Lenovo W540 poor network performance

My company recently purchased a Lenovo W540 (Intel i7-4700MQ @ 2.4 Ghz, 16 GB RAM, Windows 8.1 pro 64-bit) for me to use when I am working remote. I have to say that this thing has been an albatross from day one. While it generally performs poorly, the wifi is the worst I have ever experienced. The W540 can only hit a fraction of the network speeds of my 4-year-old Dell Latitude E6400 (1.1 Mbps compared to 2.7 Mpbs on average). The connectivity is very unreliable and I am constantly losing my VPN and VoIP connections.
I have updated all of the drivers available from Lenovo and Intel as well as removed most of the bloatware pre-installed from Lenovo. Prior to doing so I could only manage .6 Mbps on a good day - using my tethered 3G phone was faster and more reliable.
I have contacted support twice to gain assistance. Their best offer was to have me drive an hour to the nearest service center for support.
I am at my wit's end and would appreciate any assistance you can offer before I send this back to Lenovo along with a jar of vasaline.
Solved!
Go to Solution.

Try uninstalling the wifi drivers from device manager before re-installing the latest version. My Intel 6300 card was sticking at 54mbps the other day too, and this seemed to fix it.

Very poor network performance with a G4

I have a white & grey G4 (1.25GHz and 256MB) running OS X 10.4.5. It's exhibiting very poor network performance, e.g. it will not FTP files over a LAN at more than about 40KB/second.
Other nodes on the same switch perform fine, as do other ports on the switch. The machine is set to autodetect for speed & duplex, so my question is -- how do I debug this? I've tried swapping network cables already...
Thanks!
Chris

This came down to an incompatibility between the G4 and the Cisco. When the switch is set to force 100Mbit but negotiate duplex, the G4 doesn't like it. Going back to auto speed & duplex fixed the problem...

Poor Network Performance from VPN sites

We are experiencing poor network performance when connecting from hardware VPN sites. VPN sites have Cisco Hardware VPN client 3002 which terminates to Cisco 3005 VPN concentrator. Geting upload/download speeds of 355/484kbsp from VPN to surewest.com. If I remove the VPN and connect laptop directly to dsl modem, speeds are 3mb up and 1mb down. Any ideas what could be causing this?

Try this
Adjust the MTU and MSS size in concentrator and client.

Extremly poor network performance

Hello all. First time post, please excuse any annoyances.
I'm using a WRT300N Wireless-N Broadband Router connecting three (sometimes four) computers. Two wired and one (sometimes two) wireless, using 802.11G.
After a long period of time or after a short period of extremely high use (usually bit-torrenting assorted files) my network performance crawls to a near stop. My laptop will show an "excellent" connection but the speed will be 1 Mbps. The wired computers still show a connection of 100 Mbps but cannot connect to anything, including the router (using the web configure site). All connections time out. This happens to all the computers connected at the time and the only cure I've found thus far is to restart the router and or modem. If you need any more information please ask. Below is the information of my router, computers hooked to the router, and the network connection coming in.
Connection coming in the house:
Comcast Cable. 6 Meg connection (download)
Router:
WRT300N Wireless-N Broadband Router
Using the latest firmware (0.93.3)
Using DHCP, Laptop1 and Desktop1 have reservations.
Laptop1:
Broadcom internal wireless 'card' running 802.11G
Desktop 1:
Intel NIC
Desktop 2:
Asus motherboard onboard NIC
(occasional) Laptop2:
Dell external wireless card running 802.11G

I must apologize for one annoyance... the whole post. I skipped step one of posting by forgetting to use that handy-dandy "Search" box located just above this whole post deal, I apologize again. I've found (after searching) that this problem is actually quite common with the 300N and I assume it's a firmware issue, I then assume that Linksys is working day and night, sweating behind a monitor, sleepless and hungry because all they are doing is trying to resolve this issue... then again... you know what they say about 'assuming''.

SOLVED:Poor networking performance (Slow site lookup)

I am dual booting with Windoze on the same machine. Websurfing performance on Arch is poor, and I can't figure out why. Windoze surfing with Firefox is instantaneous, whereas on Arch, I get "looking up http:www.google.com....................." for a good 5 seconds, sometimes 10 or 20 seconds, or more.
It will be fine for a few minutes, and then I get pretty bad stalls like that quite often.
Heres my rc.conf networking section:
lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
And my daemons:
DAEMONS=(@syslog-ng @hal @network @netfs @crond @alsa @fam @portmap kdm)
Any ideas?

You might try adding "alias net-pf-10 off" to /etc/modprobe.conf.
Tried this, and it did not work. Same lag when "looking up" sights.

The way I have it set up in my system, and works like a charm, is that I have the nameserver set in the router and in my system.
Ok, this seems to have worked. I plugged the DNS ip entries into the router and my resolv.conf, but DHCPD rewrites the resolv.conf on each reboot. I will consult the wiki to correct that, but even with just the DNS info in the router alone, I tried it out for a good 10 minutes and it was zippy fast, just like Windoze and PCLinuxOS (on my other HD).
I will wait a day before renaming the thread as "SOLVED", so I can test ouit the results more thoroughly.
Now, can anyone explain why it works fast under Windoze and PCLinuxOS, but Arch needs the DNS settings? Or is it just one of those weird unexplainable things?
I am using a D-Link router, if it matters. (IIRC, some routers actually use Linux.)

Hyper-V Windows 2012 r2 Poor network performance

Hi,
Since that I installed Windows 2012 R2 and Hyper-v, I notice that is very slow performing copy operations from the VMs to the physical machine (appears to be lock to 10MB). Firs I though that this issue was only between the VMs and the parent OS, now I realized
that when copying between this Hyper-v physical host and another physical host in the same subnet I also get only 10MB of speed.
How do I unlock this 10MB limit??
The switch and all NICs are GIGABIT capable and before using Windows 2012 r2, using the same hardware boxes I was doing 400MB of transfers between physical hosts and VMs??!!
Thank you.

I had the exact same issue with the same AR8151 NIC on my Alienware, only I'm running Windows 8.1.
I have a VM with both an external (to the AR8151) and an internal NIC which serves as both a domain controller and router (RRAS) for my other VMs (which only have Internal interfaces). There is no VMQ setting on the adapter, and I messed around with
the offload/RSS settings, but performance would drop whenever this VM would be running. (Internet speed test would go from 95Mbps downstream to about 24Mbps.). When I paused or shut down the VM, performance would return to normal.
I found the issue to be an errant entry in my route table which I have no idea how it happened. A second default route was created which used the internal IP of the VM with a lower metric. Simply deleting the route corrected the performance issue.

Lenovo T420s Poor Battery/Performance

Hi, so I recently bought a used T420s off ebay. Everything is going swimmingly with the exception of the battery that came included was almost dead.
The specs of the laptop:
- Core i7-2620M
- Intel HD 3000 / Nvidia NVs 4200m
- 8GB 1333mhz
- Samsung 240GB SSD
I just purchased a new battery along with the ultrabay battery. With full charge on both, I am only getting 3 hours at most with the lowest brightness. I am no beginning with installing software, and reformatting myself with Windows 7, and I believe I have all the non-bloatware software. So I don't believe I have any software that is making the computer waste battery. This problem persists when I used integrated graphics only.
One thing I have noticed is that my computer gets really hot, even when just watching netflix, it will peak 100 degrees celcius, the video will lag and the audio will become distorted at that point. One possible solution I had in mind was that the thermal pads used with the heatsink are worn out and am planning on replacing with my own thermal paste when I have the time.
Anyone have any other possible solutions or theory behind what may be causing this problem? Or is this just a common problem with T420s? Thanks!

Hi
I am T420s end user, but I am using I5 CPU,
All of we know i7 is not suitalbe for s series, since the s series design is too small for make the hot air out soon.
You better way is first try to upgrade your BIOS first see can fix it or not.
Then on power model choose Balanced Mode in your Windows.
If all not work, try send back the machine to the ebay within refund date. And buy a T420s with i5 CPU, this one will not run very hot, until you choose high performance mode let it run at full speed few hour.
About the s series battery life. it gneral only can work at balance mode about 2:30 to 3:00 hour is gneral. Don't beleive the AD said can 10 hours etc. No notebook can do like this, expect Mac Notebook with real big battery.
Hope this help.

Poor network performance on wired ethernet port and airport

I'm using Leopard 10.5.1 on a home network comprised of a new, fully up-to-date (firmware wise) D-link wireless router and a couple ethernet hubs. I initially had problems because of old router firmware, but buying the new router and making sure firmware was up-to-date seems to have solved the connection problems. What I now experience is that whichever network cennection I am using, wireless or wired ethernet port, will slow down so slow that it's impossible to get any web content, upload files to my local server, or sent emails with any kind of attachment. Turning off the connection I am using, either wired ethernet or airport, and switching to the other solves the problem for a short time, usually a couple days or so. Then that connection with slow down and I have to switch back - again solving the problem. So to keep my network connection alive, I have to keep switching back and forth between the wired ethernet and the airport connection.
The rest of my network consists of several Windows machines including a Windows 2000 server. None of these devices ever have any problems with network access.
I've tried playing with the advanced settings with no luck. Does anyone know of a specific setting that might be the culprit?

Hi ,
Maybe you can try to disable checksum offloading and jumbo frames on the Physical NIC (ESX platform) to check result .

Poor network performance in busy areas of San Francisco

Verizon LTE coverage seems to be very poor in certain parts of San Francisco. The connection seems ok at 2 or 3 bars on 4g, but data connections are very slow. In particular along 18th street between Church and Castro, and Castro Street from Market to 20th, and finally the North East side of Corona Heights park. I have a Galaxy S5, I've tried resetting a few times. Also, I've been walking with others on verizon that have the same issue, as well as people on other carriers that didn't. Any hope of seeing better coverage in the near future in those areas? There are several people considering switching over this.

Post a URL so we can test the page.
My "guess" is that Flash is the video format and Snow Leopard (10.6) actually installs an "out of date" version (fixed with the 10.6.1 update).

Poor network performance with Websockets running on apple device

I am working on an HTML/Javascript running on mobile devices that is communicating with a Qt/C++ application running on a PC. Both the mobile device and the PC are on a local network. The communication between the HTML page (client) and the C++ app (server) is done using Websockets.
The HTML page is a remote control for the C++ application, so it is needed to have a low latency connection between the mobile device and the PC.
When using any non-Apple device as a client, data is sent to a rate between 60 to 120 frames/sec, which is totally acceptable. When using an Apple device, this rate falls to 3-4 frames/sec. I also checked ping times (Websocket implementation, not a ping command from command line). They are acceptable (1-5 ms) for Apple devices as long as the device is not transmitting data. Whenever it transmits data, this ping time raises to 200ms.
Looking from the Javascript side, the Apple devices always send data at a consistent rate of 60 frames/sec, as any other devices do. However, on the server side, only 3 to 4 of these 60 frames are received when the client is an Apple device.
Does anyone have any idea on what can be happening?
Here is my Javascript code :
<script language="javascript" type="text/javascript">
        var wsUri = document.URL.replace("http", "ws");
        var output;
        var websocket;
        function init()
            output = document.getElementById("output");
            wsConnect();
        function wsConnect()
            console.log("Trying connection to " + wsUri);
            try
                output = document.getElementById("output");
                websocket = new WebSocket(wsUri);
                websocket.onopen = function(evt)
                        onOpen(evt)
                websocket.onclose = function(evt)
                        onClose(evt)
                websocket.onmessage = function(evt)
                        onMessage(evt)
                websocket.onerror = function(evt)
                        onError(evt)
            catch (e)
                console.log("Exception " + e.toString());
        function onOpen(evt)
            alert("Connected to " + wsUri);
        function onClose(evt)
            alert("Disconnected");
        function onMessage(evt)
            alert('Received message : ' + evt.data);
        function onError(evt)
            alert("Error : " + evt.toString());
        function doSend(message)
            websocket.send(message);
        window.addEventListener("load", init, false);
</script>
Data is sent from Javascript side using dosend() function.

What version of websocket is your server using? That is pretty much on the bleeding edge of things. It looks like you need to use RFC6455 and iOS6 and it should work fine.
Thanks for the post. I didn't know about websockets. Very interesting.

I have recently upgraded my ipad mini to iOS 6.0.2 and still have poor wifi performance. My 3rd generation ipad works great on the same network. I have done all the resets I can think of but nothing helps. I would not have purchased the mini had I known.

On the same wifi network, third generation ipad, iphone4s and MacBook Pro work just fine. The ipad mini often can not connect with the mail server and seems to hang a long time trying to open a web page. Had I known the mini had this kind of difficulty on wifi, I would have reconsidered my purchase. I have tried resetting the network and renewing the lease on the mini in addition. To completing the most current iOS upgrade. Still poor wifi performance. Unacceptable, in my opinion.

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

Macbook Pro 11,2 tests very poor WiFi performance compared to iPad

Configuration:
MBP 11,2 running 10.10.1
Airport Express 2014 vintage
WiFi Scanner.app speed test results on MBP range from 1 to 3 Mbps. My iPad Air (or iPad Mini) in the same physical position tests between 18 and 28 Mbps. WiFi Scanner.app shows SNR of 17 to 18 dbm.
The reason I am testing is because I have noticed network performance on the new MBP to be very poor in our current NZ location. In Palo Alto 2 weeks ago the MBP wifi seemed fine - I didn't bother to test.
Any suggestions would be much appreciated!

Hello .Sup,

Poor 3G performance from Hutchinson 3 Service Provide at HK

any Hong Kong 3G iphone users experiencing poor 3G performance on Hutchinson 3 network? test my 3G iphone against original EDGE iphone at same spot on office floor, browsing to www.yahoo.com and the performance was marginally quicker than EDGE. after calling our service provide, being told that we were capped on network bandwidth of 7.2mbps but the real speed testing was around 0.3mbps.... this is unacceptable performance.
Apple - please speak to vendor, this is making your product look BAD.

Dismal Network Performance

Hello,
I have a brand new (one week old) Mac Mini. It is able to see/connect to the wireless network just fine - however packetloss runs in the 40-60% range and ping times were well over 500ms. After experimentation I decided that the location of the Mini was not desirable and purchased a Linksys 802.11n Wireless Ethernet Bridge (aka the gaming adapter) to use. The Bridge is connected to the mini via an Ethernet cable to the Mini's network port. This configuration resolved the packet loss, and I see strong signal back to the wireless router - however network performance is still dismal (200 KBps file transfers localy to the Mini). MacBook, MacBookPro, Dell Laptop are all using the same wireless network and can transfer files without problem (2-4 MBps) even when placed in the same location as the Mini.
Reading through the forums there were some hints about disabiling IPv6 which I have done. I cannot imagine this is OSX specific given the other Macs on my network... which only leaves the Mini, which is even stranger given the performance issues on both the Wireless and Wired network interfaces.
What else should I look at? Is this just a "bad" box?
Thanks in advance,
Max
Specific Details
Mac Mini (New)
OS 10.5.8
Airport Extreme Basestation
I have a brand new (one week old) Mac Mini running 10.5.8

I have the exact same issue. I just moved into a new home and my Mac Mini doesn't pick up the network very well at all. To solve this issue, I have to buy a separate usb "N" wifi adapter to use instead of the built in airport card for the fix ($35 at NewEgg.com).
http://www.newegg.com/Product/Product.aspx?Item=N82E16833166025
The Mac Mini has horrible reception for all wireless frequencies at my house with (b/g/n). I'm using a crappy Dell running XP with a usb "G" adapter sharing it's wired ethernet to my MacMini to access the internet now through a linksys WRT54G. I bought the AirPort Extreme Base Station to try to use the "N" speeds with all the great reviews I've read about it lately and it works just as bad with the linksys WRT54G using the Mac Mini. My "MacBook" performs EXCELLENT with the linksys and the apple router. My junky dell performs EXCELLENT with both routers also. Every computer in the house (4) loves either router except the poor Mac Mini. I have moved every desktop and laptop to where my Mac Mini exists and they all get great reception (EXCEPT THE MAC MINI).
Conclusion:
MacMini: Very Bad wireless reception
MacBook: Best wireless reception of all computers with both routers.
Dell w/Netgear wireless "G" adapter: Good reception where Mac Mini is located.
IBM NetVista: Great Wireless Reception on "G" network with Linksys
HP Tower of somekind: Great Wireless Reception on "G" network with linksys.
With the Airport Extreme "N" and the Linksis "B/G" WRT54G the Airport smokes it. Plus the shared harddrive and printing is awesome.
