Win 8.1 & W520 Intel wifi woes

Is anyone else having issues with win 8.1 and their W520's Intel wireless? In my case I have the Centrino N 6205, and the latest drivers from Intel (the Intel driver installer is version 16.6, but curiously the driver shown in the device manager is 15.10.4.2).
The issue I have is that the connection drops several times daily, and can only be reestablished by turning the wireless router on and off. There is no other way to reestablish it! Rebooting the W520 doesn't even work. By contrast, wireless when this same W520 is running Ubuntu is rock solid.
It's really quite frustrating. I certainly get tired of having to reenter the WPA2 password every time using the anemic win 8.1 network GUI. It has me contemplating the time consuming step of wiping win 8.1 & reinstalling win 7.
Thoughts?

Use another computer. Download the full feature software and drivers here.

T61, T60 - BSOD for Intel WiFi cards, Middleton BIOS, & Win 8.1 & 10

This is an "all-in-one" post. Recently, my trusty T61p started getting Blue Screens of Death (BSOD) with the following message:
DRIVER_IRQL_NOT_LESS_OR_EQAL in sysnetwlv64.sys This has been frequently reported as a complication of Windows 8.1 (only) when installing the Intel drivers for the 3945 and 4965 WiFi cards. Both Intel and Microsoft state that these cards, plus the 5200 are no longer supported, but the 6200, 6300, etc. are. Suggested remedies are:
1. For the T61's, reflash with the Middleton BIOS (2.29 plus mods - no white list, SATA 2 works). Then install a more recent WiFi card that has supported drivers for Win 8.1.
2. Change cards in both the T60 and T61s to the IBM/Lenovo ThinkPad 11a/b/g/n Wireless LAN Mini-PCI Express Adapter 42T0825 (this is an Atheros AR5008 5418 AR5BXB72). In recent posts I have seen about Win 10, the old Intel drivers that used to work for Win 8.0 (but didn't in 8.1) appear to work in Win 10. (However, since it is still before July 29, I can only assume this is in preview versions, not RTM). If anyone has actually in installed the Win 10 RTM and had no problems, this whole thing may be a "non-issue". Is there any experience with this? If I follow the remedies suggested above:
1. Using the replace the card approach with the Middleton BIOS, what is a good card to get? The other benefit of the Middleton BIOS is to allow the harddrives in the T-61's as SATA 2 instead of the dumbed-down SATA 1 as in the stock 2.29, 2.30 BIOS
2. If I follow the replace with the Atheros cards, I assume the best approach is to see if there are 3 antennas in the T60 (the T61's already have them). If not, I understand that I can add the 3rd antenna with FRU 42R9909. For specific machine configurations, see the specs at the bottom (they're all "FrankenPads").

I'd say go with Middleton BIOS either way (SATA II). In which case, get a newfangled 802.11ac card while you're at it.

[W520] Intel PROset/Wireless interferes with wifi connections

W520 with Windows 7 Pro and Intel Centrino N-6300 wireless adapter connecting to an Asus RT-N66U wireless router.
If I have Intel PROset/Wireless installed my laptop can't connect to any wifi networks. If I try the Windows network troubleshooter it thinks there is a problem with the access point but there isn't because I have a phone and 2 other laptops that can connect just fine. Restarting my computer or my router doesn't help, neither does uninstalling and resinstalling the wireless adapter drivers.. As soon as I uninstall PROset/Wireless I can connect again.
I've had this problem for quite a while and I just uninstall the software. I installed a bunch of Lenovo updates recently and it got installed again and I had a frustrating hour or so trying to troubleshoot until I remembered the likely cause of the problem. I uninstalled it and now things are working again. I don't think there are any features in the PROset/Wireless software I would even use but I'd still like to know why it's causing this problem.

Problem with Win 7 x64, WWAN or WiFi card and Windows XP Mode

I have a T500 with switchable graphics (2056-4RU) with a clean install of Windows 7 Pro x64 with the AT&T WWAN card.
With all the Win7 RTM drivers and Access Connections for Win7, I had a problem that the WWAN card (Ericson F3507g, purchased from Lenovo and working flawlessly under Vista 32-bit) would not initialize. Support told me to uninstall the Win 7 versions of the Power Manager Drivers, WWAN card driver and Access Connections and replace them with the Vista counterparts, which restored the functionality of my WWAN card. Based on the speed with which the support tech came up with the suggested fix, I suspect I am not the only one with the disappearing WWAN card problem.
Now I have found that starting the Windows XP Mode virtual machine kills the WiFi functionality (Intel WiFi Link 5100 AGN) until I disable and re-enable the WiFi adapter in Device Manager and then restart the system. (I have not problems with XP Mode and with the Win7 drivers / Access Connections opening Windows XP Mode did not cause the problem with the WiFi.) Opening Windows XP Mode causes no problem with the wired network adapter on my system).
Thus it appears that I can have functionality of the WWAN and WiFi adapters with XP Mode using the Released Win 7 versions and functionality of Windows XP Mode together OR I can have WWAN but not WiFi functionality with XP Mode using the Vista drivers that support suggested. However, it seems that I cannot have WWAN, WiFi and XP Mode concurrently.
I reproduced the above XP mode / WWAN problem / WiFi problems on a T500 with Win7 x64 owned by another family member.
Does anyone (particularly anyone from Lenovo) have fix for this?
Thanks.

for the sim card, try this:
http://jack.ukleja.com/update-ericsson-f3507g-mobile-broadband-on-windows-7-with-lenovo-thinkpad/com...
I have another operator and I finally gave up. apparently it's also no that easy to install the SIM card, if the plastic thing that helps to remove the SIM card is not the right position, it will overlap the SIM Card chip.
can't help for the WIFI. I had the problems too with access connection and decided to remove it. I use Seven's network manager, which does an equally good job.
Since I have the switch to turn off the wireless, I don't really need access connection anyway.
Finally, something that I learns while struggling with the bluetooth driver: the order in which power manager, access connection and the different drivers are installed DOES affect their effectiveness. I forgot the details but I remember 2 things:
always read the TXT file that is available on the driver page on the lenovo web site and install power manager and access connection last.
Good luck

New Intel WIFI Link Driver Randomly cut off Internet Connection

Two day ago I used ThinkVantage SYstem Update and installed Intel Wifi link driver (ver 13.01.1000). But since then my computer was randomly cut off internet connection, and the wireless signal strength icon on the system tray indicated no nearby wireless network. And then it powered off the wireless connection. Whatever I do, I cannot re-power on the wireless (I used Access Connection to power on the 802.11 wireless radio, but it could not be turned on and nothing happened) unless I restart the computer.
I thought it might be the router that malfunctioned as this problem never happened before. But after I checked the router and used another notebook to test wireless connection, I was sure the router ran very well.
Then I re-installed the TVT Access Connection (ver 5.61) and the Intel WIFI Link Driver (ver 13.01.1000) but the problem remained. Could anybody give a possible solution?
I also noticed on Lenovo's website, the Intel wireless card driver for T61 is v13.00.0000 Windows Vista 23 Oct 2009. It's lower than what I have now. Could that be the cause?
My ThinkPad T61 has the following configuration:
Model: T61 8897CTO
OS: WinVista Home Basic SP2 32bit
Language: EN
Wireless Card: Intel 3945 ABG
Wireless Card Driver: 13.1.1.1 (previous one was 13.0.0.0)
TVT Access Connection: 5.61
Solved!

Hi carlven,
Anytime when wireless driver is updated, Access Connections also needs to be reistalled.
Do this, first uninstall your wireless driver and access connections, thereafter reboot your system. Then install wireless driver first, again reboot, subsequently install access connections, reboot again.
When installing any lenovo driver manually, keep in mind they first extract themselves to a default location in C:\Drivers..., second .exe setup must be run from that location to successfully install the drivers.
Hope it helps.

W500 Intel wifi Link 5300 AGN- No N?

I have a W500 with Win 7 x64. I have the Intel wifi link 5300 AGN wireless card and the Intel drivers, 14.3.2.1
In Device Manager, Advanced tab, it shows those settings for 802.11n properties. But at the bottom of the list, Wireless Mode, it only shows 802.11a/b/g. There is no N mode. Is this card capable of N speeds wirelessly? Thank you for your help.
Solved!
Go to Solution.

"N" isn't a specific mode you set on the wireless card, the options should be various mixtures of A, B, and G listed.
802.11B and 802.11G are both in the 2.4Ghz range, which everything and it's brother uses including microwaves, cordless phones, etc. So it's very noisy, but common. 802.11G is the higher-speed version of 802.11B; if anything on given wireless frequency 'channel' only supports 802.11B, everything on that channel is limited to 802.11B.
A is in the 5.0Ghz range, and 802.11A is the *ONLY* thing there; it's also a much lesser-used standard, you need specific wireless routers that support it, etc. If you can use it, do so.
802.11n is actually an 'upgrade' to the others, allowing multi-channel bonding, and very wide channels, both of which increase bandwidth a LOT.
But for example on both my T61p and W530 my "Wireless Mode" options are: a, b, g, b/g, a/g, a/b/g. I have a separate "802.11n Mode" option of enabled/disabled in the Advanced tab on my wireless card.

T540p battery drain in S4 state after Bios and Intel Wifi driver update

Hey Guys,
on my T540p, I configured the rapid start technology according to
http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days.
I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to
https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Battery-drain-when-powered-down-Y410P/td-p...
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
How could this battery drain be avoided? Has anybody experienced the same issue?
Best,
Martin

mka1284,
you could check out devices that might resume laptop from the sleep modes and disable them. Type in the following command in the cmd line window:
powercfg -devicequery wake_armed
Also the following command will show you report about power management. Open cmd window with administrative rights and type in:
powercfg -energy.

Is upgrading the Intel WiFi Link 5300 driver ourselves permitted?

I obtained my T400 in November, and notice that the driver for my Intel WiFi Link 5300 wireless adapter is version 12.1.0.14 from 8/28/08.
On the Intel Web site, I've noticed that the driver was upgraded to 12.1.2.1 on 11/24/08:
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&Inst=Yes&ProductID=3062&DwnldID=17163&strOSs=...
Are we permitted to install the latest driver (including the Intel PROSet/Wireless WiFi Connection Utility for Windows Vista, or does this interfere with ThinkVantage Wireless Detection, etc.), or do we have to wait to see if Lenovo certifies this version?
Thanks in advance,
Mike

I think I might have figured it out. There are two PCI Express Mini Card slots on the T400S (2801). The shorter slot is for WiFi/WiMax cards and the longer slot is for WAN cards. The longer 5300 cards on the market cannot be used in the longer slot. Windows recognizes the cards but Access Connections (or maybe the BIOS) does not allow it to operate. Can anyone verify this?
Yes, that seems to be the case. I don't have a T400s but I do have the long Intel Wifi Link 5300 card FRU 43Y6495 in my x200. The WWAN slot is the same size as the WLAN slot on my x200. However, as you have discovered, the WLAN slot and WWAN on the T400s are different sizes. A quick check of pgs. 71-74, sections 1050 and 1060 of the T400s Hardware Maintenance Manual indicates that a half-height wifi card must be used in the half-height WLAN slot and evidently you cannot use one of the long wifi cards by utilizing the WWAN slot. So for example the Intel wifi Link 5300 card FRU 43Y6495 cannot work in your T400 but the half-height version of the Intel Wifi Link 5300 card FRU 43Y6519 would work as noted in T400s System Service Parts here. You also have a few other wifi choices listed for your type "2801" T400s.
Have a great day. (I do not work for Lenovo)

Intel wifi not working | U series 450P

Hi,
I believe my notebook ran out of battery and shut off during an system update. I rebooted and found the wireless internet connection to not work along with the ethernet connection not working. I restored my system to a date prior to the last update. The system resotored so that i could access the internet but only with an ethernet cord. The wireless is still broken.
I just downloaded the intel wifi driver from lenovos site, these were already on my system but i overrode them and downloaded all new drivers. I still cant find my home network which my roomates are able to access. My computer doesnt even pick up the network signal.
What do i do to access the internet using wireless?
Please advise
Thanks

Wireless Problem in windows 7 intel wifi link 5100agn

i bought a dv7 1270us laptop in january. everything was fine until the last 3 months i started having small problems in vista. it would take 10+ minutes to connect and the speed would go up and down. then i installed windows 7 and am either having problems with the card or driver but ive tried every driver i can find and nithing has worked.. the wireless drops randonly. when it drops it doesnt lose connection the signal drops all the way down to one bar and i get maybe 10Kbps of bandwith well it takes 2 minutes to load a page of this forum atleast. When it drops it also only drops for maybe 5-10 minutes or else it stays like that until i restart but resarting always fixes it tempoparily for 10 minutes or so. toaday i tried to disconnect and reconnect to my network. as soon as i cicked connect i got a blue screen it pointed torwards netw5v64.sys i have tried re installing the drivers multiple times and the problem isnt resolved. i have sent the laptop in twice in the last 2 months one for the blue ray drive and wireless problems i am having now. they sent it back with a new blue ray drive and a new antenna for my wireless saying the card was fina it was a driver and maybe a new antenna would help with connectivity. well they were wrong. i got it back and it started overheating to 90+ degrees celcius and wireless problems were still there even though they re-imaged the hard drive so all drivers should be perfect.so i sent it back again. now i just got it back and they cleaned the heatsink and completely ignored my wireless problems. the sheet that states the repairs that were done has a circle aroubd cleaned heatsink/fan and thats it n comments or anything. then to make the icing on the cake there is a 3 inch long fairly deep scrath on my laptop i take verygood care of all of my laptops so that i can sell them used for more than a scratched up one. i am very disappointed in hp and almost dont want to send it back and loose it for another week just to get it back without anything being done again i am almost certain they would re0image the hard drive again and send it back since they didnt even do that the second time. okay back on topic is there anything anyone has heard t fix this so i dont have to send it in again. any help is appreciated

Intel! They make processors and a variety of motherboard hardware, but they seem to have a devil of a time making decent drivers. Particularly with their wireless NICs. Lately I’ve noticed a number of errors springing from the Intel WiFi Link 5100/5300 AGN family of wireless adapters. They seem to cause random bluescreen errors on Windows Vista systems. Fortnuately, there is a viable workaround:
-Right click on Computer and select Manage.
-After Computer Management opens up, go to Device Manager.
-In Device Manager, expand the Network Adapters category.
-Right-click on “Intel (R) WiFi Link 5100 AGN” and select Properties.
-In Properties, go to the Power Management tab.
-Under the Power Management tab, make sure that “Allow the computer to turn off this device to save power” is unchecked.
Apparently, the driver for the WiFi Link 5100 can’t properly handle the device going to sleep, and pulls down the whole system. Hopefully Intel will fix this in future driver updates. Until then, this workaround will have to do.

T500 Intel Wifi 5350 is unable to connect automatically with Windows 8.1

Hello, I have searched the forums to see if there is a similar problem like the one I am having, but, did not come across. I bought my T500 in 2009 with XP installed. I have recently installed Windows 8.1 and started to experience problems with my Intel Wifi 5350. Upon restart, the driver is unable to connect to my home wifi. In order to connect, I need to go through trouble shooting and reset the wifi link, which, then, fixes the problem. When I first installed Windows 8.1, I did not have this problem. It seemed to have happened after a few auto updates.
The driver software I have is 13.3.0.137 with a date of 8/15/2010. Driver provider is Microsoft.
I downloaded but not yet installed Intel® PROSet/Wireless Software for Windows 8.1 Wireless_17.1.0_De164.exe. I am not sure if this will fix it. I wanted to ask this first before I do something. If you have had this before or know the answer, could you please post specific links to which drivers I should install manually? Thanks! I appreciate if you could be specific in your responses as I am not super tech savvy.

When I press Fn+F5 I get the charms bar as attached in my 1st post, but not a popup

Intel wifi link 1000 series, how to get it working?

Hi, I have installed arch linux on my netbook acer 1825PTZ, its wireless card is Intel wifi link 1000series, I have tried to follow the wireless setup guide on archwiki but I have not come to a conclusion...I've searched among the list of supported drivers but I am not sure if it is supported or not. So can you plz make a more accurate research? i would like to keep ndiswrapper as ultimate choice...

Ehh... can dmesg without any options actually enable anything? Anyway, I post this in case you still get some issues.
natostanco wrote:ehm, how I am supposed to download a package if i am installing the device for internet connection? I thought that the package was already between installation files...
Hopefully you will be able to use ethernet, or you could download the linux-firmware package from a mirror on a different system.
To download the package from a mirror without pacman, go to one of the HTTP addresses in /etc/pacman.d/mirrorlist with "$repo" swapped with "core" and $arch swapped with either i686 or x86_64. You should be able to see a link to a linux-firmware file. When you've transferred this file over to your Arch system, you install it by
# pacman -U /path/to/package
I avoided the Netinstall image as I suspected that I would have some major issues getting Internet connectivity. If you chose the core image, you should have the package already installed.

New Intel WIFI Wireless Network Adapter does not recognize Wireless Router

I have had a Linksys BEFW11S4 Version 4 Wireless router for quite some time. It works like a champ and I have one Laptop wired to it and a second using Wireless working just fine. Recently, I received a new ThinkPad W500 Laptop with an Intel WIFI Link 5100 AGN wireless network adapter. The older laptop that works just fine with the router uses a
11a/b/g Wireless LAN Mini PCI Express Adapter by Atheros. However, the NEW laptop with the Intel Adapter fails to connect to the Router. It will either indicate a failure while "Waiting for Association" or it will indicate a failure when waiting to "renew IP Address". Sometimes, it will show a signal strength close to ZERO (Even as the older laptop with the other adapter is showing a signal strength close to 100%) When I called Linksys support, I was told that the facts that the Router (a) works find with the wired Laptop and (b) works fine with the 11a/b/g NEtwork Adapter and (c) works fine when WIRED to the new laptop all indicate that the problem is NOT with the router at all -- but with the Network Adapter. Can anyone tell me what has to be adjusted in the Adapter settings? Right now, I am using IBM Access Connections for BOTH of the wireless laptops. I have made sure to set IDENTICAL values for SSID and WEP (128-bit) [static] password. I have also ensured that all OTHER settings are the same for the two laptops. Yet, in one laptop, there is NO PROBLEM while in the other, I can not get the Wireless Adapter to "see" the signal from the Router. TO further check this, I have [temporarily] disabled the WEP password, enabled SSID broadcast, and disabled the MAC address restrictions that I put in (so that the system would be totally "open") yet the Intel Adapter STILL did not "find" anything. In addition, when I use the "Find WIFI" feature in Access Connections, I find that SOMETIMES the network with SSID is found and sometimes, it will display "unknown network" and not pick up the SSID.
This is all very frustrating. If anyone has experience with the Intel WIFI Link 5100 AGN Adapter, I would appreciate any hints, tricks, ideas, etc.
Think you!!!!
--Zvi

I installed the LATEST version of IBM Access Connections as well as verifying that I have teh LATEST drivers for the Intel Wireless NEtwork Adapter.
What now happens is that I am able to authenticate to the Router. However, I get a failure on "renewing IP Address" -- which [according to the diagnostic message] means that the Rotuer fails to provide me with an IP address to use. Do you have any suggestions?

Wifi Upgrade to Intel Wifi Link 5300

I bought my Lenovo T500 last year in summer (2009). It came with a b/g wifi card and I want to upgrade it to Intel Wifi Link 5300 but it seems lenovo.com has stopped selling this card. I also heard that not all 5300 cards are compatible with Lenovo Thinkpads. Could anyone tell me if this card is compatible or not? If not, any suggestions?

Thank You.

you still can get this part from IBM parts in USA. Those card on the Amazon and Ebay are not from Lenovo, therefore they are will not work in the machines without a modified bios.
