How can I update to network without WIRE Draft 802.11n draft 5742z-4200 adapter

I have an Acer Aspire 5742z-4200, and it came with a mini PCI-E card of draft 802.11n.  I didn't need much in the way of transfer speed out of the machine most of the time I've owned it, but now all of a sudden.

I bought two Inetl 802.11 b/g/n/ac cards, assuming that the PCI-E was a standard housing, and one card would work, like the other, but with different capacities.  That doesn't seem to matter of bethe.  After installation of each, the PC started very slowly, but has managed to load network tot connect drivers and even transfer files at lightning speed, compared to my connection 802.11 g.  But overall, the laptop is too slow to use.

A little research on Google introduced me to the term 'material whitelist.  I imagine that it is also possible tensions, frequency of the bus or whatever it is of another participant might be incompatible.  The PC works fine with the old card in it, so I don't think I have anything damaged.  Does anyone know what I need to do to upgrade the WLAN card in my laptop?  If I'm relegated to get a USB adapter?

Thanks for your help!

OK, some more application of Google-fu, and I read more on the subject of the registration of the pins with more recently introduced functions.  Pin 20 seemed to have something to with a wireless radio turn off the feature that did not have previous PCIe slots/motherboards.  The symptom seems to be no visible from card otherwise functional networks.  PIN 51 resembled a new feature/issue and seemed to have something with the ability to disable the radio more than one.  (The 802.11ac card I got a bluetooth as well.)  It is manufactured by chipzilla, a nd a 2.4 and 5 Ghz frequencies for WLAN function. I wanted the frequencies and the 802.11ac and struggled to find one without Bluetooth.  It was $ 31).

This PC is quite old now (Core 2 Duo 2 Ghz, DDR3 1333 MHz RAM - a bit slow, but with a small SSD, it's fine for my purposes.) and not worth much and I save all the time so I decided to give it a shot.  I don't know the rules here to post links, so I don't want to, but they are not hard to find.  A few people have even posted revision of the Chipzilla official on the mini PCIe spec for the addition of several start/stop function triggered on the PIN 51 radio.  PIN Ribbon 51 seems to have solved the problem completely.

Yet now my machine starts quick, the transfer rate WiFi is what it should be and if I don't have any Bluetooth use, the devices all appear OK in Device Mangler.  I guess that all 802.11ac cards with several radio stations have this PIN 51 - multiple radio disable switch compatibility issues when used in older laptops.  I look around a bit for one with no Bluetooth, but saw nothing so I decided to try the hack.  If the thing starts to smoke or whatever it is, I'll come back and update this thread.  I wouldn't spread dangerous advice.

Thanks again, Chris.

  • How can I update the view without freezing?

    Hi all

    I am trying to load more items in a list, as does the Twitter app

    When I want to load more items, I have done the following:

    • I shows Loader
    • I do the networking activity
    • I'm updating the view

    The problem is that the application UI freezes during the stage of "update view" (for 2 or 3 seconds).

    Because I'm not in the main thead element I update the gwendoline in the following way:

    UiApplication.getUiApplication().invokeLater(new Runnable() {
                public void run() {
                    synchronized (UiApplication.getEventLock()) {
                        while (MyList.hasMoreElements()) {
                             ...
                              ScrollableList.add(item);
                              ...
                        }
                         hideLoader();
                    }
                }
            });
    

    Is it possible to update the view without fix it the interface?

    Thanks to you all.

    Welcome to the support forum.

    invokelater enough, you don't have to synchronize the lock of the event.

    I don't know what is ScrollableList, but if you want to use a ListField, for example, you can add all the entries at a time.
    Even in other cases, as a normal Manager, addAll could be much better performance.

  • How can I update the BIOS without using a CD?

    Hello!

    I recently decided to update my RAM from 2 GB to 4 GB. After installation, I started my computer to find that it would not recognize the new memory. After doing some troubleshooting, I decided to try to update the BIOS, like the 2010 version. I have downloaded the update to the BIOS boot CD implementation of lenovo, burned a disk and restarts, I found that the boot order has no CD contained thereon. Here's the catch: I do not have the supervisor password. It is a mobile phone in hand, and I tried to find the password nothing is done. It's the current boot order: USB key, hard drive.

    My question is, can I create a BIOS update disk using a USB key, or update the BIOS of another way?

    I understand that it is impossible to recover the supervisor password without having served (that I prefer to not do, even if I have to return my Crucial RAM)

    My system features:

    ThinkPad L512

    BIOS version: 1.04

    BIOS date: 2010-3-26

    Controller of Embeded Version: 1.01

    Windows 7 32 bit

    Thanks for your help.

    Welcome to the forum!

    Two things here:

    (a) If you run the system update, it should offer the latest BIOS for your machine as well. I never did on a protected device, so it may or may not work, but perhaps worth it.

    (b) I doubt the ability of the system to recognize the new RAM has something to do with the BIOS. Much older than your ThinkPads will take place 4-8 GB of RAM with an old BIOS, older than your machine initially.

    Good luck.

  • How can I update the BIOS without windows on V3 - 372

    I bought an ACER V3-372-57CW and refuses the computer at startup (the Green ACER splash screen at boot EFI appear same) when my Tablet WACOM Intuos 4 (if not fully functional) is inserted any USB port. Customer service Acer not recognize wanted to nor register the question so my last hope is that a BIOS update will solve the problem.

    I'm used to the manufacturers supplying utilities executable flash BACK running under FreeDOS etc but for the Acer V3 - 372, I can only find an executable for Windows 10. Of course, uninstalling the entire system just for the update of the BIOS is not a viable option.

    Is it possible to get either one executable for the update of the BIOS BACK or something that could be used from within Linux (with EFI)?

    Thank you

    Masquilier,

    At the present time, I have installed on my Windows computer.  If someone were to tell me that I needed to install another operating system to update the BIOS, I don't think it was a big deal.  I would like to...

    1. create a system with the Windows image backup

    2 clean the clean disk with 'diskpart '.

    3. install any OS they told me that I had to install.

    4. update of the BIOS

    5. after updating the BIOS, I would just wipe the drive with diskpart and restore my Windows system image.

    6. it would take me less than 45 minutes to accomplish steps 1 through 5.  Probably about 30 minutes to be honest.

    Use my logic.  Except that I'm not a Linux expert and don't know how to do what I tell you with Linux.  Just google it.  I see that some people use clonezilla, but I don't know there is a command to do the same.

    Important note: own Diskpart is priceless, if you n-front-rear of switching between the old modes and UEFI... or deleting partitions... or clean installation of an OS.  However, make sure that you don't accidentally wipe the bad drive (drive).  Be careful.  There is step-overs.

  • Can't see the networks without wire in Dell Inspiron

    I have just moved house (previously in the United Kingdom, in Australia) and now I can't get my Dell Inspiron 1525 to find (Vista 31 bits operating system) wireless networks. Under network and sharing Center, if I click on connect to a network or setting up a connection or network, nothing happens. Similarly, under Manage Wireless Networks if I select add nothing happens. However, if I select the Dell Wireless WLAN Card Utility I see my network wireless on the Site tab. Also, I can see and connect to the network wirelessly to other devices (for example the iTouch).

  • How can I update the UI without encountering a ' Application is not responding do not; completed process '?

    I'm trying to populate a table on the screen, and when the user clicks a Labelfield (20 lines are populated by click).

    When the user clicks the labelfield, following takes place:

    (1) a data segment is read from the SQLite database in a background thread.

    (2) data are then filled in the existing table on the screen (by adding more fields to the Table Layout Manager) in the invokeLater() method.

    I am currently facing a problem of ' Application is not responding do not; process is completed ' when I continue to load more items to say about 3 to 4 times (i.e. After about 60 to 80 lines are met).

    I fear that this could be caused by the user interface thread get resisted for a long time, while the population takes place. Is there another way to update the user interface, so that the application runs smoothly?

    I'd appreciate any help that I had with this problem for some time.

    You must use another thread to query the database and then creating and filling in the fields. After the creation of fields use the Manager.addAll () method to add an array of fields (in invokeLater() body of course).
