Cisco :: 3550T Catalyst Switches Shows Cable Not Connected
Apr 12, 2012
Device: Cisco 3550T Catalyst ...Tested working all ports Configured Speed/Duplex both manually and set to auto with same result Problem: No connection when connected to specific Motherboard/Lan chipset that is using Realtek PCIe GBE Family controller (NIC)
Motherboard1:When connected to the 3550T the LED is amber for maybe a minute then goes off
Motherboard2:When connected to the 3550T the LED is Green but Motherboard Nic is amber.In windows under adapter settings, Local Area Connection Both Show red X
The ports are only configured with
Switchport access
No other filters or access list? I have tried on multiple Cisco Switches 2950T, 3500 and 3550T with same result. what odd is these pc's can plug into a Netgear or ActionTec(Verizon) type of switch and work fine. Is there some command I need to apply to those ports to make it work with these GBE controllers. Or How do I get these Gigabyte Mobo(NiC) to work on Cisco Switches?
One of our office´s PC is connected to the network and shows 2 networks, but we have only one modem and one router....and no internet access only in that computer. I had restarted, disconnected, shut down and nothing.....what can I do? I also connected it to another cable form other computer working correctly and didn´t work.
I have connected 2 SG500x switches using an SFP-H10GB-CU1M SFP+ Copper Cable module. Since the port shows as a 10G port, I would expect the speed to show as 10G as well. However, it shows as "Unknown". This doesn't leave me with confidence that it is being recognized properly. The link is working properly, but I haven't run tests to verify if I'm getting full 10G throughput or not. Shouldn't it show 10G as the link speed?
I have 2 Cisco Catalyst 6509 switches connected directly using direct point to point link.The OSPF is configured for point - point link.The currently the interface is down administratively.I will unshut the port . After that i would like to know how much time will it take for the ospf to establish the neighbour relation.
I am troubleshooting a fiber connectivity issue.Now I have two switches, one is 3750, and another is small biz 300 series switch. Both switch has a single mode smf gbic. Now I have two swtiches face to face and connect with a single mode cable. Do you think if I would get a link light on? Both ports are no shutdown.
Are there any best practices for preventative maintenance on Catalyst Chassis switches. Looking to build a PMI schedule for a customer. Or is there evidence not to perform it at all. Things like re-seating line cards, cleaning fan exhausts, etc.
I have a Windows 7 Laptop which has got a red X on the connectivity icon even when connected, and this since april. Now, I don't have any idea of what caused it. I have Tunngle installed, but i don't think that's the problem. I also have updated my internet drivers, but without success. In the network boards i also have a weird second wireless connection which is called "Microsoft Virtual WiFi Miniport Adapter #6"
The route is connected to that. Wirelessly, there are two laptops and sometimes an iPad and sometimes a Wii. Verizon DSL. I barely use my laptop during the week, but did notice some connection issues maybe Thursday and Friday nights. All day yesterday and today, as well. I will have a connection for maybe 5 minutes and then get errors loading webpages (and/or videos stopped). I will repair the connection and it will say everything is fine but it will not work, repair again or disconnect/reconnect(sometimes, several times) and then it works for 5 minutes or 20 minutes before the same thing happens. The other laptop is having the same problems. What I have tried so far: restarting the PC, both laptops, the router, and the modem. Resetting the modem. I have not moved any furniture or anything that would cause interference. I am worried because I have been trying to make more money and started at this site called Treasure Trooper which seemed okay-surveys and the like. There were a few pay-to-download things I downloaded but did not run. Avira found a trojan and I deleted it (not sure if the two are related, but I can not think of anything else I have downloaded or installed in the past month or so).The old PC is off; the Wii is on but probably only maintains a small connection. The iPad and other laptop are not mine, but if either is on, they probably have little to no activity right now since the user is away.
My Acer One Aspire wireless connection shows connected but I cant get any Firefox browser to work.
I have a D-link DIR-825 router and it has worked every time except today. I havent used my Netbook very much at home though, maybe a few times a year as I usually take it with me on trips.
I attempted to narrow down the problem. I called D-link as my router was still under warranty. They advised clearing all my old connections and rebooting but I got the same problem. I told them my Sony PS3 works, so they suggested I contact Acer as they think it is not the router. My direct hardwire connection also works.
I then took my Netbook to Best Buy and it worked there. The guy said they can pay a visit to my house as it is probably interference of some sort. This will cost $100. Why would my PS3 work if it was interference? Maybe it�s the proximity of my Netbook to something, but I tried it near my PS3 and it still had the same problem.
Id rather try to solve the problem myself first. I havent changed anything except a modem and Windows 7 updates.
as gone all of a sudden. Checked cables, restarted both router and PC, and even rang provider with questions.. Router seems to be working fine as laptop and iphone both got internet access with the same router. The Local area connection icon showed limited on no connectivity snd so the provider renewed the IP manually and local area connection says its connected now but there is no internet access.. They suggest it could be something to do with firewall or something else blocking it but as far as I am concerned I did not make any changes to the pc the night before when it was actually proper connected.. The desktop pc is running windows XP and I tried downloading ethernet controller driver from the web and upgrading it but it did not improve the situation.
I see some other threads about this same thing but I wanted to start my own to keep track if what I did. I know zilch about computers.I have an ACER I got less than a month ago. I have Verizon mifi. Windows 7My comptuer says I am connected but it says no internet access. The wifi works fine on my old netbook though. I keep getting error 105 Unable to resolve the server's DNS address. What do I do?
On rv110w, I have 4 vlans. vlan3 feeds a dumb switch and a Wireless AP. When looking at router DHCP leases, it shows devices connected that are not connected. Kinda like it doesn't refresh the list. Set to 50 leases. Questions: Is this normal? How often should it refresh? Is the DHCP time put in as minutes???
My WAP4410N is configured with 4 seperate SSIDs. Two of the SSID status are showing "Enabled". The other 2 are shown as "Connected". The one that are showing as Enabled are not receiving any packets. Devices connected to the SSID that shows "Enabled" are unable to connect to the network. Any one else encountered similar issues before? This issue just surfaced few hours ago. The device has been using for around 2-3 years with minimal issues.
I am connected wirelessly on my laptop to my DIR-655 (D-Link) router. There is something weird going on to me in which is shows I am connected to two networks, one my home network clearly identified. The other one a "public network" listed as unidentified, all on one wireless connection. I run Windows 7 SP 1 32-bit. I would like somehow to merge or remove the second one from the listing.
My computer (running windows XP and connected to the internet with a D Link USB adapter) refuses to load any webpages: despite showing full signal strength and connection in both the D Link settings and the windows XP wireless panel.I am able to ping websites and other computers in the house (all of which are able to access the internet) but no pages load in any browser I try.
I'm trying to get a wireless router working for friends. I got it to work yesterday, but now it is no longer working. [code] If I connect my computer to the HAG, it, of course, works fine.Yesterday, I hit the reset button on the back of the conitech router (because they didn't have the password) and went through the setup wizard, connecting my HAG to the WAN port on the router and it worked fine, both connecting via wireless and with a cable to one of the LAN ports on the router.Today it is no longer working. Both wireless and LAN show it is connected but I can't access the internet.
when I hover my mouse over my signal bars it says I am connected to a network named 'home-9C78' but when I click to bring up my list of available networks, it says I am connected to a network named 'Reshiram' Reshiram is the name of my network and there is NO 'home-9C78' ANYWHERE in the list!!! I don't know where my computer gets this home-9C78!!! and I NEVER ever connected to a network with that name!!! it is supposed to be 'Reshiram
my neighbor is having a problem with her computer, its an HP touch smart [not sure of model] every other computer in her household works [1x wired 1x wireless].
the computer in question has had repeated problems and various hardware issues and has been sent out for repair on more than one occasion all for non software related issues, i take care of software issues and diagnose hardware problems and i have done so without a hitch until now.
when the problem first started happening i would do a system restore to a point were it was working, but that does not seem to be working anymore
i have tried disabling firewalls [she uses AVG internet security edition which is on all of her computers], windows firewall, disabling and re-enabling network drivers, updating drivers, installing different and previous versions of browsers
My wireless connection shoes connected but no internet access. when i connect directly to the modem to computer internet is ok. i am using linksys wrt400n route
I have a Dell Vostro 1500 and I have AT&T wireless internet in my house. My other computers and Roku connect with no problem, but mine even though it says it is connected, is not connected. I have Windows XP the other computer is Vista and the desktop is also XP. Even AT&T came over the house and said something is wrong with the computer.
I have an EA 4500. Tonight I was trying to see what devices were connected. The window shows 0 devices connected, although about 20 devices are connected and working. When I click on "Devices Connected", I get the spinning wheel, and after multiple attempts by the application to list devices, I receive a message that the application does not work. I have the latest firmware installed. This is a recent issue. I have not made any changes to network configuration, nor to any of the devices that all have internet access. I will note that I did not set up a separate SSID for each band. But that did not seem to be an issue in previous months. I also cannot access the router ui from my windows 7 desktop. I can access the abbreviated ui through my Android phone. I tried connecting through smart wi-fi and by ip of the router. I just get the endless spinning circle of dots. I am running Windows 7 all up to date. All drivers are up to date.
I am trying to find out what devices are connected to my router. I have had some illegal downloading from my IP address but it has not been done from my computer. It is showing in Cisco Connect that I have 15 devices connected, I should have no more than 6 devices connected so trying to figure out who is connected on my computer.
I have been using Dell Vostro-1320 laptop with Windows XP. It was running good. Recently I have installed the McAfee Internet Security software. But now I do not have internet access through this laptop although the network icon shows "connected". I have tried all the advice/solutions for such type of problem by doing Firewall off/on and changing adapter & network setting. I also updated all the drivers. But nothing works. It is notable that my other desktop is working properly in spite of installing this software.
show cdp neighbors command shows two devices connected through the same local port?I have a Cisco 3560 that when I issue the "show cdp neighbors" command I get the following results: [code]
the question is why is this showing that Gig0/3 is being used twice to connect to two different devices. I have verified there is no hub connected to this port and in fact Switch3 is not connected to Switch1 at all yet it still shows up in the CDP table.
I have cleared the CDP table on every device at this location and still get the same results.
I am having Inspiron N4010 for almost an year now. I have had many troubles with this but never with internet connectivity. Last week I saw myself not being able to be connected to internet through wireless or wired network while everybody else was connected and surfing. I just thought it to be a small problem and the problem seemed resolved that very day itself on its own.
But today this computer has simply failed to get connected. it does get connected, open a page or two and then again refuses to connect. On the problem diagnoses from network sharing center, it was showing that the websites are not responding, then it started showing that DNS server was not responding while all my setting are correctly configured. I pinged gateway and it responds but on pinging some website there is no response at all. It s a problem with my laptop only as everybody else are using internet very well. I am using internet through my WiFi enabled cell phone using the same connection and router that i use for my laptop. I need an urgent solutions as I have to meet some deadlines regarding assignments.
I have a Lynksys WRT600N. I had DD-WRT on it and it was working great for about a year. One day I changed some minor settings like wireless signal type, reboot it and it's gone. I can not access it from my computer. The network adapter shows "cable unplugged". The lights on the front come on, but I can't get anywhere with it.
I've done all the resets I know how to do, including the 30/30/30 and leaving it unplugged for a few months.
I have a Dell Studio 1737 running Windows 7 64 bit. I turned it on today and it automatically connected to my home network as usual and when I hover over the network icon it says there is Internet Access but when I open Firefox it can not connect to any websites. When I run the automatic troubleshooter, it does not detect any problems with the connectivity.
I ran ipconfig /all and this is what came up:

I've got an apple Airport Express and have managed to set it into my network. Airplay works on both Itunes and my phone. However after 10-15minutes the Airplay drops out and the network map shows that the airport express is 'offline'. however the airport express LED remains showing it still have connection to the network. The only way to get it back is to reset the AE. The apple forum has lots of people stating the same problem with WAG120n routers.
-Router Firmware V 1.00.16 -Airport Express firmware version 7.6.1 -windows Vista
