Intel 5100 on t500

So it seems the adapter is acting up. It sees networking n linux it refuses to obtain an ip adress. Windows 7 sees the network will connect sometimes but has a slooooooow connection and sometimes won't load the page. Other times it won't connect.
I use another computer on same network and the internal adapter works fine. It seem's other people are reporting the same problem.
Has anybody heard of this problem or have a possible fix?
Solved!
Go to Solution.

pretty easy just take off the palmrest and then the keyboard, you will see a wifi card under the keyboard area.
you still have to use similar card, maybe get the Intel 5300.
Also it must be from a Lenovo ThinkPad, otherwise you would get an error on the laptop.

[Solved] Wired connection ok but wireless problem on Intel 5100

Here is how i solved the problem :
1 - get back to the wiki doing everything in order
2 - added dbus in attition to hal in the deamon line in rc.conf
3 - put wicd at the end of the deamon line
4 - then configured wicd for my wireless network at boot : no more dbus error, and connection perfectly ok
Thx very much for the superb wiki, certainly my fault if i messed up but i still have to learn
Hi
I've got a problem with the wireless connection on my toshiba R10
my wired connection is working flawlessly but i can't use my wifi card. I'm using arch 2009.8 i686
Here is what i've done following the wiki :
1 : installed ifplugd for the RJ45 connection + added the deamon on my rc.conf
2 : installed wireless-tools
3 : installed the driver intel 5100
# pacman -S iwlwifi-5000-ucode
set up my mod_autolog yes
here is my ifconfig -a

I suspect that something is wrong between iwlagn and iwlwifi-5000 which can cause this problem.
I have to say that I'm quite lost here, i hope someone will have an idea
thank you very much

Stab in the dark...the hal daemon should start dbus, but sometimes I've been encouraged to add the dbus DAEMON explicitly (before hal).
I don't really understand dbus too intimately, but I've come across situations where although dbus is running, I can't talk to it because the DBUS_SESSION_BUS_{ADDRESS,PID,WINDOWID} variables weren't visible in the environment I was working in. For instance, if dbus is started by xinitrc, and then some system-level daemon tries to talk to dbus, usually it fails for me, and I have to use some workaround.
Now I would expect wicd to be set up so that the ordinary user doesn't encounter any problems of this sort. On the other hand, the error you're getting does say that it's dbus communication which is failing. Perhaps you could try shutting down hald and dbus, open a terminal, su -, /etc/rc.d/dbus start, and then try from that command line to tell wicd to connect?

Intel 5100-5300 getting packet loss with a wrt 310n

Hi All
I have found a fix for this and it seems to work for me. Intel 5100 worked fine with a dlink but I always recieved packet loss with my wrt 310n
http://www.intel.com/support/wireless/wlan/sb/cs-006205.htm
Just though I would Hare it with the Community
Regards
Wall

I have an ASUS UX32VD-DB71 which has the Intel Centrino 6235 wifi card. I've been having this laptop for more than 6 months and I've tried different solutions to fix the issue with Wireless-N but none of them were stable other than disabling N completely using 11n_disable=1
I've tried different kernels all the way from 3.2 to the latest 3.7 series of kernels (both in the openSUSE tree as well as mainline) with no luck whasoever. I also tried installing the compat-drivers from 2013-01-23-1-u version onto my 3.6 kernel which provided the same results too. I see packet loss with N and the G speeds are just too slow. I have a workstation in my network and I can only transfer effectively at 1.5 MB /s max over G whereas an old laptop from 2007 which has an 1x1 MIMO antenna (again Intel though) can connect at 144 Mbps to my router and transfer files at least 3-4 times faster (if not more).
It is totally unacceptable for Intel to not just fix this issue for Linux.

T400 Intel 5100 AGN help!

Hi,
I recently installed Windows 7 and I have been experiencing slow internet speed ever since. I have already updated the drivers for both network adapters (Intel Wifi Link 5100 AGN ver 12.4 1.4 and the Intenl 82567LF Gigabet Network Connection ver 10.0.2.2). I used to be able to recieve 6mb/s for downloads, but now it has been reduced to less than 1 mb/s.
Here is my speed test:
http://www.speedtest.net/result/616886714.png
Are there other drivers or software that I need to update to get my speed back?
Thanks

Probably completely unrelated but maybe not...
I just put a test install of Win 7 Pro 64 on my T400 w/Intel 5100. It was running Vista Biz 64 and working fine with my Linksys N router. With '7 it wouldn't see the router most of the time, would occasionally see it and associate sometimes, and always drop in a few seconds.
The "fix" was to enable QoS in the router. Absolutely no idea why.

Replacing my Intel 5100 AGN card with a Intel 2200 (X200 Thinkpad)

Hi there,
Does anyone knows if this will work ?
I'm planning to change the 5100 AGN card with an old Intel 2200 model because I want to play with OSX86 on my X200.

Intel 5100 AGN replacement with an Intel 5300 AGN

I have an Intel WiFi 5100 and I was told to purchase a 5300 card as a replacement. The laptop starts, but stops and tells me that there is unregistered hardware trying to start and windows will stop it immediatley. HOW DO I INSTALL THE NEW DRIVERS for a presplash screen in windows 7?

I have an HP Pavilion DV7-2185dx and the Intel website was the one who directed me to the 5300 saying it was more stable and even though the third antenna connection would be open, the performance would more than make up for the lose of the WiFi extentended distance. AND just so you know: This network adapter had been working fine for years and years with little or no issues, then about 6 months ago it started to act up, dropping the signal and just working slowly. I tried, but was unsucecessful in downloading and installing the up to the minute drivers for this 5100. And finally, this is the mindblower: The card works extremely and without fault under the Ubuntu OS. I switched from W7 to U11 with the dual boot and NO ISSUES! SO, I believe it is something that MS has done with their many, many updates that come over constantly. They must have updated something else and screwed up the Intel drivers. If you look online, you will see hundreds of people with the same or similar issues that remain unresolved since 2011, with the only resolution being the use of a USB Network Key, of which I always had as a backup and troubleshooting device. So, before you look to chastise me for listening to an Intel tech, perhaps you should read the thousands of angry customers who have had their NIC go bad and HP and Intel have NO **bleep** ANSWER!!! Some crap, to say the least... PS...As I said the card works WONDERFULLY using UBUNTU 11, so I don't believe it is the card, but rather the software that is controlling it.

Satellite L350-171: Question about Draft N in Wlan card Intel 5100

Recently swapped to this machine after having fun with a P300.
My question is this; under the properties of the 5100 in Device Manager, there is an option to enable draft-n, but draft-n is not a option to select in the wireless mode.
Is draft-n a auto selection or am I missing something?

In my Intel WLan driver the Draft N is also not available in wireless mode.
There are only settings fro the A b or G. But the 802.11 N mode is enabled.
If this setting is enabled then your WLan will support the high throughput mode (MINO 802.11n)
So if your WLan router supports and provides the Draft N feature then your WLan card should choose it automatically.
PS; Please ensure that you are using the latest WLan driver from the Intel page!

Any help is really appreciated.

It's a shame the bug isn't titled properly so it shows up when clicking the "Search Bug Reports" on our linux package page ._.
No ..this not solve problem for intel wifi card ..it's another problem.
I idem have this problem and only solution found is ...change hardware (wifi card ) ..now work ok.

Intel 5100 stop working occasionally

OS: happend both on Vista Home Basic and XP SP3
Machine: X200
Driver:
happened both with Lenovo pre-install and Intel new driver
happened both w/ or w/o Access Connection
Wireless Router:
ordinary router that I used for a few years. all other notebook/desktop works fine with it.
Problem:
1) sometimes the network just stops working, though the icon may still indicate connection
2) sometimes after standby the network cannot resume without rebooting
What's done, and doesn't seem to make difference:
Disable power saving in the property sheet of wireless adapter, in device manager
Disable power saving on wireless in Lenovo Power Manager
Any insight?
Thanks.

I have same problem and done everything tech support could tell me and they sent someone and changed the card but still have same problem. After many calls to tech and sale I had to order and pay for a new machine and they are suppose to take this back. Although I paid for new machine I have not received return authorization yet.

U350 / Intel 5100 AGN problems

I have a u350 w/ windows 7 and I'm getting poor wifi speed, packet loss, and disconnections.
I have a good Cisco AP (802.11g) that works well with my two other laptops. Typically sitting side by side, the other laptops will be at 54 or 48 mbps and will download a 700mb file about twice as fast from a local file server. I've had the ap and other laptops for months and never got disconected in my own house before, but I have lost signal multiple times with the u350.
I also bought a crappy linksys wrt610n to go with the new u350, none of my other devices support N so I set this thing up exclusively for the u350. I typically get speeds anywhere from 2-5mbps on the N AP but sometimes as high as 24mbps. I've played with various settings on the AP such as 5ghz only, 2.4ghz, or both at the same time, but it's pretty crappy and slower than G every time.
Because I have the two APs, and the other laptops, I'm pretty sure it's just the u350 that's screwed up. Forgetting the 802.11n, I would be happy if I could use the u350 with my Cisco G without getting disconnected and dropping packets left and right.
Is it possible I have a bad wi-fi card or could it be just a software problem? I've tried both the lenovo driver and the newer intel/microsoft one and they both have this issue.
Solved!

Disregard this, I took it apart and found one of the antenna cables was loose. Now I'm getting 54mbps on G and 216mbps on N.

T400 with Intel 5100 : wireless-related crashes on Linux

Hi,
I just bought a T400 last month and installed Ubuntu Linux 8.10 (Intrepid Ibex) last week. The kernel version is 2.6.27 (right now it is 2.6.27-11.27). Most parts works wonderfully for me, yet I keep getting problems with the wireless card. Last week and this week I got the computer crashing on me when I was doing wireless-related stuff (mainly to bring up the wireless interface).
First problem (Feb 5, 2009)
I was waking the computer up from sleep (suspend) and trying to disable/enable wireless, etc.
Don't remember what I did; perhaps Fn+F5 and other keys as well. The computer suddenly hung by itself, and caps lock light blinking. I had to turn off the computer by holding the power switch.
After start, the wireless behaving strangely:
* before "ifconfig wlan0 up", the wireless light is off
* after "ifconfig wlan0 up", the wireless light is on
* after "ifconfig wlan0 down", the wireless light is off -- never like this before! Wireless light is usually always on all the time unless we press the Fn+F5 key.
* connection to my wireless ESSID network is not working.
* But in Vista the wireless connection is fine!
* reboot with Linux doesn't help.
I thought I was doomed for the wireless in linux. But when I used the hardware switch to turn off the wireless and turned it on again, the wireless suddenty worked again! But the wireless light behavior (turning off when I brought down the network interface) persists.
The second error (Feb 9, 2009)
I brought the computer up from sleep (suspend). The wireless switch was off at this point. With hardware wireless switch turned OFF (my mistake!), I tried to turn on the wireless interface (wlan0) using `ifup' program. When I did that, I encountered the following error:
Error for wireless request "Set ESSID" (8B1A):
   SET filed on device wlan0 ; Resource temporarily unavailable.
...(DHCP program's message)
wmaster0: unknown hardware address type 801.
...(trying to get IP address, which is futile)
Before this returns to shell, I turned on the wireless switch then ^C the ifup program. This is fine, I thought.
Then I ifdown the wlan0 and tried to ifup it again. Guess what happened? The computer hung again, the caps lock blinked. And the computer became useless until I force it to shutdown by holding the power switch.
The error message in /var/log/kern.log is not that helpful; there is nothing out of the ordinary:

Can somebody help me with this? Let me know if you want more technical information.
Since the first error I have booted back to WinVista and use the PC Doctor to see if there is something wrong with the card. But all tests returned fine. This is bizzare.

Thanks for posting your problem. So it is not an isolated issue with my laptop only. Let me ask a few questions:
* How often does your laptop crash? Like: roughly every week, or very rarely?
* What is the wireless card that you have? If you don't know, please type "lspci" from command prompt and post it here.
* What is your wireless network configuration? Do you use WEP, WPA, or WPA2?
While I still don't know what the problem is, this may help narrow down the occassion (and thus, the cause) of the problem.

Wifi failed to start on Intel 5100

New Linux user here, I hope to increase my skills rapidly.
I searched quite a while for a solution for this to no avail.
Wifi worked fine for me on installation but as soon as I rebooted, I received failure messages when trying to connect to my router.
When trying to access my router through wifi-menu, I recieve:
Job for netctl@wls1\x2d2WIRE740.service failed. See 'systemctl status netctl@wls1\x2d2WIRE740.service and journalctl -xn' for details.

Intel Wireless WiFi Link 5100 and Realtek ALC663

Hi,
does anyone use wifi card: Intel Wireless WiFi Link 5100
and/or soundcard: Realtek ALC663
and/or Graphics Adapter: NVIDIA GeForce 9650M GT?
Because I'd like to buy Asus X57VN:
: Processor
Intel Core 2 Duo P8400 2.26 GHz
:: Chipset
Intel PM45
:: RAM
3072 MB, DDR2-800, 2 GB + 1 GB
:: Graphics Adapter
NVIDIA GeForce 9650M GT - 1024 MB, core: 550 MHz, ram: 400 MHz, ForceWare 176.05
:: Matrix
15,4 Zoll 16:10, 1440x900 , AU Optronics B154PW02 V2 / AUO2277
:: Harddisk
320 GB - 5400 rpm, 320GB 5400, Hitachi HTS543232L9A300
:: Soundcard
Realtek ALC663
:: Slots
1 Express Card 54mm, 4 USB, 1 Firewire, 1 VGA, 1 HDMI, 56 kb/s Modem, 1 Kensington Lock, 1 eSata, Audio Connections: micro, headset, Card Reader: 8 w 1 (SD/MMC/MS/MS Pro),
:: Connectivity
Realtek RTL8168C/8111C Family PCI-E Gigabit Ethernet NIC , Intel Wireless WiFi Link 5100 , Bluetooth
And I want to know is some issue with hardware described above especially sound, wifi and grafics.
Previously I've had intel wifi 4965 and realtek ALC268. First use iwl4965-ucode (package) and module in kernel, second causing some issue: it was necessary to add "options snd_hda_intel model=acer" to /etc/modprobe.conf.
If anyone use that laptop or some of hardware, please describe me the details about it ( firmware, /etc/modprobe.conf or any incompatibles ).
I'm interested about:
-Does nvidia 177.82-1 driver support Geforce 9650M GT,
-Does iwlwifi-5000-ucode firmware and kernel module enough for Intel Wireless WiFi Link 5100 to work,
-Does Realtek ALC663 work smoothly (just alsa), or any /etc/modprobe.conf or /etc/modprobe.d/alsa-base options are necessary?
I'll be grateful.

I can answer about the wireless intel 5100 part. I've got an intel 5300 and it's working fine. The drivers are included in the 2.6.27 kernel so you just have to install the iwlwifi-5000-ucode firmware.

Using WRT610N w/ Intel WiFi Link 5100 wireless module

I am considering buying an FW or Z series Sony laptop which includes Intel WiFi Link 5100 as the wireless module, which is a dual range (2.4 & 5 GHz) 802.11 a/b/g/draft-n module. In order to benefit from wireless-n speeds as much as possible, I want to buy a good Wireless-N router. The one I am considering buying is Linksys WRT-610N. However, the thing is that I see on some forums that people have some problems with an older Linksys Wireless-N router used in conjunction with an older Intel wireless module. I am afraid I can have similar problem with the combination of the above mentioned router and wireless module. Moreover, I read a comment on somebody’s review of WRT610N on amazon.com that says that WRT610N is based on broadcom wireless chipset and thus may not give a good performance on PCs having an Atheros wireless module. If this is correct, it may go the same for using WRT610N with an Intel wireless chipset. Anyhow, my question is, have you been using a Linksys router with your PC that has an Intel wireless module and how do you find the performance (speed, range, frequency of drop-offs)? Comments from people using WRT610N (at least WRT600) along with a PC that has an Intel WiFi Link 5100 will be much more appreciated!

I think your in luck.. I have the exact combination that you are considering. I have a Sony FW190 with the intel 5100 a/g/draft-n card.
In my network I have the following:
1 Toshiba laptop 802.11abg (atheros)
1 Sony laptop 802.11abg (intel)
1 Sony FW190 802.11agn (Intel 5100)
I'm leveraging the dual radios on the wrt610n using 5Ghz band (wide) exclusively for the Sony FW190 the other laptops use the 2.4Ghz band.
On the Draft-N wifi connections I get connection speeds from 136Mbps to 300Mbps .. I've gotten donload speeds from my home server at a sustained 60Mbps+ speeds.
The configuration on both the laptop and the router took some understanding because of the features that 802.11n provides and the capability of the router to support dual radios. But overall I'm happy with the hardware and performance.
Good luck!

Regarding using wwan in T400 with Intel(R) WiFi Link 5100 AGN

Hello,
Im interested to use of WWAN in my laptop, My is Thinkpad T400, having with Intel(R) WiFi Link 5100 AGN.
please guide me with process accesing the simcard slot in laptop.
Waiting for your reply.
With Regards
Santhosh

Hi,
I believe the SIM card slot is in the battery bay. Remove the battery to access.
That Intel 5100 is a wifi card, not a wwan card. Do you also have a wwan card installed, or is that what you are asking about?
Information on both (SIM and wwan card installation) is in the hardware maintenance manual: Hardware Maintenance Manual - T400 & R400
