I recently built a PC with an ASUS P8P67 mobo that uses the Realtek 8111E Gigabit LAN Controller. My issue is that it won't even open a connection to the internet when I plug the ethernet cable from the motorola SB6120 into the port on the mobo.What's odd is if I keep the cable modem plugged into my D-Link Di-624 wireless router and then just use the LAN ports on the back to route an ethernet cable to my mobo, all works just fine. But I am sure this is at the expense of a slower connection speed through that old router right?The modem turns the LINK light BLUE, seeming to indicate a gigabit connection if the above router-skipping connection is used, but still there's no connection to the internet.
A few days ago, I noticed that my computer wasn't picking up my wired connection anymore while the wireless connection was still working fine. I opened up my network adapters and my Local Area Connection adapter wasn't even showing anymore, only the Wireless adapter. I updated my drivers, tried different cables and even a different router but still no dice. This morning, when I booted up my system, Windows said it was installing driver software for Broadcom Gigabit Ethernet Controller. I got really excited when I saw Local Area Connection in my adapter menu and plugged in my ethernet cable. Nothing happened and my laptop refuses to recognize the ethernet cable plugged in to it. It's a Dell XPS 1640, Windows 7 x64 with Service Pack 1.
P.S. Usually a little orange light appears in the ethernet port on my computer when a chord is plugged in. When I turned on my computer this morning with the chord in, the light was on. When Windows finished booting, the light went off.
I recently got a Dell Latitude D600. I know, it's outdated. I'm running Windows XP SP3.
My problem is that after installing all of the drivers for the Broadcom 570x Gigabit Intergrated Controller, I can't get the wireless to pop up in the bottom right hand corner. I can only connect with an Ethernet cable directly from my router. I have tried many things, even support packages, but I can't seem to get it to work. I've also tried Fn+F2. Also, in the Device Manager I see a "Network Controller" but it has a question mark that is yellow beside it, and I can't seem to install it.
I have an Ethernet Loopback Plug (4 Pairs) made and trying to test the Gigabit Interface on a 3845 Router with a fail result. The interface will show up/up only if I set the interface to 100M/Full Duplex when I plug-in the Ethernet Loopback Plug (4 Pairs). I don't see this Gigabit Interface @ 3845 router has any option to set it to internal or external loopback.
I'm running an Optiplex 330 with the Broadcom NetXtreme 57xx Gigabit ethernet card.
The computer is running Windows 7, 64bit, but there do not appear to be any drivers for that OS.I tried selecting Vista 64bit, but there were no drivers. The Vista 32bit doesn't work.
Then I went to Broadcom and found these drivers: [URL] the W764bit drivers didn't change the fact i'm still on a 100Mbit card (as seen on Local Area Connection Status screen and the Device manager)
2 days ago I bought Verbatim 2TB NAS with Gbs ethernet and connected it to Cisco Catalyst 2970 Gigabit switch. When I log in to cisco CP, monitoring tools shows that connection with NAS is 1000 Mbps, but file transfer speed is only 9-11 MBs per second (screen 1 and 2). This means that connection is 100Mbs, right?
So, how can I fix this, what is the problem with this NAS. I formated it from ext2 to ext3, nothing has changed, then restored it.
I am trying to set up a connection between 2 pc's. It's a direct cable connection. The problem that I am having is that the connection isn't gigabit. I know both network cards support gigabit. I checked in the device settings and in one pc I can see in the Speed & Duplex the 1Gbps option but on the other pc I can't see that option despite the fact that the network card is gigabit.
I have quite some files to copy from one pc onto another and I really need a good connection between them. I can't really remove the hard drive because it would void the warranty.
Could this be a driver issue or a cable issue? On both pc's I have windows 8.
The network card on the pc that doesn't have the 1 gbps option is an Atheros ar8161 card.
I have a PC with a Realtek onboard Ethernet controller, running Windows XP. It's connected to an Asus RT-n16 router loaded with TomatoUSB, via a Cat5e cable. When I set it up a month or two ago, I confirmed that I was getting a Gigabit connection to it--the little network connection icon in the Windows XP taskbar indicated "1.0 Gbps." All well and good. I just happened to check it today, and it now says "100Mbps." Nothing, as far as I know, has changed to the configuration. I went into the Device Manager, and saw that under the driver settings, in "Speed", it was set to "Auto-Negotiate." When I tried setting that to "1.0 Gbps" instead, the network connection icon in XP's taskbar once again indicated "1.0Gbps." As an experiment, I then changed it back to Auto-Negotiate, and once again the taskbar icon read "100Mbps."So I guess I have two questions. 1) Should I leave the driver setting on 1Gbps rather than Auto-Negotiate? (2) Why might the speed have switched from 1Gbps to 100Mbps over the past month if nothing's changed?
Purchased and configured 2951 router based on Telco specs that required T3/DS3 card with coax connection for MPLS. When telco showed up to install DS3 they handed me a UTP copper connection.... Can I use one of the Gigabit ethernet connections on the 2951 as my MPLS interface into the provider's cloud?
My new computer has a problem with the on-board gigabit ethernet it keeps dropping network connection every few minutes. Nothing has had any effect. It has been such an annoying problem, I really was hoping to find a fix for this sooner as I know other people have had similar issues. Does anyone have any other ideas because I would like to use the only ethernet connection sometime in the near future. Having to run of an WPN11 netgear usb adapter at the moment.
my router is sitecom gigabit 300N. since the past week there is this yellow exclamation mark on the connection in the task bar, near the clock. if I pass the mouse over it, it says no internet connection, eventhough I'm connected to the internet and I'm writing this right now, this is on desktop pc and connected to router by cable. the same thing on my laptop that is connected through WiFi, the signal strenght is normal, but there is the same exclamation mark. I'm pretty sure its the router not the PC because this happens on two different machines with the same router. I tried turning the router off and left it that way for about 7 minutes but that didnt work. is there something in settings I should do? or throw it away and buy Linksys/D-link router?
I am using a E2000 connected to a DSL modem via the internet port. My modem is able to connect at gigabit speed but it doesn't seem to be the case with the E2000. All other ports are running at gigabit speed without problem. Is there any parameter that can be modified or is it a router limit?
I have the possibility of upgrading a DS3 to Metro Ethernet, Gigabit connection. My dilemma is I have two VTP domains in my network. How can I get two VTP domains over one trunk to a remote site ?
I have a Netgear N600 WNDR3700v1 Dual Band Gigabit router and am having a problem with the wired connection with my PC. Everything wireless in the house works fine. In fact, I also have a Direct TV box hooked up for on demand and a sling box hooked up (both wired) and they work find. It's just my PC that is having issues. If I bypass the router and hook straight into the modem, it runs fine also so I have something going on between the router and this PC. I updated the NIC driver and this did not work. Before the update in the device manager, it said it was a NIVIDA nForce Network Controller (if I remember right) and now it says NIVIDA nForce 10/100 Mpbs Ethernet. It was suggested that I change my speed and duplex to match the router after I update but I am unsure what to change it to.
Have just acquired new used HP desktop running Windows Vista. System has a Broadcom NeXtreme Gigabit Ethernet card installed, which gets me to the internet OK when using a LAN cable from wireless router. But I can't make wireless connection. Vista tells me that I need a wireless network adapter.Am I missing something? Is it possible to change some settings to get the Broadcom card to go wireless? If not, what sort of adapter is needed, and is such adapter external or will it have to be installed in the system box?
Network Adapter (as displayed in device manager) Realtek PCIe GBE Family Controller (says this device is working properly)
Motherboard chipset Intel p67 Processor i5 2500k Windows 7 x64
I'm running my lan on the integrated network adapter "Realtek PCIe GBE Family Controller" on my motherboard. When I plug in the lan line directly from my router the speed on speedtest.net is around 2 Mbps, i have tested on 2 other computers and they all get around 10 Mbps with the same line. I build this new machine to play games, and sank $800+ on it. I am trying very hard to figure out why my LAN speed is so slow.
I am worried it is a mother board defect, but it is unlikely as I can still browse the internet and stream video. I just get slower download speeds and more lag in games which defeats the purpose of building a gaming computer . I have disabled my avast and my windows firewall to test the speed.
I have also tried buying a wireless card (Netgear N300 Wireless PCI Adapter) and it peaks at around the same 2Mbps. My other computers get 6+ Mbps wireless on speedtest.net at the same location from the router.
Because both LAN and wireless seems to be caping out at 2Mbps could this be an indicator of some sort of internal limiter on internet speed? Or even worse, hardware defect? I'm going to get a USB wireless adapter tomorrow and test the speed.
What I have. 2 - WLC2125 controllers. Second unit is failover purpose only.
19 - Cisco Access points. AIR-LAP1242AG-A-K9 - All powered by Cisco Power Injector AIR-PWRINJ3.
Issue: 5 AP's in another building loses connection to the network and drops off from the Controller. Sometimes it's all of them. Sometimes it's just 1 or 2 or 3 of them. Happens very randomly. Somtimes once a week. Sometimes, once every two weeks. Only way that I know how to get them back up is to just power cycle them. Once power cycled it comes right back up.
This has been happening for awhile now and I really need to get to the bottom of this. I understand it can be number of issues, like cabling, or power issues but what I really need is a steps to troubleshoot to narrow down. what to look for, settings on controller? etc...
I received a 5508 WLC, that I wanted to configure as a guest anchor for our DMZ. I stepped through the console configuration. Now that the setup is complete, can I attach my laptop directly to the copper SFP, and access the WLC web portal? I gave my laptop an IP address, in the same subnet, but still can't connect to the portal, or ping the WLC IP address.
I came across this issue with a number of APs in an installtion last week.All APs were new LAP1142s and the controller is 5508.None of the APs (14 in all ) were able to join the controller.Actually they started the joining process , but it seems to get disconnected in between.I am pasting the output below.
Interestingly the issue was resloved after i Resetted All the LAPs again. (all 14 of them worked fine after the reset , but there were no prior configurations on the LAPs , they were just opened From The Box).
*Apr 13 07:47:37.899: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY *Apr 13 07:47:37.900: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY *Apr 13 07:47:37.971: status of voice_diag_test from WLC is false *Apr 13 07:47:48.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 10.2.4.52 peer_port: 5246 *Apr 13 07:47:48.000: %CAPWAP-5-CHANGED: CAPWAP changed state to *Apr 13 07:47:48.002: %LINK-3-UPDOWN: Interface Dot11Radio0, changed state to down *Apr 13 07:47:48.012: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to reset
[code]....
What is this .."*Apr 13 07:48:10.043: %MESH-6-CAPWAP_RESTART: Mesh Capwap re-started" that i see on the LAP logs.IWhy is this issue getting resolved on a reset , considering that all 14 of them are brand new , and unboxed at that very moment.

I know that the 3600 series APs are not supported on the 4404 WLC. However, would the following scenario be supported? I would like to use the 4404 (software rel. 7.0) as a guest anchor with a 5508 (software release 7.2) as the foreign controller supporting series 3600 APs. I ask because the APs do not need to join the guest anchor.
We have a customer that have 2 5508 as primary and backup controller and a 4400 as an anchor controller. We plan to upgrade the 5508 to 7.3.112.0 and the 4400 is already 7.0.116.0. Will there be any issue if the anchor controller is not the same code as the foreign controller? Do I also have to upgrade the acnhor controller to 7.0.240.0?
We are trying to navigate the waters in choosing between a in-house, controller-based, wireless network solution or a cloud-based solution. We have been presented with the usual suspects in cloud-based (Aerohive, Meracki, etc) and with Cisco (5500) and Aruba on the other side. We are a multi-campus organization with approx. 200 APs.Any hard reasons why go with a controller-based vs. cloud-based solution? If we must keep the conversation limited to Cisco, why go Meracki over Cisco's WLC solutions or vise versa?
I am looking to configure a wired and wireless guest network. I have industrial barcode scanners that connect to one SSID and then there is the business network on the office SSID (no vlan seperation for these devices just different SSIDs). There is not really a need to seperate the business network from the scanners in any case. However, there are needs for a guest network and this needs to be seperated. At the bare minumum I would like to have the wireless guest network. Here is what I have: 2125 Wireless LAN controller managing 18 LAPs (1 indoor and 17 outdoors)Cisco Cat 2950 switches (2 x 24 port and soon to be replaced with 2 x 48 port 2960's with 802.1x capability) Sonicwall TZ210 firewallOne existing wired and trunked vlan for PLC infrastructure. One ESXi hosting Windows server guests (soon to be 2 with vMotion) The reason for the wired guest access network is tp prevent anyone from plugging into the wall jack in the office with thier home laptops or anyone else from being on the same subnet as our domain machines. Granted they would be unathenticaed but there would be no layer 2 seperation and that is what I think would be best.
How would I go about doing this on the wireless controller without an anchor controller just using my existing hardware? I would like to have the Guest SSID only availible in the front office. Is it possible to offer a guest network while still servicing the business network SSID on the same access point? Then might I be able to have the guest network be treated as it should at the controller? However this might present another issue altogether as the guest traffic will be over the same wire as the business SSID until it hits the controller for management.
Should a computer running XP be able to use ICS to share its internet connection across a gigabit network to a computer with a Fast Ethernet card running Vista? If so, I have a problem and will post a more detailed question.
I assume I have done everything correctly but am not getting any speed increase when transferring files (in fact it has dropped a little) I currently get about 7.5mbps between my computer and my server. All are wired connections.I have the modem/router connected to the Gigabit switch and the switch is connected to my server and a PC. Slight complication is I use 200mb homeplugs to connect from the switch to the PC, the server is connected straight to the switch, also I am waiting on some cat6 cables I've orrdered I have no idea what I'm using...
DIR-655 Firmware: 2.00NA (most recent) Hardware Version: B1 I am not getting Gigabit LAN wired. I am only averaging 25% of that, which means 256mbps or 32MBps. note the following:
- Router only connected to two computers (wired), wireless turned off
- Cable length does not exceed maximum specified length of 100 meters (328 feet). Neither does it exceed the usual maximum length of 100 feet. (both ends)
- Cable is CAT 5e (both ends) allowing Gigabit speeds
- NICs on both computer are able to run at Gigabit
- Both computers recognize the Gigabit connection speed
- Sustained Hard drive speeds are rated at 101.9MBps and 86.6MBps or 815.2mbps and 692.8mbps (therefore, connections should run at least 692.8mbps or 69% usage)
- Minimal programs were running in the background (in fact, almost nothing except for the OS itself)
- Windows 7 on both computers
- Later, I ran a streaming of a file and transferring files over the network, the speed still remained around 25% usage, which means there's isn't a cap of network usage per program. (is there usually a cap?)
Things I don't want to hear:
- Cat 5e doesn't support gigabit
- Check cable has 8 cables instead of 4 (it has
- CPU not good enough (it's plenty fast for copying files, quad and hex core)
- Not enough RAM (plenty of that too, I don't know how much role RAM plays in transferring files over the network)
What the purpose for having a dual gigabit LAN would be? That is, having two LAN ports on your motherboard as I saw in a new MSI P67 model. I can see it for sharing your LAN through your computer if you don't have access to the router.
I have my asus rt n 16 running dd wrt and from there i have a gigabit run to a switch on the other end of my house i have about 5 devices plugged in and i am noticing some bottle necking with just that one run. i notice on the settings on my router i can aggregate ports 3 and 4. will this work with my switch to provide 2gbps i have a trendnet 5 port gigabit switch.
I have a Zyxell Modem/Router with 4 ethernet ports running 10/100, if i plug a gigabit switch in to this and then plug 3 PC's into the gigabit switch, (each PC has a gigabit NIC) will the router pull the network down to transfer all data at 100mbps or will the PC's continue to transfer at 1000mbps and only the connection from internet router will be at 100mbps.
