    Slow speed intel dualband AC-7260 (HMW)

    intelproask

      hi

      i have a strange problem with my intel wifi card in Acer V3-772g win 8.1 64bit.

      before that i had a Qualcomm Atheros AR5BWB222. but becz of WiDi upgraded to this intel. my friend has same laptop, same card, working ok!

      after fresh installation of intel driver and software i had the usual speed (60Mb as my provider) and afters several minutes it started to get slower, and now after several restarts, suggestions in forums, installations just slow.

      what i did as solution:

      - try other driver versions (currently the last version 18.33.11.2)

      - turn on/off/disable bluetooth

      - switch cables

      - of course i removed BT and wifi from last card clearly!

      - contact my provider, and checked the connection to my modem. everything ok, as expected.

      - tried some settings in modem like changing channels...

      - change some settings in wireless adapter

       

      any idea? any similar case?

            so i guys, after some experiments and calls, im back.

            it seems to be a silly problem. It (was) a silly "problem".

            i found a way (correct way) and tested it several days to be sure. So, what was the problem? :

            +++ Dont f***ing use WifiInfoView while u r checking ping or speed test. This program jams your bandwidth! +++

            i tested it on 3 different wifi adapters/laptops. same results! this software impairs the bandwidth.

            why i used this software? so, i decided to change to an intel wifi card to get whole potential of my system, specially WiDi. so i removed my default (Atheros) wifi card and installed new intel 7260. then i was so interested to know, which band my device uses and signal quality and some other details about my wifi/modem/quality blabla... WifiInfoView shows it.

             

            By the Way Qualcomm Atheros AR5BWB222 supports intel WiDi, but the video (buffering) quality is not so good and as an intel wifi card. However good and strong adapter(card) with dual band and even BT;). but you cant install intel WiDi software ("your device doesnt support intel WiDi blabla...") though this atheros card can cast screen using intel WiDi though not listed as "System Requirements for Intel® Wireless Display (Intel® WiDi)".

             

            another thing which must be noticed: im just using wifi service. i've not used/tested the bluetooth service of intel 7260 yet. intel BT driver not installed (just default microsoft driver from 2006) and i've disabled BT in device manager. Why?

            1) i dont trust intel BT service (especially 7260) and im not interested to experminet how BT affects my wifi performance (im busy and within exams time...). as you know intel 7260 has some BT issues in some laptops! like interrupting wifi performance OR even unstable or not recognized BT (just search "intel 7260 BT pin 51" hahahahaha. you will find many funny problems/solutions).

            2) i actually dont use BT. im ok without it!

            Conclusion/ Summery:

            - the software "WifiInfoView" jams wifi performance for (probably) all wifi card brands. (link below)

            - Qualcomm Atheros AR5BWB222 supports WiDi (i think unofficially) but has light quality disadvantages.

            - Acer Aspire V3-772G supports intel dualband AC-7260 (HMW)

            - i have not tested the Bluetooth of intel 7260 yet. i cant report any thing about recognition/stability/performance ....

             

            thx a lot to intel support team and community. i hope i could help some future users by searching this issue in google.

            by the way, i hope my wifi performance stay as like as it should be like now. wifi card is just newly added to my laptop, if some new strange problems occur, will be reported!
