Hello I have a Dell Inspiron 15 7000 model number #7537 and after having to reinstall Windows 10 I am having trouble getting my Intel Wireless-N 7260 to run in N mode.  Currently it is running in G mode and is very slow.  I have looked into resetting the QOS table on my router but this option is not listed and I do not want to have to reset my router.  I have tried to set Wifi to N mode by looking at the advanced tab of the properties but Wireless-N is not listed as a option.

-Thanks in advance

You should not need to do anything to the router. Did you install the Wifi driver from Dell's support site?

Intel no longer posts wifi drivers for this card just something called Intel Pro/set Wireless tools which is very confusing and has lot's of options.

My current driver is from 10/31/2017

I just downloaded the wife driver from Dell and it did not install because it said a newer driver version was already installed.

-Thanks

From the link  you provided they do provide the drivers in addition to the Pro Set software. If you input your service tag at the Dell Support site it will give you a list of drivers specific to your computer. Have you tried the Wifi drivers provided by Dell?

Yeah I just downloaded the Dell WiFi driver it said my system needed, and it said the newer one was already installed.

The only thing I can think of is to uninstall your current driver and install the Dell driver. You can uninstall the intel Pro Set software in Control Panel and if you still see the Wifi adapter in Device Manager uninstall it by right clicking the adapter. Reboot and install the Dell driver. Sometimes the latest driver isn't always the best.

Hello I tried what you recommended but when I rebooted it automatically updated the driver to the Intel version.  Is there a way to prevent this.  The Dell driver is listed as 18.40.0.9 and the one that's running after the reboot is 18.33.0.2.

-Thanks will try it again

You can force Windows 10 to not update drivers.

Physically, how far away is the router and how many obstructions (walls, etc.) are in the way?

What is the security type for the WiFi?  Some of them do not support N.

What other devices are connected to the router?

WiFi will automatically slow down to the fastest speed it thinks is reliable and lots of factors can affect that speed.

The router is about 20 foot away from my desk and there is one wall between it.

There is no security type listed on the router config screen and it supports N for sure because right now I as running my Wifi from a Usb adapter and it is running in N right now.

There are many other devices connected to the router, 11 devices in the device table active now and maybe two dozen not active.

"There is no security type listed on the router config screen"  Please tell me there is a password set on your WiFi; the danger of not having one is seriously extreme, these days!

If you look at the connection speed listed on the WiFi adapter's status window, how fast does it say you're connection speed is? (i.e. 54Mbps, 72Mbps, etc.)

You also said you were getting N speeds on an external USB WiFi card.  What speed does it show?

A few years ago, I had a different model of Intel WiFi that would constantly drop the connection and would sometimes be difficult to reestablish.  Your model seems to be similarly afflicted and Dell seems to be recalcitrant in admitting it, especially in Windows 10.

This model ($12.99) will pop right in and solve your problems:
