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 th...
hi
have you tried different drivers for the intel ?
see
https://downloadcenter.intel.com/product/89450/Intel-Dual-Band-Wireless-AC-3165
or prehaps the laptops manufactures support website download
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.
nice bit of fault finding and i must say wow , would never had thought to go down that road , if you dont mind im going to pass this onto the dev team as it may end up solving a whole crap load of issues
cheers

Pete,
By all means, pass on the info. I noticed that I do have a few typos in my list of activities. If you want a corrected copy, please let me know. Also, look at my reply to the cooment after yours for some new info.

Did you try setting the MTU to 1350 on the Orbi WAN interface, and then resetting the 3165 MTU back to the normal 1500?
If that also works, perhaps trying re-enabling RSC and see if that piece actually matters.
This morning, I set the Orbi MTU to 1350. Before I adjusted my laptop intel 3165, I did a quick check of our iPads and they did not work for several of our TV apps. Reset Orbi back to MTU 1500 and all works on the iPads.
I did go into my laptop and re-enabled the RSC "enable-netadapterrsc -name wi-fi" and everything works fine. Thus, in my opinion, the Intel problem was with the MTU.
I will leave the Orbi set at 1500 MTU for now.
