Intel Dual NIC - Only 1 Works At A Time?
May 19, 2012
I have installed an Intel PRO/1000 MT Dual NIC into an HP Elite 8200 box on which I'm running Citrix Xenserver 6. The HP box also has an onboard NIC which works fine.
I'm having problems with the dual NIC. If I plug a cable into one or the other, but not both at the same time) that NIC lights up and shows as connected in the XenServer console. But as soon as I plug a cable into both NICs neither of them lights up and XenServer seems to lose sight of both of them.
Why can't both work simultaneously? Do I need to run an Intel utility of some sort on them to configure/flash them in a certain way for a Linux box (XenServer is based on Red Hat)?
I have also tried getting them both to work when booting into a Linux Live CD so I don't think it's a XenServer problem. I have also found that the exact same problem exists when the dual NIC card is installed in a Windows 7 system - one of the NICs will work, but as soon as you plug a cable into both the lights go out. So it doesn't seem to be an operating system issue.

I'm trying to save a neighbor some money by fixing their wireless network.WNDR3700 Dual band Netgear router.2.4ghz wireless b/g/n with enabled SSID broadcast, channel= auto, mode set to 130Mbps WPA-TKIP + WPA2-AES. wireless isolation is not enabled.5Ghz wireless a/n enabled SSID broadcast, channel = 44, Mode is up to 300Mbps..No security encription. (i know...bad, but the lady has lots of kids and family members coming and going from the house so she doesn't want one encripted). Video network enabled..Both Radio frequencies are enabled, fragment and CTS/RTS set to max WPS settings = keep existing. IPv6 not enabled, No repeating is enabled, No guest networks are enabled(however ssid broadcast is enabled for guest profile 1)The problem, and reason for fixing the problem is that the 2.4 Ghz band light on the router is ON however the SSID is not being seen by any client in the house. the netgear interface says it is on and working. the neighbor needs the 2.4ghz band to work because the printer is wireless and will only recognize 2.4Ghz SSIDs. Also they have older nintendo DS clients they would like to use on the network.During the day the 5 Ghz band works with very seldom (1-2) disconnects while the 2.4 Ghz band wont be visible to any device. in the evening both bands will come online, and very often will every computer get disconnected from either, the 5Ghz band will stay online longer than the 2.4 band and it seems as though every 10 minutes everyone gets disconnected from 1, and then all the sudden the other band will start working. once every so often both bands will be visable by all computers however only 1 will work.
-Updated the firmware, appeared to fix the problem. Fix only lasted for about 5 hours.
-turned off the router and modem to let them sit. restarted both multiple times.
-Called netgear tech support, asked me about firmware, restarting, then rerouted me someone with more broken English and a horrible phone connection than ive ever seen or heard. then they tried to charge me 30$ for a 1 time. or 100$ for the year. might as well buy a new router at this point in costs.
My personal fix would be to just broadcast on the 5ghz band and wire the printer to the router, buy another router and broadcast the 2.4 ghz one from it, but the lady wants it all to work with the one router. i dont know if the networked has ever worked as intended and ive spent hours reading forums.the main issue is leaving her with internet that she and her family can use so kids can do homework and stuff after i leave the house.

I have a problem with my Lenovo y560. One of the members here had the same prob. but his thread is closed,so i can't write him anymore. PM also doesn't work.[URL]"...I have a Lenovo Y560 that worked fine up excepting a keyboard issue that I fixed based on a youtube posting. The fix was to tape a small piece of antistatic tape under the keyboard over a screwlike piece of metal. Apparently that metal was causing static by rubbing against the keyboard data cable. It fixed the problem. Previous to the fix, various keyboard keys prompted shortcut keys (maddening and couldn't type).After assembling the keyboard and the top of the keyboard pad (was very careful to not bring static and assemble properly), the wireless connection began to drop. I have another laptop (Asus) with a similar set-up but a Centrino wifi card (vs. Intel 1000 bgn for the Lenovo) and it was connecting to the wifi no problem. Often, I'll see a yellow sun symbol over the wifi bars or a blue animated circle or a red x. Changing the standard settings does not work. Attaching an ethernet cable brings up a perfect connection.
1) I've covered an antenna of some sort with the anti-static plastic (pea-sized piece).
2) My wifi card is bad and coincidentally went out when I fixed the other problem above.
3) When the keyboard problem existed, I hit a shortcut that reconfigured the wifi somehow (but it worked fine before I opened up the keyboard.

reliability of the ET dual port server adapter. I have a Windows Server 2012 hyper-v host thats used to run all of the vm's I use in my house on an ASUS P9X79 WS motherboard. The board comes with 2 Intel gigabit nic's, one of which is an Intel server nic. Ever since installing Server 2012 it only registers one onboard adapter for use and the other isn't. Because of this I am planning on getting a second server grade network adapter for the vm's to use and have the onboard dedicated to management only. The only thing currently holding me back is if the OS will properly detect and run the network card in a non-server motherboard? Any insight as to if it will work on my board or not? Google has only revealed uses on server boards and not workstations.

my internet works normally during daytime but starts to disconnect and reconnect every few minutes at around 11pm. I've tried restarting my modem but to no avail. My home telephone line is not working when my internet starts disconnecting and it starts working during daytime. My modem is connected to the telephone.

I know now that this is a Desktop motherboard, officially not supported for Windows Server operating systems, but I would still like to get it to work. I've confirmed that the motherboard network works in WinXP (Intel 82579V Gigabit) and typically the 32-bit Windows XP drivers work on Server 2003 as well. Several of the other drivers have installed just fine, but the network driver install package fails with "No Intel Adapters are present."
I am trying to install Windows Home Server v1 (based on Windows Server 2003) on this box and just want to get a basic network driver up and running. I've checked the BIOS config, and Device Manager shows a yellow question mark by "Ethernet Controller". The ID is:
PCIVEN_8086&DEV_1503&SUBSYS_20408086&REV_043&11583659&0&C8 but I don't really know what to do with that...

I would like to make a design with 4 Nexus 5596UP. 2 of them equipped with Layer 3 Expansion Module so they can serve as core layer and the other 2 Nexus used as Layer 2 for aggregation server layer.The 2 Nexus in the core layer will run HSRP and will peer with ISP via BGP for Internet connection The 2 Nexus in the aggregation layer will be configured as layer 2 device and have FEX and switches connected to them.What I am ensure of is how the vpc and port-channel configuration should look like between the 4 nexus. What I was thinking is to run vpc between the 2 Nexus in the aggregation layer and between the 2 Nexus in the core layer. Than I was thinking of connecting each Nexus in the aggragtion layer to both Nexus in the core layer using port-channel and vice-versa.

how to change our wireless setup. Currently, we have 2 Cisco AiroNet 1130 WAP's in the office that go directly into the 2 POE ports on our Cisco ASA 5500. These WAP's have 1 SSID and are using WEP for security. After demonstrating the flaws of WEP to my boss, he has agreed that we should use something more secure and I've suggested WPA. We want visitors to our office to be able to hop on our wireless but on a separate guest SSID with WEP.
I'd like the internal SSID to route to the ASA and take the default route to the internet (it will be our new fiber connection once it's installed in a couple weeks). The default route is whichever connection is working since our ASA 5500 will fail over when it detects an outage.
I'd like the guest SSID to route to the ASA and then go over our existing cable connection. This connection will be our backup once the fiber connection is installed. Since we won't be using it very often, but will be paying for it, I advised that we send all guest wireless traffic over this connection since 50/5 is plenty for guests.
The current SSID (which will be the internal SSID) has no VLAN. We do currently have a few VLANS on our network, one for voice (.42) and one for data (.100) and the default (.0). What device to I create the VLAN on (Cisco 5500?) and how to I setup the WAP? I need very basic instructions to start and I'm also trying to do this without causing downtime if possible.
I've attached a diagram of what it should look like. Red indicates our internal network and Blue indicates the guest network. I can send screenshots as well.

I wanted to ask a question about the diagram I have included. We are bringing up 2 MPLS WAN connections and would like some specifics on the best design. We are using BGP to the providers. From there we have big questions. We can run BGP internal and are licensed to do so on the N5K's. The N5Ks are currently using HSRP for inside LAN clients as default gateway. We want to load balance and provide redundant routes using a dynamic approach. Should we use BGP internal utilizing the connections between the routers? Should we use HSRP on the routers? How best to get the routes to the N5K and should we be considering this?

I recently purchased a X2000 ADSL modem/router combination. For some reason the current time will not stay set to the time zone. Rebooting clears the discrepancy for a short time before it drops an hour exactly. I'm in the central time zone and the setting are correct on the basic setup.?

Is the WAG320N iPv6 compatable ? ,or could it be with a firmware update ?.Is the X2000 in the same boat in iPv6 terms as th WAG320N ?.Is there a way of retrieving "UPTIME" / "DSL connection time" information from the WAG320N and also line attenuation stats etc.Wouldn't need the above but poor isp needs keeping an eye on.

I run 2 RV042 V1 for home and office with Gateway to Gateway VPN connection with single WAN connection in use. Everything works like a charm!
I was even able to create VPN connection with 2 WAN connection on one Router and 1 WAN connection on another with Smart link failover and VPN Tunel Backup.
I got problem though when i tried more complex connection diagram. [URL]
So basically I now have 2 ISP connections on each point with Static IPs and I'd like VPN Connection to be alive for ALL 4 options automatically with failovers (smart links) And tunel backups but i'm not sure if that's ever possible with my equipment.

AI have a Dir-825 router. The 5GHz is turned off and the wirless is on G/N. I have shawcable for my isp and my firmware is 2.06 and its a Rev B Router. I also have Qos Engine on for allowing me to have 2 xboxes on Open NAT.problem is my wireless signal for some wired reason is VERY weak. A while ago it used to work really far way outside. It was around 150ft distance at 4 bars. Now for some reason I can't even go upstairs without getting a 1 or 2 bar signal.

I recently upgraded to a Intel EXPI9301CTBLK (PCIe) and have been having trouble with the connection disconnecting. Mostly I have noticed it when I have a torrent running with a lot of connections, but it has happened at other times as well. If I have 3+ torrents running it will disconnect every fifteen minutes or so. If I unplug the cable and reconnect it everything works fine. Otherwise it seems to work perfectly fine and will transfer files from my file server at 95+ MB/s.
I running Windows 7 and have not installed any drivers other than the ones that the OS automatically installs.

This first started happening a couple of weeks ago when a piece of software was put on to the computer off an external hard drive. First the wifi would turn itself off but after turning it back on it might happily stay on for a few hours before switching itself back off.The day before yesterday it decided to start turning itself off straight away. I plugged in with ethernet, uninstalled the old drivers and reinstalled new ones, this didn't seem to do anything so I turned on my firewall and titanium defense and after a while it decided to start working again.Earlier today I connected my DSLR camera to my USB 3 port to download pictures, this killed my wifi straight way. I reconnected with ethernet and I'm not sure what I did but now the wifi has decided to work again.

I'm running Win7 on a Lenovo x200. Has run fine for a year. Lately the wireless card disconnects and the system shows no available card. Have to reboot to reconnectThe card is an Intel 5100 AGN. Have tried uninstalling all software and reinstalling latest drivers from Intel and Lenovo. Have tweaked power saving controls, and tried about every suggestion out there. But the problem persists.

I've been having some issues lately where if I am copying large amounts of files two and from my NAS and thus saturating my gigabit ethernet, web browsing and internet streaming slows down which is a bit of a bummer. I figured I might fix this with link aggregation.
My switches (Procurve 1810G-24 in basement and 1810G-8 in office) both support 802.3ad Link Aggregation. It works beautifully to connect them together, as well as to connect my FreeNAS box to the switch as well.
how do I set it up to work with my Windows 7 box?
I can't find the options for 802.3ad in the windows menus anywhere, and googling has not led me to the answer yet...
My motherboard has two on board Intel gigabit ports (Intel 82574L and Intel 82579V). Is it possible to link these two, or do I need to pick up another Intel PRO PT dual port copper gigabit NIC like I have two of in my server?

I let him take control of the system, he ran [URL] with me 6 feet from router, and then again 30 feet. Huge difference in speed, approximately 10x slower at 30 feet. He initially stated the problem was with the antenna connection and offered to send a tech to replace the antenna, which requires a display replacement as well. I was skeptical so pressed him to verify that this was a known solution since there were so many complaints. He was absolutely certain this was the issue, but put me on hold to double check. He came back and stated they needed to replace the wi-fi card from the Dell 1901 to Intel 2230 along with the antenna. As a former antenna engineer, I suspect the problem is the design of the antenna and/or its location, and not the drivers or wi-fi card.

I've been trying to setup a wireless ad hoc network so I can connect to the internet using my iPod Touch. My wireless adapter is Intel(R) PRO/Wireless 3945ABG Network Connection running the most up-to-date driver.
- Set it so Windows configures my wireless network settings
- Created a wireless ad hoc in Wireless Network Connection Properties
- Changed it so that network access is given to ad hoc networks only
- For my LAN connection under Internet Connection Sharing, "Allow other network users to connect through this computer's internet connection" is ticked I am able to connect to the network that I setup but when I try to connect to the internet it fails.When I check the Wi-Fi Networks setting on my iPod Touch it gives this information:
IP Address: 169.254.1.158.228
Subnet Mask: 255.255.0.0
Router: (blank)
DNS: (blank)
Search Domains: (blank)
Client ID: (blank)
I checked and that IP isn't my IP?

my Intel wireless card keeps losing the connection. Until a couple of weeks ago it would be fine for roughly the first 20 minutes then the connection would just completely drop out and the only way to get it back again is to go into the network and sharing centre, disable the network card and then reenable it. Most of the time this works, but again for only the first 20-30 minutes, then I have to do it again. Occasionally it works for for longer but that's a rare occasion.Now not only does it do this, but also, if I put my laptop into sleep, sometimes when I turn it back on again the card will not connect to the network and I have to do the same disable and enable process.[ODE]

I installed an Intel 4965AGN into my Dell Inspiron (running Windows 7) to connect with 802.11n to my D-Link DIR-655. It refuses to connect in N mode, it will only connect in G mode. I have tried everything I could find online. I set security to WPA2-AES, and even tried with no security with no luck whatsoever. Before the 4965AGN i had an Intel 5300 which had the same problem, but I returned it because I thought it was a problem with compatibility with my Dell. Apparently something else is the culprit. What could I be over-looking?
