Inspiron Intel Wireless N 7260 with POOR performance

The laptop was purchased 8/2014.  I'm having problems with my WIFI connection and our cable service provider out today.  They have isolated the problem to the laptop.  They proved this by running tests of speed on different devices.  This laptop was the only device that produces slow download speeds<6 mbps="" while="" the="" other="" devices="" are="" running="" anywhere="" from="" 50="" mbps="" to="" as="" high="" as="" 90="" mbps. ="" if="" i="" connect="" this="" laptop="" via="" ethernet="" it="" runs="" in="" the="" 90="" mbps="">

WIFI on this device is an Intel Wireless N 7260 and the 16.6.0.8 driver version runs at 2.4 GHz only.

Does anyone know if this is faulty (it passes all the tests) or is it something that needs to be upgraded already?  Y at - it an upgrade?

jjdeadhead,

Did you recently install/reinstall/upgrade the operating system?

Have you tried the drivers from the Dell website? Go to drivers and downloads , enter your service tag, select your operating system, network, download the drivers and save them to your desktop.

Do a system restore point.

Go to Device Manager, network cards, click with the right button on the Intel® Dual Band Wireless-N 7260, left, click on uninstall. Tell him to remove the software and drivers. Then, restart your computer. When you connect, the new hardware wizard will try to install the drivers. Install the drivers that you saved on your desktop.

Try these tweaks...

Start, Control Panel, Manager of devices. Click Network and then right click on your network adapter, on the left, click on properties, power management. Uncheck the allow the computer to turn off this device to save power.

Go to the options power and changed the wireless adapter setting, adjustment of maximum power for maximum performance.

  • VM with poor performance (CPU)?

    I have a virtual computer that runs 'wrong'... checked esxtop for all relieved symptom but found nothing.

    Average usage of the CPU to 2 vCPUs is about 50% and more...

    Checked with performance, the swap file usage monitor, but the file is not used, use of memory 2 GB to 3 GB... of ideas?

    PrintScreen of my VM in esxtop is in attachment (the name of the virtual machine is not visible)

    The post said two vcpus.

    I might try the virtual machine with one vcpu and see if this improves performance.

    Hi all

    Database version: 10.2.0.5

    I'm working on a new report to view the top users by the number of calls. The table is truncated and filled again every month with records for the previous month; It contains approximately 400 000 records.

    I created a view with the columns needed for the report; also, the two functions of view calls to determine if a phone number is assigned to multiple staffs or several departments.

    It's full again table every month:

    These are the functions to determine if a phone number is assigned to multiple staffs or departments:

    FUNCTION GET_EMPLOYEE_NAME (P_FROM_FULL_TELEPHONE IN VARCHAR2)
RETURN VARCHAR2
AS
  L_NAME EMPLOYEES.NAME%TYPE;
BEGIN
  SELECT NAME
  INTO L_NAME
  FROM EMPLOYEES
  WHERE WORK_PHONE_1_FORMAT = P_FROM_FULL_TELEPHONE;
  
  RETURN L_NAME;
EXCEPTION
  WHEN TOO_MANY_ROWS THEN
    L_NAME := 'Multiple Employees';
    RETURN L_NAME;
  WHEN NO_DATA_FOUND THEN
    L_NAME := 'No Employee Assigned';
    RETURN L_NAME;
  WHEN OTHERS THEN
    NULL;
END;


    FUNCTION GET_DEPARTMENT_NAME (P_FROM_FULL_TELEPHONE IN VARCHAR2)
RETURN VARCHAR2
AS
  L_DEPT_DESCR EMPLOYEES.DEPT_DESCR%TYPE;
BEGIN
  SELECT DEPT_DESCR
  INTO L_DEPT_DESCR

  WHERE WORK_PHONE_1_FORMAT = P_FROM_FULL_TELEPHONE;
  
  RETURN L_DEPT_DESCR;

  WHEN NO_DATA_FOUND THEN
    L_DEPT_DESCR := 'No Department Assigned';
    RETURN L_DEPT_DESCR;
  WHEN OTHERS THEN
    NULL;
END;

    This is the point of view that I'll use in the report:

    It's to you if you are satisfied or interested in improvements (if possible).

    If so the first thing I would like if you had your refreshed perspective as advised. According to expected area_code table cardinalities I doubt.

    So, if not cool off with dbms_stats.gather_table_stats on two tables, area_codes and MONTHLY_BILLING_DETAILS.

    Bottlenecks are now obviously the full table of MONTHLY_BILLING_DETAILS as well as the ANTI of LOOPS IMBRIQUEES scan.

    At the moment I don't think that an index of MONTHLY_BILLING_DETAILS will help a lot, because most of the lines will pass filter predicates, and because we need some columns in it, I have now I there will be gain a full index scan.

    I was surprissed that the optimizer pushes the substr <> predicates to both tables.

    So depending on your data, you might try

    1 make a factory of subquery select the two MONTHLY_BILLING_DETAILS columns that all directly apply predicates of membership and use it directly in the join instead of the table.

    or

    2. If all subtr to so are part of the table area_code choose in it using a subquery (or inline view) plant excluding these values.

    Both are attempts to get rid of the substr excluding as filters of join predicates.

    In fact, I was expecting a hash join anti as shown in the plan to explain instead of the nested loops anti, I expect to be more effective in this case.

    Perhaps with correct cardinalities the optimizier would understand himself.

    Just to test it, you can try the use_hash hint in the join:

    Select / * + USE_HASH (MBD, one) * /.

    ..

    OF MONTHLY_BILLING_DETAILS MBD,.

    NYNJ_METRO_AREA_CODES one

    (It's a good habit anyway usually use aliases and precede the names of columns. In the, it is easier to read queries are only trivial).

  • Intel Wireless WiFi Link 4965AGN with Inspiron 1525 problems

    I have Inspiron 1525 + 8.1 Windows + Intel Wireless WiFi Link 4965AGN (Intel last driver for Windows 8). If I set the off mode N card wifi, wifi is more slow (54 Mbit/s), but stable. If I turn N (enable) mode, wifi is fast 144 Mbps, but becomes unstable - often (few minutes) disconnects, the disconnection of the card shows a lack of drivers, you cannot reconnect to the router, you must restart your computer. Another computer - Dell Studio with pre-installed map 5100 is stable under the N on my home network. Dell officially submitted the 4965AGN card is compatible for Inspiron 1525. Is it possible for stable operation in N mode?

    waltur,

    I'm glad to hear that you were able to find a solution to your connection problem. Thanks for posting back.

    Take care

  • Intel dual band wireless-ac 7260 Compatability

    I just bought a new HP Pavilion and want to upgrade the wireless LAN card. It of a great PC and has an i7 Intel Core 4 Gen and so far works fine when connected to my LAN via Cat6. I'm having issues pulling large CAD files and in looking over the repair, the only option listed for a duel card band is an old N Intel 3160 (1 X 1), from 2013. I contacted Intel and was informed that the card should work, but that HP tends to Whitelist BIOS here to prevent customers of workstations being upgraded there. The question that I have is the the 7260 Intel does not appear in my service manual, BUT is currently available for download driver on the support listed as a driver Intel 7260/3160 site. Anyone know if this product is in the white list on the BIOS? I have listed the part I'll order below for reference.

    INTEL DUAL BAND WIRELESS AC 7260 - (NETWORK CARD 2 X 2

    HALF OF MINI - PCI EXPRESS CARD

    802. 11B, 802. 11A, 802. 11 G, 802.11N,
    802.11AC, BLUETOOTH 4.0

    Model number 7260.HMWWB. R

    TigerDirect part number: IE2-102594433

    List price $29.99

    As you can see the value of spending $29.99 and the return on investment of this offer that it is obvious, from the 'stocks' Realtek Wireless Card that comes standard on this computer.

    Would also like to point out that this computer was only $479.99 at Best Buy and came with and i7 4Gen and was too good to pass up.  No idea why HP would be but as lower wifi card in the same workstation with an i7.

    Thanks in advance for taking the time to read this post and I can't wait to read your response.

    Hello:

    Several posts, I read on the forum that you should have no problem installing any wireless card you want in your laptop, as it appears that HP has done away the white list of wireless cards BIOS.

    Here is the link to the service manual for your laptop.

    Info upgrade memory are in Chapter 1.

    http://h10025.www1.HP.com/ewfrf/wc/manualCategory?cc=us & dlc = in & lc = in & product = 7582630 &

    Now, I have bad news for you...

    You will cancel the warranty if you install a wireless card or memory yourself.

    Unfortunately, you have to pretty much disassemble the laptop everything to the hard drive, memory, and the wireless card.  You can refer to chapters 5 and 6 of the repair for the removal and replacement procedures.

  • Satellite P850 - 12 X - update Intel Dual Band Wireless-AC 7260

    Hello

    I'm writing this information for those who want to upgrade their wirelss adapter inside the Intel 7260AC card dual band.

    This card functions perfectly on my Satellite P850-12 X, but you will need to cover the pin 20 with a piece of tape so that it works correctly. I installed this card in my laptop, installed the drivers etc, everything went well past shown in dev Manager without problems, but them was always a red x across wireless networks connections and nothing would show. After spending several days trying to figure out what the problem was, I came across this information I share now. I will not go, why you need to cover the pin20 which would take a whole new thread.

    The intel 7260 dual band wireless card works with incredibly fast speeds and has a capacity of Widi and bluetooth and is well recommended but iff after the installation of the card that you have similar problems, as I had then you now have the soloution I saved days of reasearch. All donations most wecome :)

    http://www.InsanelyMac.com/forum/topic/279398-solved-where-is-pin-20-on-a-WiFi-card/

    Hi Sam

    Thanks for sharing your experience.
    I just want to add that these updates is not supported by Toshiba and these updates probably will void warranty valid. This should know any owner of the laptop and do these updates on his own risk.
    With other words each of us must know this and make own decision how to handle this situation.

    In any case, I m happy to know that everything went well with your upgrade. :)

    Good luck.

  • Poor performance wireless on Qosmio X 500 - 134

    I just bought a Toshiba Qosmio x 500-134, and there is one thing that bothers me. The wireless connection is very poor.
    HE can say that I am very disappointed with it. I had a model x 205-sli1 front and the Wi - Fi connection was top.

    Why x 500 is so poor?

    What do you mean with the poor? Slow or what?

    Who knows what you do, what WLAN settings that you use and how test you the performance of WLAN.

  • Pavilion G62 b04SL: upgraded to an Intel Dual Band Wireless-AC 7260 default wifi card

    Hello, my laptop Hp G62 b04SL 2009 can support an Intel Dual Band Wireless-AC 7260 wifi card?

    Have this laptop, a whitelist (or black)?

    profuct key: XF299EA #ABZ

    Processor: Intel Core I3 350M

    motherboard: HP 1439 60.50

    BIOS: version of Hewlett - Packard F.48 09/11/2011

    RAM: 4 GB

    Thank you all!

    Yes, he absolutely has a whitelist. I do not know where to come from tips in the other 2 posts and this is a mistake. Laptop wi - fi modules are readily available on the market. I have a drawer full of them to prove it. Unfortunately, HP had about one year-10 ran to block the installation of any wi - fi (module) card but a specific group of cards specific firmware HP and identity. In other words, the ONLY cards that can be installed are the very specific listed for your model in your area in the maintenance manual. This prevented the owners of manufactured HP laptops before about Q4 2013 to upgrade to the latest wireless technology. Your laptop is longer than that if you're stuck with what is indicated in the maintenance manual.

    Not my decision, just tell it like it is.

    Check your wireless card form factor.  Instantly, it shows the old style card, and on that, it shows the new style half mini-map.

    You will have one or the other.  Only one of form factors will work.

    In addition, HP has removed this restriction of starting BIOS about a year to 15 months.

    I bought a HP 350 G1 in February, and I wanted to mirror screen my PC, but does not support the wlan card, he had.
