Netgear Orbi and Intel ac 3165 minor issue

I have an Orbi system running in my house and everything has worked very well with great coverage and speed everywhere (even when we have family parties and there are about 50 devices connected to the wifi system).

I recently got a new Dell laptop and in the set up process, I ran into a small issue.  There are two websites that will not load properly/fully when laptop is connected to the Orbi wifi system.  All other websites do load properly.  This is the same for Edge, Firefox and Chrome.

The laptop is running Windows 10 Creator and the internal wifi card is an Intel ac 3165.  Everything has been updated (OS, drivers, firmware, etc).

The kicker in all this is that everything works very when:

  1. Ethernet cable is used
  2. A cheap USB Wifi dongle is used (with Orbi wifi)
  3. A different router and wifi system used

Thus the issue is a communication problem between the Orbi wifi and the Intel ac 3165.  Any suggestions?

    Hello Krf007

     

    Have you tried to go into the wireless adapter settings on the laptop and change the DNS server?

      Thank you and yes, I had changed the DNS and even just tried that again.  I have upgraded and re-installed all drivers and updates and it just work for the two specific websites.  All others work.  I even put a different wireless router hooked up by ethernet from the Orbil router and that wifi works fine for the two websites (same DNS).  This is a hard one tto figure out.

      Yes, I have tried different drivers.  Have gone through extensive uninstall/reboot to clear out any remnants and deleted temporary files and then installed updated drivers.  It did not help.  I had posted this issue on Dell support website (it is a Dell laptop) and on Intel's support website also.  I have tried all of theri suggestions as well.  

       

      The Intel 3165 wireless adaptor is a 1x1 antenna arrangement and I am not finding a similar shaped wireless adaptor with a 1x1 antenna.  All the newer ones I find are 2x2.  I may try a 2x2 card when I have some free time.  I also see that I can get a new 3165 for less than $10 on Amazon and may just try that as well.

        I had contacted both Dell (laptop manufacturer and Intel) in regards to the problem I was having.  Dell just wanted me to update everything and then said it was an Orbi issue.  I disagreed since all the other wi-fi devices worked fine and I had no issues with them.  Intel responded back with a few suggestions (uninstall and update drivers for the 3165).  I sent a not back to Intel and the next day, they sent me a note with a couple of new things to try and stated that there were a few folks that had the newest update of Windows 10 having the same problem.  I went through the steps and EVERYTHING works great.  Here is what Intel suggested I go:

        Intel told me to go in powershell as administrator. Windows 10 Creator has an option to run Poweshell as Administrator when you right-click the start logo. 

        Then you need to fine the name of your wi-fi adapter: get-netadaptor

        My adapter name is wi-fi.

        Then you disable the RSC (receive segment coalescing)

        I disable the RSC by typing in: disable-netadapterrsc –name wifi

        Intel next suggested setting the wi-fi adaptor MTU to 1400.  I used the command below to find the highest MTU that did not return fragmented files.  1400 still returned fragmented files.  1300 did not, 1350 did not.  1375 did return fragmented files.  Thus I went with 1350.  The optimum number is somewhere between 1350 and 1375.

        I found the correct mtu by typing in: ping www.google.com –f –l xxxx where xxxx is the mtu size going down until the ping packets returned were not fragmented.  I started with 1400 and eventually settled on 1350.

        I set the mtu for the adapter by typing: netsh interface ipv4 set subinterface “wi-fi” mtu=1350 store=persistent

        It all works.  Thank you.
