Realtek Gigabit Lan Slow To Connect To Router?
Jul 18, 2011
I have a Gigabyte motherboard that ive just installed into my dads new PC and the gigabit LAN has started taking 60 seconds to connect to router, very annoying...sitting with browser open waiting for it too connect... the issue seem to first appear during windows updates, i uninstalled device driver, rebooted and reinstalled the driver off disk... this sorted the issue.. THEN windows installed more updates, however these were nothing to do with networking (Office updates) and its back ...ive tried downloading the driver from gigabyte (newer) but still the problem persists...
Core-i5 2500k
4Gb 1600Mhz RAM
GTX 460 OC
60Gb SSD Vertex 2E
500Gb Seagate SATA-II
Gigabyte P67A-D3-B3
Windows 7 x64

I recently said to hell with wireless and wired my apartment with Cat6. My desktop computer next to the router is running fine at 1Gbps. My media center one room over is only running at 100Mbps, and I cannot figure out why.
The motherboard has a Realtek RTL8168D . I have green ethernet enabled... could that be it? Auto disable gigabit is disabled. I tried changing speed & duplex from Auto to 1Gbps, and that didn't change anything. The latest driver is installed. Their ethernet diagnostic utility shows the link speed at 100.

I am having a problem with my Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC. It is not detecting my ethernet cable, and thus leaving me without internet on my desktop, after i updated its driver. The cable is not the problem as I have tested the cable with my laptop. I tried rolling back drivers, doing system restore and removing drivers with driversweeper and letting windows install the drivers again. However, none of these worked for me. I doubt the NIC is faulty as it was working before i updated the drivers. I am using windows 7 home premium 64-bit.

I recently bought the E4200 thinking it would be the latest and greatest, and I wouldnt' have to worry, but after just a simple test of transferring files between my Home Server, and my PC (Both connected over Gigabit ethernet using CAT6 cables, with only the E4200 inbetween).I use to get anywhere from 40 MegaBytes/second to 50MegaBytes/second on my D-Link 655.But now I am lucky to barely get 20 MegaBytes/second. Is there an issue with this router? or am I expecting too much from Linksys?

When I install a micro-wifi-usb 802.11n with "Realtek RTL8188CU" on a old notebook with Windows XP I get maximum 1.5 to 2Mbits/s. Though installed on a newer notebook with Windows 7 I get 30Mbits/s.Other wifi-usb, Cisco Linksys WUSB100v2 does work on that Windows XP machine at 30Mbit/s, but the dongle is much larger The router Cisco WRT320N is just 5meters away and I always have excellent signal strength.I tried some other drivers without any luck. On the site of Realtek I don't find any driver except with some letter diverence at the end of RTL8188CU, which I also tried.

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.

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.

Last month I decided to upgrade my network and switch everything from 10/100 to 10/100/1000 (gigabit).My setup I'm struggling with right now :
Desktop Running Win 7 x64 with a 1 gigabit NIC (running latest drivers from Intel)
Linksys E3200 Router w/ Cisco 10/100/1000 x 4 ports (Latest firmware)
USB 2.0 NAS with a WD 160SB HD 7200rpm (100MB/s)
On file transfers from the NAS connected to the Router, connected to the desktop with a CAT 5e 5ft cable, I'm pulling 9.5 MB/s MAX
Everyone I talk to say, "wow, that's what 10/100 runs" and that I'm not running one gigabit. They say I should be seeing at least 20MB/s. What am I doing wrong here? I've trying play with buffer size, settings on the NIC, MTU on the router. I'm lost at what to do.

I have a PC with an onboard Realtek 8168 PCIe Gigabit connected to a D-Link 655 Gigabit router.Here's the odd situation: when speed/duplex is set to 100Mbps, my upload speed using www.Speedtest.net is fine (~3.0 Mbps). However, when I switched it over to 1.0Gbps, it goes down all the way to 0.06 Mbps. Download speed is generally unaffected. can't tell which is the likely culprit!
Onboard NIC faulty/underpowered?
Faulty cable (highly doubt, I've tried 5+)?
Or is it a matter of settings? I turned off QoS and WISH on the router, but it didn't do much.

I have setup an Asus RT n16 with 3 computers that support gigabit ethernet and a media server on one floor. On the other floor I have set up a fast ethernet switch (connected to my asus router) which is connected to several fast ethernet enabled computers.
Would the fast ethernet devices slow down the entire gigabit networking to 100mbps connections on my floor - similar to how a wireless n network running at 300mpbs must slow down to 54mbps when a wireless g device is connected to it?

I realize this is just a small business switch, basically a rebranded Linksys, but why I'm only getting 200Mbits/s
- 48 port - 10/100/1000 , set to standalone mode
- 3 separate PCs on this switch , all are fast machines with Core 2 duo / plenty of RAM etc...
- all 3 auto-sense 1Gbps connection
I use iperf tool for bandwidth testing and no matter which PC I pick as server, which as client I get about 150 to 250Mbits/s
I am not looking for full 1000 here, but 200 seems rather sad....
- jumbo frames seem to make no difference
- I am using TCP test in iperf , standard no extra flags , 10 seconds, 20 seconds or even 30 seconds all come out the same.
- wiring is shady as some of it is just Cat5 , but when going from one laptop on the switch to another with brand new Cat6 cables I STILL only got 200.

So I finally got all my parts delivered to setup a home file/backup server this week.
It's currently running Ubuntu Server and I'm using Samba to share files on my network.
The server currently has a 2TB WD Green drive in it connected to a Asus M5A78L-M
This is then connected via CAT6a to my new Gigabit switch (TP-Link TL-SG1005D).
My home desktop is then also connected to this switch and again also through CAT6a cable.
Currently when transfering files I will get a perfect 100MB/s read from the server to my Windows machine. When copying from my Windows machine to the server I get around 30/38MB/s.
I know this drive is capable is faster speeds.
I have found ftp's write speed is much closer to what my Samba read speed is so I'm going to give it a guess that is a software problem rather than hardware

I have just purchased a new laptop (HP Pavilion G series) for my studies at university. The wirless works fine when I am connect to my network at home, but I am only able to connect to the university's network when an ethernet cable is plugged in. Everybody else I know, who has a similar setup to myself has no problems connecting to the network without the ethernet cable and I was curious as to why this might be.
I am running on Windows 7 and the wifi adapter is a Realtek RTL8188CE 802.11b/g/n
As I say I am quite a rookie when it comes to computers

I can't connect to the internet. I'm currently using a USB internet, but the problem still exists. So it's not working with either cable or USB internet. It just won't connect. I've thought for a long time that there is probably something wrong with my network card, but I've run some tests that I saw on the internet, and it appears as if the network card is fine. I've also thought that there might have been a program or something that I installed that could have caused this problem, but I can't find the problem. When I go to the device manager, I can find one network card called: "Realtek PCIe GBE Family Controller". I've tried to reinstall the card, but it doesn't work. I can't find any software on the internet for this card either.

About two weeks ago, I took out the old motherboard of my HP computer and put in a new ASUS M4A88T-M. The board is amazing, especially for the money, except that I can't connect to the internet.So, for the last two weeks I've power-cycled about a billion times, ipconfig /this/that/and the next thing over and over, I've winsocked, I've turned programs on and off and on again, checked that the LAN is enabled in BIOS, firewall is off, and probably a bunch other things from the 100's of google pages I've searched.I spent 45 minutes on the phone with my ISP, and the guy was 99% sure there is something wrong with the NIC. Windows says that the device is working correctly, and I think that it is. There must be some setting, some driver, something that will reconnect me to the internet.

I have a wireless modem/router that I connect to my PC thru USB cable and working fine. I newly installed Lan Card (Realtek RTL8139/810x Family Fast Ethernet NIC) and it doesn't connect to internet. It says connected with 100Mbps but Received data bytes are ZERO.
I did ipconfig/all and got all static address I had given while setup. When I "ping 127.0.0.1" it works fine. When I ping 'default gateway IP' it also sends/receives data. When I try to install the driver I got in the CD along with the LAN card, it says "you have already installed recent driver needed etc. " and doesnt allow me to install from the CD. Currently it shows 'Driver Used as : c:windowssystem32driversRtnicxp.sys'

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)

trying to connect an old PC to my home wireless network.I brought home a PC I have used for years at my office. I have it configured with a Realtek wireless card and was able to connect it to my office wireless network without a problem.But, when I try to set it up at home, it won't take. I have a dlink router that is working fine with several Mac computers in my home, so I know the router and network are up and running fine.The PC uses Windows XP. The icon in the lower right corner says dlink is connected and there is strong signal strength. However, when I check the dlink status, it shows that 2,573 "packets" are sent, while "0" are received.I've tried to connect to the internet using Mozilla, Safari, and Explorer. Each says the server cannot be found and that the internet is not connected.

My laptop will not connect at full speed whilst on a wired connection. All my other laptops connect at full gigabit speed OK using the same cable. My XPS will only connect at 100Mbps.I have the Realtek PCIe GBE Family Controller.
I am using Win 7 64Bit but I have also tried Ubuntu 12 with the same result. Is this a known problem ?I think this may have been like this since new, My most expensive laptop is the slowest on my network.

I have set up a wireless home network using ADSL with the following components: TrendNet TEW- 432 BRP Wireless Router Gateway Desktop with Windows 7 OS, iMac desktop with Leopard 10.5.7 OS Compaq Presario Notebook with Vista Home Premium OS Service Pack 2 I am able to connect to the network with all 3 but I have a problem with the Notebook. It is very slow to connect and sometimes takes 15 minutes or more to find the network. Once it is connected it works fine and doesnt disconnect, but if I have to reboot for any reason the same problem occurs. It does not appear to be a problem with the placement of the router and the signal strength which is "very good" to "excellent". I say "slow to connect (again)" because this had occurred before and I returned the laptop under warranty. HP replaced the wireless network card and it worked fine, but the problem has come back over a year later. I suspect that the card is not at fault and that the problem is elsewhere but I am at a loss as to what it might be.

I just installed 2 new units and neither will connect to a new HP gigabit switch - no link light, other devices can connect to the switch OK. Their gigabit ethernet settings are set to auto for duplex and speed. I also tried forcing one of them to full duplex and 1000 Mbps which didn't work either. They're both powered by POE injectors. If I connect them to a 10/100 switch they work fine.

I have that red gigabit router with the 150/65 service. It connects via ethernet for internet and has a coax to transmit the guide data etc.So my idea was to just leave the Verizon router connected and on (with wi-fi off) so it could do the TV stuff and just plug my router into the ethernet wall port the Verizon guy installed.Not so easy of course, my E4200 will not recognize the ethernet from my ONT (I think that's what the device they put in my basement is called) and the internet doesn't work. I have factory reset the router.The reason I am doing all this is because the wireless range of the e4200 at 2.4ghz is near unmatched and given my house, the actiontech cannot reach my room.

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.
