drops on the switch interface connecting the AP.
There is a lot of roaming on the AP due to people walking in the factory with their wifi phones.
Here is a view of the fa0 counters :
AP1242-LOGIST#sh int fa0

Does someone ever experienced a similar problem ?
When I shut radio interfaces they're is no more problems on the LAN. Can this be an overlapping coverage issue ?
Can someone please give me advices on how to troubleshoot this issue ?
Thank you in advance as I'm a bit stuck.
Best Regards,

     Hi Scott,
Thanks for your reply.
Do you think this can be the origin of the issue my customer encounters or is it only to be standard ? As this change will have to be made on all clients, if there is a chance it solves the problem I will do it ASAP, if not I will delay it in a less busy period :-)
Can the constant roaming associations and dissasociations overload the AP and make it stop responding on the LAN or is it only a throuhput problem ?
Thanks in advance for your answer.
Best Regards,

Error Code 10 Intel 82579LM LAN connection on Portege R830-13C

After recent Windows 7 32 Bit update, the LAN connection is failing to start (Code 10) under device manager
"This device cannot start. (Code 10)"
I have tried uninstalling drivers / rolling back / and installing the following files from Toshiba support pages, but does not resolve the issue.
- lan-20110330164846
- fareg-20110331130330
How do I get Intel 82579LM Gigabit Network Connection on Portege 830 -13C to work?
(wireless is fine)

Hi
Error Code 10 is generated when Device Manager can't start the hardware device and usually its caused by outdated or corrupted drivers.
Therefore I think that driver installation should help to sort out this issue.
I would recommend doing this:
- Go to device manager and uninstall the LAN driver
- Reboot the notebook but dont install the driver
- Install the CCleaner and clean the registry
- Reboot the notebook once again
- Then go to device manager, choose the LAN card (Ethernet controller) and install the downloaded driver
As option I would recommend testing the LAN driver from Intel page.

Multiple WLAN connections

Does anyone know of a way to get my PODCAST and Email applications to use multiple WLAN connections?
I spend most of my day in one of two places, each with a different WLAN, and I'd the phone to have the sense to change WLAN connection as they become available.
Thanks for your time.

Depends, on what your phone is.
If you're using an N97 or a 5800, or anything running on s60v5 for that matter, Go to Menu>Settings>Connectivity>Wireless LAN>Options>Settings>Show WLAN availability. Then you can also set how often it will set to scan for WLAN connections. This would allow the phone to scan for WLAN hotspots around you immediately. Be warned however that this will drain your battery faster.
On an s60v3 phone, I am not very familiar but from what I know its in Menu>Tools>Connectivity>Wireless LAN>Options>Settings>Show WLAn availability.

Hi,
Actually we have UCS 6248 fabric interconnect - first twelve ports are enabled and same in Cisco UCS Manager.
But when more port will be active by expansion module then UCSM can manage that too or need any other licence for UCSM too?

Wifi connection drops but LAN connection is fine

A strange one.
I have both WiFi and LAN connections to my HH3 for different computers
The LAN connection is always fine - good speed, no drop-outs, etc
The WiFi connection however is a nightmare. It works for a few hours and then the computer drops the internet connection.
It is not the WiFi connection to the HH3 as I can still get to the HH3 web page but any internet address gets a "DNS not found" error.
In this state, the LAN connection still works fine. I can browse the Internet fine just not from a WiFi connection.
The only solution is to reset the HH3 fully (a disconnect/reconnect of the internet connection doesn't help)
Any ideas?
Chris

Hi there,
It sounds like you need to change the wireless channel on your HH3.
If you're on Windows then you're going to need inssider 2 or if you're using a Mac, then you'll need to download istumbler
Download whichever one of those is appropriate to your OS and do a scan for wireless networks close to you and you will be able to see which networks are operating on which channels and change to a less congested channel, if need be
I hope this info helps

Local only connection on multiple wirelesss connections

I've seen several posts to this affect, but no resolutions. I have a WRT110, one wired connection which works fine and multiple wireless connections. Only one wireless connection can be active at a time. If connection A is active, and connection B comes on-line, connection B takes the internet connection and connection A is left as Local Access Only (but still connected to the router). After connection B goes off-line, connection A can reestablish internet connectivity after a short period of time.
Any thoughts?

I would suggest you to readjust the wireless settings of the router...On the Linksys Setup Page try doing the following settings.
Under the Wireless tab..
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz
Under Advance Wireless tab..
- Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304.
Now,try to connect both the laptop...

LAN connection not working/Ethernet controller driver missing

I got a new hard drive and installed a clean copy of windows 7 on it. After dealing with a few problems I finally had it up and running. I transferred via usb and installed drivers from http://support.hp.com/us-en/drivers/selfservice/HP-Pavilion-500-Desktop-PC-series/7779690/model/8154137#Z7_3054ICK0KGTE30AQO5O3KA30R1. Every thing is working except for my LAN connection. I can connect to wifi however. In device manager I have a ! next to ethernet controller. Had ! on a bunch more before installing other drivers. In network adapter settings there is no listed Local Area Connection. What do I need to get my Lan connection working again?

Hi: The support page for your model indicates you need this ethernet driver... This package provides the Realtek PCIe GBE Family Controller Driver for supported models running a supported operating system. File name: sp71102.exe You have to manually install this driver. Run the file and then go to the device manager. Click on the ethernet controller needing drivers. Click on the driver tab. Click on Update driver. Select the Browse my computer for driver software option and browse to the driver folder that was created when you ran the file. That folder should be located in C:\SWSetup\sp71102. Make sure the Include Subfolders box is checked, and the driver should install.

BT HUB5 Drops wireless & LAN connections 01/01/201...

Hello
Wireless and LAN connections has been working perfectly fine when i first signed up to the complete BT package (broadband,phone,TV) in September 2014. During the beginning of January 2015 to now February 11/02/2015 my wireless connection drops out in the morning and evening multiple times 5am-7am at least 3 times in the morning and at least 5 times at night 6-12. This drop out also affects LAN connections even though the BT HUB 5 is still lit blue, there is no fault light, once or twice I seen the fault light.
I cannot not browse the internet and use Netflix’s etc because the wireless connection drops out regularly. I have spoken to BT’s Global Service Desk who reported there is a problem, however a UK call centre engineer confirms there is no problem and the issue lies with ‘Interference’ and their excuse was it was probably conflicting with other wireless devices which is total nonsense.
I have checked with my neighbours and they have not bought any new devices or changed anything which would conflict with wireless connections, including kitchen appliances. I also have followed BT advise and switch everything off and on again, reset the router back to default, they have reset their end, changed the wireless channel etc. still get the same issues.
Everything has been working fine up until January so something has changed on BT’s end to cause regular problems which affects LAN and Wireless connections. Many sources on the internet suggest firmware and line testing for faults like on their BT HUB5. BT suggest there are no problems and everything is working fine and they have no problems on their end. I’m still waiting for a solution from BT……?; an issue like this would have been resolved or never happened with SKY and Virgin fibre connections.
Please can someone help and adviise best practice to get my BT HUB5 working again properly or suggest what BT must do to pull there fingers out and take ownership of this issue. Many thanks.

Sorry to hijack someone else's thread but I seem to be experiencing exactly the same issue.
Service was installed around about Sept last year and has been fine until the last few weeks when the same wireless drops started to occur. I have no new equipment connected, but all devices experience the problem.
Having looked at my HH5 version, I'm on the same:
BT Home Hub 5 (Type A) | Software version 4.7.5.1.83.8.204 | Last updated 21/01/15
I noticed the update date of 21/1/15 which probably coincides with when the problem started, so I wondered if there might be a known issue with this software version?
Thanks

Hi,
I'm a bit of a technophobe but know what I'd like to acheive if possible. I do struggle trying to understand my computer and the BT facilities also.
However, If my comprehension skills tell me correctly, it may be possible for me to connect my desktop to my laptop.
The desktop does not have the all important component that allows wifi. It is connected to the router by USB. The laptop has the component and does receive wifi.
I want to connect them both! Can anyone help?
Happy Christmas! Geoff

It is possible to add a USB Wifi adapter to the desktop, and then enable Internet Connection Sharing, depending on which operating system you desktop has.
Its quite a hassle to get it going reliably, and it also means you desktop would have to be left on if your laptop needed the Internet.
A much better option is to change your router for one that has wireless, like a BT Home Hub, or similar device. I assume you are probably using one of the earlier Voyager USB modems like the Voyager 103?
You may be able to get one from BT if you re-contract.
You desktop will then connect to the new router using the LAN connection, and the laptop will use wireless.
USB connected routers are obsolete, and not supported these days.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

Bluescreen on disableing the Lan connection.

Good day!
My problem is the following. I was using the computer like always this morning, browsing the web, when suddenly i lost the connection. First i checked the page of the router (connection to it was fine), and it showed that there are no problems with online
connectivity. So i decided to test disabeling and reenableing the Lan adapter/connection. Upon disabeling it, the pc froze, and a bluescreen showed up.

What do i do if my internet is wep and i need it to be wpa2 because my ipod touch 4th gen connects to the internet but when i click on safari or itunes it says safari cannot open the page because its not connected to the internet

what do i do if my internet is wep and i need it to be wpa2 because my ipod touch 4th gen connects to the internet but when i click on safari or itunes it says safari cannot open the page because its not connected to the internet. i have contacted apple support and they said to change from wep to wpa2 but when i change it to wpa2 and type in password and connect on my laptop it says the saved setting on this computer for the network do not match the require ments of the network

My 2nd gen works fine with WPA2 and AES encryption.
You may need to go back and start over. Reset the router back to factory defaults, log on as the admin, set up security, DHCP, and make sure the IP address pool has enough IP addresses to lease to ALL of the computers/devices that will connect to that the router.
