Missing Network Adapter After Storm
May 29, 2012
Yesterday there was huge storm, and lightning smashed into nearby house. My computer was running and I turned it off just after that. Result of nearby lightning was that internet no longer worked afterwards.
Soon after I was able to connect on my laptop, (laptop was connected and turned on during storm too) but desktop was still unable to do so.
I noticed that in device manager there is missing network adapter in list. EVerything is connected as it should be, but ethernet port doesnt have any lights on. I believe there should be some small light on port as is on my laptop, but Im unsure.
how I could check whether my network card is ok? Or what could the problem be? I really hope its just software issue.

I have a Gateway Notebook Model ML6720 that has built-in Wireless. The PC was heavily infected by Virus and I had to re-install Vista Operating system. Now, it will not detect the Wireless Adapter. I went to the maufacturer's website on another computer and downloaded the driver and installed the driver on the laptop. However, it did not work. The blue "wireless" light on the laptop is "lit", however when I go to "Device Manager" and look at the Network Drives, it only shows the wired Ethernet option.

I had to Reinstall my windows Vista OS. My WNA was working prior to the OS reinstallation, so I am confused a bit. I have no idea how to reinstall drivers in order that dell gives me. I have downloaded the drivers from the Dell downloads section;however, I don't know what to do next. I tried to go to device manager and find network adapter, but it does not appear, only an "other" section with some ! marks next to them.

I have a two month old Inspiron 1525 laptop with a 1395 WLAN mini-card. My network adapter has disappeared from my computer. When I run the diagnostic on the Network, I get " computer does not have a network adapter installed and configured" What is going on Dell? I called the help desk and the condescending tech said that I had to pay 250.00! This is a two month old computer - Dell - stand behind your products!

I have a Sony Vaio VGNFW378D that runs with Windows Vista. Ever since I got this computer (about 2 yrs ago), I have had problems with it suddenly disconnecting from the internet. When this happens it could never detect any wireless networks and I would have to restart the computer to temporarily solve the problem. It usually happened after the computer was in hibernation.
Yesterday this happened again, only this time restarting the computer did not solve the problem. When I could not connect to a network I clicked on "Diagnose why Windows cannot find any additional networks" and it said "Install wireless networking hardware, and verify that the correct drivers are loaded".
I went onto the Sony website to download the Intel Wifi link 5100 AGN wireless LAN Driver and updates. The download was not successful and I received a message indicating that the latest updates of this driver were already installed in my computer.
Representatives at Sony only directed me to links that had steps to finding out what my problem was, which I followed with no success. Most of the steps included enabling the adapter in the device manager, uninstalling and reinstalling the driver, etc...I could not do any of these things because the driver does not appear in the device manager at all.

So the SG300's have STP on them and prevent network loops when other switches on the network also support STP too. However, if someone plugs in a non-managed switch that doesn't support STP with a network loop, is there anything within the SG300 switches to isolate and/or prevent that from happening?
(I currently have port mirroring turned on for one port and a network sniffer attached awaiting the incident to happen again).

I have a new PC with the Windows XP 64-bit OS. When I attempt to connect it to my home network, it doesn't see the network, and other computers can't see it. The network card driver is a 1394 Net Adapter. The driver appears to be working correctly, but it's not getting packets in or out. The setup seems to be missing the required Q0S Packet Adapter, but Windows won't let me install it.

Whenever I plug in an ethernet cord into the integrated ethernet port in my laptop, I do not get a connection and the "Local Area Connection" icon doesn't show up in the Network and Sharing Center or the Device Manager. When I do plug it in, the "Local Area Connection" icon shows up for a second saying it's unplugged and disappears. I have tried different ethernet cables as well as an ethernet adapter (which does show up in the Network and Sharing Center, but I still don't get a connection).
My laptop is a Dell Inspiron N2010, I'm running Windows 7 Home Premium 64bit, and my ethernet port "RealTek PCIe GBE Family Controller".

storm-control unicast level ?
storm-control action shutdown
What will be recommended level? or the threshold / pps ?I read through cisco website, and understand, however, just never apply before, what is the recommended level for ?in my network, we do have network ports connected to media server, just sharing video, song, etc for testing purpose, however not using PIM, but it work.

I`m connecting a client directly to a 3750, and giving them a public IP.
On the port I have set spanning-tree bodyguard enable
But I guess I should also set some storm control etc. What settings should I use for storm control?
The client has a 100Mbps internet connection running trough this port....

We're using ME-3600 and ME-3800 switches to create VPLS domains. Now to avoid L2 loop issues with 3rd parties connected to the multiple ME-3X00 switches and configured in the same VPLS domain, we would like to configure storm-control.
When checking the configuration manual about storm-control on ME-3X00 switches it mentiones: storm-control is configured on the physical interfaces and when it's triggered it will not only impact the physical interface buy also the EFP configured on it.
According to me this could mean two things:
When there's a storm on the physical port, the port wil be shutdown (it if this the action configured) and of course the EFP on that physical interface will be impacted too (logical consequence).When there's a storm on an EVC (EFP) configured on a physical interface, it will shutdown the entire physical port (if this is the action configure) and as a consequence all other EFP will be impacted too. Briefly: is the configured storm-control on an interface also triggered by storm-controls on an EFP? I suppose it would but like to have some confirmation.
configuration example
interface GigabitEthernet0/2
description TEST storm-control
switchport trunk allowed vlan none
[Code].....

There is a port on 3560E, facing POP, this port is in the dedicated vlan, that is terminated on 7606 on SVI (peering point).There is configuration made on the 3560E port, that prevents storm of ucast or bcast kind. This is: switchport block multicast switchport port-security maximum 1000 switchport port-security switchport port-security violation restrict storm-control broadcast level bps 1m storm-control multicast level bps 1m storm-control action shutdown storm-control action trap no cdp enable no lldp transmit no lldp receive spanning-tree portfast spanning-tree bpdufilter enable spanning-tree bpduguard enable. [code]
I want to get info not only about the fact of storm attack but also about at least source and destination of it (i.e. source and/or destination MAC). Perhaps this could be some logging messages.Are there any means for this on C3560E-UNIVERSAL-M (IOS ver 12.2(53)SE2) and 7606-S.

I have 2 ME3600Xs and utilize Broadcast and Multicast storm control on client facing interfaces. One of my ME3600s is reporting a Multicast storm and that a packet filter action has been applied. The strange thing is that it is showing up on an Admin Down interface that has nothing connected to it. [code]

We have around a dozen Catalyst 3560 and 2960 switches in a ring topology. We are considering adding storm control to our trunk ports. Up until now we have only used it on edge ports with default values and without error-disable.I am proposing that we also add storm control to trunk ports at a lower level and that we error-disable only the redundant links that make up our loops.
-storm-control broadcast level 25.00 20.00
-storm-control multicast level 2.00 1.00
-storm-control action shutdown [only on redundant links]
In a storm all links will restrict broadcast which should work accessing remote switches, but the redundant links should errdisable and block the redundant path. It is important that the action line is not applied to links that are not redundant as we could isolate parts of the network. Any reason not to use storm control on trunks?

There is NO connection although Belkin Wireless Adaptor is blinking to catch signal.Whenever there is no connection, I need to click Belkins Utility at System tray at the bottom in order to get connection, however it does not keep connected and lasts only 10-20 minutes.Besides this, I found when I clicked, icon of Belkin > Properties > Network and found there is no 'Use Windows to configure my wireless network settings.

Having just solved the missing network controller on my Dell Inspiron laptop I thought I would try the old Dell dimension 455-0 desktop I have. It too is missing the network controller, I can access web through wireless usb but not though cable or wireless. I have the disc but I can't install from it as I get message saying it is outdated. Tried Intel but the download ends prematurely and so doesnt work.
