U350 / Intel 5100 AGN problems

I have a u350 w / windows 7 and I have wifi low speed, packet loss and disconnections.

I have a good Cisco AP (802.11 g) which works well with my other two laptops.  Usually sitting side by side, the other laptops will be 54 or 48 MB/s and will download a 700 MB file approximately two times faster from a local file server.  I got the ap and other laptop for months and never had disconnected in my house before, but I lost the signal several times with the u350.

I also bought a shit linksys wrt610n to go with the new u350, none of the other devices support N then I mounted this thing exclusively for the u350.  I get usually anywhere 2-5 Mbps on the AP N but sometimes speeds up to 24mbps.  I played with different parameters on the AP as 5 ghz, 2.4 ghz, or both at the same time, but it's pretty crappy and slower than G each time.

Because I have two access points and other laptops, I'm sure it's just the u350 which is screwed.  Forget 802.11n, I'd be happy if I could use the u350 with my G Cisco without be disconnected and abandonment of packages left and right.

Is it possible that I have a bad wi - fi card or could it be just a software problem?  I tried the driver lenovo and the new intel / microsoft one and they have this problem.

Disregard that, I took it apart and found the antenna cable was loose.  Now I'm getting 54 Mbps on G and 216mbps n.

  • Alternative to wireless Intel Wifi Link 5100 AGN card?

    I find that my Intel 5100 AGN wireless network card does not work as well as he used to.  I tried everything... even the drivers are perfectly up-to-date.  But I keep losing the connection to my wireless router, even if the strength of connection between 3 and 4 bars.  I find that I rarely make me fall if I have 5 bars.  But if it drops to 3, I get periodically fall any wireless network that I use.

    I want to replace this card by something better, but of course compatible with the HP dv5 (my specific model is dv5t-1000).  Any recommendations?

    "If you keep an open mind, life will give you more opportunities."

    Hi, Gary:

    What I meant by my statement about you have the best of the cards available for your laptop is that, Yes, I'm sure that the Intel 5300 is an improvement on the 5100, but the problem is that you can not install the 5300 in your notebook.

    The Intel 5300 is not supported (only the numbers of cards/coins listed in the service manual can be installed) and your laptop wouldn't start until you have removed the card.

    You can try another card in the manual, if you wish.

    However, you are limited to the:

    4322 Broadcom 802.11a/b/g/n WLAN module

    Broadcom BCM4312 802. 11 b / module g WLAN (not a N Wireless card)

    I guess you can use an external USB adapter, but I would like to get one with an external antenna connected to him, because I would have to believe that installing wire of 3 antenna in your address must provide superior reception on a simple USB wireless adapter with an internal antenna as its single antenna.

    The antennas go all the way to the top of your screen.

    Tinker you with advanced network adapter settings?  They can be found by clicking on the card in the Device Manager, click the Advanced tab.  Take note of where the parameters are now so if something is buggy, you can change their return.

    Here is a guide to the advanced settings that you have and the recommended settings for them.

  • HP ProBook s 4710: Bluetooth missing on HP ProBook 4710 s (Windows 7 64-bit) - Intel WiFi - Link 5100 AGN

    Hello

    I have a strange problem:

    I have two HP ProBook s 4710 here in front of me. The two "seems" to have the same hardware inside (I don't see any difference on the stickers in the back).

    I have install both of them with the same USB with Windows 7N 64-bit.

    After the installation is complete (no additional driver installed).

    the first bluetooth ProBook has

    the second bluetooth ProBook has NO!

    I checked the BIOS, every two active a bluetooth settings on both.

    WLAN works on both.

    On the first s I can also install the bluetooth drivers latest, on the second, I can't. Always the message occurred ("no device was detected. Make sure that... »).

    Device Manager indicates, the two ProBooks Intel WiFi - Link 5100 AGN, the first s also Bluetooth-device listed, the second of not.

    What the hell is going on here?

    Hello:

    It is very strange because the HP Wireless Assistant software is registered directly on the support page and driver 4710 under the solutions section.

    If this is the case, try the latest HP Connection Manager software which does the same thing the software assistant wireless.

    Here's the theory behind your dilemma (except radio BT died).

    This laptop once had the connection manager (since the software assistant Wireless does not) installed, and you can use this software to individually disable bluetooth or devices rather than using the wireless button wireless.

    I guess that for example, turn off the stereo bluetooth with the connection manager to save a small amount of battery power, which increases the time before having to recharge the battery.  But you can still use the wireless.

    The hardware button turns both off the coast.

    The big problem is...

    If none of these devices are turned off by the wireless assistant or the connection manager software and that you reinstall the operating system or to update or other, wireless or bluetooth devices do not appear in the Manager of devices as if they are dead or don't exist.

    And what makes this more puzzled, is that if you check the BIOS, you will see that they are present and active!

    The only way to make them work again, is to turn them on by using the Deputy Director or the wireless connection software.

    This is why it is absolutely essential to ensure that these devices have been turned on before you reinstall the operating system.

    For those people that upgrading to W10, none of these programs work on W10, so if the BT has been disabled, the user must return to W7, activate the bluetooth, uninstall the connection manager or the wireless assistant software, reboot, ensure that the device is always on and then upgrade to W10.

    Here is the link to the software of the support page for your laptop connection manager...

    FTP://ftp.HP.com/pub/SoftPaq/sp53001-53500/sp53394.exe

    If this doesn't work or the other, I suspect that the BT module does not work (all hardware failures).

  • Problem with T500 Intel 5300 AGN WiFi fixed...

    I finally found the solution to my problem today, and I write this information in the hopes that someone can verify in their environment, what I found in mine.  Also in the hope that it will save someone else the weeks of effort it took resolve.

    To summarize, my problem was that I was able to stream audio or video from my local network or from the internet without losing connectivity frequently or permanently.  This problem started when several months ago I updated my laptop for Win 7 Professional of Vista Business.  I don't meet with the problem in Vista.

    Today, I have determined that the problem is that I am under mixed mode on my LAN that is apparently supported by Win 7 for the Intel 5300 driver.  My router is D - Link DIR-655, which is a 802.11n router can be configured for mixed mode support.  I'm running that he configured for support because my wife's cell phone supports n and g as g.  I booted up my laptop today and I began an audio stream from my server and to my surprise it worked perfectly, just as it should.  I listened for a while and all of a sudden the music started to jump.  I noticed that my wife had started just his cell phone around the same time the jump began.  On a long shot, I went to the advanced configuration of the 5300 and disabled 802.11n support forcing them to disconnect and reconnect to 54 Mbps.  This action restored my audio stream immediately and I progressed to test several LAN and WAN connectivity actions (browser, e-mail, etc.) which previously guaranteed a discontinuity in the flow.  Everything continued to work exactly as you would expect.

    I feel that the problem is with the driver 5300 rather than my router because to solve the problem, I have disabled 802.11n on the 5300, not on the router.  The D-Link still works in mixed g/n mode 802.11.  Also, I have a laptop Lenovo T61, which also has a good Intel WiFi AGN adapter to a different model.  This laptop works in n mode with no connection problems, either via the same router D-Link.

    I hope that someone else on this forum allows to reproduce my results in their LAN/WAN environment to confirm that there is a problem with the driver Win 7 currently available for the 5300.  Thanks to Lenovo technicians, who spent several hours on the phone with me and even sent me a new adapter 5300 at a time, thinking that maybe the problem.

    Okay, more than 24 hours now without any problems, 2.4 ghz and full rate of 270/300.  As with the GSM card, I tried the latest vista driver intel 5300 and poof, no problem loading.

    I decided to do so after testing with some dual-band routers.  I noticed that it worked well on 5 GHz, but if it is locked at 2.4 it had problems with all routers.  It also worked well with dlink adapter USB N on 2.4 ghz.

    Since he had worked in vista with 2.4 ghz, I decided to try this driver and was able to put all the settings back to full (power transmission, optimizations, etc.).

    13.0.0.107? seems to have a bug of driver at 2.4 ghz.  The exact version is 12.4.4.5.  So far I have found no side effects (except without freezes or crashes on the 5300).

    So, hope this works for others, if all goes well, next version of the driver it will solve, but mine works fine for now.

  • WiFi link 5100 AGN

    I get the "dysfunctional" message that the WIFI link 5100 AGN has a driver problem... I am running Windows 7... Troubleshooting DIFFICULTY IT has failed.  Could someone enlighten me also as to how it affects me?  I didn't notice anything in particular up to now.

    Thank you very, very much... I visited the two Intel and Dell... ran a diagnostic on Dell... then downloaded 'detector and installer for drivers' who came through good but later... much later said he finally was able to download this driver but can not install it.

    I tried several ways to download the driver from the website, but nothing is done and finally did what I probably would have done FIRST... a system restore to before that happened... but I thought that I better try to "fix" or "Reinstall" the driver anyway then came to the Community Council.

    Well, the final result is because the restaurant is back to before the problem, but I still don't know what happened to do in the first place.

    Broadcom 4312, 4322 Broadcom, Broadcom 4321,

    Intel 5300, Intel 5100

    I want to replace the current wireless (Broadcom BCM94312MCG) on an Intel 5300 AGN card because the latter supports 802.11n.

    So, my BIOS supports supported than the next Intel 5300 AGN cards:

    Hello

    You tell us where you found the recommended update.

    ________________________________________________________

    FYI for Windows updates:

    Microsoft gives sometimes you updates for the 3rd party hardware: graphics, network cards, etc.

    You should only get the latest drivers for them to real hardware manufacturer's website, as Microsoft normally does nor those have the most recent drivers available as Microsoft relies of the 3rd party hardware Manufactuer to provide.

    But unfortunately, the only way to know which is the update of the problem is to install them one by one, until you find the 'wrong' for your installation.

    You can do a system restore to get back until it has been installed (which is NOT the best way to remove an update) or follow this method:

    'Remove an update'
