Windows 7 64 bit wireless latency

I have been struggling with an odd issue effecting openvpn on Windows 7 64-bit wireless. Performance is very sluggish and my ping latency is very high across the openvpn connection when compared to WinXP wireless and Win7 wired connections.
This appears to be an issue with the Intel WiFi Link 1000 BGN wireless card. No firmware updates are available from Lenovo or Intel for the card.
Average ping latency is 30ms across vpn from WinXP in both wireless and wired as well as Win7 wired. But goes to 130ms+ from Win7 wireless connection! This translates to a remote session that is like working through molasses. Stepping through code in Visual Studio on a remote machine from the Windows 7 machine when on a wireless connection has so much lag time it becomes unusable. Making the remote connection on a wired ethernet or WinXP wireless N is as responsive as sitting in front of the remote machine.
Appears that my MTU is optimal for my internet connection. I tested and found that 1480 is the minimum size packet where I can ping and return a "Packet needs to be fragmented but DF set." response. So I am leaving my MTU at 1500 on both wired and wireless on Win7 machine.
So far I have (I believe) ruled out the following:
Firewalls - both windows and at router - have turned off both with no effect
Antivirus - no change with it deactivated
Router settings - put laptop in DMZ and no change
MTU - tested 1500 as optimal
Thinkpad drivers and BIOS - all latest
Has anyone else run into issues with this Intel 1000 wireless card?
Thanks,
Jeff

Go to Solution.

I had a real problem with wireless performance on multiple ThinkPads with Win7 until I realized there is a new (or maybe changed implementation) power setting in Win7 which was affecting it.
If you go into Control Panel -> Power Options and click "Change plan settings" for your current power plan.
On the next screen click on "Change advanced power settings"
On the next screen expand "Wireless Adapter Settings" and then "Power Saving Mode"
Make sure it is set to Maximum Performance.
Not sure if this will help your particular problem but hope it does.

Linksys Smart Wi-Fi Device List Not Finding Windows 8 Wireless Adapter

I recently upgraded my Wi-Fi router to an EA3500 and am controlling it using Smart Wi-Fi running on a wired Windows 7 machine.
So far, I have been able to add devices to the network without issue and each of those connections works fine. All, except my TV, have been Windows 7 based machines.  Smart Wi-Fi Device List has been able to "see" each device and I have been able to add them to that list as well.
I am attempting to add a Windows 8 desktop computer to the network which is using a external USB wireless adapter. That computer can see and connect to the network through the EA3500 and the connection seems to work fine. The only issue is that its adapter does not show up in the Device List.
My questions:
1) Does the Device List do anything else besides showing a list of devices I chosen to add to my network?
2) How do I get my Windows 8 wireless adapter to show up in the Device List?
Thanks In Adance!
Solved!

Try the following:
1.       Disconnect the computer from the wireless network
2.       Remove wireless network profile on your computer
3.       Reboot the computer and power cycle the router
4.       Reconnect to the wireless network
5.       Check if the computer shows up on the device list.
If it is still not showing, reset and reconfigure the wireless router.

Windows laptops wireless access to the Internet and not to any of my files?

TC late 2008. I want to give Windows laptops wireless access to the Internet and not to any of my files? I have tried to locate "Guest" accounts in my Airport Utility with no luck and I do not understand my options. Example: Could I add a Linksys Wireless-G Cable Gateway router before or after my TC and not have a security problem?

Welcome to Apple's discussion groups.
Guest networking requires a "simultaneous dual-band" AirPort Extreme or Time Capsule. Those weren't introduced until 2009.
Are the files you want to protect on your Time Capsule or on your Mac? You can protect files on your Time Capsule with a password. In AirPort Utility look at the Disks panel, File Sharing tab.

Although I am an HP employee, I am speaking for myself and not for HP

Hello,
I have a mini 210-1080NR. Due to a software problem I had to reinstall the OS. I now have Win 7 Prof working fine on it. When trying to connect ot the Internet, I get the WLAN module is not present. I tried installing the "SP48755" WLAN driver. It did not work. I also opened the bottom cover, removed the WLAN module and reconnected to reseat and show a new piece of hardare was installed. This did not resolve the issue.
So, in Device Manager, the following problems display :
1 - Network Controller (apparently precents me from connecting to the Internet)
2 - Video Controller (no display issues, except my resolution only goes to 1024.
Per instructions of a Forum HP tech before, I went to the Details tab (first line) for both Network Controller and Video Controller and copied the Hardware IDs:
Network Controller:
PCI\VEN_14E4&DEV_4357&SUBSYS_145E103C&REV_01
PCI\VEN_14E4&DEV_4357&SUBSYS_145E103C

I suspect the Video Controller issue will be resolved once I connect to the Internet and update the OS and hardware drivers.

Linksys Wireless Network monitor overrides Windows XP Wireless Zero Configuration

Hello all,
I am currently using the wireless router Verizon sent me and it works fine when using the Windows XP Wireless Zero Configuration tool. Previously I was using a Linksys wireless router and I have the Linksys Wireless Network monitor installed. About half the time when starting up the computer, the Linksys monitor starts up and I have to manually switch to the Windows XP Wireless Zero Configuration tool. This is very irritating and I would like to know if there is a way I can remove the Linksys Monitor and still be able to use the Linksys wireless adapter cards installed in the computer.

I think I know.
#1 http://netsquirrel.com/msconfig/msconfig_xp.html
#2 Very carefully, look through the list in MSConfig.
#3 Disable the Linksys Wireless Network monitor.
Restart the computer as need be.

Ideapad z710 windows 7 wireless issue

Hello. First of all, I would like to say I love how great the products lenovo puts out there.
Second of all, I am frustrated. I just purchased a Lenovo z710 and dualbooted with Windows 7 since Windows 8 was my primary OS (ew).
So I downloaded all of the drivers necessary for the Windows 7 OS, and all of them work...but my wireless.
I am running the 64bit model of 7. I cannot get the wireless driver to work or "install" Much help would be appreciated!!
Solved!
Go to Solution.

There was a long thread on one of the boards here that was about the exact same issue but on a different laptop.
Turned out the problem was UEFI, but they were doing it with an SSD. In there case UEFI had to be updated.
But there is another thread specifically with your exact same issues.
https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/ideapad-z710-windows-7-wireless/td-p/12718...
There are some solutions there that may work for you.
As for the company not caring about any software other than windows 8, if you get right down to it, the system worked perfectly well with the supplied OS, it was your choice to downgrade. Did you check to see if this was possible before purchasing the system? I feel the same way as most of you probably do, I like Windows 7 much more than Windows 8. Windows 8.1 is kind of a median version between the two. If you don't have a touch screen, it still is not fun. But Windows 7 mainstream support ends in January and extended support dies in January 2020. That means after January you will have to pay Microsoft to get help with windows. If you look around you will find that ALL manufacturers have either totally stop selling systems with Windows 7 or are pretty close to it. And I can assure you after January they will stop all sales of Windows 7. At that point if there are not drivers for your devices, chances are pretty good there never will be. Very few OEM's continue writing drivers for operating systems that are in the process of being phased out.

Deskjet 2610 disconnection and lights flashing, Windows 7 64 bit, wireless router

I have a Deskjet 2610xi All in One printer that is connected with an ethernet cord to my Netgear wireless router. I am using two Toshiba laptops both running Windows 7 64 bit and both are connected wirelessly. I did not have any problems printing before I installed the new HP Solution Center Software and the fix for Windows 7 connectivity problems from the HP website.
I installed the new driver because I couldn't use my old cd and driver from my original puchase to install the HP software on our new Toshiba laptops. After installing the new driver and software, I now had the functionality of the HP Solution Center and I could now scan, copy etc. with the new software. Not too long after that, my printer started disconnecting and all the lights would flash. The screen on the printer shows error 0x887dd03a. If I press the start button, I can get the printer reconnected for a short amount of time and my print jobs will go through, but it always goes back to the flashing.
I ran the HP Solution Center software to check for updates and was notified of the critical update for Windows 7 reliability. I installed the update, but the problem still exists.
I searched posts on this forum and one of them told me to allow the printers to be shared on the homegroup, which I did, but the problem still exists. I then found another post that told me to do a semi-full reset on my printer, which I did, but the problem still exists.
As mentioned earlier, my printer works as long as I press the start button to get the printer connected again, but it goes back to the error message and flashing lights again. I would like to keep the new software since it allows me to scan without being hardwired to my printer, but if I have to uninstall it, could someone please explain how I can scan documents on the printer directly to my computers wirelessly?
Also, I don't understand the whole Homegroup, Workgroup and Network Sharing settings, etc. so if that is the issue, please walk me through it step by step. I am not sure what the settings are now.
FYI, I went to my Devices and Printers and I see HP Photosmart 2600 series and HP Photosmart 2600 series (2) icons. The one for series (2) is the one checkmarked on both computers.
I am not a computer whiz and so I would appreciate any responses to be very basic. I have done all the research I can and still have the problem described.
Thanks in advance for your help!

Windows 7 64-bit & wireless Palm Zire 72 - can't sync?

We've loaded the software that came with the Zire 72 on our new Dell Inspiron 1750 laptop however we can't sync. I went to Palm's website and downloaded/installed Palm Desktop 6.2 as it said it was for 64-bit systems however we STILL can't sync.
I got to the step on the Palm unit where it asks for the Security code which I entered but it still does not want to sync.
Does anyone have any answers to this secret? We are connecting via Bluetooth.
UPDATE: I'm now seeing the message about the port being used when we try to hotsync.
Thanks very much!

Thinkpad X200 Vista Business 32-bit Wireless network problems

Hey guys!
I seem to have a persistent problem with my two Lenovo Thinkpad X200, which I simply can't manage to figure it.
I have recently restored the computers to factory settings, which meant downgrading from Windows 8 to Windows Vista Business 32-Bit.
Now, everything with the installation went as planned until I had to test if everything was working. A lot of the drivers seem to be missing and since I do not still have the original manufacturer's disc, I do not know what to do.
I downloaded the ethernet driver from Lenovo's website and that is now fully functional.
I have also tried everything in regards to making the wireless internet work, but without any luck. When I try connecting to the wireless internet, Windows simply can't detect any networks and when I try using Windows function to find a solution to the problem it simply says "This computer does not have a wireless network adapter installed and configured".
I have tried downloading all the wireless lan driver for Windows Vista 32-bit from Lenovo's website, but I still cannot get the wireless network to work.
Any help would be highly appreciated
Thank you in advance

Intel Wireless-N 7260 Slow Internet Speed - Solved (Win 8.1 64-bit, Wireless N @ 2.4GHz)

Obviously there are numerous factors that can affect speed. But if you have reason to believe it's just your laptop try the configuration below. Worked for me. Good Luck.
Laptop:
Lenovo Ideapad Y510P, Windows 8.1 64-bit.
Internet Connection:
Comcast Xfinity Blast advertised at 50Mbps.
Network Environment:
Home Wifi, Linksys E1500 Router Wireless N @ 2.4 GHz. Firmware Version: 1.0.06
Apartment Building, ~15 visible other Wifi networks.
Devices with 15 feet of router.
Problem Symptoms:
Download speeds of 2-3 Mbps. Upload speeds were typically much higher, around 10Mbps as should be expected.
Control Reference:
~50Mbps using ethernet cable.
Older Laptop getting ~45Mbps over Wifi.
Solution:
From what I gathered, the problem with the card happens on Wireless N 2.4MHz routers.
Driver version : 17.13.2.2
File : Wireless_17.13.2_De164.zip
Downloaded from : http://goo.gl/S3HOCL (Intel download page. URL was too long to post)
Installation : Unzip to a folder, Run the DPInst64.exe application - does a 'simple' driver install. No Bloatware / fluff.
Device Settings: I'm listing only the values that I changed along the way.
Device Manager > Network Adapters > Intel(R) Wireless-N 7260 > Properties > Advanced.
802.11n Channel Width for 2.4GHz : Auto
Ad Hoc Qos Mode : WMM Disabled
HT Mode : HT Mode (ie ON. You need this for Wireless N. If Disabled you can only connect to Wireless b/g/mixed)
Roaming Aggressiveness : 1. Lowest
Throughput Booster : Enabled (Not sure if this is necessary. It's an optional feature giving priority over other devices)
Transmit Power : 3. Medium
U-APSD Support : Disabled (According to numerous posts, this is critical)
Wireless Router Wireless Settings:
Network Mode : Wireless-N Only
Channel Width : 20 MHz Only. (My only other option is 'Auto (20 MHz or 40 MHz). On 'Auto...' every device I have really slows).
Channel : Auto (I had this set to '3' since day one to avoid the channels other Routers in my building are using. Defintely noticed improvement but it seems its not necessary with this configuration. Could be due to other networks not being used at the time of testing. I'm keeping an eye on this).
Bluetooth Network Connection (Personal Area Network):
Disabled
(I have a running bluetooth mouse which is not affected by disabling this)
Result:
Testing duration 6 hours, ~ 10 times.
For the settings. most likely there's some that are not necessary. But after working on this for 3 days, I'm not changing anything for the time being.
Blurb:
I'm posting this to hopefully help others who have this issue. Researching the problem I found numerous lengthy fourm threads filled with frustrated users...one on Intel's support site was 18 pages long with literally months of posts with several users discussing a class action lawsuit...enough said.
I tried pretty much all the posted solutions, lots of different driver versions, device settings, router settings. There's so much misinformation out there it's not funny. Eventually I called Lenovo Tech Support who tried simialr things and momentarily got it a bit better and wanted to say it was fixed. I hung on a kept testing the slow speed soon returned. Then they tried all the usual nonsense and excuses and gave up, passing me off to "Premium Support:" who wanted to charge me to investigate the problem. The "premium" techs were really poor and sounded like a bunch of clueless hacks just trying to get you to pay for the service while simultaneously throwing in gems like "how far is your laptop from the router...that can affect your speed"...anyway, forget that I thought.
When I first got the Lenovo Ideapad Y510P last year I had the same or similar issue. I don't recall how I fixed it then but I got it to ~20-30Mbps. While well below my older laptop's speed it was perfectly adequate. That was last August. Earlier this year there was an update for Intels stuff in a Windows update. I think the problem started again with that although I'm not 100% sure. Certainly I didn't manually install new drivers or change anything on my network set-up.

Intel Wireless-N 7260 works at only 2.4Ghz. Refer the specifications of this wireless card:

HP C4480 Windows 7 wireless finds printer but won't print to it

I have a 3 PC network with a Cisco wireless router. My C4480 is connected to a wired desktop running Windows 7 64 bit with updated HP drivers for the printer. I have shared the printer, both directly and using the Homegroup. I can connect to the printer with a wired XP desktop.
However, I cannot connect to it with my Windows 7 32 bit laptop. The laptop finds it when I set up the homegroup, and I can see it in the device display. However, nothing prints. I also followed a suggestion on the Microsoft site, and set up a local port for the printer, mapping it directly to the desktop PC and printer. Again, the printer is found, and displays (and yes, I've turned off the homegroup printer sharing on both the desktop and the laptop).
But it still doesn't print.
Any suggestions are appreciated!

I'm a bit confused about why you are using a print server with a printer that has built-in ethernet?
(Built-in ethernet means it has a built-in print server. The major problem you are having is that the HP/OS X driver for this printer uses Bonjour (Bonjour Only) to communicate with the built-in print server. Since you've added an extra layer with the print server, I doubt that the HP driver will work.)
Just figured it out - you need the printer in a location that isn't convenient for ethernet, right.
Some choices - There is an open source driver, foo2hp, plus ESP ghostscript plus Foomatic-rip:
http://www.linuxprinting.org/showprinter.cgi?recnum=HP-Color_LaserJet2600n
http://www.linuxprinting.org/macosx/foomatic/
Or, try some kind of wireless to ethernet bridge (so you can use the built-in print server and driver).
Or, get a different printer.

Windows 7 Wireless and Audio Drivers on 2010 MacBook Pro

I have a new MacBook Pro i7 2.66 Mhz with Snow Leopard and dual boot to Windows 7 64 bit Ultimate. I can't find the correct drivers (Windows 7 side) to get the audio and the wireless networking operating. I ran the bootcamp setup from the Snow Leopard install disc on Windows 7. It gave an error message that this model is not supported. I then ran each software driver individually from the install disc and was able to get all to work except the audio and wireless. I then installed the Bootcamp 3.2 update from the Internet with no improvement.
Does anybody know where the audio and wireless drivers can be located for Windows 7? (Apple Support has not been able to resolve the problem yet) Thank You!

I'm having the same problem with Windows 7 64-bit Professional. I had to go through the same process to get most of the drivers installed. I've had the same issues with the wireless and audio drivers.
To get the Apple drivers installed, I followed the instructions from this blog post.

Has anyone had any luck with the rest of the drivers?

Solaris 10 x86 64-bit wireless connection problem

I installed Solaris 10 x86 32-bit on my laptop together with Fedora 10 (Linux) and Windows XP.
When I boot up Fedora 10 and WinXP, these two OS are able to find the wireless driver automatically, but Solaris 10 failed.
When I do prtconf -pv, I saw my wireless card is listed in the output.
So I update the /boot/solaris/devicedb/master and /etc/driver_aliases with my wireless card id - pci168c,001a
Then do sys-unconfig and reboot
But after reboot, Solaris still only tries to configure the ethernet card (NIC) rather than checking out the wireless connection.
I think this might be a design flaw for Solaris 10. If it runs on x86, most users would have wireless connection, not just land line connection.
Does anyone here have a solution for this problem?
Thanks a lot!

I assume that when solaris 10 boots up, it only checks the land line NIC card, not the wireless card. If there is no lan connection, then so be it.
Is that right?No! :-)
nwam only supports one device but the device is selectable. physical should activate all devices regardless. So if your Wifi isn't working then I would use wificonfig to see what it can see. Check the man page for scan and showstatus options. Then you'll know what it's seeing.

Unusual wireless latency and speed issue

I have an odd problem where wireless connections to the home hub 3 will start to exhibit very high and varied latency from 40ms up to 1000ms every 15 to 30 seconds (pinging from laptop to homehub) and slow throughput of about 4Mbit. The link speed is solid at 144Mbit/sec and the signal is always on maximum.
If I change the wireless channel on the router and the change it back to its original value the connection starts to behave and latency is normally 1-3ms with the odd spike up to 90 or so and realworld throughput jumps up to 60+Mbit/sec.
I suspected packet fragmentation back have confirmed this is not the case and now believe it to be a problem with the home hub as restarting it or changing the wireless channel will fix the issue for a few hours. Anyone else had this problem and resolved it? It is a pain because the connection does still work but it makes streaming high quality media impossible and online gaming becomes a pain with constant lag until I poke the router.

I assume you're using windows vista, 7 and it probably affects windows 8 as well.
When you're connected wirelessly, it never stops searching for a wireless connection and briefly disconnects you from the one you are connect to.
You can turn this off with a program called WLAN Optimizer.
