Home Network :: Gigabit Slow - They Say I Should Be Seeing At Least 20MB/s?
Oct 9, 2011
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.

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

Cable modem into cisco-linksys E4200. 2 of the ports going out from the router plug into the wall, where one goes to the master bedroom and one goes to the living room. Once it gets to the wall jack in each of those rooms it goes out to a gigabit switch. Each of those two rooms has a computer and a TV connected, and the living room as a blu-ray also connected to the switch.The third port going out from the E4200 router goes to another gigabit switch, which is connected to a couple more computers in that room.All of the cables are either cat5e or cat6. The long cables running through the wall from the server room to the living room and master bedroom is 24gauge 4pair cat5e, it was run by a general contractor.
When I transfer between any of the computers on the network as it sits I get 11MB/sec. I get that number by clicking more details on the file transfer. In the network tab of task manager it sits pretty consistently at 10%.If I move any of the computers to be connected to the SAME switch (i tested all 3) i can transfer around 60MB/sec.Based on this testing my initial instinct is to say that the cable running between the rooms is limiting the transfer speed. However the cable is cat5e and rated for gigabit. Neither of the runs are anywhere near 300ft long. Plus the consistency of the transfer speeds at 11MB/sec makes me think it's being clearly capped at 100base-T speeds as opposed to just slowing down due to interference of the cable.As a side note there is a place in the router that tells you the speed of each port. For some reason it has one of my ports listed as gigabit and the others listed as 10/100Mbps. The yellow 3 foot cable i have is listing as gigabit, when i swap it with another cable in the router it changes the gigabit port to the one this yellow cable is on, very odd, however regardless of whether the router says its gigabit it only transfers at 11MB/sec anyway.What I'm wondering is what could be causing this limitation besides the two cables running through the wall? Is that the only thing that could be doing it? What is the best way to really test it out? Do I need to buy some kind of network testing device that tests throughput?

I am currently looking to upgrade and extend my home network with preference to dual band and gigabit functionality. My problem is choosing the correct hardware.I want dual band to separate the network for the kids (a PC, laptop, Xbox 360 and phones all wireless) and set up parental controls and maintain connection speeds etc. For my needs I need the network to be connected to my Onkyo AV Amp (for internet radio and music streaming only), Blu-ray Player, Sky HD satellite box (all wired) and a PS3 (pref wired) and a few wireless devices all N capable. Apart from the obvious gaming capability I would like to be able to stream HD video to the PS3, PC (wired) and laptops via a USB HDD connected for now on an access point or modem router to save on the cost of having separate networked devices.
I currently have ADSL so I was looking to get a dual band gigabit modem router to serve the kids wireless hardware whilst my current hardware is on another floor and is connected with a wire from the existing modem but I have to keep swapping it from PS3 to amp etc.In short I am hoping to have a gigabit, dual band ADSL modem router and connect to a gigabit access point (with dual band if possible) via the cable I have sent to the other floor to wire up the 4 devices. I've currently been looking at Netgear and Buffalo solutions as I've had problems with Linksys and Belkin routers in the past. Would this be possible with just 2 devices (modem router and access point) whilst maintaining decent speeds and if so can someone shed some light as to what I should get.

Setting up a netgear n600 (WNDR3700) in my home. I have tried connecting two PCs to the LAN and am only getting 100mb/s with most of my patch cables(all are cat5e). I was only able to achieve 1Gb/s with 1 of my cables(which is actually a few feet to short for my shortest run). Both PCs have gigabit capability. What are the chances that 5 out of 6 cat5e cables are bad? Am I missing something?

I have a homeplug network as follows:
6x 85Mbps homeplugs in different rooms, each connected to a 5 port switch
2x rooms contain a PC
5x rooms contain a Squeezebox of various types
Router connected to homeplug
I have realised that I am only getting very slow network speeds of between 10-15Mbps (LAN SPeed Test)which affects Squeezebox's ability to play several devices synched up at a time playing 320Kbps MP3s
I have done some proprietory testing in my home by switching devices on & off & testing network speed accordingly but no significant gains seem to be made. One PC seems to report far lower speeds though at 5Mbps which is 3 times lower than the other PC. They are set up to read/write files from eachothers shared folders (but not simultaneously).1st question is, am I being realistic about the speed of data throughput I expect on a network of this type? I was expecting a much higher speed like 50Mbps.I wouldn't mind investing in the faster Homeplug system but having to buy 6x adapters isn't worth it if I will only get a marginal improvement.

I've got a 200mbps down/100mbps up fiber connection at home. When I do a speedtest I get around 192mbps down which is more then enough. However my problem lies around my upload speed, but only on ONE computer.

I've just setup a box with Windows Home Server 2011 RC. It's a AMD X2 with 3GB RAM. Everything is fine with that, but I'm noticing my internal network speeds are pretty slow. I'm seeing on average 0.8MB/s transfer speed between my PC's and the server, and between the PC's themselves. I have everything wired through a Linksys WRT54GS router.Is this as much as I can expect from this setup? It's painful trying to copy media files (music, pictures and HD video) to the server at such slow speeds! What would I need to do to get better speeds? I'm assuming a different router could do better.

Newbie network admin here and I'm having problem dealing with my LAN. I have two networks 192.x.x.x and 10.x.x.x, Configured at my Astaro 220 UTM, which obviously where the gateway is, from my UTM I have 3 isp connected which is the source for my internet. Now from astaro to my core there are two connection, 1 for the 192 network and the other is for the 10 network and from the core there goes my LAN where switches are cascaded.My problem is i'm having slow connection accessing from 10.x.x.x to 192.x.x.x network vice versa. what are the possible solutions is applicable, or the things I should check. plus I can't access(configure) my switches which is on the 192 network from 10.x.x.x. network through web.

Here's my setup:
1. 15mbps comcast xfinity cable broadband connection
2. Motorola cable modem
3. Netgear wireless router
4. Dell Inspiron 1520 w/ Intel PRO/Wireless 3945ABG
5. Windows XP
When I plugin with an ethernet cable to the router, I have no problems and I get the full 15mbps speed when doing speed tests and downloads. IE, Firefox, and Chrome all work fine.When I use the wireless, I only get 5mbps in IE and Firefox, but I get the full 15mbps again when using Chrome.I'm starting to wonder if there are shared Windows components being used by Firefox and IE, but not being used by Chrome. I have reinstalled my wireless adapter driver and it didn't affect anything. I've disabled Windows Firewall, checked for malware, confirmed no proxy was setup in Internet Options, on and on...

Normally use internet explorer 9, but I've tried Firefox and Chrome also.For some weird reason the Wi-Fi on my computer is super slow. My roommate has no problems at all. Same issue when only one of us are connected. What's really weird is that it's only on my home network the speed is a problem. At school and at other family members houses everything is working perfectly. I now use wired internet connection, and when I take a speedtest it is around 13MB, so the speed is pretty good.
I can mention that sometimes if my computer has been closed and the cable is taken out, when I turn the computer back on the Wi-Fi is suddenly working perfectly. Only for a while though, and then it's not working anymore. Has happened more rarely recently.I've been having this problem for around 7weeks now. When I first discovered the problem I tried to uninstall the latest updates (among windows updates), and it actually worked. But I want my computer to be up to date, so it's not a go to use those settings.
I have tried to reset the router to factory settings, but that did not work.We share internet with our landlord, so to privatize what we do, it's set up like this: Landlords modem -> switch in our apartment -> wireless router But that should not be problem. It's working on everyone else's computers. My mobile phone as no issues either;I've tried to update the driver on the wireless card, but it's up to date.

We have been having a very abnormal speed issue. This one has me stumped. I am fed up and thinking maybe its an Att issue that will NEVER be resolved.Brother comes and bothers me Zach internet is slow thinking hes just being picky I tell him to reboot his computer. He says its still slow. I run a speed test from my desktop computer I get a 5.36Mbps download and .63 up. I go to his windows xp professional laptop and run a speed test he pulls .63mbps down and .32 up. This is a Dell Latitude D610 with built in wifi. My desktop just so happens to be a wired connectionI grab my laptop which happens to be the exact same model and experience the same result. So I power cycle to modem, then the Linksys ea2700 router. The speeds go back to 5.37m down and normal speed up. Then after 20 minutes its back to a CRAWL.
OK the router MUST be dead. I will kill two birds with one stone. I plug in my Modem/Router combo 2wire 2700. Speed does the same thing starts off fast then slow to a crawl. Figuring it's a laptop issue I use a Linksys wireless USB adapter AE-2500. I get the same result fast then slow. NOW the crazy thing is that its only on my wireless connections. The wireless computers use wireless G and say 54mbps so why would the internet be slow only on the wireless connection.So maybe it's an interference issue So I start up the generator and plug my modem router and laptop into it. I then shut off THE ENTIRE POWER service to my house! I get the same result fast then slow. My neighbors are far apart and I have switched wireless channels and even used the 5ghz frequency with the same results.An ATT Tech says the line is fine. They came to the house and tested everything. The only thing that has happened recently was a storm which left flooding in some parts of town. Only one time was I able to test my WIRED computer and get a download speed of .04Mbps down and .32 up

A while ago internet access was slowed right down for an hour or so. I have a phone line that comes into the house and then into gateway (10.0.0.2) then ethernet from that to linksys wifi router (192.168.1.1). So I did the following ping and repeated what you see below a few times to see that these results were broadly consistent, which was the case. One other person is connected to linksys via ethernet cord and they might have been on at the time. Questions are.... are these results consistent with contention caused by other user on the linksys? and why can I ping gateway but not the router? That makes no sense to me! I am not annoyed with the other person if he is hogging the network...I like him. I just wonder whats going on. When the internet works results from pinging are all as one would expect

Today I set up a home network:Cable router plugged in to......Homeplug network, (D-Link DHP-307AV/B 200 MBPS PowerLine Homeplugs) plugged in to a LAN port of......a spare adsl router configured as per here: Connecting Additional Routers | Tech Support Forum...with two desktop machines plugged into the LAN ports of the ADSL router.Both of the desktops have got similar specs, are equi-distant from the ADSL router, and are both connected using Ethernet, not wireless.One of them gets a 9MB/sec ADSL [URL]download, the other can't even bring the webpage up and times out if you ask Google to do a search.Taking out the adsl router and plugging the desktop straight into the homeplug gets a network speed of ~13MB/sec on [URL].Plugging a computer directly into the cable modem gives network speeds of ~40MB/sec on [URL] How can I improve on this, and have it so that both machines can access the Interwebnet at a decent bandwidth?

I have been having problems with my Internet the past couple weeks. If I am watching a video, it doesn't matter which site, the video will stop and start from the beginning or the video will just stop altogether and I have to refresh the page. Another problem that happens while browsing, it will take about a minute for a page to load. The computer I am using is wired right into the router.
The rest of the family's computers the apple tv and the roku are wireless. I have been hearing complaints from them and have witnessed the laggyness. While streaming videos on the roku or apple tv, the video will stop and say video is not available or no connection. This is what I get from ipconfig/all

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...

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 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?

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.

I'm building my own home server based on Ubuntu with 4 drives in RAID 10. Its primary purpose will be NAS and backup.Would I be making a terrible mistake by building a NAS Server with a single Gigabit NIC?
I know the absolute max I can get out of a single Gigabit port is 125MB/s, and I want this NAS to be able to handle up to 6 computers accessing files simultaneously, with up to two of them streaming video.
With Ubuntu NIC-bonding and the performance of RAID 10, I can theoretically double my throughput and achieve 250MB/s (ok, not really, but it would be faster). The drives have an average read throughput of 83.87MB/s according to Tom's Hardware.
The unit itself will be based on the Chenbro ES34069-BK-180 case. With my current hardware choices, it'll have this motherboard with a Core i3 CPU and 8GB of RAM. Overkill, I know, but this server will be doing other things as well (like transcoding video).Unfortunately, the only Mini-ITX boards I can find with dual-gigabit and 6 SATA ports are Intel Atom-based, and I need more processing power than an Atom has to offer.
I would love to find a board with 6 SATA ports and two Gigabit LAN ports that supports a Core i3 CPU. So far, my search has come up empty. Thus, my dilemma.Should I hold out for such a board, go with an Atom-based solution, or stick with my current single-gigabit configuration?
I know there are consumer NAS units with just one gigabit interface (probably most of them), but I think I will demand a lot more from my server than the average home user.

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've been looking at picking up a 16-24 port gigabit switch that supports trunking, vlans etc. for home use.
I've looked at the Cisco SG2/300's, HP 1810g-24 and the Dell 2816 and 2824 switches, and it seems like the Cisco's are the best buy (layer 3'ish features, same price as the HP) but there isn't much about them.

I have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:
- The E3000 has a 192.168.0.6 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a 192.168.0.7 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the 192.168.0.1 as the gateway and web-interface
Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.
- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the 192.168.1.15 and 192.168.1.16 IPs and ports 9001 and 9002.
- The printer is connected to the E3000 and I have manually assigned the IP 192.168.1.30.
Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as 192.168.0.6 (E3000 IP), Internal Port 0, Public Interface IP (0.0.0.0), Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.
Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)
Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).

Here's the layout: Cable modem in the basement. Several devices in which I'd prefer a wired connection in the basement. Upstairs on the 1st and 2nd floor of the house are many devices in which wifi is fine or preferred.Here's the problem: As you might guess, wifi is weak upstairs and certainly on the patio and 2nd floor. I have an access point upstairs that I've experimented with but it is flaky.

I am a new student in networking, taking the CCNA courses, and now want to rewire my home. I currently have a cable modem and E2500 setup running my network. I want to get the modem and router out of my computer room and in the basement where the cable enters the house. I want to do this to clean up the computer room wiring a bit and to run line drops to different rooms in the house where the internet will be utilized.Currently there are two PC's, a laptop, a tablet, sometimes a phone, and an XBOX using the internet. I want to get my printer back up and running on the network but thats another story. Only one PC is currently hardwired. I would like to run two cables into the room with the PC and XBOX that are currently using wireless, at least two into the computer room for the PC and network printer, and one or two into the living room for the blue ray player and possibly an internet tv.
