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!
Go to Solution.

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.

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.

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.

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.

Alternative to Intel Wifi Link 5100 AGN wireless network card?

I'm finding that my Intel 5100 AGN wireless network card is not performing as well as it used to. I've tried everything... even drivers are fully up to date. But I keep losing connection to my wireless router, even though connection strength is between 3-4 bars. I find that I rarely get dropped if I have 5 bars. But if it weakens to 3, I get periodically dropped no matter what wireless network I am using.
I want to replace this card with something better, but of course compatible with the HP dv5 (my specific model is dv5t-1000). Any recommendations?

Hi, Gary:
What I meant by my statement regarding you having the better of the available cards for your notebook is that, yes, I am sure the Intel 5300 is an improvement over the 5100, but the problem is you can't install the 5300 in your notebook.
The Intel 5300 is not supported (only the cards/part numbers listed in the service manual can be installed) and your notebook wouldn't boot until you removed the card.
You can try a different card listed in the manual if you want.
However, you are limited to the:
Broadcom 4322 802.11a/b/g/n WLAN module
Broadcom BCM4312 802.11b/g WLAN module (not a wireless N card)
I suppose you can use an external USB adapter but I would get one with an external antenna connected to it, because I would have to believe the 3 antenna wire setup in your notebook has to provide superior reception over a plain USB wireless adapter with an internal antenna as its only antenna.
The antennas go all the way up to the top of your screen.
Did you fiddle around with your network card's advanced settings? They can be found by clicking on the card in the device manager, clicking on the advanced tab. make a note of where the settings are now so if something goes buggy, you can change them back.
Here is a guide to the advanced settings you have and the recommended settings for them.

I am on version 1.0.04 and my wireless adapter Intel(R) WiFi Link 5100 AGN keeps disconnecting and reconnecting? Anyone with similar problems found a fix?

Is the wireless connection dropping on all the computers or only on one wireless computer?
Make sure that drivers of the wireless adapter are updated.

MSI GX640 Intel WiFi Link 5100 AGN dropping connection every ~10 minutes

Problem: Getting disconnected every 5-20 minutes. Network card: Intel WiFi Link 5100 AGN.
Solutions tried: Router restarted? No idea what to do, googling it yielded no viable results, even though I can't say I'm pro at googling. Found no drivers on MSI homepage.

Further information:
My MSI GX640 had problems with heating and was sent to be repaired and got its heatzink switched. I started getting disconnects every 10 minutes or so, sometimes less than a minute apart, sometimes up to 20 minutes without a disconnection.
Don't really know what information you might need, so please do tell if something is missing.

Those are not the newest: http://eu.msi.com/index.php?func=nbdriver&maincat_no=135&prod_no=1998
You'll get the newest at: http://www.intel.com/support/wireless/detect.htm - click the check buttom and follow steps. <- These are from 18-10-2010
But yeah you'll might need to change which wireless channels you are on. If you aren't using Wireless connection then you might have to check your LAN card drivers or this can allso be caused by your ISP or bad connection on your internet line.

Intel WiFi Link 5100 AGN not connecting

I am having an issue getting the Intel WiFi Link 5100 AGN on my HP Pavilion dv7-1275dx to connect to my wireless router (Zyxel P334WT). It would intermittently connect, then drops off for no apparent reason, and then refuses to connect for days. I contacted HP support and we spent three hours trying to fix the problem, to no avail. Strangely enough, when I stick my Netgear WG111v2 USB wireless adapter into the computer, I am able to connect to my network with no problem. The computer runs Windows Home Vista 64 bit. Thanks in advance for your help.

[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

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?

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

Problems connecting on Wireless 802.11n with my T61 with Intel Wireless AGN

Hi, I live in Thailand and have a similar problem as others with my Intel Wireless AGN connection as others. I have a D-Link Model DSL-2740B Rangebooster N ADSL2/2+ Modem Router. It is supposed to support 802.11n draft wireless connections of up to a maximum of 270 MBPS versus 54 MBPS for 802-11G wireless. Of course, I don't expect it to reach the maximum transfer speed, particularly here in Thaiand, however I would expect it to produce results better than the 54 MBPS rate for 802-11G. I first tried it on my ThinkPad T61 which incorporates Intel® Wireless WiFi Link 4965AGN. When connected, it shows a speed of 54MBPS (802-11G) instead of higher wireless 802-11n speeds. I've upgraded my router to the latest firmware and have tried different configurations with no improvement in performance. One think I have noted is that when I make an on-line configuration change to my router configuration then select "apply", immediately my ThinkPad rate changes to 150 MBPS momentarily then my connection is lost (to be expected as the router changes are being implemented), followed by reconnection of wireless signal only to return at 54 MBPS again. I also have an older ThinkPad model without built-in wireless capability so I purchased a Belkin wireless 802.11n USB adapter to connect to my router. Again, the maximum connection is at 54 MBPS. When I repeat configuration changes to my router as I did above, my ThinkPad connection momentarily changes to only 1 MBPS instead of 150 MBPS as in my other T61 ThinkPad then reverts back to 54 MBPS once the configuration changes have been completed. Has anyone successfully used wireless 802.11n successfully at the higher transfer rates (above 54 MBPS)? Is it possible that my TOT Goldcyber connection speed is artificially limited? I notice that my rated speed for my desktop computer connected to my same D-Link DSL-2740B only indicates a rated speed of 100 MBPS. I use Vista Home Premium 64-bit on my destop, Vista Home Premium 32-bit on my ThinkPad T61, but us Windows XP Professional on my older ThinkPad. I feel that my problem is either with my ADSL carrier (TOT) or compatibility with my D-Link DSL-2740B Modem Router and my ThinkPad T61 internal wireless card and/or Belkin wireless n USB adapter. IT-City is letting me swap out the Belkin USB for the D-Link Rangebooster n DWA-140 USB adapter next week when they restock. The only other think that I can think of is that wireless n just doesn't work in Thailand and that maybe I should just stick with wireless G and go with a higher powered wireless USB model such as the business rated EmGenius EUB 362 EXT. Has anyone used this model and had good success with it; I've heard that it is a long range model and has the capability of reaching 108 MBPS through some sort of magic? Looking forward to reading your replies and possible solution.
Pattayadavid

Hi!
Intel Wi-Fi cards support full 802.11n speed of 300 Mb/s working at 5 GHz range only. Your D-Link DSL-2740B works only in 2.4 GHz range. So to get 300 Mb/s you have to get another wi-fi router that supports 802.11n in both 2.4 and 5 GHz, for instance Lynksys WRT610N or Apple Airport Extreme or whatever.

If I pacman -U linux-3.1.4-1-x86_64.pkg.tar.xz, everything works again.
Any help is really appreciated.
Thanks.

Because in 3.1.5 there was a commit added to iwlwifi that breaks things and in 3.1.6 because our kernel maintainers haven't yet implemented the patch that fixes things in both 3.1.5 and 3.1.6: https://bugs.archlinux.org/task/27581 Revert to 3.1.4 or compile a new kernel with the linked patch.
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.

WRVS4400N V2 and Intel 5300 AGN can't connect at N speeds

Hi,
I have a Dell Latitude E6500 with the Intel WiFi Link 5300 AGN adapter. I cannot get it to connect to my WRVS4400N V2 at anything higher than 54 Mbps. I have downloaded the latest driver from Intel and N mode is enabled. Has anyone else managed to get these two to work together?
Thanks in advance.

I am having the same problem as kirksaban. I have an HP EliteBook 8530p with an Intel 5300 AGN. It can detect my WiFi network from the WRVS4400N is 802.11n, but it will only connect at 802.11g speeds. We have both an older and newer MacBook Pro that both can connect faster than 54 Mbps, but the HP will not. I checked the product brief on Intel's site and it claims the 5300 AGN will operate at both 2.4 GHz and 5.0 GHz (I will try to paste URLs below). Where did you find it would only operate at 5.0 GHz? Are we sure the band on the 5300 AGN is the problem?

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

Just though I would Hare it with the Community

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.

3 Antenna of WiFi linking to 4965 AGN problem.

I just brought a Intel 4965 AGN wifi card to upgrade my T61 which does not come with any wifi when I got it. I cannot find any instruction on how to connect the three antenna wires to the right spot. There are three color wires, Black, White and Grey, and there are three pins, 1, 3 and 2 from left to right on the card.
After I done some research on the web, I found serveal versions of ways of connection, which are all different.
1) From the T61 Hardware Maintenance Manual, it told me the order should be Grey, White, Black. I thought it should be the right answer, since it's from the authority manual, however the signal is not so great.
2) From other popular laptop forums, I found many people believed it should be Black, Grey, White
Totally confused. Anyone who happend to own a N wifi card on T61 could have the right answer?
Thanks,
Jian

BTW, this card is not buying from Lenovo, so it is not a "authorized" wifi card. It has 1802 error when the first
time turn on the laptop. I found some hacked BIOS update software to rewrite the BIOS. It was the perfect
version. Unlike some of those versions, it not only can ignore the 1802 message, it also can enable the wifi indicator light and FN+F5 button can turn on/off wifi in the system. Just works like a real "authorized" card. Saving a lot for not
been rip off buying overpriced accessories from Lenovo.
